Mammoet has completed the installation of four 7MW wind turbines at the Nissum Bredning near shore wind farm in Denmark. Located in the Bay of Thyborøn, Nissum Bredning cannot be accessed by these specialist vessels due to the seabed conditions and shallow water depths of only three meters.
Mammoet proposed a barge with an integrated ballasting system which allowed it to be lowered and grounded onto the seabed. This provided the necessary stability for the operation while eliminating the need for dredging. The solution effectively resembled an onshore installation and also simplified matters, as now the lift could be performed with a LR11350 crane.
