EMAS operates as the offshore contracting and operating brand of Ezra Holdings, providing integrated offshore and subsea solutions to the global oil and gas industry. Founded in 1992 in Singapore, the group has expanded from managing offshore support vessels in the Asia Pacific maritime sector to a diversified seabed‑to‑surface engineering, construction, marine and production services provider with a presence across multiple continents, including offices in Singapore, Oslo and Houston. In 2003 EMAS listed on the Singapore Exchange and was promoted to the Mainboard in 2005. For 2012, it reported revenue of US$984.2 million and net income of US$186.2 million, with around 5,500 employees.
The organisation is structured around four main business segments. EMAS AMC is the subsea construction and EPCI division, delivering design, construction, transportation and field installation work, including subsea construction, SURF and pipelay projects, FPSO and floater installations, IMR services, floatovers and decommissioning, with reference projects for clients such as BP and Chevron in the Gulf of Mexico and Gulf of Thailand. EMAS Energy provides integrated onshore and offshore well intervention and drilling services, including workover, drilling, fluid pumping, nitrogen, pipeline and process services. EMAS Marine manages and operates a young, versatile fleet of anchor handling, towing and supply vessels, anchor‑handling tugs, platform supply vessels and fast crew boats that support offshore operations throughout the oilfield life cycle. EMAS Production, largely held through EOC Limited, owns and operates FPSO facilities and provides FPSO conversion management, operations and maintenance, and the design and provision of mooring, riser and turret systems.
Supporting these service lines, EMAS also operates fabrication, construction, engineering and logistics facilities in Vietnam (Ho Chi Minh City and Vung Tau), Norway (Hinna) and Houston, enabling offshore fabrication and project support for regional and international oil and gas developments. The group has expanded through strategic acquisitions, notably Aker Marine Contractors in 2011, and has undertaken projects in emerging offshore markets including Brazil, while at times facing financial restructuring challenges, including suspension of trading of its Singapore‑listed shares in 2017.
