FAQ

What factors determine the tensile strength of subsea mining cables?

The required tensile strength depends on cable length, suspended weight, deployment method, equipment loads and operating conditions. Steel wire armor or dedicated strength members can be incorporated into subsea mining umbilical cables when additional mechanical reinforcement is required. The cable structure should be engineered according to the project's specified working load and safety requirements.

How does water pressure affect deep sea mining cable design?

Hydrostatic pressure increases with water depth and can affect cable materials, structural components and any internal voids or cavities. Deep sea mining cables should be designed for the specified operating depth, with insulation, sheath materials and structural construction selected according to the pressure and environmental requirements. Pressure resistance should be validated for the intended cable design rather than assumed from armor construction alone.

How do you select cables for dynamic subsea mining operations?

Cable selection should consider repeated bending, tensile loads, abrasion, torsion where applicable, minimum bending radius and compatibility with winches or cable reels. Dynamic ROV tethers and moving umbilical cables may require different constructions from cables intended for static subsea installation.

Can steel wire armored ROV cables be used in deep sea mining systems?

Steel wire armored ROV cables can be suitable for applications requiring enhanced mechanical protection and tensile reinforcement, depending on the cable construction and operating loads. Their suitability for a particular deep sea mining system must also account for operating depth, dynamic movement, electrical or optical transmission requirements and the specified mechanical performance.
