What MJR Power & Automation does

MJR Power & Automation is a UK-based marine electrical engineering specialist delivering turnkey design, procurement, construction, installation, commissioning and aftermarket service for commercial marine, offshore construction, and offshore renewable energy clients. Founded in 1975 and operating from facilities in Teesside (Stockton on Tees), the firm employs between 1 and 10 people and positions itself as a bespoke systems integrator rather than a product manufacturer, with its core branded offerings spanning Marine Automation, Shore Power, Offshore Power & Charging, and Motion Compensation, supported by a broader solutions catalogue covering marine propulsion, power generation and distribution, hybrid power, energy storage, modular offshore power and subsea power and control systems.

The company's commercial model is project-based enterprise sales: each engagement is scoped, engineered and built to vessel- or platform-specific requirements, with revenue earned across engineering consultancy, procurement and construction, installation and commissioning, and ongoing service, repair and testing work. Documented case-note engagements include a Parkol Green Isle trawler switchboard and automation package, ABB drive maintenance on the SS7 Seven Borealis class renewal, a drive and control retrofit on OSV Relume, and a turnkey VFD switchboard replacement on the Eni Douglas Oil Platform, evidencing capability across fishing, offshore support, and oil and gas segments.

MJR's technology stack is built around third-party OEM components (ABB, Danfoss, Siemens, Samsung, Hyundai are listed as trusted partners) integrated into marine-grade electrical power conversion and automation systems; there is no public evidence of proprietary software, AI/ML capability, or recurring SaaS revenue. Strategic direction is signalled by 2022 UK Government and 2023 Offshore Wind Growth Partnership grant support, indicating a deliberate capability build into offshore wind vessel services and decarbonisation-linked offerings such as shore power, hybrid power and energy storage, while the firm continues to serve its established commercial marine and offshore oil and gas customer base.

Direct peers

• Bakker Sliedrecht: Dutch marine electrical systems integrator delivering switchboards, drives, automation and power conversion for commercial marine, offshore and renewable clients. Closest direct comparable to MJR in scope, services and customer mix.
• Praxis Automation Technology: Marine automation, navigation and electrical engineering specialist supplying integrated bridge, propulsion control and power management systems — overlapping directly with MJR's marine automation, automation & control, and power generation offerings.
• Houlder Ltd: UK-based independent marine engineering consultancy and design house serving commercial marine and offshore energy, with capabilities in electrical and automation engineering analogous to MJR's consultancy and design service line.
• RH Marine: Dutch marine electrical integrator (formerly Imtech Marine) delivering system integration, switchboards, automation and bridge systems for naval and commercial vessels — a head-to-head peer for ship electrical installation, commissioning and field service.
• C-Job Naval Architects: Naval architecture and marine engineering firm with growing electrical and hybrid propulsion design capability; competes with MJR in early-stage design and consultancy for next-generation marine electrical systems.

Broad incumbents

• Kongsberg Maritime: Large marine technology incumbent providing automation, navigation, propulsion control and integrated electrical systems — overlaps with MJR's automation and propulsion offering but at vastly greater scale and as part of a full marine portfolio.
• Wärtsilä: Global marine engine, hybrid propulsion and lifecycle services incumbent whose Marine Power and Services businesses overlap with MJR's marine propulsion, hybrid power, energy storage and service offerings.
• ABB Marine & Ports: Major OEM for marine drives, propulsion, automation and shore power — both a key technology supplier to MJR and a competitor offering direct service, retrofit and digital solutions through its own global service network.
• Vard (Fincantieri): Specialised shipbuilder and marine engineering group within Fincantieri, delivering complex offshore and specialised vessels with integrated electrical packages — competes with MJR on turnkey vessel electrical scopes, but at much larger scale.

Regional players

• Tidal Marine: UK-based marine electrical engineering services provider focused on the British marine sector; comparable niche specialism to MJR though with a more UK-centric geographic focus.
