HELSINKI, Finland -- Sartor Shipping has contracted Wärtsilä to provide the VS465 vessel design and diesel electric propulsion system for a new field support vessel to be built in Norway.
The ship, which will be constructed by the Bergen Group BMV shipyard, will be owned and operated by Sartor, supporting activity on Statoil’s North Sea fields.
Wärtsilä Ship Power will supply two Wärtsilä 6L32 and two Wärtsilä 6L20 generating sets, the electric and automation systems, the frequency drives, the gear and controllable pitch propeller, the tunnel thrusters, and a retractable thruster. This will be the first installation of the Wärtsilä 32 engine, with power output increased from 500 kW to 575 kW/cylinder.
The ship will incorporate Wärtsilä's Low Loss Concept (LLC), an energy-efficient, redundant power distribution system for electric propulsion applications. The combination of the higher engine output and LLC should minimize fuel consumption and exhaust gas emissions.
A new feature will be 4-split reliability on both the electrical (LLC) and mechanical side. The 4-split concept, according to Wärtsilä, means that no single failure should result in a loss of power or capability of more than 25%. Traditional vessels have a 2-split design, which brings the risk of a 50% loss, the company adds.
