Dongbang Ship Machinery Co., Ltd. is a South Korea-based manufacturing company primarily engaged in the fabrication, surface treatment, and supply of industrial piping systems and marine environmental equipment for the shipbuilding, offshore, and onshore plant engineering sectors. Founded in 1994 and headquartered in Changwon, South Korea, the company operates as a consolidated subsidiary of Sejin Heavy Industries Co., Ltd. and is listed on the KOSDAQ under the ticker symbol 099410. Dongbang Ship Machinery conducts its operations through two core business divisions: the Piping System (PS) Division and the Water & Environment (WE) Division. The company's comprehensive product and service portfolio includes carbon steel, stainless steel, and specialty alloy pipe spools engineered for commercial vessels, floating offshore structures, and industrial plants; high-precision piping modules and cryogenic piping systems designed for liquefied natural gas (LNG) and liquefied petroleum gas (LPG) carriers; automated blasting, painting, anti-corrosion coating, and specialized surface finishing services; marine Sewage Treatment Plants (STP) developed for onboard wastewater processing in compliance with International Maritime Organization (IMO) effluent standards; and evaporative fresh water generators, including the ISF-C Series, which utilize marine engine waste heat for seawater desalination. In recent strategic developments, Dongbang Ship Machinery broadened its operational scope and environmental technology portfolio by acquiring the Sewage Treatment Plant (STP) business division from affiliate IL SEUNG Co., Ltd. in June 2024, thereby establishing its dedicated Water & Environment Business Unit. Amid increased global demand for high-value and eco-friendly vessels, the company has expanded production capacity to support surging LNG carrier construction cycles, capitalized on integrated manufacturing synergies within the Sejin Heavy Industries group, and refreshed its executive management structure in early 2026 to accelerate operational efficiency and international market expansion.
