Subsea umbilicals are deployed on the seabed (ocean floor) to supply necessary control, energy (electric, hydraulic) and chemicals to subsea oil and gas wells, subsea manifolds and any subsea system requiring remote control, such as a remotely operated vehicle. Subsea intervention umbilicals are also used for offshore drilling or workover activities.
Application:

Derul Cable is able to design and manufacture Remotely Operated Vehicle (ROV) tethers. Power & signals are integrated into a cable structure, so ROV tethers can be used to transmit both electricity and signal. ROV tethers normally resort to coaxial and twisted pairs to achieve signal transmission. The cable which connects the underwater vehicle with the controller significantly affects its performance, so it must ensure stable signal transmission. The neutrally buoyancy helps vehicle run smooth with less water resistance and loading.
