Umbilical Cable-ROV Cable

Umbilical Cable

Umbilical cable, named after the umbilical cord of mammals, are so named because they provide a «lifeline» like support for underwater production systems in an underwater environment. Umbilical cables integrate power, signaling, data and control functions into one, providing the necessary energy and communication support for underwater equipment, and are an important and indispensable part of modern offshore engineering.

Umbilical Cable structure and technical parameters

ROV Cable

The ROV Cable, or Remotely Operated Vehicle Cable, is an important component that connects the Remotely Operated Vehicle (ROV) to the control vessel or other equipment. It is responsible for transmitting power, signals and data to ensure that the ROV can work stably and efficiently in an underwater environment.ROV cables usually have a complex structure, including multiple units such as power cables, signal cables, video cables and control cables, etc., in order to meet the needs of ROVs in different application scenarios.

ROV Cable structure and technical parameters

Conductor:
Material: mostly stranded with high purity oxygen-free copper or tinned copper wires to improve electrical conductivity and tensile strength.
Structure: multi-stranded stranded design to increase the flexibility and anti-fatigue properties of the cable.
Insulation:
Material: high-performance insulating materials resistant to seawater, corrosion and abrasion, such as fluoroplastic, PE/TPEE/TPU/ETFE.
Thickness: Determined according to the voltage level and application requirements to ensure electrical safety.
Shielding layer:
Type: Mostly tinned copper wire braided mesh or aluminum foil mylar tape, etc. for electromagnetic shielding to reduce signal interference.
Coverage: High coverage design to improve the shielding effect.
Reinforcement element:
Material: optional tensile steel wire rope, Kevlar fiber and other high-strength materials to enhance the cable’s tensile performance.
Structure: Designed according to the diameter and tensile demand of the cable to ensure that the cable is not easy to break when subjected to external forces.
Outer sheath:
Material: special materials that are seawater resistant, abrasion resistant and UV resistant are used, such as polyurethane (PUR) and TPU.
Color: Usually yellow, orange and other eye-catching colors for easy underwater identification and recovery.
Electrical performance:
Rated voltage: determined according to application requirements, such as 450/750V, 500V, 1000V, etc.
Insulation resistance: At a specific temperature (e.g. 20℃), the insulation resistance value needs to meet certain requirements, such as ≥20MΩ/km.
Withstanding voltage: no breakdown under AC or DC test voltage to ensure electrical safety.
Physical properties:
Outer diameter: determined according to the number of cores of the cable, thickness of insulation layer and reinforcing elements.
Bending radius: For mobile installation, the bending radius is usually 8 to 10 times the cable’s outer diameter; for fixed installation, the bending radius can be reduced to 5 times the cable’s outer diameter or less.
Operating temperature: Wide range, e.g. -40°C to +90°C or higher, depending on cable material and design.

Umbilical Cable-ROV Cable Application

High abrasion resistance: Umbilical Cable-ROV Cable need to have good abrasion resistance to withstand friction and abrasion in the complex underwater environment.

High pressure resistance: As ROVs usually work underwater, the cables need to withstand the effects of the underwater high-pressure environment, so they have high pressure resistance.

Strong corrosion resistance: the marine environment is highly corrosive to cables, Umbilical Cable-ROV Cable need to have good corrosion resistance to ensure long-term stable operation in the marine environment.

High flexibility: ROVs need to move and bend at high frequencies during underwater operations, so Umbilical Cable-ROV Cable need to be highly flexible to adapt to the movement needs of ROVs.

Customized design: Umbilical Cable-ROV Cable often need to be customized to the specific ROV model, application and operating environment. This includes customization of the cable’s length, number of cores, cross-sectional area, insulation material, tensile reinforcements, and other parameters. Customized design allows ROV cables to better meet the needs of a variety of complex applications.

Anti-electromagnetic interference: ROV cables need to have good anti-electromagnetic interference capability when transmitting signals and data to ensure signal stability and accuracy.

Zero or low buoyancy design: Umbilical Cable-ROV Cable are designed with zero or low buoyancy to minimize the interference of cable buoyancy on ROV operation and to improve the maneuverability and stability of the ROV. This design is typically achieved by wrapping the internal conductors of the cable with a high-density material or by adjusting the density of the cable.
