TFOU, TFCU by Suzhou Draka Cable Co. Ltd.. DNV TA certificate TAE000019V.
Inspector Detail
▸
Common issues
- Outer sheath cracking or UV degradation on exposed deck runs
- Chafing at cable transits, hangers, and cable tray edges
- Insulation resistance degradation from moisture ingress at glands/terminations
- Overheating or discoloration at overloaded circuits or poor terminations
- Mechanical or rodent damage in accommodation/engine room runs
Inspection checklist
- Visual inspection of exposed cable runs for sheath damage, chafing, UV cracking
- Check cable gland and transit sealing for water tightness
- Insulation resistance (megger) test on selected circuits per the PMS
- Check cable support/tray fixings are secure and not chafing the sheath
- Verify cable marking/identification is legible
- Check termination lugs/glands for corrosion or overheating signs
Service intervals
| Insulation resistance testing | per class/PMS schedule, commonly annual for critical circuits |
| Visual inspection of exposed runs | at each engine room/deck round or per PMS |
| Gland/transit reseal | on condition, typically at dry-docking if degraded |
Typical wear limits
| Insulation resistance | compare against the vessel's own baseline/PMS trend - the absolute minimum acceptable value depends on cable voltage class and applicable class rules, not a single generic figure |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Critical spares
- Cable gland/transit seal sets
- Termination lugs matching cable size
- Spare cable length for critical/high-risk runs, kept on condition rather than routinely stocked
Safety
- Damaged insulation on power cables presents electric shock and fire risk
- Cables routed near hot machinery surfaces need intact thermal protection/sheathing
- Confirm isolation and zero-energy state before working on any cable
Class survey
DNV Type Approved cable (certificate TAE000019V) - class checks that the type approval documentation matches the installed cable, reviews insulation resistance test records, and assesses general condition at periodic surveys; no scheduled replacement interval is set by class absent physical degradation.
