Serica Energy has awarded Wood an engineering, procurement, construction and commissioning framework contract to support the life extension of the Bruce platform in the UK northern North Sea over a five-year period.

Wood’s services, managed by a multi-disciplinary team in Aberdeen and offshore, will help maintain production at the facility to 2030 and beyond, with further goals of improved operational efficiency and reliability.

The company has been assisting Serica Energy, most recently with bringing Bruce’s flare gas recovery system into operation.

Bruce field history

The Bruce field was discovered in 1974 and first produced in 1993. The original process/ utilities/quarters and drilling platforms went online during the early 1990s; a third jacket (the Western Area Development/Phase II) followed in 1998. The complex is now in its late 20s to early 30s. Serica took operatorship from bp in 2018. Under the previous operator, cessation of production had been expected around 2026. Serica has already pushed that outlook well into the 2030s and is talking about mid-2030s or later if infill drilling (first wells on Bruce since 2012, targeted from 2027) delivers.

The Wood five-year EPCC framework is the surface-side counterpart to that subsurface work: integrity, reliability, efficiency, and the kind of equipment upgrades that enable an aging platform keep running safely. The flare-gas recovery system Wood helped commission is part of the same package — both a regulatory/emissions item and a way to capture value that used to be flared.

North Sea context 

Most North Sea platforms were designed for a 20–30 year lifespan. The UK/Norwegian North Sea fleet now averages around 25 years, and a large share have already passed their original design life. Nine of the ten longest-standing fixed platforms in the world are in the North Sea. Ekofisk 2/4 B and 2/4 C (1974) and the Forties platforms (1975) are still operating more than 50 years after installation. Life extension is therefore the default, not the exception.

Operators drive platform life extensions because:

• New standalone platforms are rarely economic in a mature basin.
• Existing jackets, pipelines and export routes still have ullage.
• Infill wells, tiebacks and better reservoir management can add years of cash flow.
• Decommissioning a large complex is a multi-hundred-million-pound (sometimes billion-pound) project that companies prefer to postpone while the asset is still making money.

Platform life extension typically involves structural and fatigue reassessment, replacement of obsolete control and rotating equipment, corrosion and coating programmes, emissions projects, and updated safety cases. Regulators require demonstration that risk remains as low as reasonably practicable for the extended period.

Bruce is a good example of the current UKCS model: a mid-1990s hub that a smaller, more focused operator is treating as a long-lived production center rather than a sunset asset, using both subsurface work and a multi-year engineering contract to keep it going into the next decade.
