Mitsui E&S Engineering Co., Ltd. ("the Company") was established on April 1, 2018 as a wholly owned subsidiary of Mitsui E&S Holdings Co., Ltd. (formerly Mitsui Engineering & Shipbuilding Co., Ltd.). The Company has been pursuing engineering operations in a range of fields within the scope of EPC (engineering, procurement and construction) in Japan and overseas for the past 80 years, since the days of the former Mitsui Engineering & Shipbuilding Co., Ltd.
Social needs in the future will be increasingly diverse and complex globally, given an increase in energy consumption, the diversification of energy sources, the practical use of non-conventional energy, growing demands for infrastructure and industrial facilities, and expanding demand for the environmental protection.
Under such circumstance, the Company will meet the expectations of its customers in the three areas of business which the Company is now operating (the environmental energy business centered on renewal energy such as biomass, wind power and solar power, the infrastructure business centered on the civil engineering of overseas power generation facilities, and the plant business centered on petrochemical and inorganic chemical plants) and new businesses by utilizing the technologies and expertise which the Company has been cultivating for many years together with its comprehensive engineering strengths, including that of its subsidiaries in Japan and overseas. Based on the corporate philosophy of Mitsui E&S Holdings Co., Ltd. "To continue being a company trusted by society and individuals through our products and services," the Company will vigorously push forward with its goal of creating value in society to address social issues and needs as a reliable engineering company.
