Petrofac and GE have announced a contract worth over GBP 110 million to engineer, construct and install a turnkey power system to efficiently connect up to 336MW from the Galloper Offshore Wind Farm off the coast of Suffolk, U.K., to the British grid.
Petrofac will provide topside and jacket foundation designs, fabrication, transport and installation of the offshore substation and offshore logistics to support hook up and commissioning while GE will provide overall electrical system design in addition to:
- Onshore and offshore substation equipment and all related power transformers and gas insulated switchgear at 132kV and 33kV
- Two Static Var Compensators, each connected to the grid by its own power transformer
- Protection and control for the safe operation of the wind farm including the telecommunications needed between the onshore and offshore substations and the wider network
- All ancillary and supporting electrical equipment such as auxiliary and earthing transformers, battery systems, back-up generators and low voltage systems
Construction will continue through 2016 with the offshore substation scheduled to be installed in 2017. The wind farm will commence operations in March 2018.
