Low-Voltage Shore Power Cable Management System | Ship-to-Shore Electric Cable

Product Specification

Low-Voltage Shore Power Cable Management System | Ship-to-Shore Electric Cable Reel

Product Overview

This low-voltage shore power cable management system is a motorised reel-based CMS used to store, deploy, retrieve, guide, and monitor the flexible shore power cable between a vessel and a compatible berth connection. The supplied reference configuration combines an electric cable reel, reduction gearbox, electrical slip ring, PLC-based control, tension monitoring, cable-length monitoring, cable guide arrangement, shore power cable, and connection hardware as one integrated cable-handling package.

The system supports low-voltage shore connection after the vessel is safely berthed. Once the complete ship-to-shore electrical connection, protection, safety-loop, interlocking, and load-transfer sequence has been completed, the vessel can receive electrical power from shore and reduce or stop operation of auxiliary diesel generators during the port stay. This helps reduce local exhaust emissions and noise at berth. IEC/IEEE 80005-3:2025 is the current international standard for low-voltage shore connection (LVSC) systems in the applicable rating range; final compliance must be confirmed for the complete ship/shore system, not from the cable reel alone.

Quick Specifications

Shore Power Cable Management, Connection & Safety Advantages

• Reel-based cable management keeps the shore connection cable stored in a controlled arrangement when not in use and provides managed deployment and recovery during connection and disconnection.

• Automatic tension management can pay out or retrieve cable within defined limits as vessel position or tidal level changes, helping reduce the risk of excessive cable tension, uncontrolled slack, or poor lead into the reel.

• Cable-length and tension monitoring provide operating feedback for deployment status and can be integrated with alarms, permissives, emergency stop, and project-specific safety-loop logic.

• The PLC can coordinate reel direction, motor control, tension feedback, length feedback, local / remote commands, and interface signals. The final cause-and-effect matrix should be confirmed together with the ship and shore electrical design.

• The slip-ring arrangement maintains electrical continuity through the rotating reel. Final current rating, insulation level, temperature rise, creepage / clearance, earthing, and inspection requirements should match the approved electrical design.

• The cable guide / roller arrangement controls the cable lead into and out of the reel. Guide geometry should be checked against the actual cable minimum bending radius, connector handling route, quay / deck arrangement, and expected relative ship movement.

• As part of a complete LV shore connection, the CMS supports safe cable handling so the vessel can transfer hotel and auxiliary electrical load to shore supply. The resulting reduction in local exhaust emissions and noise occurs only after the complete shore connection system is safely connected, energised, and placed in service.

Custom Attributes

• Product Category: Low-voltage shore power Cable Management System (CMS) → reel-based equipment for ship-to-shore cable storage, deployment, retrieval, guidance, and monitoring.

• Reference Electrical Rating: 350 A / AC 690 V → within the application range of IEC/IEEE 80005-3:2025; complete LVSC compliance remains subject to the final system design and approval scope.

• Cable Capacity: Approx. 50 m, OD ≤65 mm → final reel capacity depends on actual cable construction, minimum bending radius, winding arrangement, connector tail, and reserve turns.

• Automatic Tension Management: PLC + tension feedback → controls pay-out / retrieval within defined limits to protect the shore cable during normal vessel movement.

• Monitoring: Cable length + tension + operating status → supports deployment indication, alarms, permissives, and project-specific interlock logic.

• Connector Interface: Project-specific → plug, socket / ship connector, protective-earth, pilot / control contacts, and IEC 60309-5 compatibility should be confirmed where applicable.

• Environmental Benefit: Enables managed ship-to-shore cable connection → supports transfer of vessel electrical load to shore power so auxiliary generators can be reduced or stopped during berth, helping lower local exhaust emissions and noise.

• Cyber Resilience: To be confirmed by project scope → PLC / HMI networking, remote access, software documentation, and class cyber requirements must be defined before any compliance statement is made.

How It Works

Vessel berths and the LV shore connection is prepared → Cable is deployed from the reel under controlled tension → Plug / connector interface is safely connected → Protection, safety-loop and interlock conditions are verified by the complete LVSC system → Shore supply is energised and vessel load is transferred according to the approved operating sequence → Auxiliary generators may be unloaded or stopped during the port stay → CMS monitors cable tension and deployed length while connected → Before departure, load returns to onboard generation, shore power is isolated, the cable is disconnected and retrieved onto the reel

Applications

At-berth low-voltage shore connection | Shipboard shore-power cable management | Shore-side reel-based CMS | Port electrification / cold-ironing projects | Newbuilding shore-power integration | Retrofit shore connection projects | Compatible ferries, workboats, tankers and other commercial vessels subject to project electrical rating

Certifications & Advantages
