Heli-One is a subsidiary of CHC Helicopter Corporation
Up to 60 jobs are set to go at an Aberdeen helicopter maintenance firm.
Heli-One, a subsidiary of CHC Helicopter Corporation, has been hit by an "industry-wide downturn in activity".
The company said it regretted that between 50 and 60 jobs would be affected.
The news comes just days after job warnings from industry body Oil and Gas UK and the Aberdeen and Grampian Chamber of Commerce oil and gas survey.
CHC and Heli-one said in a statement: "CHC can confirm that its repair and overhaul division Heli-One commenced a consultation process over proposed redundancies at its base maintenance facility in Aberdeen.
"CHC has instigated the process in response to the industry-wide downturn in activity. The proposed redundancies, involving between 50 and 60 members of staff, would reduce personnel levels at the base to the level required for forecast future activity.
"CHC very much regrets having to take this measure but it is unavoidable in the present economic climate. The company will now liaise closely with union representatives during the consultation period."
The company said it planned to continue to employ about 25 people to provide logistics and design support.
