Mech-Tool Engineering has delivered fire and blast walls for the 402MW Dudgeon offshore wind farm, off the coast of Norfolk, England, UK.

Sembmarine commissioned Mech-Tool to design, manufacture and supply the fire and blast walls.

The fire and blast walls will play a key role in safely generating offshore wind to power over 410,000 homes in the UK.

The wind farm will include 67 Siemens’ 6MW turbines, each with a hub height of 110m and 154m of rotor diameter.

The turbines will be supported on grounded monopile structures which reach underwater depths between 18 to 27m.

The project is expected to be commissioned in the second half of 2017. It will have a life expectancy of about 25 years.

In February this year, the wind farm delivered its first electricity. The foundations have already been installed and the turbine installation work has been initiated. First electricity generation was treated as a major milestone by the developers.

Statoil, Statkraft and Masdar own the wind farm, which is claimed to offset more than 570,000 tonnes of CO2 and 13,000 tonnes of SO2 per year.

Grid connection point for the wind farm will be located near Weybourne with Necton 400kV substation. A nominal voltage of 132kV of high voltage alternating current (HVAC) will be received by the substation.
