Global Marine Group is a UK‑headquartered subsea cable solutions provider focused on the global telecommunications, offshore wind and utility markets. With a heritage dating back to 1850 and the first undersea telegraph cables between the UK and France, the company has evolved through joint ventures, acquisitions and restructurings to become one of the world’s largest independent providers of subsea cable installation, maintenance and repair services. It delivers mission‑critical support to the global subsea fibre‑optic network and related power and sensing systems, maintaining roughly 31% of global maintained cable length through long‑term maintenance zone and charter agreements with telecommunications carriers, hyperscalers, utilities and equipment suppliers. A substantial share of its revenue is backed by multi‑year take‑or‑pay and long‑term contracts, providing predictable utilisation of its assets.
Operationally, Global Marine Group owns and operates a fleet of six specialised vessels equipped for cable installation, repair and maintenance, together with depots and facilities in the UK and internationally. Its business is structured around lifecycle services that span pre‑installation consultancy, desktop studies, survey and route engineering, permitting, cable installation, trenching and burial, storage of spare cables, fault location, recovery and repair. Within the Group, the Global Marine business unit focuses on subsea fibre‑optic cable installation and maintenance for the telecoms and oil & gas sectors; OceanIQ provides subsea cable data, route engineering and advisory services for telecom and power cable projects; and SubConnect designs and supplies subsea jointing and interconnectivity solutions, including Universal Joint products, testing, training and qualification. The company underpins these activities with ISO‑certified quality, environmental and health and safety management systems and corporate policies aimed at protecting people and the marine environment while supporting long‑term connectivity infrastructure worldwide.
