Underwater Survey Contract

As a manufacturer of artificial reefs, our company has conducted underwater surveys for nearly thirty years, beginning with the introduction of a remotely operated vehicle (ROV) in 1997. With extensive experience and proven technical capabilities, we meet a wide range of on-site needs across Japan.

Our Underwater Survey Services

• Track record of more than 1,000 survey sites
• Capable of surveying diverse marine environments across Japan
  (from shallow waters less than 5 meters deep to deep-sea areas reaching 300 meters, including offshore locations with challenging sea conditions)
• Capable of inspecting deep-sea targets and capturing tracking footage of swimming fish
• Experienced operators ensure safe and reliable operations

The value of using ROV

Underwater operations are an essential component of social infrastructure in Japan, a maritime nation. However, conventional diving work continues to face safety challenges caused by high water pressure, low temperatures, and poor visibility. By prioritizing safety, we offer ROV-based underwater survey solutions that help address these issues.
