Scheduled to enter into service in March 2013, the two 30m-long (“WindServer 30”) and four 25m-long (“WindServer 25”) vessels with a service speed of 25 knots will have the capacity to carry 12 and 25 service personnel, respectively.
Both “WindServer” types have a number of innovative features, designed to improve access to offshore installations in rough weather, improve fuel efficiency, ensure the safety of the personnel on board, and reduce running costs, the classification society said. Four engines power two controllable pitch propellers, giving improved operational flexibility while ensuring redundant capacity.
The vessels will also be equipped with ballasting systems allowing them to shift between a rough weather SWATH mode and a light weight transit mode. A fixed stabilisation foil adds to the design's stability - one of a set of permanently integrated motion damping devices that are part of the hull concept and designed to reduce construction and maintenance costs by avoiding complex active motion control systems.
