Damen Shipyards Group has delivered five type 2306 E3 passenger ferries to Arriva Denmark which will operate the vessels in Copenhagen on behalf of Danish public transport agency Movia.

Damen's design philosophy behind these vessels is known as E3 – environmentally friendly, efficient in operation and economically viable - in accordance with Movia's declared aim when issuing the tender to upgrade the waterborne transport service in the city. The ferries are expected to make significant strides towards a zero emission service, reducing Copenhagen’s total public transport NOX emissions by 2.5%, CO2 emissions by 10% and particulate emissions by 66%.

According to Damen, the vessels' sustainable credentials are powered by a series of innovative, digital shipbuilding techniques, wth CFD technology applied to the hull design, minimising resistance in the water, while cutting-edge software measured the relationship between engine torque and propeller speed. This resulted in the optimal use of battery packs for reduced weight, energy consumption and – ultimately – costs of operation.

The ferries are prepared for remote monitoring. Informed by a network of sensors. Damen’s remote monitoring department is able to set up a dashboard tracking such things as sailing patterns, battery lifecycle and swell dynamics. This allows fine-tuning of the operation towards greater efficiency and reduced downtime for maintenance.

Damen has acted in this project as integrator and complete solution provider. This has included investigating shore solutions for electricity supply, in alignment with Movia’s requirement that 60% of the electricity for the operation comes from a sustainable source.

Martin Verstraaten, Damen sales manager, said: “This, in my opinion, is where Damen really add value to a project. Our involvement is not limited to the shipbuilding scope alone, we take responsibility for the entirety of the project. We provide a focal point where all partners involved the project come together to fulfil their individual roles in alignment with one another. With this, the project benefits from cohesive, centralised direction for maximum efficiency.”

Working closely together with Echandia Marine, Heliox and Staubli, Damen developed a solution that takes just seven minutes to charge the ferries at the end of each trip. The charging solution features an auto-mooring system to ensure a secure connection between the vessel and charging infrastructure.

Having recently unveiled its Electric Cutter Suction Dredger 650, Damen continues to work on a number of hybrid and electric designs. These include two fully electric ferries for Ontario, Canada, four (having delivered two to date) hybrid vessels, easily convertible to full electric propulsion in the future for BC Ferries in British Columbia, Canada and the first fully electric harbour tug with 70t bollard pull for the port of Auckland, New Zealand.
