What Dorman Long Engineering does

Dorman Long Engineering Limited (DLE) is a Lagos-headquartered EPC, steel fabrication, hot-dip galvanizing, and asset management company serving primarily Nigeria's oil and gas industry, alongside power, telecommunications, manufacturing, and infrastructure customers. Founded circa 1948 and operating from three production yards in Lagos — the historical head office at Idi-Oro with light/heavy assembly workshops, the Agege galvanizing plant, and a waterfront facility at the Nigerian Naval Dockyard with direct jetty access for heavy modular integration — DLE delivers engineering, procurement, fabrication, construction, and installation services for pressure vessels, offshore platforms, storage tanks, pipe spools, marine structures, manifold skids, and modular assemblies. In 2009 the company installed Nigeria/West Africa's first heavy-engineering-quality large-scale hot-dip galvanizing facility with 90,000 MT/annum capacity (14m × 1.5m × 2.4m galvanizing kettle, 350 MT molten zinc holding, 4 × 195,000 BTU/hr dual-fuel burners) at Agege, supporting power transmission tower, grating, and highway guard-rail corrosion protection work.

Revenue mechanics are project-based EPC contracts (one-time project fees), transaction-based galvanizing services (per-tonne processing of customer-supplied or DLE-procured steel), recurring asset management and maintenance work (FPSO shutdowns, integrity recertification, field service operations), and procurement/logistics margin on equipment sourced from OEM partners including Rockwell Automation, L&T, Mustang Engineering, William Hare, Posco Plantec, Wilson USA, Galperti, WESCO, Distribution Now, Hindustan Zinc, and ArcelorMittal. Go-to-market is direct enterprise sales to IOC customers — Chevron Nigeria, ExxonMobil (MPN Unlimited), TotalEnergies Nigeria, NNPC, Shell/SDC, NAOC, SNEPCO, First E&P, Addax, Daewoo — and selected industrial buyers (Nestlé Nigeria), supplemented by an Authorized Distributor relationship with Rockwell Automation in Nigeria and active participation in industry events (SAIPEC, NIES, OTC, Welding Federation Conference). Pricing is quote-based on project scope; no published pricing tiers exist. Engineering design relies on conventional CAD/FEA (Autodesk Revit 2019, Autodesk Robot, Tekla Structures, Autodesk Plant 3D 2019, PV Elite, Compress) rather than proprietary AI tooling. Certifications underpinning contract eligibility are ISO 9001:2015 (SGS/UKAS, since 2006), ASME U/U2/PP/S/R stamps for pressure vessels, power piping, power boilers and repairs, SON-MANCAP, NCEC Nigerian Content Equipment Certificates, NNRA Act 1995 compliance, and a recorded 6 million Lost Time Injury-free man-hours HSE record.

Ownership is private. Africa Capitalworks acquired a minority stake in September 2021 with stated intent to fund site expansion and service-line broadening, and now holds a non-executive board seat via Deal Executive Grégoire Fredet. The board is chaired by Dr. Timi Austen-Peters (financial services lawyer; former UN Geneva and African Development Bank) with Engr. Chris Ijeli (31+ years O&G EPC experience; University of Benin B.Eng/M.Eng; alumnus of Georgia Institute of Technology and Lagos Business School) as Managing Director/CEO; other directors include Cecilia Akintomide (former AfDB Vice President Secretary General; Ecobank adviser), Dr. Babajide Agunbiade (former GE/NOV executive; subsea SME), Nana Sao (ex-Goldman Sachs/DMC Partners), and Abubakar Sule Katagum (MD of Bauchi Investment Corporation). The firm operates with 101-250 employees, a 13-person QA/QC team, and an 11-person NEBOSH/OSHA/MNISP-certified HSE unit, and self-positions as West Africa's #1 steel fabrication and galvanizing company with a stated vision to lead EPC services across Sub-Saharan Africa.
