(OSE: STL, NYSE: STO) This move against the Federation of Oil Workers Trade Unions (OFS) and the Norwegian Association for Supervisors follows a deadlock in the strike which they initiated on 18 June.
According to the OLF, a stoppage will lead to an almost complete shutdown of oil and gas production on the NCS.
Statoil-operated fields stand to suffer a daily loss of some 1.4 million barrels of oil and condensate and roughly 150 million cubic metres of gas.
The group itself will be losing roughly 585,000 barrels of oil and condensate and some 60 million cubic metres of gas per day from its own or partner-operated fields.
Statoil is now planning a controlled shut-down of production and return of personnel to land. An appropriate safety staffing will be established on each installation.
The lock-out warning embraces all members of the OFS and Supervisors not already taken out on strike. Roughly 1,800 members of these unions in Statoil will then be involved in the conflict.
Shutting down production on the NCS will also have consequences for the group's facilities on land, and the extent of these effects is now being identified.
Statoil will keep customers informed about the possible impact on its oil and gas commitments.
