ROV & Diving Equipment Umbilical Cable

One cable instead of three

A working ROV tether carries power to the vehicle, control commands down to it and video back up. Running these as separate cables adds drag, weight and failure points. Suoqi builds the composite umbilical with all three in one body, screened from each other, around a load-bearing aramid element sized to the tether's working and breaking load.

Mechanics matter more than the conductor

Umbilical failures are mechanical: the cable is dragged over a stern roller, bent through a sheave, and cycled by current and vehicle movement for the length of a survey. The construction therefore uses a short-lay, torsion-balanced core bundle, an anti-friction layer, and a sheath with high tear resistance. Tell us the working depth, the tether length, the vehicle thrust and the sheave diameter and we will engineer around those limits.

Applications

This construction is supplied into the following installations. Tell us which one applies and we will confirm the governing requirement.

Customisation

Core count and cross-section, screen arrangement, sheath compound and colour, print legend, length and termination are all built to order. Send the requirement — including the failed OEM part if this is a replacement — and we will propose the construction and confirm the lead time.
