38 m multi-purpose workboat.
Buoy handling, fairway maintenance, marine research and pollution response, on a gas-electric driveline with battery hybrid.
Propulsion
Gas-electric with battery hybrid.
Four gas generating sets of 350 kW each feed an electric propulsion train with a 400 kWh battery, with biomethane as the primary fuel. On battery alone the vessel runs for two hours at five knots, or holds station for ten hours at anchor with the engines shut down.
