About 1,200 contractors will resume the strike for 48 hours from Wednesday, the Unite union announced.
With the rising cost of energy, profits have soared for fossil fuel companies, with BP and Shell posting a combined surplus of £11.7bn in the first quarter of 2023.
They will be among the companies affected by the industrial action, along with Apache, Harbor Energy, Enquest, Ithaca, Repsol and TAQA.
The prospective action includes electrical, mechanical and production technicians, plus deck crews, scaffolders, crane operators, pipefitters, planers and riggers working for Bilfinger UK Limited, Petrofac Facilities Management, Stork Technical Services, Sparrows Offshore Services and Wood Group.
Unite General Secretary Sharon Graham said: “Oil and gas corporations continue to enjoy a speculative bonanza. Unite members are fully intent on getting a much larger share of the profits these oil giants make. And they deserve it.
“The latest round of 48-hour strikes is just the next step in our fight to create better jobs, wages and conditions in the offshore sector. Unite is prepared to fight for the long haul as the union has to challenge unrestrained corporate greed. .”
Unite estimates that the impending 48-hour round of strike action will involve around 200 Bilfinger contractors working on BP and Repsol assets, while around 650 offshore Stork members will join the walkout due to no better salary offers.
Around 200 offshore workers employed by Sparrows will also take part in the strike. Unite can confirm that this excludes our members in the BP units (Andrew, Etap, Clair, Clair Ridge, Glen Lyon and Mungo) and Enquest units (Heather, Magnus and Thistle) due to members accepting separate pay offers.
Unite members working for Petrofac at Ithaca FPF1 will also strike during the 48 hour period along with members employed by Wood Group at TAQA facilities. This action encompasses together about 150 members in total.
John Boland, Unite’s industrial officer, added: “We are witnessing the biggest wave of industrial action in a generation in the offshore sector.
Whether it’s better wages, fairer and safer job rotations or vacations, Unite members remain fully prepared to fight for a better deal.
About 1,200 offshore workers will be involved in the latest phase of the offshore industrial action, and believe us when we say this is causing widespread disruption to the operations of oil and gas corporations.”
The latest strike follows an earlier 48-hour stoppage (April 24-26) that caused “serious” problems for major oil and gas operators. Due to the Unite members’ strike, there was a widespread outage that led to the closure of the facility.
