The vessels consist of a hull, four legs and four electric rack and pinion jacking systems. They have a DP-2 dynamic positioning system using four propeller-driven thrusters, as well as a main crane with a lift capability of 300 tonnes and a smaller 50-tonne auxiliary crane. They are used for maintenance, modification, installation and decommissioning of offshore facilities predominantly in the UK, Dutch and Danish sectors of the North Sea.
The two vessels for Fred Olsen were built using a Gusto MSC NG-9000 design and are self-elevating and self-propelled offshore wind turbine installation vessels. The design weight of each exceeded 14,000 tonnes, and they are the largest Lamprell has ever built. The vessels are equipped with dynamic positioning, high-speed jacking systems, an 800-tonne crane and a rotary propulsion system that allows them to sail at a speed of 12 knots. Each unit includes accommodation for 80 personnel and has a payload capacity in excess of 5000Te.
