Peel Ports, the operators of Hunterston terminal, say they are working with Valaris to help them address the power issues on the drill ships.

Concerns were raised by Fairlie Community Council regarding the 24 hour a day use of diesel generators to provide power for the two giant vessels.

Peel Ports Clydeport director Jim McSporran said: "We are addressing concerns over the use of generators to supply power to the two vessels, and are working with the ships and a firm of electrical engineers to design a shore power option.

" I would point out that generator use is standard practice in ports throughout the UK.

"In addition we are currently monitoring noise levels at Fairlie foreshore and other locations, and comparing them to historical data to ensure they are kept within acceptable parameters."
