Oil & Gas
Oil and gas engineering in the UK is operating in a sector that’s contracting at pace. Production from the UK Continental Shelf sits at roughly 20% of its 1999 peak, the government has ended new exploration licensing, and the NSTA projects an 89% fall in output by 2050. None of that makes the engineering easier. At Morson Praxis, we work with operators and Tier 1 contractors who need technical support across the productive life of existing assets and what comes after.

What sets us apart in oil and gas engineering
Our engineers have worked across upstream, midstream and downstream oil and gas environments, from FEED studies and detailed design through to integrity management and operational support. We know how North Sea topsides age. We know how onshore terminals get pushed past their original design basis. And we know where risk accumulates when investment slows and inspection intervals stretch.
Around 115,000 UK jobs depend on infrastructure that’s been in service for 30 or 40 years. Most of that infrastructure needs sustained technical attention, not periodic review. We’re not consultants who tell clients what they want to hear: if an assessment points somewhere uncomfortable, that’s what we document. Clients tend to find that more useful than confident reassurance.
Upstream and offshore
Engineering for the North Sea's mature basin
The UKCS is a mature basin. Most production now comes from smaller, technically complex fields where engineering margins are tighter and the cost of errors is higher. We support operators through FEED studies, detailed structural and process design, and integrity assessment for ageing assets. Where tiebacks to existing infrastructure are viable under the government’s Transitional Energy Certificate framework, we can help evaluate and execute them.
Asset life extension
Keeping ageing infrastructure productive and safe
When an asset has been in service for 30 years or more, the original design assumptions rarely hold. We carry out fitness-for-purpose assessments, corrosion management reviews and structural integrity analysis to establish what’s viable and at what cost. That assessment is grounded in inspection data and engineering judgement rather than commercial optimism, so clients have something real to base their decisions on.
Digital engineering
Accurate data when the drawings don't tell the whole story
On oil and gas projects, we use digital capture and 3D modelling as standard. Laser scanning, PDMS modelling and digital twin development give operators an accurate, current picture of their assets that paper records can’t provide. It matters most on congested topsides or brownfield scopes where as-built drawings haven’t kept pace with what’s actually on site.

Understanding oil and gas engineering
Oil and gas engineering frequently asked questions (FAQs).
Oil and gas engineering is the technical discipline that covers the design, construction, operation and decommissioning of upstream, midstream and downstream energy assets. It spans structural and process engineering for offshore platforms, pipeline systems, onshore processing terminals and storage facilities. In the UK, it increasingly overlaps with the transition from conventional hydrocarbon production to lower-carbon energy systems.
An offshore engineering consultancy is a specialist firm that provides technical support across the design, integrity management and decommissioning of offshore oil and gas assets. That typically includes FEED studies, structural analysis, process engineering, HAZOP facilitation and risk-based inspection planning. In mature basins like the UKCS, consultancies also advise operators on life extension decisions and regulatory compliance.
A reliable oil and gas consultancy in the UK is one with demonstrable experience across the full asset lifecycle, not just individual disciplines. The most useful indicator is whether they’ve worked in both offshore and onshore environments, know the NSTA regulatory framework, and have a track record of giving clients clear assessments rather than commercially convenient ones.
FEED is front-end engineering and design: the project phase that defines technical scope, cost estimate and execution plan before detailed design begins. It’s where decisions on process configuration, equipment selection and safety strategy get made. A well-executed FEED reduces costly late-stage changes and gives operators a reliable basis for investment decisions.
Asset life extension on the North Sea typically requires fitness-for-purpose assessments, corrosion management reviews, structural integrity analysis and updated safety cases. Operators also need risk-based inspection planning aligned with API 580 and 581 standards. For ageing topsides, modifications to accommodate changed process conditions or regulatory requirements are common, each needing detailed engineering and documented change control.
