What Intermarine UK does

Intermarine UK Limited is a privately held workforce solutions and project delivery company headquartered in Cardiff (registered), with primary operating presence in Pontypridd, Wales. It operates as the UK arm of Inter Marine Group, founded in 1989 in Poland by Slawomir T. Kalicki, and delivers skilled tradespeople, technical specialists, marine crews, and end-to-end work packages into shipbuilding, defence, marine, nuclear, offshore wind, and oil and gas programmes. Its service model spans labour supply on a contract/charge-out basis and managed turnkey delivery of discrete work scopes (sourcing, fabrication, installation, testing, commissioning). Under CEO Nick Mansell (appointed 2021) and Managing Director Ric Elkington, the company has consolidated activities under Intermarine UK Group Holdings and built a delivery network across the UK, Canada (Intermarine Canada Limited, July 2025), Singapore/Asia-Pacific (Intermarine APAC), Poland (Inter Marine Energy, IM Training), and a nuclear-specialist joint venture (Interweld Nuclear Services Ltd, ISO 19443 certified, formed 2021).

The company monetises through three primary streams: skilled workforce mobilisation under multi-year contract frameworks; turnkey project/work-package delivery on a deliverable basis; and marine crewing at daily/contract rates. Nuclear-grade materials and PPE supply is delivered through Interweld Nuclear Services Ltd. Customers are primarily large institutional buyers — the Royal Navy/UK Ministry of Defence (QEC, Type 26, Type 45, ongoing refits), EDF Energy (Hinkley Point C), Irving Shipbuilding/Seaspan/Davie under Canada's National Shipbuilding Strategy, the British Antarctic Survey, and Poland offshore wind developers — engaged via direct enterprise sales led by regional business development directors. Pricing is project-specific and negotiated; no public pricing exists.

The company has no proprietary technology stack or AI/ML capability. Its competitive moats are (i) a curated talent network of 20,000+ vetted professionals, (ii) security-clearance and nuclear-quality compliance infrastructure (ISO 19443, ASME NQA-1 alignment), (iii) a track record on landmark UK naval programmes that is difficult to replicate, and (iv) multi-jurisdictional immigration, welfare and compliance operations. Demonstrated scale includes 440+ workers on QEC, 550+ on Type 26 delivering 1 million+ hours per year, 100+ at peak on the ongoing Defence Vessel Refit, and 48 mariners on Hinkley Point C. Revenue and financials are not publicly disclosed.
