    Crane information

    The versatile crane can lift and install a full range of offshore wind foundations including tall jacket structures, and the largest monopiles. The crane operates in two main modes, either with one main hook of 3,000 MT or with dual hooks of 2 x 1,500 MT. Monopiles are never held in suspension during installation. They are either in their storage position, in the deck mounted transportation system or in the upending tool which hands the monopile directly into the pile gripper frame.
