Workers are thought to have downed tools on a North Sea oil rig in a protest against alleged poor working conditions.
A group of offshore whistle-blowers have posted messages on social media claiming 200 employees from Aker Solutions are undertaking an “unofficial” four hour “sit in” on the Mariner installation this morning.
A spokesman for the group said: “Lockdown on Mariner hook up as workforce bite back. Tomorrow brings a day of unofficial action against working conditions on the Mariner hook up.”
A spokesman for Aker Solutions said: “We have been made aware that some workers based at the Mariner field have chosen not to work today. The company has received no official notification of this activity and is looking into this matter.”
