August 30 - Danish construction company, MT H
The 400 MW wind farm, which is currently being developed by DONG Energy, is located in the 'Kattegat', near Anholt Island, and will be the largest offshore wind farm in Denmark. One of Jumbo's DP2 Offshore heavy lift vessels will install the TPs on pre-installed monopiles, starting April 2012.
Anholt is a result of Danish government policy, which aims for a society independent of fossil fuels. In 2020, 30 percent of gross consumption should come from renewable energy. For the Anholt contract, the TPs will be loaded at Bladt Industries in Aalborg, Denmark. Every TP weighs approx. 200 tonnes, is 17 m high and has a diameter of approximately 5.5 m.
Mobilisation is planned in Rotterdam, The Netherlands in early April 2012. The mobilisation will include a motion compensated access bridge (for safe access to the TP when the vessel is on DP), a grout plant, a purpose-built lifting beam, two passive lifting compensators of in-house design, grillages and seafastenings. The two 900 tonne Huisman mast cranes will be re-reeved to their project specific configuration.
For Jumbo, the contract is a recognition of the safe and efficient TP-installation works for the Greater Gabbard Offshore Wind Farm (UK). Jumbo's all-in-one installation method will be largely repeated for the Anholt contract. This method consists of loading 9 TPs at a time, transporting them to the site and installing them.
"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', says Kim Reinhard Andersen, energy & resources director at MT Højgaard. When the 111 foundations are in place, MT Højgaard will have installed a total of 560 offshore windmill foundations, which it claims is more than any other contractor in the world.
