OFFSHORE GEOTECHNICAL operator Seacore has won a contract worth over £5M to install 30 large diameter monopile foundations for the 60MW North Hoyle offshore wind farm.
The wind farm, to be operated by National Wind Power, will lie about 10km off the coast of Rhyl, North Wales. It is one of 18 sites around the UK coast identified by Crown Estates for offshore wind farm development.
Seacore's contract includes design, construction and installation of a 50m meteorological mast.
The 4m diameter steel monopiles, ranging from 54m to 63m long and weighing between 240t and 275t, will each support a 2MW turbine with an 80m diameter, three-blade rotor. The wind turbines will have a hub height 70m above sea level.
Seacore will operate from its own eight-legged jack-up platform in about 12m of water. It plans to use its Teredo T40 reverse circulation drilling rig with a large hydraulic piling hammer in a 'drive, drill, drive' operation to install the monopiles.
