ments required to increase this to 100 a year. TURBOMACHINERY represents the third key component of MAN Diesel & Turbo’s operations in India. At its site in Vadodara, in the Western state of Gujarat, over 100 employees provide sales, support and project management services for the company’s turbo product installations at oil refineries and steel manufacturing plants. Key clients include giant manufacturing organizations such as Reliance Industries Limited, the Steel Authority of India, and Jindal Steel and Power. Here, too, significant new investment has recently been made through the acquisition of MaxWatt, a small but successful Bangalore-based producer of steam turbines for power plants and mechanical drive applications. Peter Küper, Vice President Steam Turbines at MAN Diesel & Turbo, explains the rationale behind the deal: “MaxWatt had a product range that complemented ours almost perfectly. There was hardly any overlap, and this is what made it so attractive. Additionally, the production site in Bangalore has spare capacity and room to expand. This will be important as we see big growth potential for the future.” Emmanuel Ferdinand, Managing Director of MAN Diesel & Turbo’s India operations, adds: "With this acquisition, we continue to shape the footprint of MAN‘s Indian operations as the company‘s hub for smaller-sized machines."

he giant, 400-meter-long CSCL Globe had to first pit its 184,000 tons of steel against
an angry North Sea storm before it arrived, a day late, on 13 January 2014 on its 70-day
maiden voyage from China to Europe. Then, watched by curious onlookers, it was maneuvered down the Elbe River into its berth at the Eurogate Container Terminal – an operation that required precision work from the Hamburg Port Authority (HPA). The ship was too wide to allow two-way traffic down the Elbe River. It also could not sail fully loaded, due to the depth of the Elbe. To cope, the HPA reported that it prepared for the ship’s arrival through simulations 17 times. The CSCL Globe, built by Hyundai Heavy Industries for China Shipping Container Lines, is one of the largest container ships ever to be built. The size of four soccer fields, it can carry up to 19,100 containers – space for 156 million pairs of shoes or 900 million tins of baked beans, as the media speculated.

eye for precision and flexibility. Few places know this better than the MAN PrimeServ Competence Center Repair in Oberhausen. Here, a team of highly skilled experts and engineers are working hard to take laser cladding technology to the next level. Laser cladding describes a welding repair method in which a precision laser is used for maintenance and repair of rotors, impellers and blades suffering from wear and corrosion. The technology was implemented in 2010 and replaced the traditional method of thermal spraying. Damaged parts can be pre-diagnosed remotely using 3D scanning and are then shipped to Oberhausen for treatment. Already, more than 200 rotors and their parts have been repaired using the new method. Orders are continuously coming in f rom plants in Zur ich, Berlin and Hamburg, and a further rollout is in the plans for plants in China, South Africa and Brazil. Here, too, MAN PrimeServ technology and know-how will be put to use.
Thanks to investments in equipment and manpower, the plant in Oberhausen now has a unique market position.

For customers worldwide, MAN PrimeServ offers standardized maintenance contracts that include online monitoring, delivery of replacement parts, and on-site servicing. MAN Magazine joins a service engineer on an assignment in Sumatra.
A
September day starts humid in Medan, Indonesia. Power plant operator Berkat Bima Sentana
(BBS) has sent a driver to pick up Andreas Donderer, a maintenance engineer with MAN PrimeServ, at the hotel at 7 a.m. The drive will take an hour, on roads jammed with spluttering motorcycles and bright yellow minivan taxis, accompanied by the cacophony of blaring car horns. It’s 25 kilometers to the new
BBS power plant in the port city of Belawan. “For other assignments, accommodation is usually closer to the power plant. However, this site is so remote that there are no hotels close by,” explains Donderer, just in from Augsburg. “That’s why we have to make the trip from Medan every morning during this two-week misson.” A resident of Bavaria, Germany, and a third-generation MAN employee, Donderer loves his work. He travels most of the year on assignments to customer locations around the world, including Spain, the Dominican Republic and now Sumatra. When he is not traveling, he oversees service contracts from the MAN PrimeServ head office in Augsburg. “I am the first contact person customers reach out to, and I’m the one who goes to the power plants to carry out the maintenance work and warranty services agreed on in the contract, together with the operators,” he explains.

