Wärtsilä has supplied the ship design for the ‘Vestland Cygnus’, a Platform Supply Vessel (PSV) owned by Norway based Norside AS that is to be converted to serve as an offshore wind farm service vessel. The conversion took place at the Fjellstrand yard in Norway.
The re-design includes several new features, such as an accommodation module for 134 people, a 100 ton offshore crane with a range of 40 metres, and a new footpath system for transferring personnel to offshore fixtures. The vessel will have SPS (Special Purpose Ships) class notation.
Following completion of the rebuild project, the ‘Vestland Cygnus’, will transport service personnel to and from wind farms. It will be operated by Vestland Offshore, a Norway based offshore vessel operator.
The original ‘Vestland Cygnus’ design was supplied by Wärtsilä and the ship was delivered from the Fjellstrand yard in April 2015. Wärtsilä also supplied a complete electric propulsion system based on the Wärtsilä Low Loss concept with four Wärtsilä 20 engines, as well as an integrated automation system.
The new design will enable the transportation and accommodation of a high number of people. It is important that the vessel has very good stability, even in the most challenging sea and weather conditions, so that personnel can safely board rigs or wind mills. We are confident that the Wärtsilä design meets all our requirements.
