Tethers supply the vital link from the ROV to the surface or control module. Either directly or via the tether management system through the main lift umbilical. The total services provided by the tether are power, CCTV, signal, & communications via optical, coaxial, or twisted pair conductors.
Mechanical strength is normally incorporated into the design using aramid fibres by multi layer braids or centre strength cords of aramid fibres.
ROV tethers are a strategic component in the supporting performance of the cubicle, so the design & construction has to address, crucial factors such as small diameter, flexibility, ruggedness, buoyancy, depth & handling requirements.
The design criteria is important and familiar to Hydro Group design engineers. Hydro Group have extensive experience and can offer proof and qualification flex testing, pull testing and pressure testing of tether cables, and professional end terminations with various connector types.
All Hydro Group products are designed in-house by our team of experienced development Engineers. The team includes Electrical, Mechanical, Optical Engineers and Production Engineers. Hydro Group can design a completely new cable / connector solution or adapt an existing proven product to suit your application.
