Subsea7

Subsea7 S.A. is a Luxembourg‑incorporated, London‑headquartered subsea engineering, construction and services company that delivers offshore projects for the global energy industry. Originating from the 2011 combination of Subsea 7 Inc. and Acergy S.A., it operates worldwide across oil and gas and renewable energy markets, executing complex seabed‑to‑surface developments in deep and shallow waters. The group structures its activities primarily through two operational business units, Subsea and Conventional, and Renewables and Emerging Energies, supported by corporate and autonomous subsidiaries including Seaway7, Xodus and 4Subsea. The Subsea and Conventional business provides engineering, procurement, construction, installation and commissioning of subsea umbilicals, risers and flowlines (SURF), long‑term pipeline‑lay support in Brazil, and conventional fabrication, installation, extension and refurbishment of fixed and floating platforms and associated pipelines in shallow water. It also delivers inspection, repair and maintenance, integrity management, remote intervention, heavy lifting, decommissioning of offshore structures and supports carbon capture, utilisation and storage initiatives. The Renewables business, operating largely under the Seaway7 brand, focuses on fixed and floating offshore wind, including procurement and installation of foundations, inner‑array cables, wind turbines, offshore substations and heavy transportation. These services are underpinned by a large, specialised fleet of rigid pipelay and heavy‑lift vessels, construction and flex‑lay ships, diving support and IMR vessels, and dedicated renewables and heavy transport assets. Strategically, Subsea7 positions itself as a provider of offshore energy transition solutions, enabling lower‑carbon oil and gas developments and large‑scale offshore wind. In 2024 it reported revenue of US$6.8 billion and EBITDA of US$1,090 million, driven by late‑cycle recovery in subsea markets and structural growth in offshore wind. Its sustainability programme targets 35 GW of cumulative renewables capacity supported by 2030, a 50% reduction in Scope 1 and 2 greenhouse gas emissions by 2035 from a 2018 baseline, and net‑zero Scope 1 and 2 emissions by 2050, supported by investment in a relatively young, low‑sulphur‑fuelled fleet, hybridisation initiatives and broader climate‑aligned governance and reporting.
