A2Sea's Sea Installer has been used for installation of two Siemens 6MW 120m turbines at the Gunfleet Sands 3 demonstration project, which will spark full-scale offshore testing of the eagerly awaited model.
Speaking with “uåX˜äŠÊ˜·³Ç Offshore, A2Sea chief executive, Jens Frederik Hansen, said the first test for its new purpose-built jack-up vessel was "a first small job that had an excellent result".
"Sea Installer showed already on the first test that some of the advantages built into this second-generation vessel worked as expected," said Hansen. "The first positioning of the vessel was done with an incredible accuracy of 3cm. After a penetration of the legs with large spud cans many meters into the seabed, they were efficiently and quickly retracted from the seabed with the purpose-built water injection system."
As previously reported by “uåX˜äŠÊ˜·³Ç Offshore, Sea Installer's next job will involve installing turbines at Dong's 400MW Anholt offshore wind farm, in Denmark.
From April, Sea Installer will be enganged for a year on West of Duddon Sands, starting with foundations installation, moving on to transition pieces and finally 108 Siemens 3.6MW turbines.
A2Sea is an offshore wind-specific company owned jointly by Dong and Siemens. Its revenue has grown by more than 500% in five years. Sea Installer is the company's first purpose-built vessel.
