Towfish Open Frame 

Okeanus by 

SOSI has engineered and built many different open- frame towed body (towfish) systems. While the majority of SOSI tow bodies are towed through the water column, many of our systems are designed for landing on and towing across the seafloor. These sled designs, typically used for cable burial, ocean mining, environmental impact assessment and video/ photographic survey, are not only stable when towed through the water column, but maintain their orientation when landed on the seafloor. Our experienced engineers often integrate instrumentation such as, altitude sensors, environmental sensors, camera / video systems, lighting equipment, telemetry systems, pumps, motor starters and control systems into our tow bodies.
