Rosebank Oilfield Awaits UK Verdict: 122 Workers on Site, Decision Expected by Year-End

Since the UK government approved the Jackdaw gasfield on Wednesday, Oct. 21, the next North Sea decision has come into view: Rosebank, a far larger project with a far bigger carbon footprint and a far bigger tax prize.

A BBC crew landed on the Rosebank installation hours after the Jackdaw consent was granted. The facility is the Petrojarl Rosebank, a floating production vessel about 80 miles northwest of Shetland, chartered by the field's owners, Adura and Ithaca, from Aberdeen-based Altera. Altera CEO Chris Brett described the waters west of Shetland as "as harsh as you get anywhere in the world."

There are 122 people on board. Helideck lead Nicola Boyd works two weeks on and three weeks off. Lead mechanical technician Ewan Leonard said a 30-metre swell came through last week and that winter will bring more of it.

What Jackdaw settled, and what it did not

The government says Jackdaw will lift domestic gas production by about 6% at its peak, run for up to 11 years and add an estimated £2.9 billion to the UK economy. Adura, the Shell and Equinor joint venture behind it, says peak output could heat the equivalent of 1.4 million homes. Gas could start flowing as early as the end of this month.

The same announcement created an Energy Wealth Fund, seeded with £2 billion and meant to invest North Sea tax revenue in clean energy. President Donald Trump praised the approval on Truth Social, saying the UK should "go FULL BLAST."

Rosebank is a different animal. Officials told the Guardian that Fahnbulleh is minded to refuse it. They said the field would emit about seven times the carbon of Jackdaw and that she believes it does less for UK energy security because most of the oil would be exported.

Fahnbulleh told the Guardian: "One is a gasfield that caters for the domestic market, while the other is an oilfield that is mainly for export." She added that each application is judged on its own merits and must fit the UK's carbon budgets.

The Department for Energy Security and Net Zero called the reports "speculation." A spokesperson said each project will be assessed on its own merits. Officials say no final decision has been taken.

A split inside the government

The Treasury is pulling the other way. Healey told ITV he expects "oil and gas" revenues to feed the new wealth fund. The Guardian's sources say Burnham would make the final call if the two ministers conflict, and that a decision is expected before the end of the year.

Industry sources are reading the fund as a signal. One source working closely with the project told STV that Labour describing the fund as built on future oil and gas revenue suggests the government is "not bringing up the drawbridge" on more projects. That source also said the industry has started taking Burnham at face value when he talks about a pragmatic approach.

Opposition to Rosebank is organized. Fossil Free London and Uplift are campaigning to stop it. Labour MPs warned on Wednesday of major pushback inside the party if it is approved, and the Guardian reports they have discussed ways of forcing or encouraging a parliamentary vote. Ed Miliband, Fahnbulleh's mentor, once called Rosebank "climate vandalism," according to GB News.

On the other side, Conservative Chris Philp has called Labour's stance on Rosebank "madness," and Tories have urged Fahnbulleh to go further than Jackdaw.

Timing and a drilling setback

Rosebank was expected to start production early next year. STV reports that a very expensive piece of heavy equipment fell thousands of metres into the sea during drilling, stalling development somewhat. People in the industry told STV the mistake has not knocked the field off course.

The tax angle is a selling point inside Labour. A Labour source told STV that Jackdaw was the easier sell because the energy security, tax and climate arguments all pointed one way. On Rosebank, the source said, the key advantage would be tax revenue from the oil companies. STV also notes that Rosebank's longer production life is a plus for jobs and a minus for campaigners who want fossil fuel use ended.

The approvals so far have not changed the main driver. The government itself ties Jackdaw to the war in the Middle East and the energy crisis it has set off.

For the 122 people aboard the Petrojarl Rosebank, whether the vessel keeps working toward first oil next year or stands idle now rests with the energy secretary, the chancellor and a prime minister who has yet to say which way he leans.
