Viking Supply Ships said it has lay up one of its vessels as a result of the oil price decline.
The company will begin negotiations with employees and unions in a bid to assess the on-going crew situation as it looks to minimise job losses.
Viking said it has already implemented a cost reduction program and will further initiate a new market program with an ambition of further additional savings.
Earlier today Diamond Offshore Drilling said two contracts for a pair of rigs with Petrobras had been ended ahead of schedule.
