Self-elevating unit JB-117 has completed a crane- and accommodation support contract for General Electric at the DolWin3 offshore power grid connection.
The JB-117 was then immediately deployed for continuing operations at the nearby BorWin3 offshore grid connection for Petrofac. For both projects the European electricity transmission system operator TenneT is the end-client.
The scope of work for the JB-117 is similar for both projects. In terms of scale, the vessel’s crane has a 98-metre long boom. As the DolWin3 project has shown, the sheer size of the crane in combination with its heavy lifting capacity has meant that every part of the substations could be reached.
The DolWin3 project was also substantial regarding accommodation; at peak activity, JB-117 was home to 180 offshore personnel.
