Offshore Platform Mud-resistant Cable

A sheath compound selected for drilling mud, mineral oil and hydrocarbon exposure, so the cable survives the deck environment rather than the datasheet.

Product overview

Construction and performance

A platform deck is not a ship interior. Cables are exposed to drilling mud, base oil, hydraulic fluid and wash-down, and the sheath has to survive that exposure for years rather than months. NEK 606 defines the mud-resistance test: sheath samples are immersed in base oil and in drilling-fluid blends, and the change in mass, tensile strength and elongation must stay within limits. A sheath that passes IEC 60092-359 alone is not necessarily mud resistant, which is why the specification has to name NEK 606 explicitly.

Construction

  • Tinned copper conductor, class 2 or 5
  • EPR insulation
  • Bedding and armour where specified (galvanised steel wire or bronze wire)
  • High oil-resistance SHF2 or CPE sheath
  • Mud resistance verified to NEK 606
  • LSZH variants to IEC 60754 / IEC 61034 on request

Applications

  • Offshore drilling platforms
  • Production and processing decks
  • Drawworks and mud-pump circuits
  • FPSO and floating production units

Selection notes

What to confirm before ordering

What does NEK 606 actually test?
NEK 606 defines mud-resistance testing for offshore cable sheaths, including exposure to base oil and to drilling-fluid blends, with limits on swelling and on tensile and elongation change. A sheath that passes IEC 60092-359 alone is not necessarily mud resistant.
Is armouring required on a platform deck?
Not always, but it is common on cable routes exposed to mechanical damage, and it is mandatory where the cable is buried or run in a hazardous area without conduit. Steel wire armour also provides the earth-continuity conductor required in many offshore installations.
How is the cable marked for traceability?
Each drum carries the cable type, construction, length, drum number and project reference. Batch test reports and sheath compound certificates are issued with the delivery documents.

Standards & type approval

IEC 60092-359, NEK 606 (mud resistance), IEC 60092-353 construction, IEC 60332-3, IEC 60754 and IEC 61034 for LSZH variants.
