CHC Helicopter has entered into a consultation process with staff over job losses as it looks to streamline costs.
The company said a number of positions are likely to be affected including pilots, engineering and support staff.
The news comes after Bristow announced it was in consultation over job reductions.
A company spokesman said: “The offshore industry continues to face challenging conditions and we, like our customers and competitors, have had to keep our resourcing requirements under regular review.
“While we have worked diligently to address market conditions without affecting our wider workforce in Aberdeen, unfortunately we are unable to continue to do so.
“In the region of 50 positions may be affected at our Aberdeen base.”
“CHC will continue to work to reduce costs, strengthen our balance sheet and partner with customers to provide solutions that result in lower customer costs while maintaining an absolute commitment to industry leading safety, availability and reliability.”
CHC employs around 450 people in the UK.
Meanwhile Bristow said the total number of workers facing potential job losses stands at 130 – including up to 66 pilots – in jobs across the UK.
Bristow currently employs around 2,000 people in the UK.
The British Airline Pilots’ Association (BALPA) previously urged the government to hold a summit after the announcement from Bristow was made.
