Similar in operation to ROV Main Cables, these umbilical cable types provide electrical power, electrical and/or optical signal and occasionally hydraulic or pneumatic services for a number of operations, such as trenching, sampling, ploughing or surveying.
Most often armoured for both mechanical protection and tensile strength, cables of this type resist the damaging external effects from the seabed conditions, the gruelling dynamics of handling forces, vessel motion and tidal forces, while supporting the weight of the associated package. Where weight is a consideration, however, synthetic fibre reinforcements may also be considered.
Our designs offer the most compact electrical and fibre optic assembly diameter to minimize overall cable OD and therefore handling gear and deck space.
These variants can be produced in long continuous lengths.
Features and Benefits:
Fiber Reinforced
-
Combination options of high power, signal, and optic layout / sizing
-
Choice of component configurations including singles, pairs, and quads
-
Choice of optical fibers with various MM SM options
-
Special thin wall insulation and high temperature capability to 125 degrees centigrade
-
Smaller diameter cables, smaller winches, less deck space
-
Choice of high modulus fiber strength layers offer significant weight savings compared with wire armored variants
-
Vectran fiber rather than aramid offers high strength, less self abrasion, and longer service life
-
Optimized diameter cables for deepwater long lengths (storage and operation from optimized rig/platform or vessel foot prints)
-
Qualification testing for added confidence from pre-use verification
-
Mechanical and electrical termination
