Shore Power Connection System · Shore Connection

Class-certified type (DNV register) · technical data sheet not yet verified

Cavotec shore connection. Cavotec has installed more shore power systems worldwide than any other supplier, with over 150 installations across six continents. The company has more than 40 years of experience in the design, manufacture and installation of shore power and cold ironing systems, also known as Alternative Maritime Power (AMP) or utility connections in port.

Inspection

Inspector Detail

Common issues

  • Shore connector contact overheating from poor mating force or contamination at the ship-shore interface
  • Voltage/frequency mismatch faults between shore supply and ship distribution during changeover
  • Cable reel/handling mechanism jams or misalignment during connection
  • Insulation resistance degradation on the flexible high-voltage shore cable from repeated flexing and weather exposure
  • Interlock or earth continuity fault preventing energisation
  • Control/communication link failure between ship and shore synchronising panel
  • Connector seal ingress of water or salt causing tracking or flashover at low insulation resistance

Inspection checklist

  • Visual check of shore connector pins/sockets for pitting, discolouration, or arcing marks
  • Insulation resistance test on shore cable and ship-side receiving cable at rated voltage
  • Verify earth continuity and interlock sequence before energisation
  • Check cable reel/handling mechanism for smooth operation and jacket condition
  • Confirm voltage, frequency and phase sequence match between shore and ship before closing the breaker
  • Inspect connector gaskets/seals for weather-tightness
  • Torque check on busbar and terminal connections in the shore connection cubicle
  • Functional test of synchronising/changeover logic and protection trip settings

Service intervals

Connector contact inspectionevery connection cycle or minimum annually
Insulation resistance test (shore cable + ship receptacle)annually
Interlock and protection relay function testannually
Cable reel/handling gear lubrication and mechanical checkevery 6 months
Torque check on power connectionsannually or after any connector replacement

Typical wear limits

Insulation resistance, shore cablecommonly expected well above 100 M-ohm for cables of this class - compare to the commissioning baseline and manufacturer minimum rather than a single fixed figure
Connector contact resistanceshould stay within the manufacturer's stated range - a rising trend indicates contact wear or contamination

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

Critical spares

  • Shore connector plug/socket contact set
  • Interlock/earth continuity monitoring relay
  • Flexible high-voltage shore power cable section
  • Connector sealing gaskets
  • Control/communication interface module for the ship-shore synchronising panel

Safety

  • High voltage (6.6 kV class) present at the ship-shore interface - strict lockout/permit-to-work before connector handling
  • Risk of energising with reversed phase sequence or frequency mismatch if the interlock chain is bypassed
  • Electric shock hazard from damaged cable insulation or connector seals
  • Arc flash risk during connection/disconnection if not de-energised per procedure

Class survey

Classification societies assess high-voltage shore connection (cold ironing) systems against IEC/ISO 80005 requirements. Surveyors look for interlock and earthing verification records, insulation resistance test history, and protection relay setting documentation. Where the vessel carries a shore-power notation, this typically falls under periodic (commonly annual) electrical survey rather than continuous survey machinery.

Estimated lifetime: Connector and cable assemblies on high-voltage shore power systems are generally rated in connection cycles rather than running hours; the shore-side cubicle and switchgear typically have a design life in the order of 20-25 years with periodic component replacement - confirm against Cavotec's own system documentation

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
