New Vessel Receiving Equipment, Design From Wärtsilä

Posted on May 3, 2011

Wärtsilä has been contracted to supply the vessel design and complete diesel electric drive installation for a new field support vessel. Sartor Shipping of Norway will own and operate the ship, which will serve the North Sea oilfields on behalf of Statoil.

Sartor Shipping has contracted the VS465 design from Wärtsilä Ship Design. The Bergen Group BMV shipyard in Norway, which is to build the vessel, placed the order for the complete diesel electric propulsion system from Wärtsilä Ship Power. The scope of supply includes two Wärtsilä 6L32 and two Wärtsilä 6L20 generating sets, the electric and automation systems, the frequency drives, the gear and controllable pitch propeller and the tunnel thrusters, as well as a retractable thruster.

This will be the first installation of the Wärtsilä 32 engine with its power output increased from 500 to 575 kW/cylinder. The ship will also feature Wärtsilä’s Low Loss Concept (LLC), a power distribution system for electric propulsion applications. The combination of the higher engine output and LLC means that fuel consumption and exhaust gas emissions will be minimized, the company said.

The vessel will also feature four-split reliability on both the electrical (LLC) and mechanical side. The four-split concept means that no single failure will result in more than a 25% loss of power or capability, according to Wärtsilä.
