This week Subsea 7 revealed it would be reducing its headcount by 2,500 in total in the next year.
The move will see initial changes in both Aberdeen, London and Norway.
With 410 positions are expected to go in the UK.
Meanwhile in Norway up to 210 positions will go.
The company also revealed that it would also be reducing its fleet by 11 vessels.
The chief executive of the OGA (Oil & Gas Authority), Andy Samuel, made a number of senior appointments to his team this week.
It comes after a number of previous appointments earlier this year with the new directors expected to be in post by mid-June.
Gunther Newcombe has been appointed as director, Exploration and Production, Angela Seeney as director, Technology and Projects, Hedvig Ljungerud as director, Policy, Performance and Economics, and John Ogden as chief financial officer.
These new directors will report directly to Andy Samuel and will sit on the OGA Leadership Team alongside Simon Toole, director, Licensing and Legal, and Stuart Payne, director of Change and Organisational Design, who were appointed earlier this year. The new directors will be in post by mid-June.
Concern has also been raised that major international firms are gearing up to sell North Sea oil and gas assets worth more than £2.5billion in the near future.
The slight upturn in crude prices since January and the award of a tax break in the budget have not been enough to convince certain companies that operating the aging and costly North Sea basin can be made worth their while near term.
Les Linklater, executive director at Step Change in Safety, said it was time for the industry to stop pondering what changes could be made and to start embracing them.
Wood Group chief executive Bob Keiller said thousands of job cuts in the global oil and gas industry are an unfortunate but necessary step in making sure firms can survive the current downturn.
Speaking after Aberdeen-based energy service giant Wood Group’s latest annual meeting, Mr Keiller said he knew only too well about the devastation that can be caused by the loss of someone’s employment.
He added: “Of course it has a huge impact on people and their families.
“It is the toughest aspect of any senior management role.”
Mr Keiller, who’s own family has experienced the impact of redundancy and the loss of self-esteem which often follows, said: “I am brutally and acutely aware of the human impact it can have.”
But it is also impossible to ignore the impact of the recent plunge in oil prices, he said, adding: “Companies have no choice but to let people go if they want to survive and provide jobs in the middle and longer-term.”
He said there were “too many moving parts” to current market conditions to say with any degree of certainty if the industry-wide job cutting has reached its peak.
