SMART LED LIGHTING CAN HELP REDUCE URBAN CO2 EMISSIONS

BY OVER 60 PER CENT: PHILIPS

cient LEDs that are connected to a cloudbased smart lighting management system. Performance data sent through existing cellular networks to help city officials remotely monitor and manage lighting infrastructure. For instance, in the evening when traffic is low, the lighting office can dim illumination levels by 50 per cent to achieve additional energy savings. In Malacca, it is stated that the new lighting system potentially offers the Malaysian state government savings of up to 80 per cent. It will also improve operational efficiencies, with less reliance on manpower for manual inspection of faulty streetlights. A new report, jointly produced by Philips Lighting and the World Council on City Data (WCCD), has revealed that cities can make energy savings and carbon dioxide (CO2) emission reductions of almost two-thirds through the introduction of smart LED street lighting. The key findings from the report, titled The Citywide Benefits of Smart & Connected Public Lighting, were shared with the United Nations (UN) during the Local 2030: Hub for Sustainability Solutions special event held at the UN headquarters in New York. It was highlighted that Los Angeles made energy savings of 63 per cent in 2016 by implementing smart, connected LED street lighting systems, generating cost savings of USD 9 million and reducing its annual greenhouse gas emissions associated with public lighting by 47,000 metric tons, equivalent to that from almost 10,000 passenger vehicles driven for one year. The report noted that better quality lighting could also reduce crime rates, with Los Angeles observing a 10.5 per cent drop in crime rates for offences such as vehicle theft, burglary and vandalism in the first two years of its LED conversion program. Other benefits cited by the report include improvements in traffic safety for road users, city attractiveness and economic strength. It postulates that by producing these benefits over and above emission reductions, smart LED lighting will also make a major contribution towards meeting the UN Sustainable Development Goals, a globally-agreed set of targets for moving to a sustainable future by 2030. Similar implementation projects in South-East Asia have also produced favourable results. In Jakarta, nearly 90,000 streetlights have been replaced with energy-effi-

THE SINGAPORE ENGINEER October 2017

Calling for all cities to adopt 100 per cent LED street lighting by 2025, Mr Harry Verhaar, Head of Global Public and Government Affairs for Philips Lighting, said, “COP21 sent a clear signal of political support to tackle the effects of climate change, and a switch to energy-efficient LED street lights in cities … with connected system management can deliver savings of up to 80 per cent, which would make a significant dent in our climate change targets.” Lighting currently accounts for 15 per cent of global electricity consumption. A universal switch to LEDs would cause this figure to fall to just 8 per cent. The report also presented a measurement framework for monitoring and evaluating city-level impacts of smart and connected lighting investments, arguing that the adoption of standardised city data such as that used in Los Angeles will help to inform infrastructure investment and decision-making and build the investment case for smart technology projects. For its part, the WCCD has been mapping its ISO 37120 standard to the 17 themes of the United Nations Sustainable Development Goals, in order to support cities in taking a leadership position to address these goals. “The ISO 37120 standard that the WCCD is implementing with cities globally defines a comprehensive set of 100 standardised indicators that enables any city, of any size, to assess their performance and measure progress over time in a way that can be accurately benchmarked and compared with other cities,” explained Dr Patricia McCarney, President & CEO of WCCD. She concluded that such globally-standardised, high-calibre data would be useful for city leaders in evaluating the benefits of smart infrastructure solutions for the financial, economic, social and environmental spheres.

LAND PREVIOUSLY EARMARKED FOR UNDERGROUND ROAD SYSTEM FREED UP FOR DEVELOPMENT In a joint statement by the Land Transport Authority (LTA) and Urban Redevelopment Authority (URA), land previously safeguarded for the Singapore Underground Road System (SURS) has been de-safeguarded and made available for development. â&#x20AC;&#x153;Enhancements to our public transport network and changes in land use policies have removed the need for SURS,â&#x20AC;? said both agencies. The full opening of the Downtown Line this year, together with the Thomson-East Coast line (2024), and Circle Line Stage 6 (circa 2025) will improve connectivity for commuters travelling from the north-western and eastern regions of the island to the CBD and Marina Bay areas. By 2030, it is estimated that more than 90 per cent of developments in the CBD will be within a five-minute walk to an MRT station. Both LTA and URA have also noted that more commercial centres have been developed outside of the city by the Gov-

ernment, bringing employment and amenities closer to homes. This reduces the need to travel in and out of the city centre. SURS was conceptualised in the late 1980s as a 15 km long underground arterial ring road system around the fringe of the city, to cater to potential The planned SURS alignment.

SATS, Changi Airport’s largest ground handler, has introduced augmented reality (AR) smart glasses in its ramp handling operations. The ergonomically-designed smart glass will provide SATS’ ramp handling staff with critical information, such as loading instructions, in real-time, instead of relying on paper instructions and voice-only communications. Using the wearable AR technology, operators will be able to scan visual markers found on baggage and cargo containers that provide details such as weight, unit number, loading sequence and the allocated position within the aircraft. This hands-free process improves safety, and increases the accuracy and efficiency of baggage and cargo loading. The smart glass comprises a monocular display and onboard processor with video recording features and wireless connectivity capabilities. Video streaming enhances the visibility of ramp handling operations across the airport by providing the ramp smart control centre a real-time view of on-ground processes. With the see-what-I-see feature, flight controllers within the control centre can better supervise and provide instructions to operators on how to handle cargo with special handling requirements. In addition, they would also have enhanced oversight of the loading process, which will enable greater flexibility in manpower management. According to SATS, using the smart glasses potentially shortens cargo loading time by up to 25 per cent. This would create competitive advantages for airline customers who could reduce waiting times for passengers and 08

