First transition pieces installed at Anholt

The operation was performed as planned, with Jumbo once again proving to have an efficient concept for the transport and installation of wind farm foundations with the use of only one free floating vessel on DP.

After loading the first nine transition pieces in Aalborg, Denmark, they were transported to the offshore location. There, the Jumbo Javelin positioned itself on DP next to the pre-installed monopiles and lifted the TPs from its hold onto the monopiles. After leveling the TPs to their final position, the grouting procedure was executed.

Anholt Offshore Wind Farm is being built by DONG Energy. Jumbo is working for the Danish contractor MT Højgaard, which is in charge of installation of the foundations.

The Jumbo Javelin is able to carry nine TPs at a time, each with weights up to 200t. All TPs can be stowed vertically in the hold of the vessel for transport to the offshore location. The ship is free floating and uses its DP2 system to create a stable working environment in which TPs can be installed. With two cranes and a high transit speed of up to 17 knots, the vessel is well equipped for efficient wind farm installation work.
