Mammoet has supported the Seagreen offshore wind project construction, off Scotland, with its large ring crane solution.
The equipment allowed load-in and load-out of the jacket foundations to take place regardless of the tidal conditions and so reduce the downtime of offshore assets and help to deliver first power as scheduled.
Seagreen is the world’s deepest fixed bottom offshore wind farm to date, lying further from the coast where winds are stronger and more reliable.
Its 114 wind turbine foundation jackets stand 95 metres tall and are robust enough to support 10MW capacity Vestas turbines.
Offshore wind projects taking place in macrotidal environments, such as around the UK, must deal with water level changes of more than four metres every six hours.
This extreme tidal range is difficult to compensate for using ballasting, so Mammoet developed its crane solution to overcome this challenge at the Port of Nigg’s marshalling facility for Seagreen.
