Global Marine is an established supplier to the oil and gas sector, providing a total subsea solution and subsea builds. For deep sea research, it supports scientists with cable route and installation services for ocean observatory projects where precision and difficult conditions matter. A distinctive part of the offering is its combination of specialized vessels, trenching assets, remotely operated vehicles, and engineering expertise. Its asset base takes in dedicated subsea installation vessels, cable maintenance and installation vessels, trenching systems, and cable working ROVs, all of them used to deliver projects around the world. A long track record in submarine telecommunications and the ability to handle demanding environments, including deep water and challenging routes such as Arctic and very deep-ocean installations, set the company further apart. OceanIQ and SubConnect form part of the broader group structure. OceanIQ provides data, survey, route engineering, permitting, and consultancy services. SubConnect offers specialist interconnectivity solutions and expertise in subsea cables and cable joints, covering design, testing, training, subsea housing, and inter-connectors. Taken together, the company combines marine contracting, technical consulting, asset-based delivery, and lifecycle support for subsea cable infrastructure across global markets, from the consultancy and route work that precedes a cable through to the maintenance and repair that keeps it running.
