Eco-friendly ballast water on DFDS’ ships

As you may know, water is used as ballast on board ships to maintain safe operating conditions during a voyage by improving stability, reducing stress on the hull, and improving propulsion efficiency.

Last year, DFDS initiated a programme for installing ballast water treatment systems (BWTS) on all vessels in our fleet in order to support the marine environment and to comply with the international convention on ballast water management. The system prevents the spread of potentially invasive aquatic species through the use of ballast water on ships operating across different regions. This is done mechanically, using a combination of filtration and UV radiation to render the organisms non-viable.

For the last six months, the project team has been busy clarifying the batch 2020 ships’ system capacity needs, developing the new ship specific documentation, obtaining required approvals from the maritime authorities and planning the yard installations.

Jacob Johannesen, Project Manager & Naval Architect, Newbuilding & Major Conversions, says: “It is a challenging task to install the system with all its auxiliary components in an already-crowded machinery area. DFDS has teamed up with a design facility that uses a 3D scan of the relevant spaces to model the installation in a point cloud environment. This helps reduce the margin of error in the design and the installation time required.”

Five BWTS installations already in place

During the first two months of 2020, five BWTS installations have been made: Côte des Flandres, Regina Seaways, Dunkerque Seaways, Delft Seaways and Seven Sisters now all clean the water thoroughly before sending it back into the sea.

“Many colleagues within the organisation are involved with the programme during the different phases. However, a special thank-you must go to our good colleagues in Technical Organisation who are ensuring timely installations at the yard,” says Jacob.

Sofie Hebeltoft, Head of CSR, says: “Supporting the marine environment is part of our CSR strategy, and the installation of BWTS is an important part of this. It’s great to see how this is actually brought to life, both with the 3D simulation and the time-lapse film. Thank you to the team for sharing this with us.”

The programme will continue until end of 2024.
