What TGE Marine does

TGE Marine Gas Engineering GmbH is a Bonn-headquartered German engineering company founded in 1980 and wholly owned by Tokyo-based Mitsui E&S Marine Propulsion System Division. The firm specializes in the design and engineering of cargo handling systems, fuel gas systems, and Type C storage tanks for cryogenic and liquefied gases including LNG, LPG, ammonia, ethylene, and CO2. Operating under an EPCS (Engineering, Procurement, Construction, Supervision) contract model, the company has delivered more than 250 gas carriers, 400+ Type C tanks, 100+ fuel gas systems, and 160+ ammonia-capable gas carriers across its 45+ year history.

The technology portfolio centers on proprietary cryogenic gas handling and storage, with the RECONOMISER registered patent for Boil-Off Gas treatment on high-pressure MAN ME-GI dual-fuel engines as the flagship sub-product. Engineering specializations include the world's largest cylindrical Type C tanks at 14,000 m³ each on the Torman FSRU and specially developed liquid CO2 cargo handling systems engineered to manage vapor return and cross-contamination risks inherent to CCS shipping. The product portfolio is organized into six core lines: Fuel Gas Systems, Gas Carrier Systems, Ammonia Systems, Bunker Vessel Systems, Floating Unit Systems, and CO2 Carrier Systems, all served by a 24/7 lifetime service and spare-parts offering covering warranty management, dry-docking supervision, retrofits, crew training, and remote monitoring.

TGE Marine operates a B2B enterprise field-sales motion, securing direct EPCS contracts with ship owners and shipyards through long-cycle project engagements spanning ship design through commissioning. Distribution combines direct contracting with the Mitsui E&S parent platform, regional agent networks (notably SEA POWER LTD), and a wholly-owned Shanghai regional subsidiary serving the Asia-Pacific shipbuilding market. The primary customer segments are ship owners/operators, shipbuilders, CCS project developers (including the flagship Northern Lights JV with Shell/Total/Equinor), and floating-unit operators. The firm is privately held, with revenue not publicly disclosed, and no funding rounds or external institutional investors are reported.

Core offering

TGE Marine Gas Engineering provides engineered cargo handling systems, Type C storage tanks, and fuel gas supply systems for liquefied gas carriers, bunker vessels, and floating units (FSRU, FRU, FSU, FLNG). The company delivers these systems under EPCS (Engineering, Procurement, Construction, Supervision) contracts for LNG, LPG, ammonia, ethane/ethylene, and CO2 applications, and supports them with a 24/7 after-sales service offering for the full vessel lifecycle.

Product overview

TGE Marine Gas Engineering is the leading provider of liquefied gas systems, operating under an EPCS (Engineering, Procurement, Construction, Supervision) model. The product portfolio comprises six interconnected core systems: Fuel Gas Systems (FGS) for LNG, ammonia, LPG, and ethane propulsion; Gas Carrier Systems for IGC-code compliant transport of cryogenic gases; Ammonia Systems covering both cargo handling and fuel gas supply; Bunker Vessel Systems for LNG and alternative fuel supply ships; Floating Unit Systems for FSRU, FRU, FSU, and FLNG applications; and CO₂ Carrier Systems for liquid CO₂ transportation supporting CCS projects. A key proprietary sub-product is the RECONOMISER™ for boil-off gas management on ME-GI engines. All systems are supported by a dedicated 24/7 Service & Support offering covering the full vessel lifecycle.

Scale indicators8 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• MAN Energy Solutions: MAN is the OEM of the ME-GI dual-fuel engine platform that RECONOMISER is built around. While not a direct competitor in cargo containment, MAN's installed engine base defines the addressable market for TGE's fuel-gas systems and BOG IP.
• Mitsubishi Heavy Industries: MHI is a major LNG carrier builder and supplier of MOSS spherical cargo containment systems. Its shipbuilding and cryogenic tank businesses overlap with TGE's gas carrier systems engineering work for large newbuilds.
• Wärtsilä: Wärtsilä is a broad marine energy systems incumbent offering integrated dual-fuel engines and gas handling solutions, competing with TGE in fuel-gas supply systems and increasingly offering packaged alternatives to TGE's bolt-on EPCS model.
• Kawasaki Heavy Industries: Kawasaki supplies LNG carrier cargo containment systems (also MOSS-type) and cryogenic process packages, competing with TGE in the gas carrier engineering segment and adjacent LNG/CO2 handling applications.
• Linde Engineering: Linde Engineering provides industrial-scale cryogenic and gas-handling plant engineering with maritime adjacencies. It is a broader competitor than TGE in the cryogenic engineering talent and systems market.

Direct peers

• Chart Industries: Chart provides cryogenic equipment, tanks and process systems for LNG, LPG, ammonia and CO2 transport, overlapping directly with TGE's cargo handling and fuel gas system portfolios across marine and industrial customers.
• GTT (Gaztransport & Technigaz): GTT designs membrane-type cryogenic containment systems for LNG carriers and is the dominant cargo-containment competitor to TGE's type C tank solutions. Both firms sell engineered gas-handling systems directly to shipyards and shipowners building gas carriers.

Others

• Honeywell UOP: Honeywell UOP licenses gas processing and liquefaction technology used in LNG/CO2/hydrogen infrastructure. It is an adjacent technology supplier whose process know-how overlaps with the cryogenic handling expertise TGE brings to marine fuel-gas systems.
• Air Products: Air Products is a major industrial gas and cryogenic equipment supplier with growing involvement in hydrogen and CO2 infrastructure. It is adjacent rather than directly competitive but increasingly relevant as a partner/competitor in CCS value chains.

Emerging players

• Hexagon Purus: Hexagon Purus supplies composite Type 4 high-pressure vessels for gas storage and transportation, including marine LNG/LPG applications, emerging as a competing lightweight storage solution to TGE's type C tank designs.
