Overview

A New Generation of Offshore Inspection

SeaCAT is an unmanned surface vehicle (USV) designed for offshore inspection and survey missions, in remotely operated or autonomous mode.

Its aluminum catamaran design provides:

  • Excellent stability

  • Ability to operate in harsh conditions

  • High equipment integration capacity

It offers a modern alternative to conventional vessels for offshore operations.

Multi-drone system
