Propulsion for another turbine installer

Voith has now been awarded the contract to outfit another vessel with this propulsion system. The new vessel, with a crane capacity of 900 tonnes, is scheduled to enter service in mid-2014.

A2SEA, based in Fredericia, Denmark, specializes in the installation of offshore wind turbines. After the Sea Installer, the company has placed another order for an offshore vessel with the Chinese Cosco Shipyard Group Co. Ltd. As was the case with the Sea Installer, which is nearing completion and will soon be transferred to Europe, Voith will provide the propulsion system for this new vessel.

The three Voith Schneider Propellers used as the main propulsion system for the newbuild have a propulsion power of 3,800 kW each. They ensure safe navigation, particularly so in dynamic positioning (DP) mode and during transits in extremely rough seas. In the bow area, the shipyard installs a VIT 2300 – 1500 Voith Inline Thruster with an input power of

1,500 kW. This thruster is the largest using the permanent magnetic synchronous machine technology (RIM Drive).

Compared to conventional transverse thrusters, the VIT stands out due to its extremely low noise emissions, very smooth running and low vibrations. As the entire propulsion system is very compact, it can also be mounted in very limited installation spaces.
