Wood Group GTS has secured a $3.2 million contract from National Grid to provide gas turbine icon™ governor control system upgrades to nine Rolls-Royce Avon gas turbines, including an additional governor to act as a rotational spare. The upgrades will be fitted to gas turbines operating at compressor stations located in Cambridge, Diss, Chelmsford and Huntingdon in the United Kingdom. The icon governor control system regulates fuel flow into the gas turbine, providing stable operation across the turbine performance range from no load to full load conditions. This upgrade will address equipment obsolescence, enabling the continued operation of all four compressor stations and providing increased flexibility to ensure the essential flow of natural gas across the UK network.
