Cathwell

What Cathwell does

Cathwell AS is a privately owned Norwegian industrial manufacturer founded in 2003 and headquartered in Langesund, Norway, that designs and produces cathodic protection and marine antifouling systems for maritime, offshore energy, and land-based infrastructure customers. The company's technology stack centers on two proprietary control panel platforms: CathFlow for Marine Growth Prevention Systems / Impressed Current Antifouling (MGPS/ICAF) and CathSense for Impressed Current Cathodic Protection (ICCP). Both platforms are modular, with PowerFlow and PowerSense power-output modules that interconnect to scale capacity up to 3200W per stack, and a shared Controller C100 mk II operator interface supporting Ethernet, HTTP/JSON, Modbus TCP/IP, RS485, and USB connectivity for remote monitoring. Surrounding the control electronics is a broad hardware portfolio: MMO/Ti ICCP disc anodes in multiple diameters, fully recessed zinc reference cells with rated 10-year lifespan and ±30mV accuracy, copper/iron/aluminium MGPS/ICAF anodes, sacrificial aluminium and environmental zinc (Eco-Anode) anodes conforming to DNVGL-RP-B401, and silver-graphite shaft grounding arrangements with split-ring or band designs.

The company operates a sales-led B2B go-to-market targeting enterprise customers including ship operators, floating offshore unit operators, offshore wind turbine operators, harbour authorities, and pipeline/storage tank/sea cable/foundation owners across more than 50 countries. Revenue derives from hardware product sales priced upon inquiry via a direct e-commerce storefront, paired with technical services in inspection, engineering, and consultancy. Cathwell holds DNV-granted ICCP type approval, ISO 9001, ISO 45001, Lloyd's Register and RMRS recognition for the Marathon IQ2 anode shield, and corporate membership in AMPP, supplying regulatory-grade procurement eligibility that constitutes a meaningful portion of its go-to-market. Headcount is reported in the 20-50 employee band under the Norwegian Transparency Act, and the company carries no disclosed institutional investors, funding events, or acquisitions.

Core offering

Cathwell designs and manufactures cathodic protection and antifouling systems for maritime, offshore, and land-based industries. Its portfolio includes ICCP and MGPS/ICAF modular control panels (CathFlow®, CathSense®), MMO/Ti disc anodes, zinc reference cells, copper/iron/aluminium antifouling anodes, aluminium and environmental zinc sacrificial anodes, shaft grounding arrangements, and related chemicals. The company also provides technical inspection, engineering, and consultancy services alongside product sales, serving ship operators, floating offshore unit operators, wind turbine operators, harbours, pipelines, storage tanks, sea cables, and foundations globally.

Product overview

Cathwell provides a comprehensive portfolio of cathodic protection and antifouling solutions for maritime, offshore, and land-based industries. The product ecosystem centers on two main control panel platforms: CathFlow® for MGPS/ICAF systems and CathSense® for ICCP systems, both modular and expandable. Supporting these are ICCP components (disc anodes like ADS-1, ADS-3, CWC with MMO/Ti construction; zinc reference cells like RSH), MGPS/ICAF anodes (copper, iron, and aluminium variants in various sizes), sacrificial anodes (aluminium anodes conforming to DNVGL-RP-B401 in various weights; environmental cadmium-free zinc anodes), and shaft grounding systems (silver split ring and silver band arrangements with brushes and holders). Chemical products include Marathon IQ2 epoxy anode shields and V-5200 acid-free vaseline. The portfolio serves diverse sectors including ships, floating offshore units, wind turbines, harbours, pipelines, storage tanks, sea cables, and foundations.

Direct peers

• Tetracore Group: Norwegian cathodic protection and corrosion consultancy providing CP design, inspection, and anode supply. Geographic and technical peer overlapping with Cathwell's Scandinavian offshore wind and pipeline service footprint.
• MATCOR: US-based cathodic protection specialist offering ICCP systems, sacrificial anodes, and engineering services for infrastructure, marine, and oil & gas. Comparable engineered-product portfolio to Cathwell's ICCP and anode lines for land-based and offshore applications.
• Cathelco: UK-based specialist in marine cathodic protection and antifouling systems for ships and offshore structures. Direct overlap with Cathwell in ICCP, MGPS/ICAF, and shaft grounding product categories serving the same shipping and offshore customer base.
• Corrpro Companies: Specialist provider of cathodic protection engineering, products, and services for pipelines, storage tanks, and marine structures. Cathwell's land-based pipeline, tank, and harbour segments overlap directly with Corrpro's core offerings.
• Imenco: Norwegian subsea and marine technology supplier with cathodic protection products alongside subsea cameras and aquaculture systems. Relevant Nordic regional peer with overlapping ICCP and corrosion mitigation offerings for offshore customers.
• Deepwater Corrosion Services: Offshore cathodic protection specialist focused on subsea inspection, retrofit CP systems, and anode manufacturing. Comparable offshore customer base and ICCP + sacrificial anode product mix as Cathwell.

Broad incumbents

• Hempel Marine: Large marine and protective coatings supplier competing with Cathwell's antifouling offerings through fouling-release and biocide hull coatings. Addresses the same biofouling problem via a coatings rather than electrochemical-systems route.
• Aegion Corporation: Diversified infrastructure protection company operating cathodic protection services (including Corrpro) alongside pipeline rehabilitation and energy services. Much larger incumbent with overlapping cathodic protection capabilities but a much broader portfolio.
• Nippon Paint Marine (International Paint): Global marine coatings major offering antifouling hull coatings as an alternative to Cathwell's MGPS/ICAF systems. Competes indirectly on marine biofouling prevention across newbuild and dry-dock markets worldwide.

Emerging players

• Subsea Industries / Ecospeed (HullFrog): Specialist in hull cleanliness solutions (Ecospeed coating, hard hull coating systems) as an alternative fouling-prevention offering to Cathwell's MGPS/ICAF systems. Closely adjacent niche player in marine fouling prevention.