shorten transit times for airfreight shippers. The project was developed in partnership with the Civil Aviation Authority of Singapore, which co-funded the development cost. Mr Khaw Boon Wan, Coordinating Minister for Infrastructure and Minister for Transport, who graced the launch of the smart glass, said, “This innovation will directly benefit our airport workers, raising their productivity and making their workplace safer. This is the way to tap on technology to keep our airport and airlines ahead of their competition.” To ensure successful implementation of this disruptive new technology, SATS will be introducing the smart glass in phases with full implementation expected by the middle of next year. Currently, almost 600 staff are undergoing training to use the system. The company is also investing in next-generation training aids, such as using virtual reality technology to simulate accurate on-ground scenarios within a safe and controlled environment. “With passenger demand forecast to double by 2035 to 7.2 billion air travellers, we are preparing to handle more passengers, aircraft and airfreight. SATS is embracing technology to handle these volume increases in an innovative, sustainable way. By introducing augmented reality to our ground handling operations, we are improving services for airlines, passengers and airfreight shippers,” said Mr Alex Hungate, President and Chief Executive Officer, SATS

NI TREND WATCH 2018

EXPLORES THE TRENDS DRIVING THE FUTURE National Instruments (NI) recently announced the release of NI Trend Watch 2018. The report covers the following topics: • Machine Learning Puts Data to Work - Intelligent systems create and rely on data, but the ever-increasing quantity of data exacerbates the Big Analog Data challenge. NI Trend Watch 2018 examines how machine learning addresses the problem head-on, so engineers can focus on finding and solving the next grand challenge. • 5G to Disrupt Test Processes - 5G innovation does not stop at design. Test and measurement solutions will be key in the commercialisation cycle, but 5G requires a different approach to testing, than previous wireless technologies. The report discusses what it is going to take to make 5G a reality. • Three Mandates of the IIoT - The proliferation of smart and connected ‘things’ in the Industrial Internet of Things (IIoT) provides tremendous opportunities for increased performance and

lower costs, but managing these distributed systems is often an overlooked challenge. NI Trend Watch 2018 explores the three necessities for successfully managing ‘things’. • Effects of Electrification - The vehicle electrification trend goes deeper than a global shift from internal combustion and hybrid vehicles to fully electric powertrains. The report considers implications beyond the increasingly complex vehicle itself, including new demands on supporting infrastructure. • Breaking Moore’s Law - The constant pace of innovation has tracked remarkably close to Moore’s Law for decades, despite a few minor revisions and much talk of its death. But now, the more than 50-year-old observation is facing health challenges again. NI Trend Watch 2018 explains what that means for the future of the semiconductor market.

INVESTIGATION ON HYDRODYNAMIC PERFORMANCE OF HEAVE PLATES UNDER SEMI-SUBMERSIBLE FLOATING WIND TURBINES by Dr Arun Dev, Associate Professor, Marine Technology, Newcastle University in Singapore This article presents the effects of heave plate diameter and thickness on hydrodynamic coefficients and responses. In order to reduce heaving responses in offshore structures, heave plates are commonly used and a model which will display the effects of heave plates without the interference of other supporting braces and structures was used in this research with structural properties neglected. MOSES, a potential flow theory software, from Bentley Systems, was used to estimate the added mass and damping coefficients as well as the hydrodynamic response in the time domain.

Dr Arun Dev

However, as viscous effects are neglected, the cases were simulated in Autodesk CFD, where viscous forces can be considered as a factor, and compared against published results. From this study, it was found that the Keulegan-Carpenter (KC) number has to be taken into account when deciding the thickness of plates and wave amplitude was one of the key deciding factors for determining the heave plate diameter. It was expected that the data would contribute to determining the basic dimensions for circular heave plates under semi-submersible offshore floating wind turbines. INTRODUCTION Wind is a clean, free and inexhaustible source of energy. In recent years, there has been increasing efforts to harness wind energy. Developments are moving towards deeper waters, which offers more advantages like lower noise levels and fewer size limitations. Based on current design and installation techniques for offshore drilling platforms, there are three main floating wind turbine base platform designs. Other than spar and tension leg platforms, the other popular option is the semi-submersible type wind turbine. Designs of existing semi-submersible floating wind platforms consist of three cylindrical columns arranged in a triangular format and connected by bracings, with an apex of the triangle usually facing the direction of incoming waves. Details in the design are extremely important, as extreme platform motions will affect operations and if they exceed certain limits, it may result in downtime for the wind turbine, resulting in a reduction in energy yield. Resonance occurs when the natural frequency of the platform coincides with the frequency of incident waves. This can be avoided, by either increasing the damping of the system, through inducing viscous effects from flow 26

separation and vortex shedding, or increasing the natural heave period beyond the dominant wave energy range, by adding heave plates to the bottom of the columns to increase added mass. In order to find out the hydrodynamic responses of heave plates, previous experimental and numerical studies simulated the plates within oscillatory flow or force-oscillated under still water conditions. Results are usually presented using two non-dimensional parameters, the KC number and the Reynolds number.

Re With Um as the velocity amplitude of flow, D as the diameter of column or heave plates, T as the period of oscillation and Ď&#x2026; as the kinematic viscosity of fluid. Together they can be combined to form another non-dimensional frequency parameter:

