Company Overview and History

Our company was founded in 1984 as the Japanese branch of a French ocean survey company and has since been primarily involved in importing and selling large ROVs developed overseas, as well as providing maintenance services. After becoming a branch of the Singapore head office, we became a fully independent Japanese corporation in 1994 and have continued to operate as such.

We offer a wide range of equipment, from small and large ROVs to various instruments used for marine surveys and underwater operations, and aim to provide comprehensive support for our customers, from initial introduction to post-purchase technical support, repair and replacement parts.

We have a rigorous selection process for our equipment and only offer products that have received high evaluations and have been proven effective through extensive field experience overseas. If you are considering the introduction of marine or underwater equipment, please feel free to consult with us.

Our company’s Windows software, which we design, produce and sell, provides real-time visual representation of data from GPS, underwater positioning devices and other survey and observation equipment. Our software has been widely adopted by customers conducting marine surveys or offshore/underwater operations to efficiently and safely manage their position in these environments.
