Industrial strike action by Norwegian offshore workers entered a second week after talks with employers failed to resolve a dispute regarding pensions.
The SAFE trade union said in a statement on its website: "It was clear there was no basis to continue the talks."
Meanwhile, the Norwegian Oil Industry Association said in a statement: "Unreasonable demands for early retirement mean that we cannot agree."
Labour unions met on 6 July to decide whether to escalate the strike, which may have an impact on more oil fields.
Statoil said it is planning to shutdown production on the Norwegian continental shelf (NCS), following a notice of lockout by the Norwegian Oil Industry Association (OLF).
The lockout was imposed on all members of Industri Energi, the Organisation of Energy Personnel (SAFE) and the Norwegian Organisation of Managers and Executives who are covered by the offshore pay agreements.
The notice follows strike action taken by workers form Industri Energi, SAFE and Lederne on 24 June.
Cost overruns and technical setbacks have led British Petroleum (BP) to suspend its $1.5bn Liberty offshore project in Alaska.
Liberty offshore oilfield is located four miles off the northern coast of Alaska in Foggy Island Bay, in the Beaufort Sea.
Dawn Patience, BP Exploration (Alaska) spokesperson, was quoted by Reuters as saying that an 18-month company review concluded that the Liberty project, a field with about 100 million barrels of recoverable oil, should not go forward as planned.
"We are not going to pursue Liberty in its present form. The project, as it’s designed right now, doesn’t meet BP’s standards," said Patience.