MARINE & OFFSHORE ENGINEERING

Heave plates were first investigated for use on tension leg platforms and spar platforms. Early papers such as Thiagarajan and Troesch (1994) and Magee et al (2000) investigated the addition of heave plates for tension leg platforms and showed that even in small currents, it is able to increase the damping significantly. Li et al (2013) experimented with square heave plates with three plate thickness ratios on square plates, through forced oscillation and obtained added mass and drag coefficients over a range of frequencies. Subbulakshimi et al (2015) investigated the hydrodynamic response of spar with heave plates, numerically, using WAMIT software, and found a range of diameter ratios for significant heave reduction. Sudhakar and Nallayarasu (2011), as well as Subbulakshmi and Sundaravadivelu (2016), conducted experiments on scaled down spars with heave plates attached, and the results agreed with Subbulakshimi et al (2015), over the range of diameters for optimum heave response. Tao and Cai (2003) investigated diameter ratios as well as thickness to diameter ratios numerically. The results presented the influence of geometry ratios and KC numbers on hydrodynamic coefficients, heave response and Response Amplitude Operators (RAOs). Robertson et al (2014) performed a collaborative investigation to simulate a common floating offshore semi-submersible wind turbine, to look at the differences in results and responses, under different codes. However, in the model used for the design, the heave plate diameter and thickness, of 24 m and 6 m, respectively, seem to be larger than that needed, according to previous research. To investigate the effect of heave plates on hydrodynamic coefficients, eg added mass and damping coefficients, in addition to hydrodynamic heave responses, the potential flow solver, MOSES, was used and a Computational Fluid

Dynamics (CFD) software, Autodesk CFD, was also used, in order to take into account viscous drag flow around the model, and to compare the heave response results with those from MOSES. Therefore, the aim of this work was to investigate the hydrodynamic performance of heave plates with different diameter and thickness ratios for semi-submersible floating wind turbines and see if the data can be optimised for further development and research.

MODEL SPECIFICATION The model considered for this study was based on the prototype design from NRELâ&#x20AC;&#x2122;s DeepCWind, as seen in Robertson et al (2014) and shown on the left of Figure 1. Similarly, the deck of the platform is elevated 10 m above the Still Water Level (SWL), with the draught of the platform set at 20 m. The platform used for this research, as shown on the right of Figure 1, consists of three main columns, three sets of heave plates below the columns as well as braces above the waterline to connect the columns above the waterline, to obtain accurate results for the plates and body, without the interference of other cross bracings seen on the original DeepCwind. In this research, a total of four cases, up to a diameter ratio of 1.6, were considered. In addition, three different plate thickness ratios were also investigated, with dimensions as shown in Table 1. The density of the steel used in this study was set at 7850 kg/m3 for the calculation and definition of weight and radius of gyration,within MOSES and Autodesk CFD. In this research, bending was neglected in the platform and internal stresses were not considered. For a realistic system, columns would need to be thicker and more bracing and stiffeners would have to be added to the model, however for just analysis, they were omitted from this research along with the wind turbine structure.

MOSES MOSES is a potential flow engineering tool used to predict loads on offshore structures in different sea environments. MOSES has three types of solution models, based on strip theory and diffraction theory, which take into account radiation damping but not viscous damping, and on the Morison equation which takes into account viscous drag but not radiation damping. In this study, the efforts were directed at solving for forces and responses using diffraction theory. The model would be able to capture excitation from waves and radiation, however, it would not be able to capture viscous forces. In obtaining diffraction solutions, the panelling method is one of the most common methods for modelling potential loads. In order to maximise the accuracy of the solution, the panels of the model were refined as necessary, with the recommended amount of panels around 1000. Thus, in this study, a maximum distance of 8 m was defined with the solver automatically refining the panels, as needed. A total of three sea states, as seen in Table 2, was used for testing the hydrodynamic response of the models in this section, with slightly differing wave periods and heights. Time domain analysis had to be conducted, in order to determine the hydrodynamic heaving response of the platform and thus mooring lines needed to be defined. A soft mooring line, with negligible influence on the platform, was used, in order to get the full damping of motion from the heave plates without interference from pre-tensioning of mooring lines.

RESULTS Added mass and damping coefficients Based on Sarpkaya (2010), an estimation of added mass coefficients and natural period of the cases is shown in Table 3. Figures 2 and 3 show the added mass and damping coefficients, computed using MOSES. Higher added mass coefficients are reflected for Cases 2 to 7 with heave plates, which are expected. However, for Case 1, the added mass coefficients from MOSES are larger than estimated, even though there are no heave plates attached. As the added mass coefficients are computed by MOSES, based on DNV-RP-C205, the values expected should not differ much from the estimated values. For the different thicknesses investigated, they were also expected to have similar and higher added mass coefficients, according to what Li et al (2013) reported, where thickness has little influence on added mass of the plates other than at higher KC numbers. On the other hand, the thicknesses used for this study were larger compared to the plates Li et al (2013) experimented with. Therefore, a slightly larger difference in added mass is seen. As seen in both added mass and damping coefficients, around a period of 13, the values may show a bit of fluctuation due to the encountering frequency being near the natural frequency of the cases. For some cases, it seems the fluctuation in values occurs at points that are different from those expected, which could be attributed to an error in the panelling of the model during solving.

from the trend, Case 4 should no longer have the worst response as the range of thicknesses with lower damping is now affecting smaller aspect ratios, and the expected aspect ratio that will result in lowest damping should be around 0.05. As shown in Figure 4, Case 3 did show signs of higher heave responses with Case 2 still the best and Case 4 having slightly better responses.

Figure 2: Added mass coefficient

The results from the three different thicknesses showed the same trend, with the thinnest plate at 0.33 m showing the least amount of heave over the period of 1000s, which agrees with Tao and Cai (2003), where they reported that a minimum thickness should be chosen in order to maximise damping. However, all three cases did not seem to have the exact same results as the published results and this could be due to viscous effects not being a factor in MOSES.

Diameter Ratios At a low KC number, responses from different diameter ratios are not expected to show large variation, as compared to those for higher KC numbers. Nonetheless, from the results of Tao and Cai (2003), a damping ratio of 1.6 was expected, to reduce the heave response by half, as shown in Figures 7 and 8.

Figure 3: Linear damping coefficient

From Figure 3, a higher diameter ratio gives a higher damping ratio, as shown by Cases 6 and 7. Tao and Cai (2003) similarly reported that larger diameter and thinner plates generally gave higher damping. Case 2 also showed higher damping coefficients compared to Cases 3 and 4.

