ADAMS

What ADAMS does

ADAMS (legal name Khalifa A. Algosaibi Diving & Marine Services Company) is a Saudi Arabia-based subsea services company founded in 1964 in Dammam as the first subsea contractor in the Kingdom. Originally formed to serve Saudi ARAMCO, the company provides subsea construction, maintenance, inspection, and repair services to major international oil companies, national oil companies, offshore construction contractors, and naval clients. Its core offering spans air, mixed gas, and saturation diving; underwater repair and construction (steel repairs, concrete placement, hyperbaric and wet welding, hydraulic and BROCO cutting, core drilling); ROV and AUV-based inspection; submarine cable repair and testing; and SPM support for naval and shipyard infrastructure.

The company's underlying technology platform is built around a fleet of owned dynamic positioning (DP) vessels — ADAMS Challenge, ADAMS Nomad, ADAMS Surveyor, ADAMS Arrow, ADAMS Aquanaut, and ADAMS Vision — supplemented by dedicated diving support vessels Algosaibi 51 and Algosaibi 42. Supporting assets include air and saturation dive spreads, decompression chambers, diving compressors, subsea tooling, NDT equipment, and TV/video survey systems. The workforce is structured around IMCA-certified divers with 50m offshore air diving qualifications and a crew supply network of certified agencies across Latvia, Ukraine, the Baltic States, Indonesia, and the Philippines. ADAMS is ISO 9001:2015 certified, MLC 2006 certified, an IMCA member, and ABS audited.

ADAMS generates revenue through project-based professional services engagements, multi-year contracts with oil and gas majors and offshore construction contractors, vessel chartering (in which ADAMS Chartering acts as exclusive broker of the fleet), and crew supply services to ship owners and managers. The go-to-market is direct enterprise field sales targeting major oil companies (Saudi ARAMCO, Shell, BP, Statoil, Norsk Hydro, Pemex) and offshore contractors (McDermott, Halliburton), with services delivered globally across the North Sea, Gulf of Mexico, Far Eastern Waters, West Africa, Middle East, and Australian Continental Shelf. The company operates as part of the GOC Khalifa A. Algosaibi family of companies, with related subsidiaries ADAMS Offshore WLL (AOWLL) handling international deep-water operations and ADAMS Technical Services (ATS) providing integrated technical offerings.

Broad incumbents

• TechnipFMC: Integrated subsea production systems and EPCI contractor. Comparable in subsea engineering, construction, and IRM services for offshore oil & gas, but operates at materially larger scale across both hardware and services.
• McDermott International: Major offshore EPC contractor and ADAMS customer for DP vessel support. Operates in the same subsea construction market ADAMS supports, with comparable service lines but at much larger scale.
• Saipem: Global engineering and construction major with large offshore EPCI and subsea services business. Comparable in subsea construction and diving support for major offshore projects, but vastly broader portfolio including drilling, onshore, and renewables.

Emerging players

• Fugro: Global geo-data specialist using subsea ROVs, AUVs, and survey vessels for site characterization, pipeline inspection, and offshore wind surveys. Comparable in ROV/AUV-based subsea inspection and survey capabilities.

Direct peers
