Wood Group is in consultation over jobs at the Sullom Voe Terminal in Shetland.
The move comes after a previous round of job losses in October last year on the BP-operated Terminal.
It’s understood 23 roles are up for consultation.
The decision is understood to be a continuation of the change in work scope which was previously announced.
Earlier this month it was revealed Wood Group workers were facing consultation on Shell’s North Sea assets as well as changes to pay conditions.
A spokeswoman for Wood Group said:“We continuously review our resource requirements to meet our customer needs and to drive efficiency and effectiveness in our service provision. We are committed to working closely with employees and unions during this period of consultation.”
There are currently 164 personnel employed on the contract.
Earlier today STATS Group announced it would be making up to 50 redundancies from its UK operations.
