A North Sea oil firm has revealed plans to cut the pay of 830 Aberdeen-based employees.

Amec Foster Wheeler plans to reduce the salaries of onshore and offshore contractors by 7.5% from February 8.

The move follows similar pay cuts and freezes by BP, Shell and Wood Group amid a slump in the value of oil.

A barrel of Brent Crude was trading at $30 on Tuesday after falling nearly 75% from a high of $110 in June 2014.

Amec managing director for upstream asset solutions Alan Johnstone said: "The industry continues to face challenging times and after much consideration, we have taken the difficult decision to reduce contractor rates.

"We are determined to keep our business and the industry sustainable for the long term and this is just one of many measures to address cost and efficiency."

More than 65,000 people have lost their jobs since the slump began in late 2013 and thousands more remain under threat.

Last week, BP and Petrofac separately announced plans to cut hundreds of jobs as the price of oil hit a 12-year before rallying slightly.

Industry body Oil and Gas UK predicted this month that British hydrocarbon production rose 7% in 2015.

Despite forecasting the first rise in production in 15 years, experts warned further industry cuts are likely.
