ROV & Underwater Robotics

An ROV tether is a mechanical component as much as an electrical one. It carries power down and video up, is dragged over rollers and through sheaves, and is loaded by current and vehicle movement. Suoqi builds ROV tethers with torsion-balanced core bundles, aramid load-bearing elements sized to the working and breaking load, and neutral buoyancy where the vehicle's thrust budget matters more than the cable's convenience.

What usually governs cable life here

The requirement that decides how long the cable lasts in this installation — and therefore what we change in the construction.

• Neutral buoyancy to avoid loading the vehicle or drifting in current
• Aramid tensile elements rated to working and breaking load
• Screened video and control pairs screened against thruster noise
• Short-lay, torsion-balanced cores for repeated sheave bending
