Towed Systems

Einhorn Engineering has a long history of designing and building towed systems. Whether towing a single towbody or an array of towbodies, our team can transform your requirements into a system specifically designed for the application. Our extensive experience with all aspects of the towed system has resulted in proven equipment that exhibits solid and stable towing performance for the sea states and depths you need to work at.

Utilizing State of the Art Tools for State of the Art Performance

Low towbody drag equates to low tow cable tensions which translates into lighter handling system equipment. This saves costs everywhere from the deployment system procurement to mobilization. Our engineers are skilled in advanced solid modeling techniques and have first-hand knowledge of state-of-the-art manufacturing tools. This combination allows us to leverage technologies such as 5-axis machining and 3D printing in the production of towbodies with highly faired, low-drag form factors.
