Service Overview

A Complete Engineering Foundation for Marine and Offshore Projects

MJR Power & Automation provides in-house marine electrical design and engineering expertise across power, automation and electronic systems. Our engineers support projects from early-stage definition and FEED through concept development, specification production, detailed design, technical studies and class approval.

By maintaining engineering capability in-house, MJR can coordinate multiple disciplines through one delivery route and retain technical continuity as a project progresses into engineering, construction, installation and commissioning. This supports both focused design requirements and complex turnkey marine and offshore projects.

Who this is for Vessel owners, shipyards, offshore contractors, project engineers and technical teams requiring reliable project definition, coordinated marine electrical engineering and technically robust design outputs for newbuild, retrofit, upgrade or offshore projects.

Key Features

Engineering Support Across the Full Design Lifecycle

MJR's marine electrical design consultancy covers the engineering activities required to define, develop and verify marine and offshore electrical systems, with additional support for cost engineering and class approval.

FEED — Front End Engineering Design

Concept Design

Specification Production

Detailed Design

System Modelling

Safe & Hazardous Area Design

Protection & Discrimination Studies

FMEA / FMECA

Engineering Approach

In-House Expertise Connected Through One Delivery Route

MJR's in-house specialists combine marine electrical power, automation and electronic engineering within a coordinated project structure. This allows requirements, system interfaces, calculations and design decisions to be managed together rather than as disconnected work packages.

The same engineering knowledge can then remain with the project as it moves from concept and detailed design into construction, installation and commissioning, supporting continuity across the complete delivery lifecycle.

Project Definition

Establish operating requirements, existing-system constraints, technical interfaces and the objectives that will shape the design.

Multi-Discipline Engineering

Coordinate electrical power, automation and electronic engineering within one in-house design route.

Design Verification

Use modelling, calculations, protection studies and structured technical review to verify system integrity.

Class Approval Support

Develop the required engineering information and support class-review requirements where they apply to the project.

Technical Studies & Design Calculations

Calculations and Studies Aligned with Marine and Offshore Requirements

Whether the requirement covers a single circuit or a complete installation, MJR uses engineering studies and design calculations to verify electrical-system performance and support technically robust marine and offshore designs.

  • Load Balance Assessment of connected loads and expected operating demand.
  • Short Circuit Calculations Evaluation of prospective fault levels and equipment duties.
  • Volt Drop Calculations Verification of cable and electrical-distribution performance.
  • Busbar Strength Calculations Assessment of busbar performance under normal and fault conditions.
  • Harmonic Calculations Review of harmonic distortion and its impact on the electrical system.
  • Load Flow & Transient Stability Analysis of electrical-system behaviour during normal operation and changing conditions.
  • Protection & Discrimination Studies Coordination of protective devices to support selective fault isolation.
  • System Modelling Modelling of system behaviour to support technical decisions and design verification.
  • FMEA / FMECA Structured assessment of failure modes, their effects and, where required, their criticality.
  • Cost Engineering Assessment of engineering options alongside the cost implications of the developing design.

How It Works

A Clear Route from Early Definition to Approved Design

MJR can support the design process from the first definition of project requirements through engineering development, verification and preparation for client or class approval, with continuity into later delivery stages where required.

Step 001

Discover

Understand the vessel or asset, operating requirements, existing equipment, project constraints and key system interfaces.

Step 002

Define

Develop the project basis, FEED or concept design, system architecture, technical scope and specification requirements.

Step 003

Develop

Progress the agreed concept through detailed design, system modelling, calculations, technical studies and engineering documentation.

Step 004

Verify

Review system performance through calculations, protection studies, FMEA/FMECA and coordinated engineering checks.

Step 005

Approve

Prepare the design package for the required client and class review before progressing into construction, installation or commissioning.

Applications

Where Consultancy & Design Support Is Applied

For newbuild projects, MJR can support shipyards, vessel owners and project teams with FEED, concept development, system specifications and detailed marine electrical, power and automation design.

For retrofit and life-extension projects, engineering can begin with assessment of existing systems and interfaces before developing replacement or upgrade designs that integrate with retained vessel equipment.

For offshore and specialist equipment, MJR's electrical power, automation and electronic engineering capability can support the design and integration of complex equipment and systems from concept through to installation and commissioning.

Deliverables

Structured Information for Technical Evaluation

Consultancy and design outputs are developed around the requirements and stage of each project, providing the engineering information needed to support technical review, procurement, approval and subsequent delivery.

Design Basis & Project Definition

Defined operating requirements, technical scope, interfaces, constraints and design objectives.

Specifications & Detailed Design

Engineering specifications and developed design information for the systems within MJR's agreed scope.

Calculations, Models & Studies

Relevant load, fault, voltage-drop, harmonic, stability, protection, modelling and FMEA/FMECA outputs.

Approval & Project Documentation

Engineering information prepared to support client review, class approval and progression into construction, installation and commissioning.
