What TMC does

TMC Compressors AS is a privately held Norwegian manufacturer that designs, builds, and services compressed air systems exclusively for marine and offshore applications. Founded in 1989 and headquartered in Oslo, the company specializes in screw air compressors, boil-off gas (BOG) compressors for LNG carriers, air lubrication system (ALS) compressors for hull friction reduction, plus complementary air dryers and filtration equipment. TMC positions its technology as purpose-built for marine environments rather than marinized land-based compressors; key proprietary innovations include a patented Thermal Mixing Valve (TMV) that prevents condensation, a patented three-stage oil separation system, and Smart Air frequency-controlled compressors that deliver up to 50% energy savings versus fixed-speed units. The company has supplied more than 20,000 compressors worldwide and holds ISO 9001, 14001, 45001, and 27001 certifications.

TMC generates revenue through direct enterprise sales of complete compressed air system packages to shipbuilders (e.g., Hyundai Heavy Industries, Samsung Heavy Industries, Daewoo Shipbuilding, Hudong-Zhonghua) and ship owners/operators (e.g., Maran Gas Maritime, MOL, Golar LNG, CMA CGM, MODEC, Yinson, Van Oord), supplemented by a global aftermarket business comprising spare parts, 24/7 technical support, and condition monitoring. Pricing is project-based and negotiated per vessel; contract values are not publicly disclosed. The company maintains wholly owned subsidiaries in China, Singapore, and Korea to serve the dominant Asia-Pacific shipbuilding hubs, and operates spare parts stock points in Oslo, Singapore, Dubai, and Houston. A 2019 strategic cooperation agreement with Sauer Compressors extends TMC's scope of supply into high-pressure piston compressors, enabling complete marine air packages per vessel.
