GeoSea Issues Westermost Rough Project Update

GeoSea has 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 kilometres off the coast of Hull, in the North East 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.

The company utilised the 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 were then transported across the North Sea to be installed immediately at the off shore site.

The company took steps to involve local (UK) content in the project by bringing in and facilitating the involvement of the UK’s east coast companies.

GeoSea established a UK project office in Grimsby port, from where the secondary works (small works and final touch-ups) on the foundations have been executed.

The INNOVATION has docked in the TeesPort, for the purpose of vessel preparation, mobilization and demobilization works, where local companies executed all the works.

The vessel’s improved performance is due to the use of a new, highly sophisticated piling frame and improved jacking procedures, both developed by GeoSea’s in-house engineering department. This approach allows the vessel to work in higher sea states and leads to decreased cycle times.
