Launch of Marine Geophysical Surveys Using the "SeaCAT" Unmanned Surface Vessel (USV)

Building on our extensive track record and technical expertise in offshore wind energy—spanning bottom-fixed, floating, and submarine cable projects—we have introduced the "SeaCAT" Unmanned Surface Vessel (USV) as our new marine geophysical survey platform.

Compared to conventional survey methods, SeaCAT offers distinct advantages, including shorter survey timelines, higher productivity, lower fuel consumption and reduced CO2 emissions, elimination of daily port calls, and enhanced safety. By advancing unmanned data collection and remote operations, SeaCAT accelerates operational digitalization and efficiency—driving Digital Transformation (DX) and enabling us to execute projects faster and more effectively.
