ACSM

What ACSM does

ACSM Shipping Co SL is a privately held Spanish subsea services company headquartered in Vigo, founded in 2001. It delivers integrated offshore solutions across the full life cycle of subsea assets — from pre-engineering assessment and route survey through installation, IMR (inspection, maintenance, and repair), and decommissioning — to clients in oil & gas, submarine cables (telecommunications and power), offshore renewables, oceanographic research, and salvage & rescue. The company reports 314 employees, operations across more than 60 countries, and a track record of more than 250 completed projects.

The company's operating platform is built on three owned DP2 offshore support vessels — OSV Genesis (90.20m, acquired 2025), OSV Nautilus (75m, acquired 2018 and upgraded in 2025 with a Kongsberg EM-124 full-depth multibeam echosounder), and OSV Artabro (90m, acquired 2021) — each permanently equipped with work-class ROVs and trenching systems. The ROV fleet of 20+ units spans ultra-heavy-duty (Triton XLX EVO II 200HP, 3,000m rated; CM-ROV 400HP for cable maintenance and burial) down to observation class. Supporting capabilities include multibeam and side-scan survey, 2D seismic, magnetometry, USBL/LBL positioning, subsea engineering, and third-party ROV asset management and refurbishment at the Naron ROV Base.

ACSM operates a B2B enterprise field-sales model, with no public pricing disclosed; revenue is generated through project-based and charter contracts with major oil operators, EPC contractors, telecom and power cable companies, and government/research institutes (e.g., Spanish Institute of Oceanography, SASEMAR). Revenue streams are organized around (i) subsea services and solutions, (ii) ROV and vessel charter/management, and (iii) asset management and technical services. Certifications include ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISM Code compliance. In 2025 the company received three ARDAN recognitions — Empresa Gacela, Empresa Generadora de Riqueza, and Empresa Global — from the Vigo Free Trade Zone Consortium, signaling sustained growth, value creation, and international expansion.

Broad incumbents

• Fugro: Global site characterisation, geophysical survey and subsea asset integrity specialist with much larger fleet and ROV capacity. Competes with ACSM on marine survey, geotechnical and offshore-wind site-investigation tenders across Europe and the Americas.
• Saipem: Italian tier-1 EPCI contractor with subsea pipelay, cable-lay and offshore-wind installation services. Competes with ACSM on large integrated offshore scopes, particularly in the Mediterranean and Middle East where ACSM operates.
• Oceaneering International: Global subsea robotics and intervention contractor with the world's largest owned WROV fleet. Competes directly with ACSM on oil & gas IMR, ROV operations and tooling supply, but at much greater scale and geographic breadth.
• Subsea 7: Global tier-1 subsea contractor delivering SURF, pipelay, IMR and renewables installation with a much larger fleet and balance sheet. Competes with ACSM for integrated scopes and on ROV/survey subcontracts, but operates at substantially bigger scale.

Direct peers

• DeepOcean: European subsea services company delivering survey, trenching, IMR and cable-lay support with owned vessels and ROVs. Directly matches ACSM's offshore wind, interconnector and submarine-cable value proposition across the North Sea and Atlantic basins.
• Helix Energy Solutions: Provider of subsea IMR, ROV intervention and offshore well services with owned OSVs and WROV systems. Comparable scope on oil & gas inspection, intervention and decommissioning work to ACSM's IMR and salvage verticals.
• DOF Subsea: Norway-based provider of subsea IMR, ROV and offshore vessel services to oil & gas, cables and offshore wind. Closely comparable business model to ACSM with owned/operated subsea vessels, WROV fleet and integrated campaign delivery.
• MMT Sweden: Specialist survey, geophysical and hydrographic services provider with owned vessels serving offshore wind, cables and oil & gas clients. Comparable capability mix to ACSM's survey-and-positioning offering, particularly on cable-route and offshore-wind site investigations.
• Global Marine Systems: Submarine cable installation, maintenance and burial specialist operating cable ships and WROVs. Directly comparable to ACSM's CM-ROV trenching, PLIB and cable-route survey capabilities on intercontinental and inter-island telecom and power-cable projects.

Emerging players

• ROVOP: Independent ROV operator supplying pilots, equipment and tooling to offshore energy, cable and survey clients. Comparable WROV operations and personnel-supply model to ACSM's offshore-personnel and asset-management services, but without ACSM's owned vessel fleet.
