Damen Shipyards Hardinxveld has delivered a new crane vessel to Waternet Amsterdam, the organisation responsible for delivering fresh water and associated management services to 1.3 million people in and around Amsterdam.

WN25 measures 18 metres long and has been adapted to meet Waternet’s exact requirements. Its hull shape has been modified to reduce the suction effect when sailing close to the side of a channel and through bridges.

To minimise emissions, it has a hybrid propulsion system with lithium-ion batteries installed in a dedicated air-conditioned section of the vessel, charged by an EU Stage V certificated engine.

With a capacity of 138 kWh, the batteries deliver a maximum speed of eight knots and an endurance of 3.5 hours at 6.5 knots, plus a bollard pull of 2.1 tonnes. In addition, the wheelhouse has been redesigned, allowing it to be dropped in order to minimise the air draught and both it and the accommodation are also air-conditioned.
