Voith propulsion for second turbine ship

Importer
A2SEA’s wind installation ships, powered by a Voith VSP and VIT package

Both ships will be equipped with Voith Schneider propellers and Voith inline thrusters. The sister ship, ordered by A2SEA, based in Fredericia, Denmark, is to be built in China by the Cosco Shipyard Group, where Sea Installer is now nearing completion. The new vessel, with a crane capacity of 900 tons, is scheduled to enter service in mid-2014.

The three Voith Schneider propellers used as main propulsion will have a propulsion power of 3,800kW each. A VIT2300-1500 Voith inline thruster with an input power of 1,500kW will be instalkled in the bow. According to Voith, this is the largest thruster to use permanent magnet synchronous technology, commonly known as RIM drive. The VIT is claimed to offer extremely low noise emissions, very smooth running and low vibrations, compared with conventional thrusters. Compact dimensions mean that it can be mounted in limited installation spaces.

The new order differs from Sea Installer in one respect – a 100t greater crane capacity, which will enable to provide the wind energy sector with even bigger offshore wind turbines. At 132m length oa, 39m beam and total capacity of 5,000t, the installation ships are capable of carrying 60 personnel as well as eight to 10 complete wind turbines.
