Sector Overview

Power Infrastructure for Cleaner and More Flexible Port Operations

MJR supports port electrification through shore-to-ship power, power conversion, energy storage, microgrids, automation and associated electrical engineering. Its QuayPower™ platform is designed as a modular containerised solution that can be integrated into existing quaysides, ports and harbours, with configurations ranging from large grid-connected systems to smaller applications where available grid capacity is constrained.

Who MJR supports Port operators, harbour authorities, local authorities, ferry operators, terminal operators, shipyards and project teams planning shore power, vessel charging or wider port electrical infrastructure.

Sector Challenges

Integrating Shore Power into Existing Port Infrastructure

Port shore power is not simply a connection point at the berth. Grid capacity, vessel voltage and frequency, connection method, berth layout, future demand and operational control all influence how the system needs to be engineered.

Grid Capacity & Peak Demand

Available grid capacity may not match the short-duration, high-power demand of vessel charging or shore-to-ship power, particularly at remote ports, island communities or constrained sites.

Different Vessel Power Requirements

Ports may serve vessels with different electrical voltages, frequencies and power demands, requiring appropriate power conversion and controlled integration between shore and vessel networks.

Existing Berth Constraints

Many projects need to be retrofitted around existing quaysides, utilities and operational areas without creating unnecessary new infrastructure or restricting normal port activities.

Connection & Power Transfer

Manual, semi-automated or automated connection arrangements need to transfer vessel load between onboard generation and shore power in a controlled way while maintaining suitable electrical coordination.

Monitoring, Metering & Billing

Operators need visibility of power usage, system condition and charging activity, particularly where infrastructure is shared across vessels, berths or customers. MJR's current QuayPower proposition includes remote visualisation, data analytics and energy-usage billing.

Sector Benefits

Building Flexible Shore Power Around Real Port Requirements

MJR's port power approach combines modular electrical infrastructure with marine engineering knowledge, allowing the system to be configured around the port, available supply and vessels using the berth.

Modular Quayside Deployment

Containerised power conversion can reduce the need for dedicated switch rooms and provides greater flexibility when integrating shore power into existing port or harbour infrastructure.

Flexible Vessel Integration

Power conversion and control can accommodate the differences between shore supplies and vessel electrical networks, supporting controlled transfer between onboard generation and shoreside power.

Energy Storage & Microgrids

Where grid supply is weak or variable, battery energy storage and mixed-source microgrids can be incorporated to store available energy and provide higher power when a vessel is alongside.

Reduced Generator Operation in Port

Once connected to a suitable shore power supply, vessel electrical loads can be transferred away from onboard diesel generation, reducing local exhaust emissions, noise and generator running while alongside.

How MJR Supports the Sector

A Connected Engineering Route from Feasibility to Operation

MJR can support a defined shore power work package or provide a wider route through electrical design, system construction, installation, commissioning and lifecycle support.

Consultancy & Design

Electrical engineering for port and shore power projects including feasibility, FEED, concept and detailed design, system modelling, load studies, protection studies, specifications and integration planning.

Engineering & Construction

Engineering and construction of shore power equipment, power conversion systems, switchboards, control panels, energy storage and associated automation for new and retrofit infrastructure.

Installation & Commissioning

Site installation, cabling, termination, testing, system integration and commissioning across new port infrastructure and retrofit applications.

Service, Repair & Testing

Lifecycle support for switchgear, converters, power electronics, automation and associated port electrical equipment, including fault finding, testing, maintenance and upgrades.

Typical Applications

Port Power and Charging Across New and Existing Berths

MJR's port electrical engineering capability can be applied across different berth, vessel and grid conditions, from straightforward shore-to-ship supply through to integrated charging and energy-storage infrastructure.

Existing Berth Shore Power

Retrofit shore power systems for existing quaysides where ports need to provide vessel power without constructing a completely new electrical building or berth infrastructure.

Ferry & Workboat Charging

Shore power and charging infrastructure for ferries, workboats and other hybrid or electric vessels operating regular routes or predictable berth cycles.

Multi-Berth Port Electrification

Scalable power-conversion, control, metering and monitoring infrastructure designed to support multiple vessels, berth arrangements or future expansion.

Constrained-Grid & Remote Ports

Energy storage and microgrid configurations for sites where the local electrical network cannot economically deliver full vessel demand directly at all times. MJR's QuayPower architecture specifically supports grid, renewable generation, battery storage and backup sources in these applications.