endowed with fossil fuels and renewable resources, these are not evenly distributed, creating windfall profits for some countries and exacerbating the crisis in others.” NIGER, IN WEST AFRICA, is an excellent example of the current African market. The landlocked nation is a large global uranium producer and began producing crude oil in 2011; but it suffers from power outages almost daily. It has to import 62% of its electricity from Nigeria and currently has an installed capacity of about just 90 MW.

easuring almost 300 meters from the sea bed to its highest point
above the surface of the North Sea, the Brent Delta oil and gas production platform is as tall as the Eiffel Tower – for the time being. Next year that will change, when, after around 40 years of operations, the structure will be decommissioned. Normally, this would mean disassembling the topside, which includes the drilling rig, helipad and accommodation block, and shipping it back to shore in smaller pieces for re-use, recycling or disposal as permitted. This time, however, the entire 24,200-metricton topside structure will be removed in a single lift operation. Only one ship in the world can do this: The MAN-powered Pioneering Spirit, built for the Swiss-based Allseas and boasting the length of about five jumbo jets. “In my 18 years at MAN, I’ve never seen anything like it,” says Wolfgang Dullinger, from the Order Management in MAN Diesel & Turbo’s Four-Stroke Marine department. PIONEERING SPIRIT is fitted with eight
MAN 20V 32/44 generator sets and one 9L 32/44 engine. Because of the demanding tasks, the vessel had a long list of requirements, with power and reliability paramount. “When you’re moving loads up to 48,000 metric tons, as the Pioneering Spirit can, engine failure would be disastrous,” says Dullinger.
“MAN’s history of delivering state-of-theart technology convinced Allseas to select them to supply the engines that power the 'Pioneering Spirit,'" says Martin Dubbeldam, Technical Superintendent at Allseas. “The flexible operating range makes them perfect for this application.” When working as a pipelayer, the Pioneering Spirit accelerates and slows every few minutes as it finishes each pipe in position-keeping mode and then moves 24 meters to lay the next piece. Of course, for the customer, the faster it can do this, the better. “This is why, despite the power demands, Allseas decided on engines with smaller cylinder-bore diameters, as they can

go from zero to full load quicker. Our 20V 32/44 engines fit the bill perfectly, and with our common rail technology, we can improve the load response even further compared to conventional injection systems,” says Dullinger. Instead of having one fuel pump per cylinder, a single high-pressure pump feeds a storage rail, which regulates precisely how much fuel is injected into each cylinder. THE SAME TECHNOLOGY is on board the Ceona Amazon, a brand new deep-water hybrid vessel with two 9L32/44CR as well as four 8L21/44CR main gensets from MAN Diesel & Turbo. The vessel can lay rigid and flexible pipelines, and can also install large, subsea structures down to 3,000 meters in depth using its two cranes. “It’s not easy to find the right engine configuration with multi-role vessels like this,” explains Rasmus Hedemark, Manager Offshore Sales for Medium Speed engines at MAN. “We need to know roughly how often it will be performing each task and where it might be operating. The 'Ceona Amazon' will be heading to some remote and challenging locations.”

