National Oilwell Varco (NOV) said it will reduce its headcount by up to 900 positions as it looks to reduce costs amid the continued low oil price.
The decision by the company means the number of job cuts it has made this year total around 2,400.
Earlier this year the company revealed it would be making a number of losses from its North Sea operations.
Staff have been informed of the move which will also result in manufacturing operations being shut down in the south and west of the country.
A spokesman said:”The management of National Oilwell Varco Norway understands that this creates uncertainty among our many employees.
“We will continue to focus on the importance of carrying out an orderly process that takes care of all employees in the best possible way.”
