Cleaner, quieter berth operation
Reducing or stopping auxiliary generators cuts onboard fuel burning at berth, lowering local exhaust emissions, vibration and noise. Overall carbon benefit depends on the shore electricity mix.

Engineering & Services
Engineering services for shipowners, shipyards and ports, covering shore power, dry docking and shipyard tooling with project planning, site coordination, acceptance and after-service support.
Shore power at a glance
Power the vessel from shore while at berth — without running auxiliary generators.
Shore power — also known as OPS, AMP or cold ironing — supplies a berthed vessel from the port electrical grid. A complete system can include frequency and voltage conversion, distribution, protection, interlocking, cable management, ship-side receiving equipment and controlled transfer to the vessel switchboard.

System advantages
More than a power connection — a cleaner, safer and more flexible berth-power strategy.
The value of shore power comes from the complete ship–shore system: energy conversion, safe transfer, cable handling, automation, monitoring and lifecycle support all work together.
Lower fuel use and auxiliary-engine hours
Where shore electricity is economically favourable, shore power can reduce berth fuel consumption while also reducing auxiliary-engine running hours and related maintenance demand.
Stable voltage and frequency
Static frequency conversion and transformer options match shore-grid power to the vessel requirement, supporting 50/60 Hz and project-specific LV or HV distribution.
Safer, smoother power transfer
Synchronising checks, interlocks, protection logic and automated transfer sequences can reduce the risk of interruption, incorrect operation and inrush during ship–shore changeover.
Flexible capacity and vessel compatibility
Modular converters, multiple feeders and flexible cable-management layouts can be configured for different vessel classes, berthing positions and high-power hotel or cargo-working loads.
Automated operation and remote visibility
PLC/HMI automation can support guided or one-touch operating sequences, remote status monitoring, alarms, energy data and optional cloud/edge analytics for lifecycle management.
Field engineering
Ship–shore interfaces planned around real berth operations.
Power conversion, cable management, interlocking, protection and operating sequence are coordinated as one system.
Solution configuration
Configure shore-side, ship-side and control layers as one coordinated system.
The final package is defined from port grid conditions, vessel voltage and frequency, load demand, berth layout, cable route, transfer philosophy and class requirements.
01
Shore-side system
Convert, distribute and deliver grid power safely to the vessel connection point.
Frequency conversion and voltage matching
- Grid interfaceIncoming switchgear, metering and protection are configured to the local grid and project capacity.
- 50/60 Hz conversionStatic frequency converters match grid frequency to vessel demand where shore and ship frequencies differ.
- LV/HV adaptationTransformers and distribution equipment can be included for project-specific low- or high-voltage supply.
Connection boxes and cable management around the berth
- Socket / connection boxFixed or mobile connection points are selected around berth layout and vessel interface position.
- Cable managementCable reels, cranes or mobile cable-management systems reduce manual handling and keep the operating area organised.
- Berth flexibilityCable reach and interface location can be engineered for changing vessel mooring positions and different hull arrangements.
Automated sequencing, protection and remote supervision
- PLC / HMIGuided or automated operation sequences display status, alarms, measurements and operating steps.
- Protection & interlockingTypical functions include overcurrent, voltage/frequency, earth-fault, phase-sequence, emergency-stop and ship–shore interlocks as required.
- Remote managementCommunication interfaces can support remote monitoring, energy metering, event records and upper-level management platforms.
02
Ship-side system
Receive shore power, manage the connection and transfer load to the vessel safely.
Shore-power receiving interface to the vessel switchboard
- Shore power boxProvides the onboard receiving point with switching, indication, metering and protection according to the project design.
- Main switchboard interfaceThe shore connection is coordinated with the existing main switchboard, breakers, earthing philosophy and vessel protection system.
- Transformer optionShip-side transformer or isolation equipment can be added where voltage adaptation or galvanic separation is required.
Safe storage, deployment and recovery of the ship–shore cable
- Cable winch / reelShip-mounted cable handling can be configured where the vessel carries the connection cable.
- Plug & socket interfaceConnection hardware is selected according to voltage level, current rating, vessel type and applicable shore-connection standard.
- Mechanical protectionCable routing, strain relief and handling logic are designed to reduce mechanical stress during berth operations.
Controlled transition between onboard generation and shore power
- Synchronising checksVoltage, frequency, phase sequence and phase angle are checked before parallel or transfer operation when required.
- Parallel / transfer logicThe system can be engineered for break-before-make or synchronised closed-transition strategies according to vessel requirements.
- Load coordinationLoad sharing, capacity limits and operating permissions can be coordinated to support stable high-load berth operation.

Shore power equipment
A complete equipment package for both shore-side and ship-side connection.
The system can be configured around berth conditions, cable handling requirements, vessel interfaces and class expectations, with coordinated equipment on both sides of the connection.
Shore-side equipment
