Helix Energy Solutions Group
Provides rigless **subsea well intervention** and offshore well management services, including campaign-based intervention and late-life well work.
Helix Energy Solutions Group is an international offshore energy services company providing specialty services to the offshore energy industry, with a focus on well intervention, robotics, and full-field decommissioning operations. Its work supports the energy transition by helping maximize production from remaining oil and gas reserves, by decommissioning end-of-life oil and gas fields, and by supporting renewable energy developments. Its services reach both oil and gas and renewable energy markets, with activity concentrated in the Gulf of America, U.S. East Coast, Brazil, North Sea, Asia Pacific, and West Africa regions. The scope of the business is broad and takes in drilling support, reservoir management, life of field services, inspection, repair and maintenance, saturation diving, well intervention, and offshore renewable energy. Within well intervention, Helix covers subsea hydraulic well intervention, subsea mechanical well intervention, and subsea well integrity. For offshore renewable energy, it covers seabed clearance and subsea construction, subsea trenching solutions, and explosive ordnance disposal services. Subsea Technologies Group Ltd (STL) forms part of what the company does. Helix backs these services with assets and operational capabilities that include riser-based well intervention, riserless well intervention, subsea robotics, ROVs and trenching, and subsea construction. Its marine support assets take in liftboats, crewboats, offshore supply vessels, diving support vessels, and a heavy lift derrick barge. In how it works, Helix tailors support to project needs and helps customers overcome offshore challenges in a cost-effective way. A notable part of the offering is the Subsea Services Alliance, an integrated approach to subsea well services that combines the capabilities of Helix and Schlumberger. The alliance brings together surface, subsea, and subsurface capabilities along with technologies, digital tools, subsea reservoir performance services, and production chemistry. It delivers integrated subsea intervention and decommissioning solutions built to maximize economic recovery, reduce costs, and enhance safety. The alliance further supports well construction, completion and abandonment options for deep and ultra-deepwater basins and high-pressure, high-temperature environments, as well as subsea well access, remediation, and intervention tooling.
