Figure 1 Shipboard Cable

Thus, any cable that is designated for use aboard ships and vessels is deemed as shipboard cable. They find multiple applications in a wide range of marine and offshore equipment.

These can include cruise ships, submarines, naval and military vessels, and ocean drilling rigs.

2. What Are the Applications of Shipboard Cable?

Shipboard cables are designed primarily for use in ships and vessels. They are used in the marine environment for power supply and delivery.

As marine equipment needs to withstand great degrees of temperature extremities and various hazardous contaminants, shipboard cables are thus specially used to withstand harsh conditions in the marine environment.

Shipboard cables are used in marine and offshore equipment for fixed installations in ships, serving the purpose of power transmission and supply. Shipboard cables are also used in offshore platforms for instrumentation purposes.

Other ranges of applications for shipboard cables include military vessels, civilian ships, submarines, ocean drilling, telecommunication, and internet ranges.

Thus, shipboard cables cover almost every range of functions, including communication, control system, instrumentation, and power delivery.

3. What Is Shipboard Cable for Telecommunication?

Shipboard cables are used for marine appliances in a range of applications, including telecommunication.

Since the first undersea cable was laid at the beginning of the 1850s, these cables have been vastly used for transporting data signals across vast stretches of sea, serving an efficient function as telecommunication links between pieces of land separated by large ocean bodies.

These shipboard cables are designed for use onboard and also in offshore equipment for communication and transfer of information in civilian and naval ships and in vessels.

Control circuits on ship boards make use of the telecommunication cables. Apart from that, they are also suited for use in metallurgical industry works, power plants, and mines.

4. What Are the Characteristics of Shipboard Cable?

Shipboard cables are specifically designed and manufactured to function under adverse conditions, in rugged and rocky terrains, under the seabed, and to endure extreme conditions.

In order to overcome these extremities, shipboard cables generally have the following characteristics:

  • Good inner conductor
    A central band of an excellent conductor like copper or aluminum is necessary in order to ensure an efficient supply of power.
  • Insulation
    To provide the conducting material, a coating, a layer of insulating material like rubber, is added to minimize the risk of damage and loss of signals.
  • Armoring
    Armoring is done to prevent the cable from mechanical stress and heavy load. Heavily galvanized steel wires or non-magnetic materials for single-core cables are used for providing armor.
  • Sheathing
    The sheathing is done to reduce electrical noise from the environment and to ensure the quality of the signal remains intact.
  • Additional protective covering
    According to the needs of the external conditions, outer coverings are installed, usually of PVC, rubber, or polyurethane sheath, and layers of polypropylene yarns and jute can also be added.
  • Corrosion resistance
    In marine environments, constant humid conditions can harm the cable. To prevent that, tinned copper is used, which greatly reduces corrosion.
  • Flexibility
    Shipboard cables have great flexibility and a small bend radius, which makes them easier to handle, and also significantly reduces the installation time.
  • Flame retardant
    To ensure the safety of the vessel, equipment, and staff, shipboard cables are made flame-retardant and fire-resistant.

Prior to their manufacturing, shipboard cables are made to undergo these tests and then passed into the market to ensure the best quality of the manufactured product.
