In line with DFDS's short-term climate action plan to reduce emissions by 45 % from 2008 to 2030, the company has upgraded and rebuilt the propulsion and control system of ro-pax vessel 'Dover Seaways in order to save fuel and CO2 emissions.

During an 18-day drydocking in Dunkerque, the new systems were installed and tested under LR supervision.

DFDS Performance Manager Lina Barsøe Christensen said: "Our short-term climate action plan consists of projects that fall into three categories. So far, we have planned projects that are anti-fouling initiatives – using coating and surface treatment on a ship to control or prevent the attachment of unwanted organisms.  Some projects deal with technical hardware upgrades. And finally, we have the Fuel Performance Programme projects, including hardware updates and software for decision support on board and insights ashore. More projects will be added as we learn more about how effective each project is.”

Superintendent Jan Blak said: “By applying the latest technology within route planning and propulsion control to the existing machinery installations and bridge control equipment, and utilising the full design potential of the machinery, we hope to see fuel and CO2 savings of up to 6 %. Specifically, we are installing an Artificial Intelligence-supported system that will optimise the relation between propeller pitch and engine RPM, taking these two components to the point where the propeller efficiency is at its maximum in relation to the Expected Time of Arrival for which you have programmed your system."

“To achieve the optimal settings, the system continuously looks at parameters like the ship’s position, speed and course over ground, the water depth below the keel, the engine load and the engine maker’s recommendations, fuel consumption, as well as the wind direction and speed. Based on all of this data, the system will automatically maintain the speed, propeller pitch and RPM, which will take you to your destination port on time at the lowest possible overall fuel consumption,” said Blak.

The equipment that was replaced or extensively modified included the RPM control devices, the optic fibre communication systems between bridge and engine room and the fuel oil flow meters. A server system that constantly monitors and controls the process based on the ECDIS system was installed. This server system is constantly connected to the Internet via the ship’s VSAT system to receive updated weather forecasts, as well as enabling shore-based DFDS personnel to monitor performance.