Pipelayer and construction ship: MAN Diesel & Turbo has equipped the versatile Ceona Amazon.
MAN Diesel & Turbo’s 48/60 engines are a popular choice for dredging vessels, like Jan De Nul’s trailing suction hopper-dredger Leiv Eiriksson and its sister ship Cristobal Colon, the two largest such dredgers in the world. They perform two main tasks: Maintenance dredging, which is the cleaning of harbors and rivers, and land reclamation, which involves building up artificial islands, such as those that make up Dubai’s Palm Islands or Hong Kong’s international airport. The Leiv Eiriksson is fitted with two MAN 16V48/60B diesel engines, which provide propulsion power and the two suction pipes that allow the vessel to dredge sand and rocks up to a depth of 142 meters, plus the discharging pumps that empty the hopper. “Like other special-purpose ships, the vessels subject their engines to permanent and high load fluctuations while dredging, as well as a lot of engaging and disengaging of the propeller and pump clutches,” says Udo Ziegler, Senior Sales Manager at MAN Diesel & Turbo. Major recent projects, such as the New Suez Canal and the multi-billion-dollar expansion of Sri Lanka’s Port of Colombo, highlight the continued growth in global shipping volumes that keeps demand high for such large-scale dredging vessels. Currently, MAN Diesel & Turbo has 14 48/60CR engines on order for installation aboard new dredgers for customers in Benelux countries and China. THE OIL AND GAS SECTOR is by definition volatile, with construction very much linked to oil price, says Rasmus Hedemark. “Currently, there is a slight downturn due to the lower

nificant but can take time to maximize because of an order-to-operation process that takes up to three years to complete. As Rudi Ter Harkel explains: “The first 12 to 16 months are taken up by the relevant engineering and manufacturing processes. Once the compressor has been built, it is shipped to the customer and installed – a process that takes several months to complete. The end customer then starts their own commissioning phase, connecting the compressor to the rest of the machinery required for their specific production process.” so, When It coMes to the installation of air separation machinery, it’s a case of “Good things take time!” Still, demand isn’t slowing down. Since the launch of the first generation RIKT compressor in 2001, over 200 units have been sold, and order books are nicely filled for the latest second-generation machines, launched at the end of 2014.

In one of the latest ASU projects, Air Liquide will use MAN AIRMAX technology to build the world’s largest air separation unit in Secunda, South Africa. With a production capacity of 5,000 tonnes of oxygen per day, the ultra-modern facility pushes technical boundaries. The AIRMAX train, being the heart of the plant, comprises a main air compressor of the largest MAX1 type (AR140), and an RG 71-4 booster compressor. In this project, a 65 MW electric motor drives the main air compressor. This differs from the typical train concept, shown in the infographic, where both compressors are driven by a steam turbine. Once again, this is a proof of the flexible, highly efficient air separation solutions that MAN Diesel & Turbo provides.

THE ROAD TO
DECARBONIZATION The logistics sector is under pressure to cut CO2 emissions. While plenty has already been achieved, the road to decarbonization remains long and steep, says Prof. Dr. Alan McKinnon, one of the industry’s leading authorities on decarbonization. In the coming decades, companies will be put under increasing pressure to decarbonize their activities. The UN COP21 climate change conference, taking place later this year in Paris, aims to achieve international agreement on global decarbonization – but there are already concerns that the targets are unrealistic. Participating countries have indicated the level of savings in CO2 emissions they can achieve by 2050. When combined and factored into climate models, the figures show a global temperature increase of 2.7 degrees centigrade, well above the 2 degrees centigrade figure generally consiTo achieve it, greenhouse gas (GHG) emissions need to drop 60% worldwide by 2050 relative to a 1990 base year. The European Commission is aiming for an 80% - 95% reduction for the EU economy as a whole, and a 60% reduction for transport. The target for transport, particu-

Many ships burn so called "bunker fuel" rich in sulfur, which is left as a residual fraction in the refining process when cleaner "distillate" fuels, mainly petrol and diesel used in surface transport, have been extracted. The IMO now limits the sulfur content in bunker fuel to 4.5% and this maximum will drop to 1.5% by 2020.

The longer it takes us to get onto the right carbon pathway, the harder it will become. The road to logistics decarbonization is likely to be long and steep.

the sea, MAN Diesel & Turbo has provided the world’s first subsea compressor for a major oil and gas customer, to extract hydrocarbons like natural gas. For this challenging task, this cutting edge compressor can withstand really harsh conditions, enabling the production of additional 300 million barrels of oil equivalent. This makes subsea production more efficient and more reliable, and additionally reduces the risk of adverse environmental impact.
