Inspection

Inspector Detail

Common issues

  • Insulation resistance degradation from moisture ingress at terminations or a damaged outer sheath
  • Mechanical damage to the outer sheath from chafing against structure or poor cable route support
  • Overheating/insulation aging at terminations from loose connections or undersized termination kits
  • Developing partial discharge activity in aged or damaged insulation at this voltage class
  • Sheath cracking from repeated flexing at cable transits or, on exposed runs, UV exposure
  • Water treeing in the insulation over long service life, particularly in damp environments

Inspection checklist

  • Visual inspection of accessible cable runs for sheath damage, chafing, or degraded supports
  • Insulation resistance (megger) test at scheduled intervals and after any suspected damage
  • Thermal (infrared) scan of terminations and switchgear connections under load
  • Inspect cable transits/glands for sealing integrity (watertight/gastight as required)
  • Check termination and joint condition for signs of overheating or tracking
  • Verify cable support and clamping is intact with no excessive sagging or chafe points
  • Confirm fire-stopping at bulkhead/deck penetrations is intact

Service intervals

Insulation resistance testannually, or per class/maker recommendation for 6/10kV circuits
Thermal imaging of terminations under loadannually
Visual inspection of accessible runs and transitsat each internal survey
High-voltage proof/partial discharge testat the class special survey interval for this voltage class - confirm against the applicable class rules

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Typical wear limits

Insulation resistancea commonly referenced general guide is roughly 1 M-ohm per kV of rated voltage as a minimum - the vessel's electrical engineer should confirm the actual acceptance value for this 6/10kV cable, as this is not a substitute for the cable/class-specific criterion

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Termination/jointing kit rated for 6/10kV, matching cable size and insulation type
  • Cable glands matching the cross-section and armor type
  • Spare cable length for emergency repair (maker/yard-specified minimum run)
  • Heat-shrink or cold-shrink termination repair accessories

Safety

  • 6/10kV is high voltage for marine systems - strict lock-out/tag-out and voltage-absence verification is required before any work
  • Residual charge in HV cables after de-energization - discharge and earth before handling
  • Damaged insulation on an energized HV cable presents a flashover/arc-flash risk
  • Fire risk from overheated terminations - never exceed the cable's current rating or ignore a recurring thermal hot spot

Class survey

Class surveys of high-voltage cable systems typically require insulation resistance test records, confirmation of cable route fire integrity at transits/penetrations, and periodic HV testing per the applicable class rules for 6/10kV distribution.

Estimated lifetime: Not applicable in running hours - marine 6/10kV power cable of this type is typically designed for a service life of 20-25+ years, condition permitting, and is assessed by insulation testing rather than hour-based renewal

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
