Shipyards and Newbuilds
Shipyard electrical engineering from concept and detailed design through switchboard construction, automation, onboard installation and commissioning for newbuild vessels.
Sector Overview
Electrical Engineering That Connects Design, Build and Vessel Delivery
Newbuild programmes require electrical power, propulsion, automation and control systems to be engineered as part of the wider vessel from the outset. Equipment selection, load requirements, interfaces, classification requirements, installation routes and vessel operating philosophy all influence the final electrical architecture.
MJR works with shipyards, naval architects, vessel owners and project teams across the newbuild lifecycle. Support can include system specifications, electrical architecture, single-line diagrams, calculations and detailed design through to switchboard and control-panel construction, power management, automation, installation, integration, testing and commissioning. MJR's newbuild capability also covers common AC and DC bus systems, variable-speed generation, hybrid and electric power, energy storage and shore or offshore charging integration.
Who MJR supports Shipyards, naval architects, vessel designers, project managers, vessel owners, operators and procurement teams requiring a specialist marine electrical engineering partner for a complete newbuild package or a defined electrical, power or automation work scope.
Sector Challenges
Coordinating Complex Electrical Systems Within the Newbuild Programme
A successful vessel electrical package depends on more than individual pieces of equipment. Power generation, distribution, propulsion, automation, auxiliary systems and third-party equipment need to be coordinated around the vessel design and build programme.
Greater Layout Flexibility
Cabling operating modes, technical requirements, interfaces and project constraints.
Improved Damage Resilience
Combining electrical power, automation and electronics engineering within one coordinated scope.
Higher Reliability
Using calculations, studies and structured review to protect system integrity.
More Efficient Operation
Maintaining technical knowledge from initial concept through build, installation and commissioning.
Lower Emissions and Noise
Integrating efficient power generation, hybrid and electric technologies to reduce fuel consumption, emissions and onboard noise.
Sector Benefits
Reducing Interfaces from Design Through to Commissioning
Keeping electrical design, construction, automation and installation connected gives shipyards and vessel owners a clearer engineering route from the original specification through to an operational vessel.
Coordinated System Engineering
Power generation, distribution, propulsion, automation and control can be considered together rather than developed as disconnected work packages.
Build-Ready Engineering
Detailed drawings, calculations, specifications and interface information give workshop and vessel-installation teams the information needed to progress construction and integration.
Integrated Testing
Switchboards, control systems, software and associated equipment can be assembled and tested before final onboard integration, helping identify interface issues earlier in the delivery programme. MJR's project history includes factory acceptance testing with client and class before vessel installation.
Continuity Through Installation
The engineering knowledge developed during design and construction remains available during onboard installation, commissioning and troubleshooting.