Aspect Ratios According to the results of Tao and Cai (2003), there is lower damping expected for a range of aspect ratios, from 0.1 to 0.16, due to the forces of viscosity and convection cancelling out each other for a KC of 1.0, and damping will begin to increase once the aspect ratio is reduced. Even though MOSES is unable to account for viscous damping as water is assumed to be inviscid, the hydrodynamic response results for Sea State 3 in Figure 6 agreed with the studies where Case 4 showed the worst heave response of the three and Case 2 showed the best.

On the other hand, at a higher KC number, near 1.0, a diameter ratio of 1.6 should significantly show better heave response when compared to that for smaller diameter ratios. Despite that, Case 7 actually showed the worst heave responses in Sea State 3, with Case 2 showing the best. Probably, owing to the fact that viscous damping was not a factor in this solver, the results of Figure 9 did not accurately portray the results from Tao and Cai (2003). This shows that heave plates, subjected to different wave conditions and KC numbers, would show different responses. The results reflected the computed data through the use of potential flow theory software which matched the studies to a certain extent. However, as the software is unable to take into account all hydrodynamic forces on the model and damping resulting from viscous effects, it is important to simulate the cases within Autodesk CFD, when viscous damping becomes another factor, as radiation damping accounts for a very small percentage of damping.

For Sea State 2, where the KC number is about 0.75, Tao and Thiagarajan (2003) obtained results similar to those of Tao and Cai (2003) and showed that the range of aspect ratios that results in lower damping corresponds to a KC of 1.0. Figure 5 also showed similar inclinations as Figure 6 where Cases 3 and 4 have the worst performing heave plates and Case 2 has the thickness with the best heave response. As for Sea State 1, which corresponds to a KC number of 0.345, previous studies showed results only at lower or higher KC numbers. However, looking at the results of Tao and Cai (2003) and Tao and Thiagarajan (2003),

AUTODESK CFD For this study, Autodesk CFD was used for easier modelling of geometries and to account for the viscous drag.

SETTING UP SIMULATION DOMAIN

Figure 5: Heave response of plates in Sea State 2

The 1:80 prototype is scaled down from the dimensions used in MOSES, as Autodesk CFD is not able to mesh the model and domain for accurate results within a reasonable amount of time. In Figure 10, air and water domains are modelled with the prototype a distance away from the inlet and outlet, with the scaled down depth of the water domain equivalent to a water depth of 200 m. Since the prototype and domains are scaled down, the sea states used for simulations also have to be scaled down accordingly and are shown in Table 4.

Table 4: Scaled down sea states for simulation

An inlet velocity is pre-defined and boundary conditions with pressure equal to zero are defined at the outlets and where there would be atmospheric pressure. Sides with no boundary conditions applied were assumed to feature no-slip conditions. To prevent backflow of water unable to exit the domain, an outlet velocity is defined at the air outlet and for this study, a velocity of 0.0005 m/s was used to prevent too much water from exiting the domain. Figure 8: Heave response of plates in Sea State 2

As Autodesk CFD does not allow the mixing of liquids, the air domain is also defined with water as the medium. As an initial condition, the height of fluid is defined for the water domain, at the beginning of the simulation. To understand the hydrodynamic heave response for the different cases, the model is constrained, so that it moves only vertically, that is, in the Z-direction.

In Sea State 2, Case 3 showed the smallest heave response in comparison to Cases 2 and 4 which showed

MARINE & OFFSHORE ENGINEERING

larger heave responses, with sudden increases and decreases in heaving. As the KC number for this sea state is quite close to the KC number of 0.075 investigated by Tao and Thiagarajan (2003), a similar trend in the results was shown. As the thickness ratio reduces, the damping ratio starts to increase and within a range of thickness ratios, between 0.024 and 0.036, significantly lower damping ratios were seen, probably due to the forces of viscosity and convection cancelling each other, resulting in the decrease in damping. As the thickness ratio starts to get even smaller, the damping ratio increases sharply again. Therefore, Case 2, with a thickness ratio of 0.025, is expected to perform the worst and Case 3 is expected to perform the best, before the drop in damping is expected. From Figure 12, it can be seen that the results are exactly as Tao and Thiagarajan (2003)

reported. However, for Sea State 1 in Figure 11, given the KC number is close to that of Sea State 2, a higher heave response was seen in Case 3 which was supposed to give the best heave response. In Sea State 3, as the KC number increases, the range of thickness ratios, where damping is affected by the forces of viscosity and convection cancelling each other, gets wider and affects larger thickness ratios. From the results of Tao and Thiagarajan (2003) and Tao and Cai (2003), looking at the trend in both results, Case 3 should be around the range where the lowest damping is expected. From Figure 13, Case 3 did match the results predicted, with Cases 2 and 4 having a slightly larger heave response.

Diameter Ratios In Sea State 1, which is shown in Figure 14, all cases showed rather similar heave responses. A few cases showed fluctuations, with sudden increases and decreases every few seconds. In comparison with the results of Tao and Cai (2003), even at a low KC number, a response should be expected from a higher diameter ratio and Case 7 was expected to have the best heave response. Yet, Case 7 showed the largest fluctuations in heave response, occurring every few seconds, while the other three showed similar heave responses with smaller fluctuations.

Figure 11: Heave response of plates in Sea State 1

Similarly, in Sea State 2, the best heave response was again expected from Case 7, and from Figure 15, the results reflected this exactly. The results for Case 5 were also comparable, while those for Case 2 were the worst. In Sea State 3, at a higher KC number, there should be a large difference in damping for the different cases, as shown by Tao and Cai (2003). Even though Case 7 did show the best heave response out of the four cases, towards the end of the graph, responses of all four graphs did not vary significantly.

