Damen Shipyards Group has delivered five Damen Ferries 2306 E3 to Arriva Denmark in Copenhagen, says a press release published on their website.
Damen’s E3 philosophy
Arriva is operating the vessels on behalf of Danish public transport agency Movia. The vessels are based on Damen’s E3 philosophy:
- environmentally friendly,
- efficient in operation and
- economically viable.
Journey towards a zero emissions future
Movia issued the public tender for waterborne public transport in Copenhagen with its aim:
- to upgrade the service,
- to make it cleaner and
- more sustainable.
These aims of Movia are in line with both Arriva and Damen.
- Arriva embraces innovation in order to reduce environmental impact, and
- Damen aims to become the world’s most sustainable shipbuilder.
Zero emission service
The ferries make significant strides towards a zero emission service, reducing Copenhagen’s public transport NOX emissions by 2.5%, CO2 emissions by 10% and particulate emissions by 66%.
Innovative digital techniques
The vessel’s sustainable credentials are powered by a series of innovative, digital shipbuilding techniques.
Computational fluid dynamics
Computational fluid dynamics (CFD) were applied to the hull design, minimising resistance in the water, while cutting-edge software measured the relationship between engine torque and propeller speed.
Optimal battery packs usage
This resulted in the optimal use of battery packs for reduced weight, energy consumption and – ultimately – costs of operation.
Remote monitoring and connectivity
The ferries are prepared for remote monitoring. Informed by a network of sensors incorporated into the vessel, 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.
For this project Damen has undertaken its role as integrator, or complete solution provider.
This has involved, for example 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.
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 they make. The charging solution features an innovative auto-mooring system to ensure a secure connection between the vessel and charging infrastructure.
Damen’s hybrid and electric projects
Having recently unveiled the Electric Cutter Suction Dredger 650, Damen continues to work on a number of hybrid and electric projects. 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 world’s first fully electric harbour tug with 70 tonnes bollard pull for the port of Auckland, New Zealand.
