Waves
2019 was a very challenging year with main focus the upcoming IMO 2020. After the first successful scrubber installation on Leo C, within April 2019, Danaos has incorporated scrubber monitoring into Waves system.

SCRUBBER MONITORING
The scrubber monitoring has been included in the Waves interactive map. Regulations compliance, operation details, technical details and alarm list are available for the user to check and monitor. Below is the main screen after entering the scrubber monitoring option and is the “Regulation compliance”. The “Scrubber state” bar indicates the operational status of the scrubber and vessel (at sea, at port, working ok or not). Relevant emissions and washwater limits have been inserted in order for any violation to be easily identified.
The map on the left shows the vessel’s route for the examined period. There is also a note about the ports where the operation of open loop scrubbers is prohibited.
Operational details include data about the ME and DG loads, Speed, SG load (if applicable), in order to ensure that the scrubber operates within its design limits. Moreover, in case DGs are operating partially in scrubber and there is also load at bypass, then same is depicted in this tab. Sea water flow, scrubber consumed power and sulphur of the fuel used is also included.
More technical data concerning the scrubber operation is also received and displayed, such as the turbidity filter inlet pressure, sea water supply pressure (upper and lower), exhaust gas pressure before & across scrubber and scrubber inlet pressure. The detailed breakdown for these parameters will provide a more detailed insight in the actual condition of the scrubber.
Electrical details show in detail the load of each working sea water pump and also the calculated load per reefer with its corresponding limit according to each vessel’s charter party.
The last tab, “Alarm list” includes signals about the activation of some critical alarms for the scrubber operation that indicate serious damage or may result to an emergency shut down of the system.
DCS
In addition, an important milestone in 2019, is the development of IMO DCS reporting in the Waves Fleet Performance platform. The IMO DCS routine has been incorporated in the MRV routine since they are both under the current emissions monitoring scheme.
WAVES is fully integrated in the Danaos management system, providing personalized role-specific dashboards and maritime business operational intelligence, creating a true competitive advantage in ship management. The incorporated algorithms and visualization tools transform data into useful information, assisting company’s employees with the decision-making process, while eliminating the reaction time. Within 2019 Danaos has managed to standardize the Charter Party format, and latest charter parties for all vessels have been inserted in Waves, going one step forward to a fully digitized company and in order for same to be available instantly. Another major routine designed and developed in late 2019 – early 2020, is the EEDI, EEXI & AER routine, in order to check where our vessels stand compared to the stricter upcoming EEDI regulations and Poseidon Principles AER limits. In an effort to evaluate the performance of the ship’s energy efficiency measures, Danaos has developed the corresponding EEDI (Energy Efficiency Design Index) index for all the company’s vessels regardless of the year of their construction (corresponding to the EVDI index developed by Carbon War Room and RightShip).
The above indicator was then calculated after optimization was completed on each ship, and its reduction coefficient was determined, which reflects the level of efficiency increase compared to that of the original design. Various compliance phases have been separated along with the various EEDI thresholds taking into account the reduction factors by IMO. At each phase, the number of compliant vessels are shown. It is noteworthy that after investing $ 87 million, an EEDI improvement of over 20% on over 60% of the fleet was achieved, while over 50% of the fleet is in phase 2 compliance, as shown in below graph.
The main finding is that these compliance rates increased significantly after the investments. In the following graph, we show how the CO 2 footprint for four distinctive carrier capacity categories ranging from 6,500 to 13,000 TEUs. The blue column depicts theoretical EEOI basis on initial vessel design and consumption on a specific route. The reduction in the index is above 50% for all ship categories as a result of the speed reduction and the improvements applied on each vessel.
Last but not least, Danaos has developed a tool within EEDI routine in order to predict the EEDI reduction if a specific investment is applied.
Under the same context and in order to benchmark our vessels in the Poseidon Principles, AER (Annual Efficiency Ratio) has been incorporated in Waves.
Below are WAVES’ major milestones presented for the year 2019:
January 2019: Hull cleaning timeline added under Performance motoring menu June 2019: Standard T/C Description application incorporated
December 2019: IMO-DCS featured in MRV routine
February 2019: MRV Routine tunings as per DNVGL requirements in order to check automatically all MRV related files for possible wrong entries
August 2019: Scrubber motoring featured on Map for Scrubber fitted vessels December 2019January 2020: EEDI, EEXI routines
For 2019, DANAOS focuses on turning its processes fully digitized via its state-of-the-art WAVES architecture, and be able to become a trusted link in the chain of new era of operations. Below is an illustration of the WAVES’ next steps for the year 2020.
