MARINE BASED SERVICES
6. MARINE INFRASTRUCTURE & SHORE SIDE ELECTRICAL SERVICES
At Magnitude Electrical Services, we provide specialist electrical solutions for marine infrastructure projects including marinas, dry docks, shipyards, pontoons, fixed barges, shore power systems, and generator installations.
We have extensive experience working within operational marine environments and understand the challenges involved in restoring, upgrading, and maintaining ageing waterfront electrical infrastructure while keeping facilities operational wherever possible.
Our experience includes marina electrical upgrades, dry dock restorations, dockside power distribution, vessel charging infrastructure, temporary supplies, generator installations, and shipyard electrical systems.
Marine environments place unique demands on electrical installations due to saltwater exposure, corrosion, vibration, UV exposure, and harsh operating conditions. We design and install systems with durability, reliability, and maintainability at the forefront.
Our capabilities include:
- Marina and shipyard electrical infrastructure
- Dry dock electrical systems
- Shore power and vessel charging systems
- Temporary and permanent generator installations
- Pontoon and fixed barge power distribution
- LV distribution systems and switchboards
- Heavy-duty cable containment and routing systems
- Industrial and emergency lighting
- Control panels and automation systems
- Electrical design, schematics, and load calculations
- Testing, inspection, and commissioning
We regularly work within live marinas, shipyards, and dock environments, coordinating installations around vessel movements, tidal conditions, restricted access, and ongoing operations.
We have practical experience with:
- Installation of high-current shore power systems
- Generator integration and temporary power arrangements
- Synchronisation and changeover systems
- Large submain and feeder cable installations
- Armoured and marine-grade cabling systems
- Protection coordination and breaker sizing
- Load balancing and diversity calculations
- Cable routing across pontoons, piers, dry docks, and marine structures
- Installation of tray, ladder, Unistrut, cleating, and support systems
- Upgrading ageing and legacy dockside electrical infrastructure
- Future-proofing installations for additional vessel charging capacity
Our approach focuses on delivering practical, reliable electrical systems designed specifically for demanding marine environments, ensuring installations remain safe, maintainable, and fit for long-term operation.
Whether supporting a marina upgrade, dry dock restoration, shipyard project, generator installation, or new shore power installation, Magnitude Electrical Services can provide tailored marine electrical solutions from design through to installation and commissioning.
