What Wilton Engineering does

Wilton Engineering Services Limited is a UK-based, privately-held engineering services company founded in 1994 by Bill Scott and Steve Glenn, headquartered at the Port Clarence Offshore Base on the River Tees in Middlesbrough. The company specialises in the design, fabrication, blasting, coating, and loadout of large, complex modular steel structures for the offshore oil & gas, offshore wind / renewables, defence, subsea, and decommissioning end-markets. Core technical capabilities include in-house structural, mechanical, and civil engineering design (FEED studies, complex structural analysis, finite element analysis, 3D visualisation, and design for manufacture), advanced welding to ISO 3834-2, structural steelwork execution to BS EN 1090-2 Execution Class 4, and an 11,500 sqm blast and coatings facility with humidity-controlled painting halls. Operations run from a combined 113-acre site comprising the original 54-acre Port Clarence base and the adjacent 58-acre Haverton Hill facility acquired from EEW OSB in 2021, featuring 7 quays, 5 slipways, four large construction halls, and 1,100te tandem lift capability with direct marine loadout to the North Sea.

The company's go-to-market is enterprise field sales targeting tier-1 energy operators, offshore wind developers, defence primes, and subsea contractors, supported by a dedicated commercial and tendering team that manages projects from initial inquiry through execution. Revenue is generated through bespoke project-based contracts (Fabrication Services), protective coatings (via group company Universal Coatings & Services, now 60% owned by Denholm Industrial Services), and ancillary facility rental and logistics income (via Port Clarence Logistics Ltd). Named enterprise customers include Ørsted and Steelwind in offshore wind (notably 21 transition pieces for Hornsea Project One) and Chevron, Saipem, Subsea 7, Technip, and Talisman/Repsol in oil & gas. Wilton reported turnover of £23.25m and profit after tax of £2.08m for FY2022-23, with a £24m forward order book by October 2023.

Wilton holds ISO 9001, ISO 14001, ISO 45001, ISO 3834-2, and BS EN 1090-2 certifications and has historically delivered approximately 50% of all North Sea topside modules and over 300,000 tonnes of modular topsides. The company maintains a structured Apprenticeship Academy (45 apprentices as of October 2025) in partnership with Hartlepool College and Teesside University, and co-founded the UK's first Renewable Academy in 2021. Sister companies Universal Coatings & Services and PC Logistics extend the offering into coatings and site/quay management, while tenants such as Protium (40MW green hydrogen), Stobart Energy, Jackson Hogg, and Last Mile Logistics diversify site economics beyond Wilton's own fabrication activity.
