Open Frame Tow Bodies

ARGO

SOSI has engineered and built many different Open-framed 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. Additionally, SOSI has designed self-propelled towfish for deep-water operation such as the ARGO which was used to discover the resting place of the Titanic.

Our open-framed tow bodies are highly stable, hydrodynamically clean, high-speed systems based on extensive numerical analysis and full scale model testing. They are typically “heavy” constructed of aluminum or steel, but can also be provided with syntactic foam flotation for neutral or slightly positive buoyancy. Often they are designed to carry video, photographic cameras and their associated flood and strobe lights. Other options include the incorporation of scanning sonar, side-scan sonar and sub-bottom sonar equipment. The simple open frame design allows flexible placement of these options and easy access to electronics housings, cameras, cable terminations, and other critical items protected by the tested design and structural integrity of our open-framed towfish.