Figure 12: Heave response of plates in Sea State 2

Figure 13: Heave response of plates in Sea State 3

Tao and Cai (2003) reported that using a heave plate diameter extension, around four times the heaving amplitude, would roughly give the best heave response for the particular condition. From the results of the three sea states, it can be seen that the plate diameter performance for a particular sea state is comparable to that expected for large plate diameters.

MARINE & OFFSHORE ENGINEERING

Figure 15: Heave response of plates in Sea State 2

From the results on diameter ratios, from MOSES, both Sea States 1 and 2 showed results, in accordance with those of Tao and Cai (2003), indicating that a larger diameter should show a smaller heave response, by around half, for a diameter ratio of 1.2. Sea State 2 surprisingly showed that Case 7 performed the worst when it should have been one of the better-performing diameters. However, based on the fact that Tao and Cai (2003) also reported that a plate diameter should be chosen, that is four times the wave amplitude, all three sea states did not show the results, with MOSES. On the other hand, the results from Autodesk CFD, which has viscous forces as a factor, reflected the findings quite accurately, with Sea State 1 showing smaller plates performing better and Sea State 3 showing larger plate diameters performing better. Potential flow theory portrayed accurately that higher diameters do provide better responses, however, only Autodesk CFD reflected the results of Tao and Cai (2003), where for a heave plate, with a diameter extension of four times the heaving amplitude, the hydrodynamic response is comparable to better responses of larger heave plate diameters.

Figure 16: Heave response of plates in sea state 3

DISCUSSION The results from MOSES and Autodesk CFD cannot be directly compared, due to the fact that the Autodesk CFD results were obtained from a scaled down simulation. For the results of aspect ratios in MOSES, as there were no exactly similar results that could be used for comparison, for Sea State 1, by looking at the trend, the results were comparable to what was expected for that KC number, from the results of Tao and Cai (2003) and Tao and Thiagarajan (2003). Sea States 2 and 3 showed similar results to those reported by Tao and Cai (2003) and Tao and Thiagarajan (2003). In Autodesk CFD, the KC numbers used were much smaller, due to the scaled down sea conditions. Sea States 1 and 2 had the lowest KC numbers which were compared to the results of Tao and Thiagarajan (2003). Sea State 2 shows the exact same result as predicted, however, Sea State 1 showed Case 2 having a worse response than Case 3 which was expected to have the worst response. Since Sea State 3 was also at a KC number not previously investigated by the two authors, similar to the results from MOSES, by looking at the trends for other KC numbers, they matched the prediction quite accurately. At a low KC number, the results using MOSES and from Autodesk CFD agree with the results of Tao and Thiagarajan (2003) and Tao and Cai (2003), with regard to the aspect ratio. However, since only one higher KC number is covered in this study, further investigation has to be done to validate the results of previous research. 32

THE SINGAPORE ENGINEER October 2017

Since MOSES is a potential flow theory solver, the hydrodynamic response will not be as accurate, since the viscous effects are not taken into account. However, the added mass did not seem to have an effect, as expected, which could have been a result of panelling errors. The response of the models may have been affected, as a result. As Autodesk CFD is not used for evaluating the response of offshore structures in water, it is unable to produce results of hydrodynamic coefficients and RAOs. As it is unable to take into account how buoyant the structure is in water, and it is not possible to specify the centre of gravity and buoyancy in the software, the results may not be accurately presented. One of the main factors that influenced the results of this research was the water level in the domain. As Autodesk CFD is unable to apply absorbing boundary conditions, as investigated by Luppes et al (2010), there may be a backflow due to the water being unable to leave the domain and flooding the air domain, as shown by the image at the bottom of Figure 17, unless physically applying an outlet flow. For this study, a velocity of 0.0005 m/sec was used at the air outlet to remove any water stuck around the outlet. However, the velocity used is just a simple way to get the water out, which may have an unimaginable impact on the entire simulation. The velocity used was seen to give a reasonable response for Case 7, as seen in Figure 18. One of the results of the outlet velocity is the reduction of water in the domain, as seen in Figure 19. This would have resulted in a certain degree of inaccuracy in the results, as the water level would not be constant throughout the entire simulation.

MARINE & OFFSHORE ENGINEERING

• The effect of scale factors on the results from AutodeskCFD has to be further investigated. • Depending on the KC number, the range of thicknesses, where lower damping is experienced, has to be avoided, to minimise heave responses. • Even with a range of optimum diameter ratios, from 1.2 to 1.6, heave plate diameters for different platforms should be designed, based on the common operating conditions nearby. Using a heave plate with four times the wave amplitude is generally found to minimise damping, that could only have been achieved at larger diameters.

CONCLUSION A series of heave plates, with varying diameters and thicknesses, were investigated numerically and presented with their hydrodynamic coefficients and responses. Based on MOSES and Autodesk CFD, the following conclusions were formed. • Autodesk CFD could be a potential software to simulate offshore structures, if the extraction of the centre of gravity,buoyancy as well as hydrodynamic data and coefficients are possible. • Investigations have to be conducted in Autodesk CFD, on larger KC numbers for various plate thickness ratios.

