GeoSea record breaking performance on Westermost Rough
Zwijndrecht, 26 May 2014 – Yesterday GeoSea finalized the installation of the foundations for the Westermost Rough (UK) offshore wind farm project. This DONG Energy project consists of 35 wind turbine positions 9 km from the coast near Hull in the north east of England, UK.
As main contractor for the foundations GeoSea has been responsible for the transport and installation of the foundations, consisting of monopiles between 500T and 810T, with a diameter of 6,5m and transition pieces of around 367T.
For this job GeoSea has made use of the most dedicated offshore wind installation vessel INNOVATION owned by HGO, which is 50% owned by GeoSea.
The INNOVATION was loaded in Aalborg (Denmark) with 5 sets of monopiles and transition pieces which it then transported across the North Sea to be installed immediately at the off shore site, a distance of 500 nautical miles.
GeoSea took steps to involve local (UK) content in the project by bringing in and facilitating the involvement of UK east coast companies. GeoSea established a UK project office in Grimsby port, from where the secondary works (small works and final touchups) on the foundations have been executed. For the vessel preparation, mobilization and demobilization works INNOVATION has docked in the TeesPort, where local companies executed all the works.
The INNOVATION has achieved this unprecedented performance thanks to the use of a new and highly sophisticated piling frame and improved jacking procedures, both developed by GeoSea’s in-house engineering department. This innovative approach allows the INNOVATION to work in higher sea states and leads to decreased cycle times. Another important milestone is that this project was executed without a single LTI (Lost Time Injury), reflecting the high attention by GeoSea and DONG Energy to Health & Safety.
By managing the INNOVATION on this project GeoSea has set a new standard in offshore wind with the result that that this combination is a ready solution for future offshore wind projects with larger foundations and wind turbines.
GeoSea is a fast growing company specialising in complex offshore marine engineering projects. The company is part of the Belgian DEME Group that is active across the globe. GeoSea has participated in the construction of large-scale offshore wind farms including the Alpha Ventus project, the EnBW Baltic 2 wind farm, the Trianel West Borkum II wind farm in German waters, the Walney wind farms and at the Ormonde farm in the Irish Sea and the C-Power wind farm off the Belgian Coast. GeoSea‘s business also covers more traditional activities such as soil investigation, drilling of large diameter mono piles and high-tech directional drilling. GeoSeo relies on its ability to provide innovative techniques and high operational reliability through high-tech equipment. GeoSea’s jack-up platforms include Innovation (in co-ownership), Neptune, Goliath, Vagant, Buzzard, Zeebouwer, Halewijn, Tijl II, and Kobe.
The Belgian dredging, hydraulic engineering and environmental group
DEME has earned itself a prominent position on the world market in a few highly specialist and complex hydraulic disciplines. Having started out with dredging operations and reclamation, the group diversified into hydraulic projects at sea, services to oil and gas companies, the installation of offshore wind farms, environmental activities such as soil remediation and sludge recycling, and revalidation of brownfields and wreck clearance. Its multi-disciplinary know-how and experience, project synergies and integrated business structure allowed DEME to grow into a global solutions provider. The Group owns one of the most modern, high-tech and versatile fleets for dredging and hydraulic engineering activities. DEME employs 4,500 people. In 2013 the Group realised a turnover of EUR 2.5 billion.
