What Sunbo Unitech does
SB Sunbo (formerly SB Sunbo / 선보) is a Korean privately-held industrial group, founded in 1986/1987 and headquartered in Busan, that designs and manufactures marine and energy equipment for the global shipbuilding and LNG industries. Its core products include FSRU (Floating Storage Regasification Unit) systems, fuel gas supply systems (FGSS), LNG liquefaction modules, regasification units, cryogenic cold boxes (including Korea's first aluminum cold box), NG heaters, high-capacity marine pumps, and — more recently — water electrolysis systems for green hydrogen production. The company is recognized for introducing the world's first 'unit technology' approach to shipyard equipment processing, and it operates across three Busan-area manufacturing facilities (Dadae-dong and Gupyeong-dong) plus a Gwangyang plant supporting LNG and gas handling production.
The company is organized into four business divisions — Marine Solutions, Gas Solutions, Eco & Decarbonization, and Open Innovation — and serves as a Tier-1 supplier to the three largest Korean shipbuilders (Hyundai Heavy Industries, Samsung Heavy Industries, Hyundai Samho Heavy Industries) as well as HJ Heavy Industries and LOTTE in the LNG/energy segment. Revenue is generated primarily through project-based, one-time equipment supply contracts to shipyards, with the export performance recognized via the Busan $50M Export Tower award. The go-to-market is direct enterprise field sales, complemented by participation in KORMARINE and other industry events and active IR/disclosure communications.
In January 2026, SB Sunbo consolidated its operating subsidiaries (Sunbo Engineering, Sunbo Unitech, Sunbo Hi-tech, Sunbo Peace) and angel-investment arm (SB Angel Partners) into a single integrated corporation, led by Chairman Choi Geum-sik, signaling a deliberate scale-up. Recent strategic moves — including MOUs with Turkey's Karadeniz Holding, a Pennsylvania state-level U.S. expansion visit, and a joint Korean shipyard-equipment delivery platform — point to a growth posture anchored on Korean shipyard dominance, a pivot into hydrogen and carbon-capture, and selective geographic diversification.

Sunbo Unitech competitors and assessment
Company assessmentDirect peers
- Wärtsilä: Wärtsilä is a leading global marine systems integrator that supplies LNG fuel gas supply systems, cargo handling, and regasification equipment for LNG carriers and FSRUs — directly comparable to SB Sunbo's marine and gas divisions and serving the same shipyard customers.
- MAN Energy Solutions: MAN Energy Solutions manufactures marine engines and dual-fuel propulsion systems, including LNG fuel supply packages for ocean-going vessels — directly comparable to SB Sunbo's FGSS and marine propulsion-adjacent offerings, with similar end customers among global shipyards.
- Hanla IMS: Hanla IMS is a Korean marine equipment manufacturer supplying pumps, valves, and FGSS components to domestic and global shipyards — directly comparable to SB Sunbo in terms of product scope (HP pumps, FGSS) and Korean shipbuilder customer base.
- TGE Marine Gas Engineering: TGE Marine is a specialist in LNG cargo handling and fuel gas supply systems for LNG carriers and FSRUs, closely matching SB Sunbo's regasification unit, liquefaction module, and gas handling product line in scope and customer type.
- Cryostar (part of Chart Industries): Cryostar designs cryogenic pumps, vaporizers, and LNG regasification equipment — directly overlapping with SB Sunbo's cryogenic pumps, NG heater, and regasification unit portfolio for marine and onshore LNG applications.
- Mitsui E&S (Mitsui Engineering & Shipbuilding): Mitsui E&S manufactures marine propulsion and LNG-related equipment including fuel gas supply systems for LNG-fueled vessels, making it a closely comparable Japanese peer to SB Sunbo's marine and gas solutions.
Others
- Hyundai Heavy Industries: Hyundai HI is both a major SB Sunbo customer and a vertically integrated shipbuilder pursuing proprietary LNG carrier and FSRU solutions; included as a peer because its in-house engineering capability is the most direct competitive threat to SB Sunbo's marine equipment business.
- Samsung Heavy Industries: Samsung HI is a key SB Sunbo customer for LNG carrier components and is also expanding its own marine engineering capabilities, making it both a buyer and a long-term potential competitor for marine LNG equipment supply.
Broad incumbents
- Kawasaki Heavy Industries: Kawasaki Heavy Industries is a large diversified industrial conglomerate that builds LNG carriers and supplies cryogenic gas handling systems, comparable to SB Sunbo's marine equipment and LNG handling divisions, but operating across a much broader portfolio including aerospace, motorcycles, and rolling stock.
- Höegh Evi (formerly Höegh LNG): Höegh Evi operates FSRUs and is a major buyer/operator of regasification technology, comparable to SB Sunbo's FSRU-adjacent gas handling equipment business from the demand side and providing insight into how FSRU customers evaluate equipment vendors.
