Apache North Sea Workers Vote to Strike, Risking UK's Forties Oil Pipeline

Offshore workers employed by Apache in the North Sea have backed strike action in a dispute over pay, according to the Unite union, raising the possibility of disruption to the Forties pipeline system that moves a significant share of Britain's oil and gas to shore.

What is known so far

Around 160 offshore workers across seven Apache-operated assets linked to the Forties and Beryl oil fields were balloted on industrial action, energy industry outlet Energy-Pedia reported. The ballot opened on 3 September 2026 and closed on 1 October 2026, with workers voting in favour of a strike. Potential industrial action could begin from mid-October 2026, though an exact start date had not been announced as of 5 October 2026.

The workers involved include electrical, instrument, mechanical and production technicians, telecoms technicians and radio operators, according to Energy-Pedia. Unite describes itself as the UK's largest offshore union.

Why workers are striking

Unite says Apache's pay offer amounts to a real-terms pay cut for many staff, with increases ranging from a pay freeze to below the rate of inflation. The union also says Apache set deadlines over outstanding back pay and indicated some payments could be withheld, which Unite says could leave some workers thousands of pounds out of pocket, according to Energy-Pedia and GlobalBanking&Finance.

News outlet Newshub reported that Apache's offer to the bargaining unit was a 4% pay rise, which the company has said aligns with recent increases given to non-unionised staff.

Unite's industrial officer Stevie Davies said Apache had refused to negotiate in good faith with the union and had behaved in a hostile manner by proposing real-terms pay cuts and threatening to withhold back pay under arbitrary deadlines, according to Energy-Pedia.

Potential impact on fuel supplies

The dispute centres on the Charlie platform, one of Apache's seven affected North Sea assets. Unite has warned that a strike could bring Charlie to a standstill, reducing pressure in a way that could force the shutdown of the entire Forties Pipeline System (FPS), which is operated by Ineos, according to GlobalBanking&Finance and Newshub.

Both outlets cite Unite's estimate that the Forties system carries about 29% of UK oil production and 30% of UK gas supply. The two reports differ slightly on the pipeline's daily capacity: GlobalBanking&Finance put it at 575,000 barrels per day, while Newshub reported a figure of up to 600,000 barrels per day. GlobalBanking&Finance also noted that the pipeline exports Forties Blend crude, which underpins the Brent benchmark used in global oil pricing.

Newshub reported that Unite warned the dispute could have significant consequences for workers, operators and consumers, and that the UK's Department for Energy Security and Net Zero urged both sides to resolve the matter without causing disruption. The same report noted that UK diesel prices had briefly exceeded £2 per litre amid broader market pressures, without attributing that specifically to the strike threat.

Company position and financial context

Apache, part of US-based APA Corporation, has said its pay offer is in line with increases already granted to non-union staff, according to Newshub. Energy-Pedia reported that APA Corporation posted $1.7 billion in operating cash flow in the second quarter of 2026 and a net profit of £1.3 billion for 2025, figures Unite has cited in arguing the company can afford a higher offer.

None of the three reports reviewed for this article contained a direct, on-the-record company statement responding to the strike ballot result or addressing the specific claim that the Forties system could be forced offline.

What is still unclear

As of 5 October 2026, no confirmed strike start date had been set, and it remained unclear whether negotiations between Apache and Unite would resume before any action began. It was also not independently confirmed in the reports reviewed whether other operators using the Forties system would be able to keep exporting oil if Apache's Charlie platform stopped operating.
