May 9 - Siemens Wind Power has contracted offshore marine and engineering consultancy Aqualis Offshore to provide a series of assessments for wind turbine service operations.

These will be performed by a jack-up vessel chartered by Siemens, which will be used in the maintenance of offshore wind turbines on a variety of wind farms in the North Sea.

Aqualis Offshore's office in London, UK, will conduct a series of generic assessments to cover a range of water depths and environmental conditions where the vessel is scheduled.

"Our task is to help determine the criteria within which a given jack-up vessel can operate most efficiently and safely," said David Wells, ceo of Aqualis Offshore, which is part of Oslo-listed Aqualis ASA.
