CASE STUDY
BRINGING OIL AND GAS EXPERIENCE TO OFFSHORE WIND
FOUNDOCEAN
We introduce FoundOcean as a company who have a few stories to tell and we will be featuring them in future editions.
We start with a case study – as expressed before case studies demonstrate real world situations and therefore the proof of what companies can achieve for their clients and customers.
EXPERIENCE FoundOcean has over 45 years’ experience of subsea and offshore grouting for the global energy construction industries. Grout is the fundamental element to all that FoundOcean does. The company has already completed grouting operations for five offshore renewables projects in and around the North Sea since 2009 and this figure is set to rise sharply in the next five years.
REALISTIC PREDICTIONS
In the next five years, an estimated 4,000 new fixed structures are scheduled to be installed in the North Sea alone. This is mainly due to the upsurge in offshore wind activity associated with Round 2 and Round 3 projects. FoundOcean has already been contracted to complete grouting operations for two offshore wind farms (272 turbine foundations) starting in 2012, and is in final negotiations for a further two projects, again starting this year, and continuing into 2013.
ORMOND OFFSHORE WIND FARM One of those projects is the Ormonde Offshore Wind Farm, located 10km off Barrow-In-Furness, in the Irish Sea. The wind farm is in the final construction stages, with the 30 RePower 5MW wind turbines being fitted as weather allows. This is sufficient to supply the equivalent of approximately 100,000 homes per year with clean power. The turbines will cover an area of nearly nine square kilometers.
The wind farm utilises jacket-type foundations similar to those used at many offshore oil and gas platforms. The combination of the size of turbine and a silty seabed will have influenced this choice. Ormonde was the first large-scale commercial wind farm in European waters to use jackets for the turbine foundations, as well as the substation foundations. Other offshore wind farms, in various stages of construction, to also use jacket-type foundations are Thornton Bank II and III, and Nordsee Ost.