DIGITALISATION OFFERS

MULTIPLE BENEFITS ABB’s digital portfolio for the maritime industry facilitates seamless exchange of data as well as integration of sensors, automation, and ship software and cloud solutions. Fleet Intelligence ABB has added ‘Fleet Intelligence’ to its ABB Ability Collaborative Operations software, providing marine customers with a single and complete overview of their ship system maintenance needs. ABB Ability Fleet Intelligence addresses a common shortcoming in ship efficiency, where data from manufacturer manuals provide the basis for the planned maintenance system, which means that equipment is maintained to standards set by vendors rather than being based on the needs of customers. Delivering greater efficiency and more precise inspection scheduling, as well as better spare parts availability, asset protection and prolonged equipment service life, Fleet Intelligence minimises the requirement for service engineer visits, resulting in lower costs. It combines cutting-edge IT for marine equipment maintenance planning, including advanced analytics of data in the cloud, with ABB’s domain knowledge and technical services support from remote operational centres. According to ABB, many of the marine maintenance solutions that have emerged are unable to exchange data seamlessly. The company says that, typically, the condition monitoring systems are not based on specific failure modes and services are delivered by multiple providers. Data-driven services use different delivery methods, while stand-alone web applications and reports make it difficult for operators to get a full overview of their actual maintenance needs and plan for them. Building upon ABB’s Asset Health Center (AHC) software, which is already used within several industries, the Fleet Intelligence module harnesses the integration at the heart of shipboard ABB Ability systems, such as Integrated Automation and Remote Diagnostics. Furthermore, the system is also able to collect data from third party applications. When developing this solution, ABB looked at how the airline industry digitalised its maintenance strategy. Assessing maintenance activities, using a Reliability Centered Maintenance (RCM) approach, and creating a Failure-Mode, Effects and Criticality Analysis (FMECA), allowed ABB to focus on optimising maintenance by identifying and reducing the risk to the assets onboard a ship. 34

Fleet Intelligence provides a complete overview of the ship system maintenance needs.

Fleet Intelligence software incorporates equipment condition monitoring, including analysis and visualisation of defined performance parameters. In addition, condition monitoring can be supported by remote diagnostics services, including preventive maintenance recommendations or even predictive edge analytics. In this way, customers who already make use of ABB’s remote diagnostics offering, are now able to fully close the loop when it comes to smart vessel maintenance, lifecycle management and protection of their assets. The ABB Ability AHC is software specifically designed to create a collaborative environment for the vessel and the onshore support organisation, whilst also enabling machine learning. ABB believes that the marine industry’s OEMs, service providers, classification societies and vessel owners will ultimately combine data from multiple cloud solutions through standard or application-specific APIs, defined as inter-cloud communication.

ABB Ability Collaborative Operation Centers ABB has opened a new ABB Ability Collaborative Operations Center in Florida, USA. The centre will remotely monitor ships around the globe and will work in conjunction with similar facilities in Europe and Asia. The centres (formerly known as Integrated Operations Centers) monitor data sent by vessels, allowing the company to work with customers in the event of equipment failure or on routine maintenance.

MARINE & OFFSHORE ENGINEERING

ABB is also opening a Collaborative Operations Center in Genoa, Italy, which will have an emphasis on automation systems as well as its regular duties to customers.

Operations Center turn red and engineers immediately start to resolve the issue.

The company is already remotely monitoring more than 700 ships and aims to raise that number to 3 000, by 2020. The two new centres are now part of a roster of Collaborative Operation Centers, that includes Singapore, Billingstad (Norway), Helsinki (Finland), Västerås (Sweden), San Diego (USA) and Dalfsen (Netherlands) - all of which are dedicated to shipping.

Remote Diagnostic Services

As the centres are located in different time zones, they are able to support customers in the marine and ports industry, round-the clock. Experts will be available during their daytime working hours, at a Collaborative Operations Center, to immediately respond to the needs of ship owners and operators. ABB also provides real-time support for operating vessels, with the company’s software combining weather forecasts with vessel and load data, to assist captains in plotting the ideal course. The Collaborative Operations Centers collate data that can then be shared on a common platform with customers, to troubleshoot problems. When a critical alarm is triggered onboard a vessel, the lights in the Collaborative

ABB has deepened its analytical and predictive approach to vessel maintenance with the latest upgrade of its Remote Diagnostic Services (RDS). The company is aiding the development of shore-side operations of shipping companies by giving the opportunity to replicate ABB’s Collaborative Operations Center in their own Operational Centres. The latest version of the RDS software allows shipping companies to deploy their own analytics, or those from a third party, where applicable, with greater ease. ABB has further developed its dedicated hardware for the monitoring of large and small rotating machinery with tight integration to the RDS software. The graphical user interface has also been improved to increase user experience and to give identical views of the detailed data both onboard and onshore. To further leverage the data received from vessels, the ABB Digital Service team has been strengthened with more data scientists and architects to promote the search for insight into the health of the monitored assets. The ABB software used as part of the RDS combines the capabilities of a dedicated onboard software with a full analytic engine onshore. Due to this modularity and capability, the software can now run the same analytics onboard a ship as well as onshore. For shipping companies with limited bandwidth availability or a high number of data points, ABB is deploying leading edge analytics to seamlessly customise the solution and optimise the data transfer.

A Collaborative Operations Center can remotely monitor ships around the globe.

An internal study found that by taking a proactive approach to the monitoring of equipment through the use of RDS and its software, customers were able to save up to 50% on maintenance costs. There has also been up to a 70% reduction in visits by ABB engineers to vessels, bringing a significant decrease in the cost for customers.

ITE TEAM DEVELOPS SUPERIOR METHOD TO REMOVE KIDNEY STONES Partnership between ITE, NUH, NUS and Invivo Medical seeks to bring innovation to market. A team comprising staff from ITE has successfully created a solution to simplify percutaneous-nephrolithotomy (PCNL) which is a complicated process of removing large or complex kidney stones. PCNL is usually carried out by senior surgeons. Traditionally, PCNL surgeons refer to x-ray imaging of the patient’s kidney to locate the stone(s), before inserting a long and hollow needle through the skin to reach the stone(s). Through the needle passage, an endoscope is then inserted and through it, a surgical instrument is manipulated to fragment and remove the stone(s). This is complex, as the surgeon has to use free-hand techniques to locate the stone(s) in a three-dimensional environment, while referring to a two-dimensional image. At times, several attempts may be required, which lengthens the patient’s exposure to x-ray radiation and the recovery period.

