Since its establishment in 2004, Marsen Co., Ltd. has been leading the growth of the ship equipment industry through continuous development and innovation of technologies for ship measurement equipment.
The driving force for the company's growth is the continuous development of technologies. The company exerts full-scale efforts to develop new technologies such as explosion-proof devices and measurement sensors as it is necessary to nurture the ship equipment sector as a high value-added industry. In addition, the company is seeking to localize the level, pressure, temperature, and gas measurement devices which other companies mostly depend on imports.
The company operates the business in a virtuous cycle in which the profits from managing the company are redistributed to employees and invested in the development of new technologies, making efforts to practice transparent management.
Marsen has been working on pioneering emerging overseas markets by signing branch and agency contracts in China, Indonesia, and Europe.
The company is also seeking to advance into marine plants and other industries. We promise to become a leading company in the ship and marine plant industries in the near future.
