HYWIND DEMO PROJECT – MARINE WARRANTY SERVICES

Global Maritime have been awarded the Marine Warranty Services for the Hywind Demo Project. The installation is planned summer 2009.

Project Description:
The Hywind demonstration unit will be the world’s first floating full scale wind turbine.The design is based on a spar buoy concept consisting of a slender tubular steel with a draft of approximately 100 meters, a steel tower which is 65 meters above sea level, and a wind turbine generator on top. The unit is anchored by three mooring lines and conventional drag anchors.The Hywind Demo Project objective is to develop commercially attractive solutions for future floating offshore wind farms. This will be done by using new, cost-efficient and simplified solutions with adapted use of equipment, fabrication methods and installation methods.The demonstration unit will be equipped with a 2.3 MW wind turbine generator. The turbine will be connected via a subsea power cable to the local grid onshore Karmøy at Røyrvika substation.

The project will include 4 separate contracts:

• Turbine and upper tower
• Substructure
• Subsea cable
• Onshore civil/electro works

The Hywind demonstration unit shall be located approximately 10 km west of Karmøy, Norway, at a depth of about 200 m.