Complex procedure made simpler and safer The development of the Percutaneous-Access-to-Kidney-Assist Device (PAKAD) has been made possible through ITE’s collaboration with the National University Hospital (NUH), the National University of Singapore (NUS) and Invivo Medical Pte Ltd. The PAKAD incorporates precision engineering mechanisms to systematically adjust, guide and stabilise the needle into alignment with the targeted stone(s). Through successful trials on animals at NUH, the PAKAD has proven that it can simplify and shorten the PCNL process, hence reducing x-ray exposure, risks of complication, and recovery periods. With the PAKAD, junior surgeons can also perform the needle insertion procedure.

Multiple parties make innovation possible The ITE team’s research efforts were strengthened through the domain expertise of NUH and NUS. Through Invivo Medical, the device will be commercialised, and a licensing agreement was signed among ITE, NUH, NUS and Invivo Medical. The team received financial support for the applied research, through the MOE Innovation Fund, the NRF Proof-of-Concept grant, and the MOE Translational R&D and Innovation Fund. Work on the PAKAD started in 2011. After it was developed and a patent application was filed, the PAKAD was first showcased at a major event at TechInnovation 2013, as part of the Singapore start-up ecosystem. At the event, PAKAD was matched with an investor, Invivo Medical, who is now bringing the device to market. The PAKAD is expected to reach the market by the end of 2018 and sales of the device could reach SGD 25 million over the next five years. “This is an excellent example of industry-institution partner40

ship to develop innovative and integrated solutions to improve productivity and processes. We are grateful to NUH, NUS and Invivo Medical, to enable ITE to create and patent the Percutaneous Access to Kidney Assist Device (PAKAD) for safe kidney surgery”, said Ms Low Khah Gek, CEO, ITE. “The new technology allows for better precision during surgery and enhances patient safety and outcome. It expands on NUH’s track record of partnerships for clinical innovation and development that help raise the standard of clinical care. We look forward to more of these collaborations to bring about greater tangible benefits for our patients”, said Prof Kesavan Esuvaranathan, Head and Senior Consultant, Department of Urology, National University Hospital. “NUS is delighted to have been part of this multi-party collaboration. Researchers from the NUS Yong Loo Lin School of Medicine provided medical expertise, which ITE used to enhance the PAKAD. Realising the strong potential for this technology to improve clinical procedures and healthcare for kidney stone patients, the NUS Industry Liaison Office took the lead in the commercialisation process, including managing negotiations for this multi-party licensing agreement. Our endeavour to bring innovative technologies closer to market is made possible with great partners who have similar goals”, said Mr Sean Flanigan, Director, NUS Industry Liaison Office. “The new medical-device is the world’s first operational Percutaneous Access to Kidney Assist Device (PAKAD). It is the result of a successful collaboration by three institutions and the industry, and made possible by a match-up at TechInnovation 2013. Beyond this, we plan to do continual product development to apply the invention to more minimally-invasive surgical and biopsy procedures”, said Dr Joseph Chai, Managing Director / Director, Invivo Medical Pte Ltd.

FUTURE MANUFACTURING

ENERGY EFFICIENCY GAINS ACHIEVED IN AUTOMOTIVE PRODUCTION PLANT At the BWM Group’s engine plant in Steyr, Austria, in a reference project validated by the Technical University of Vienna, Ecoclean Monschau has significantly raised the energy efficiency of a flexible EcoCFlex Classic robot cell that had been in service for several years. The system’s electric power and water consumption were each cut by around 30%. These energy efficiency measures are now expected to be implemented in another 95 systems of the same type installed at various sites throughout Europe and Asia. The BMW Group has been using EcoCFlex Classic robot cells made by Ecoclean Monschau for around 12 years, in several of their factories, to debur and clean engine parts such as cylinder heads for diverse car models. At the Steyr engine plant, 30 first-generation units of this flexible cleaning machine are in use. Now, as before, their cleaning performance is beyond reproach. However, in terms of energy efficiency - a parameter closely monitored by the BMW Group - the systems are no longer up to today’s standards. Their water consumption, in particular, has proved to be too high. BMW Steyr therefore contacted the equipment manufacturer, enquiring if and how the machines could be optimised in terms of energy performance.

Analysis reveals options for savings Ecoclean has developed a method of analysis, especially for this type of task. In their investigation, the equipment maker’s service staff focused on factors such as the water consumption, cleaning agent input, electricity demand of power drawing equipment, and the consumption of compressed air. Flow measurements revealed that large quantities of vapour were extracted from the cleaning cell, causing the machine’s elevated water consumption. Furthermore, the analysis identified major electricity-saving potential in the operation of the feed pumps.

Large benefits from small measures One measure taken to reduce the water consumption involved changes on the air control dampers. Moreover, 44

the flow velocities inside the system were adapted via a modified fan control regime, resulting in substantially less vapour getting discharged. In the case of the booster pump, a variable-frequency drive unit now provides demand-based control and hence, energy savings. Thanks to these relatively minor improvement measures the system’s overall electric power consumption was cut by around 30%. Savings of the same magnitude were achieved in the area of water consumption, which in turn means a reduced need for cleaning chemicals.

Independently validated reference project The measures were initially carried out on a system installed in the engine plant in Steyr, Austria. For an objective evaluation of results, the Technical University of Vienna validated the reference project with extensive pre- and post-optimisation measurements.

EDUCATING MEMBERS ON THE INS AND OUTS OF PROPERTY LOANS Another edition of the bi-monthly IES Members’ Night took place on 15 August 2017, at the training rooms located at our Bukit Tinggi premises. Titled “Choosing the Best Property Loans and the Best Way to Protect Them”, it was delivered by an expert from IPP Financial Advisers (IPP), who also kindly sponsored dinner for the evening, which began before the talk at 6.30pm. Many members agreed that having a dinner session before the talk was a good opportunity to know other members and to connect with fellow engineers. IES Honorary Secretary, Er. Joseph Goh, kicked off the event with his opening address. He shared that IES Membership team had been working hard to improve services members, who can expect to enjoy more value-added benefits such as more workshops, networking sessions and merchant benefits in time to come.

