All-electric ferry with eyes on the prize

Bryggen is one of five Damen Ferries 2306 E3 delivered to Arriva Denmark in Copenhagen last summer. The nomination committee recognises that this new class is an exceptional design that implements a range of innovative digital shipbuilding techniques including remote measurement via a network of sensors placed inside the vessel. These deliver a better financial return and a reduction in maintenance downtime. Another key feature is the innovative automatic mooring system that establishes a safe connection between the ship and the high-speed onshore charging system.

Computational fluid dynamics (CFD) were used to optimise the hull design by minimising water resistance, while cutting-edge software measured the relationship between engine torque and propeller speed. This enabled the optimisation of the battery array so as to minimise its weight, energy consumption and cost of operation while delivering the required performance.

The installation of sensors throughout these vessels allows Damen’s remote monitoring department to create a bespoke dashboard tracking key elements such as sailing patterns, battery lifecycle and swell dynamics. The data is then used to fine-tune the ferries to deliver greater efficiencies and reduce the downtime required for maintenance.

For Arriva Denmark, Damen delivered a turnkey package by acting as the complete solution provider. This has involved implementing the solutions required for the shoreside supply of renewable electrical energy.
