Installation & Commissioning
Marine electrical installation and commissioning for newbuild, retrofit and offshore projects, covering power, control, communications and auxiliary systems from site preparation and cable installation through testing, integration and handover.
Service Overview
Experienced Installation for Marine and Offshore Electrical Systems
MJR Power & Automation provides marine electrical installation, integration and commissioning support for vessels, offshore equipment and specialist marine projects. Installation teams work across systems designed and built by MJR as well as a wider range of third-party equipment.
Retrofit and life-extension projects can involve limited installation windows, existing equipment, restricted access and short testing periods. MJR's installation capability covers equipment removal, power and control cabling, communications, auxiliary systems, subsea cable work, earthing, lighting and associated testing.
Who this is for Shipyards, vessel operators, offshore contractors, cable-lay and subsea project teams, technical superintendents and project engineers requiring reliable installation, system integration and vessel electrical commissioning for newbuild, retrofit or mobilisation projects.
Key Features
Marine Electrical Installation Across Power, Control and Vessel Systems
MJR's installation capability covers electrical equipment removal and retrofit work through to power, instrumentation, communications and vessel auxiliary systems, with installation, termination and testing carried out around the requirements of each project.
Retrofit & Equipment Removal
Site and offshore surveys, dry-dock preparation and removal of obsolete equipment ahead of system replacement or upgrade.
LV & HV Power Cabling
Installation, termination and testing of low-voltage and high-voltage marine power distribution cabling.
Subsea Cable Installation
Installation and preparation of subsea power and fibre-optic cabling for offshore applications.
Cable Testing
Testing support across relevant stages of cable load-out, lay, pull-in, hang-off, burial and termination.
Instrument & Control Cabling
Installation, termination and testing of cabling for instrumentation and control systems.
Communications & Network Cabling
Marine communications, network and fibre-optic cabling installation and testing.
Vessel Auxiliary Systems
Installation of CCTV, PA, telephone, auxiliary, bridge and navigation equipment.
Earthing, Lighting & Small Power
Installation and testing of earthing systems alongside vessel lighting and small-power systems.
Installation & Commissioning Approach
Site Delivery Built Around Vessel and Project Constraints
Marine electrical installation often has to be completed around vessel access, dry-dock schedules, existing systems and other project activities. MJR approaches each installation by first understanding the equipment, interfaces, cable routes and programme before progressing into installation and system integration.
Survey & Planning
Review the vessel, equipment, installation environment, cable routes, interfaces and project programme.
Installation & Integration
Install equipment and connect new systems into the vessel or offshore asset while coordinating with existing infrastructure.
Testing & Commissioning
Test installed cabling, equipment and system interfaces before progressing through the agreed commissioning requirements.
Documentation & Handover
Provide the relevant testing and commissioning records required by the agreed project scope.
Installation, Cabling & Testing
Practical Installation Capability from Equipment Removal to Final Testing
MJR supports the physical installation and connection of marine and offshore electrical systems across power, control, communications and auxiliary equipment, including specialist marine cable installation and testing requirements.

- Instrument & Control Systems Install and terminate instrumentation and control-system cabling between field equipment, panels and associated systems.
- Earthing, Lighting & Small PowerInstall and test vessel earthing systems, lighting circuits and small-power infrastructure as part of wider marine and offshore electrical installation works.
- Comprehensive Cable Testing Test cable systems through load-out, laying, pull-in, hang-off, post-burial and final termination stages.
- Communications & Network Cabling Install, terminate and test marine communications and network cabling for reliable vessel and offshore system connectivity.
- CCTV, PA & Telephone Systems Install CCTV, public address and telephone systems as part of wider vessel electrical and communications packages.
- Bridge & Navigation Equipment Install and connect bridge and navigation equipment alongside associated electrical and communications infrastructure.
- Cable Jointing Complete cable jointing as part of marine and offshore electrical installation, retrofit and cable-integration work.
How It Works
A Controlled Route from Site Survey to Commissioned System
Each project is adapted to the vessel, equipment and programme, but MJR's installation work follows a clear progression from planning and preparation through installation, testing and project handover.
Step 001
Survey
Review the vessel or offshore asset, existing systems, installation environment, access restrictions, cable routes and interfaces.
Step 002
Prepare
Define the installation requirements, coordinate the programme and prepare for equipment removal, cable routing and system integration.
Step 003
Install
Install equipment and complete marine power, instrument, control, communications and auxiliary cabling as required by the project.
Step 004
Test & Commission
Test installed equipment, cabling and interfaces and progress through vessel electrical commissioning and agreed FAT, SAT or witnessed testing requirements where applicable to the project scope.
Step 005
Handover
Complete the agreed testing and commissioning records and prepare the installed system for operational handover and ongoing support.
Applications
Where Installation & Commissioning Support Is Used
Vessel Newbuilds
Shipyards and vessel builders can use MJR for marine electrical installation, cabling, system integration, testing and commissioning alongside the wider engineering and construction package. MJR's Green Isle project, for example, included onboard installation, cabling, testing and certification of the newbuild electrical package.
Retrofit & Life-Extension Projects
Existing vessels frequently require obsolete equipment to be removed and replacement systems integrated with retained equipment inside constrained dry-dock or operational windows. This is a core application identified on MJR's live installation page.
Offshore Mobilisation & Cable Projects
MJR supports offshore electrical commissioning, equipment mobilisation and specialist cabling for offshore construction, cable-lay and subsea applications. Recent projects include the Prysmian Monna Lisa HydroPlow mobilisation, Prysmian Ulisee AHC crane installation and T3200 trencher mobilisation.
Deliverables
Installed, Tested and Integrated Electrical Systems
The final delivery package depends on the project scope, but installation and commissioning work can combine installed equipment, completed cable systems, testing records and commissioning documentation.
Installed Equipment & Systems
Electrical equipment and associated vessel or offshore systems installed in accordance with the agreed project scope.
Completed Cabling & Terminations
Power, instrumentation, control, communications and auxiliary cabling installed, terminated and prepared for operation.
Testing & Commissioning Records
Relevant inspection, testing and commissioning information generated through the agreed delivery process.
Project Handover
Completed installation prepared for client handover, certification or further operational support as required by the project.
The exact deliverables are established around the vessel, equipment, installation scope, testing requirements and any project-specific class or witness requirements.