Thereafter, guest speaker Yeo Wee Khin, Senior Advisory Group Partner of IPP, shared his insights on the unique merits and disadvantages of home loans taken from banks versus that from the HDB. With 31-years of financial industry experience, Mr Yeo is an industry veteran. He delved into the types of different bank home loans, including fixed and variable-rate loans, and covered interest rates such as SIBOR-dependent rates and fixed deposit home rates. He demonstrated how small differences in housing loan interest rates may appear insignificant, but can translate into thousands of dollars of savings in the long-term.

Mr Yeo explaining to members about the nuances of mortgage insurance

For example, a HDB loan can be ideal for risk-adverse Singaporeans who prefer to pay less down-payment. But for more savvy borrowers, the right bank loan can offer substantial cost savings. He also covered mortgage insurance, which is vital for protecting homes and the loans taken out for them. Whether level or reducing, it enables one to keep their dream home and maintain his or her family’s lifestyle in the event of death, disability or disease. Looking at mortgage insurance plans from different companies, Mr Yeo highlighted the importance of comparison, as premiums can differ significantly with the same mortgage cover. With such a well-received talk, it is certain that we will be inviting him for future Members’ Nights. As always, we would like to thank all members for your support and hope to see you at future events!

BUILDING CROSS-BORDER

FRIENDSHIPS WITH HEART AND SOLE On 20 August 2017, The Institution of Engineers Malaysia (IEM) held their annual run at the Perdana Botanical Gardens in Kuala Kumpur. IES, at the invitation of the IEM Young Engineers Section (YES), sponsored three members to participate in the event. Registering themselves for the 5 km women’s open category run were Er. Emily Tan [Founding Chair of the Women in Science, Engineering and Research (WiSER) Committee], Ms Jasmine Foo (WiSER Chairperson for 2017/2018) and Ms Esther Neo (WiSER member). More than 1,000 participants turned up at 7 am at the Perdana Botanicial Gardens for the warm up. The 10 km men’s and women’s run was flagged off at 7.30 am, followed by the 5 km runners at 7.45 am. The route, which took runners around the various parts of the gardens, was a pleasant one. Perdana Botanical Gardens, which occupies an area of about 91 hectares, is Kuala Lumpur’s first large scale recreational park and is situated within the hilly heritage park of the Malaysian capital.

She received her trophy from IEM President Ir. Tan Yean Chin. The first place went to an international runner from Japan. The run was a good chance to meet and network with fellow like-minded engineers from the region in a casual setting. It was, at the same time, opportune to further cement the longstanding relationship and goodwill between the two neighbouring engineering institutions. Apart from Er. Tan, Ms Foo and Ms Neo, there were others who hailed from all over Malaysia including Penang, Pahang and Miri. Just the night before, IEM-YES hosted a welcome dinner for all runners at the Coliseum Café & Grill Room in KL. IES’ participation was acknowledged during the welcome speech made by the organising chairperson for the run, who also welcomed IES’ participation in similar future events. All three participants would like to thank IES for the opportunity to represent Singaporean engineers in the IEM Run 2017.

It consists of several themed gardens, including a Hibiscus Garden that showcases different species of Malaysia’s national flower. Ms Neo, an active participant in the IES Women’s Netball team for the past two years, did IES proud by coming in second in the Women’s 5km Open (Veteran) Category.

VIEWPOINT

DIGITALISING HUMAN CAPITAL CORNERSTONE OF SMART NATION Michael Haberzettl, Head of Human Resources, ASEAN, Siemens

Singapore’s top priority for its Smart Nation initiative has always been around jobs - job creation and better quality jobs. While urban infrastructure is critical for a digitalised nation, a truly Smart Nation cannot be built without first digitalising our talent. Smart Nation talent gaps However, we are seeing a shortage of digital specialists especially in areas like cybersecurity, data analysis, software development, user interface/user experience and network engineering. According to industry players, schools here have not been releasing enough IT graduates and sometimes they are equipped with skills that are no longer relevant. Beyond skills itself, a digitalised mindset is also critical. It comprises the ability to foresee and transform before the need to change arises; the power to stay with ambiguity and change course as you explore and experiment; and identifying opportunities for collaboration. Digitalising our talent There are two ways companies can think about digital transformation - convert their current business model from offline to online, or recondition their whole business model based on technology. The first approach is achievable in a shorter period and will likely reap immediate results. However, looking at the rapid, disruptive nature of technology, this approach only plugs a prevailing gap which will not be sustainable in the long-term. The second approach of infusing technology into the inner workings of a business enables operational agility and adaptability, allowing for more continued business growth. To stay relevant, businesses need to approach digital transformation not as keeping up with today’s needs but as anticipating the needs of the future. A large part of this is dependent on equipping today’s and tomorrow’s workforce with the right digital and problem-solving skills. Companies must adopt a more holistic approach to digitalising talent. That includes structuring the company’s business model based on technology with more cross-divisional work to share and reapply digital knowledge, and hiring the right talent. Companies must elevate the digital skills of their workforce by investing in either on-the-job training or dedicated training. Employees too, should identify industry demands and their skills development needs. Lifelong learning is crucial but educational institutes need to also ensure that they are in tune with industry demands through cross-functional learning. There must also be closer collaboration between tertiary institutes and companies. Most importantly, companies need to align their digitalisation agenda with that of the Government, in order to synergise with Government funding and schemes. Digitalisation is a way of life. It is the opportunity to deliver more value to society and, in turn, create more profitable and successful companies.
