Seatrium Group

Seatrium Group is the operating brand of Seatrium Limited, a Singapore-headquartered offshore and marine engineering company created in 2023 through the combination of Sembcorp Marine and Keppel Offshore & Marine. The merger brought together two of Singapore's most established offshore and marine contractors, creating a group with a broad portfolio spanning offshore oil and gas platforms, floating production systems, offshore wind foundations and installation vessels, ship repair and conversion, and a growing range of low-carbon and renewable energy solutions. Seatrium is listed on the Singapore Exchange and is one of the largest offshore and marine engineering groups in the world by capacity and order book. The group's business is organised around design, engineering, procurement, construction, installation and commissioning of complex offshore and marine assets. Its yards and facilities are located in Singapore, Brazil, China, Indonesia, Norway, the United Kingdom and the United States, giving it a global footprint to serve oil majors, national oil companies, offshore wind developers and shipowners. Seatrium's product range includes jack-up and semi-submersible rigs, floating production storage and offloading (FPSO) vessels, floating storage and regasification units (FSRUs), offshore wind turbine installation vessels, and a variety of specialised vessels and conversions. Seatrium positions itself as a partner for the energy transition, with activities in offshore wind, hydrogen, carbon capture and storage, and other low-carbon technologies alongside its traditional oil and gas business. The company has a strong focus on research and development, digitalisation and sustainable shipyard operations. Its brand identity emphasises engineering excellence, safety, and the ability to deliver large, complex projects on a global scale. As a public company, Seatrium is owned by a broad base of shareholders, with Temasek-linked entities and institutional investors among its major shareholders. The group's leadership includes senior executives with deep experience in the offshore and marine sector. Seatrium continues to pursue new orders in both traditional and renewable energy markets, and its performance is closely tied to global energy investment cycles.

Seatrium Group was formed through the merger of Sembcorp Marine and Keppel Offshore & Marine, two of Singapore's oldest and most prominent offshore and marine engineering companies. The merger was announced in 2022 and completed in February 2023, creating a combined entity named Seatrium. The name 'Seatrium' is derived from 'sea' and 'atrium', reflecting a focus on the ocean and a collaborative, open approach. Sembcorp Marine traces its roots back to Jurong Shipyard, established in 1963, and grew into a major builder of offshore rigs and specialised vessels. Keppel Offshore & Marine, part of the Keppel Corporation, had a long history in ship repair, rig building and offshore engineering, with yards in Singapore and internationally. Both companies played key roles in Singapore's development as a global offshore and marine hub. The merger was driven by the need to create a larger, more competitive player in a consolidating global market, particularly as the offshore and marine industry faced cyclical downturns and a shift toward renewable energy. The combined group has a broad order book and a global footprint, with yards and offices in Singapore, Brazil, China, Indonesia, Norway, the UK and the US. Since its formation, Seatrium has focused on integrating operations, improving efficiency and pursuing opportunities in offshore wind, hydrogen and carbon capture. The company has also been active in ship repair and conversion, including projects for the cruise and defence sectors. In 2023, Seatrium began trading on the Singapore Exchange under the ticker S51. The group continues to invest in technology and sustainable solutions, positioning itself for the energy transition while maintaining its traditional oil and gas business.
