What OES Group does
OES Group designs, manufactures, and installs cathodic protection (CP) and marine anti-fouling systems for submerged steel structures in maritime, offshore wind, and ports & harbours environments. The company holds a distinctive position as the only manufacturer covering the full CP stack — both Impressed Current Cathodic Protection (ICCP) and Galvanic Anode Cathodic Protection (GACP) — alongside Marine Growth Prevention Systems (MGPS), Impressed Current Anti-Fouling (ICAF), and 23 kHz ultrasonic anti-fouling. It operates an integrated design-to-commissioning model: in-house CP modelling and engineering, an in-house foundry for aluminium sacrificial anodes (added in 2023), manufacturing of Switch Mode ICCP control units at Schiedam (Netherlands), and offshore installation and commissioning services.
The product line is anchored by proprietary ICCP innovations including the world's first ICCP Anode Cage (2020), the ICCP Anode Ring System (deployed at Arcadis Ost 1 and Nordsee Cluster B), the TiMMO Tube Anode for internal monopile protection, SCADA-controlled remote monitoring with 25–30 year design life, and the world's largest ICCP jacket system (Baltic Eagle OSS, saving 400+ tonnes of aluminium). Cumulative installations exceed 500 CP systems, 230+ ICCP systems, 1,000+ MGPS/ICAF systems, and 450,000+ sacrificial anodes. The company is certified to EN 15257 for CP personnel, ISO 9001, and ISO 1090.
OES Group generates revenue through bespoke, project-based contracts with enterprise buyers — primarily offshore wind developers (Iberdrola, RWE, Ocean Winds, EnBW, Parkwind, Northland Power/ORLEN, Shell/Eneco, EDF, Myeongwoon) and foundation fabricators (Smulders, Windar, Chantiers de l'Atlantique, Dajin Offshore, Navantia), with smaller recurring accounts in maritime (Svitzer) and ports (Peel Ports, PD Ports, Port of Rotterdam). Pricing is quote-based and multi-year, tied to design, manufacture, and installation of CP systems. Headcount sits in the 11–50 range, with production facilities in Gateshead (UK), Schiedam (Netherlands), and a Sharjah (UAE) regional office backed by a Dubai factory planned for 2026.

Products and services
- Impressed Current Cathodic Protection (ICCP) Systems Active corrosion protection systems using controlled DC power delivered through inert anodes, with reference electrodes for continuous monitoring and automatic adjustment, used to protect offshore wind foundations, vessels, and port structures over a 25-30+ year design life.
- Sacrificial Anodes High-quality aluminium, zinc, and magnesium sacrificial anodes that corrode preferentially to protect metal structures in marine environments; supplied in standard and custom fabricated formats to vessels, harbour operators, and offshore contractors.
- MGPS & ICAF Systems (Marine Growth Prevention Systems / Impressed Current Anti-Fouling) Systems that use low-level electrical currents to release copper and aluminium ions into seawater, preventing marine organism attachment on cooling systems, pipework, and submerged surfaces.
- Ultrasonic Anti-Fouling Systems Chemical-free anti-fouling technology using high-frequency sound waves at a core frequency of 23 kHz to prevent marine organism build-up on vessel hulls, propulsion gear, heat exchangers, and submerged surfaces.

OES Group competitors and assessment
Company assessmentBroad incumbents
- AkzoNobel (International Paint): Global marine coatings giant (Intersleek, International Paint brands) supplying anti-fouling hull coatings and offshore structure protection to shipowners and offshore wind developers. Broad incumbent in marine corrosion/fouling protection with overlapping but coating-focused offerings.
- Corrpro Companies (Aegion): One of the largest North American cathodic protection service providers under the Aegion Corporation umbrella. Comparable in CP engineering and installation services but operates at significantly greater scale across multiple infrastructure end-markets beyond offshore wind.
- Hempel: Global marine coatings and anti-fouling paint manufacturer serving shipbuilders, shipowners, and offshore operators. Adjacent competitor to OES Group in marine anti-fouling, though focused on coatings rather than ICCP/GACP electrical protection.
Direct peers
- Vector Corrosion Technologies: Canadian-headquartered corrosion engineering firm offering ICCP and galvanic cathodic protection systems, with significant offshore wind exposure. Closely comparable service model and customer base to OES Group in offshore wind foundation protection.
- BAC Corrosion Control: UK-based specialist cathodic protection contractor offering ICCP/GACP design, supply, installation, and monitoring for offshore wind, ports, and industrial infrastructure. Direct peer with overlapping customer base in UK and European offshore wind.
- Deepwater Corrosion Services: Houston-based cathodic protection services and product supplier for offshore oil & gas, marine, and offshore wind sectors. Directly comparable to OES Group in ICCP design, installation, and anode manufacturing for subsea and splash-zone protection.
- Cathelco: UK-based manufacturer of MGPS (Marine Growth Prevention Systems) and ICCP/ICAF systems for ships and offshore structures. Directly comparable product portfolio to OES Group's anti-fouling and cathodic protection lines, serving overlapping maritime and offshore customers.
- Cathodic Protection Co Ltd (CP Co): UK-based specialist cathodic protection contractor offering ICCP, GACP, and CP monitoring services for offshore, marine, and infrastructure clients. Direct competitor to OES Group in the UK offshore wind and ports & harbours markets.
Emerging players
- Elsyca: Belgian engineering firm specializing in computational CP design, simulation, and monitoring software. Complementary to OES Group's CP design capabilities, with overlapping offshore wind and marine customer base, though primarily a software/services business rather than a manufacturer.
Regional players
- Imenco: Norwegian supplier of subsea cameras, lights, and cathodic protection monitoring equipment for offshore and aquaculture markets. Comparable in subsea CP and marine anti-fouling technologies, with Norwegian offshore oil & gas and offshore wind exposure that overlaps OES Group's customer type.
