MARINE BASED SERVICES
5. MARINE HARNESS ASSEMBLY
At Magnitude Electrical Services, we specialise in the assembly of high-quality marine cable harnesses and electrical looms for the marine and maritime industry.
Modern vessel builds and refits are increasingly moving towards pre-manufactured electrical assemblies, reducing the amount of onboard manufacturing and installation time required during the build process. By carrying out as much work as possible off the vessel, projects benefit from improved build quality, faster installation, reduced labour costs, and better overall consistency.
We support this approach by manufacturing bespoke, installation-ready harnesses and assemblies tailored to each project’s requirements.
This includes:
- Main vessel cable harnesses and looms
- Multi-branch power and signal harnesses
- Pre-made battery connections and power cables
- Bespoke NMEA cables and adaptors
- Custom ethernet and data cables
- Control and interface wiring assemblies
- Connector termination and breakout assemblies
- Labelled and tested installation-ready cable sets
Harnesses and assemblies can be supplied fully labelled, protected, and ready to install directly onboard, helping significantly reduce onsite labour and simplifying integration for installers and shipyards.
We can work from customer-supplied drawings and BOMs, or provide a complete turnkey solution including design support, component sourcing, assembly, testing, and installation support where required.
Our assemblies are produced in-house using professional tooling and equipment, with a strong focus on neatness, reliability, and durability within demanding marine environments.
Benefits of off-vessel harness manufacturing include:
- Reduced onboard installation time
- Lower labour costs during vessel build or refit
- Improved installation consistency and quality
- Reduced risk of wiring errors onboard
- Cleaner and more organised installations
- Faster commissioning and fault finding
- Simplified future maintenance and replacement
We work to high workmanship standards, including IPC/WHMA-A-620 practices, ensuring all harnesses and assemblies are produced with quality and reliability in mind.
Whether supporting a one-off refit project, prototype system, or ongoing vessel production programme, Magnitude Electrical Services can provide tailored marine harness assembly solutions designed to streamline installation and improve efficiency throughout the build process.
