Anholt wind farm for Jumbo

Jumbo Offshore has been awarded the transport and installation contract for all 111 transition pieces on the Anholt offshore wind farm in Denmark.

The 400 MW wind farm is being developed by DONG Energy and the contract was awarded by contractor MT Højgaard. The Anholt Wind Farm, in the Kattegat near Anholt Island, will be Denmark's largest offshore wind farm.

A DP2 offshore heavy lift vessel will be used to install the TPs on pre-installed monopiles, starting April 2012. The TPs, each weighing 200 tonnes and 17 m long by 5.5 m diameter, will be loaded at Bladt Industries in Aalborg, Denmark. The vessel will carry nine at a time.

The installation vessel's two 900 tonne capacity Huisman mast cranes will be re-reeved for the project. The mobilisation will include a motion-compensated bridge for access to the TP from the vessel, a grout plant, a purpose-built lifting beam, two passive lifting compensators, grillages and sea fastenings.

"Jumbo's installation method is a great match for this project and we are looking forward to working with them on the installation of the transition pieces on Anholt Offshore Wind Farm," said Kim Reinhard Andersen, energy & resources director at MT Højgaard. At the end of this job MT Højgaard will have installed 560 offshore wind turbine foundations, which is more than any other contractor in the world.
