Marine Electronic Repair — UK Wide | Newcastle Upon Tyne
Marine Electronics Repair UK |
Vessels, Drives & Control Systems
Marine electronic failures cause vessel downtime, missed schedules, and costly OEM call-outs. We repair propulsion drives, deck machinery controls, engine room PCBs, and power management electronics at component level — faster and cheaper than replacement.
Marine electronic equipment operates in demanding conditions — salt air, moisture, vibration, and temperature extremes that accelerate component failure. We specialise in component-level repair of marine drives, control boards, and power electronics, returning equipment tested and ready for service. No OEM call-out charges. No long lead times for new parts that may not exist.

Marine electronic faults we diagnose and repair
Marine electronic failures have specific causes. The marine environment is hostile to electronics — we understand what that means at component level.
Salt air and moisture create conductive paths across PCBs, causing tracking faults and component failure. We carry out chemical wash, clean the board, and repair damage at component level.
Condensation and water ingress into drive enclosures and control panels cause short circuits and corrosion on PCBs and power components. We identify all affected areas before repair begins.
Failed IGBTs and power modules in propulsion drives and thruster controllers — the most common cause of drive failure. Identified and replaced at component level.
DC bus and filter capacitors in marine drives degrade faster in high-humidity environments. Replaced as part of repair or during scheduled refurbishment.
Vessel vibration causes solder joint cracking, component fractures, and connector failures on PCBs. We identify vibration-related damage and repair or reinforce affected joints and components.
Repeated heating and cooling cycles in marine environments cause solder fatigue and BGA failures on control boards. Root cause identified before component replacement.
Power quality issues and surges in marine electrical systems cause drive and control board damage. We identify the extent of damage and repair the affected components.
Older vessels carry drive systems and control boards the OEM no longer supports. We repair obsolete marine electronics at component level, sourcing or substituting discontinued parts.
Chemical wash and cleaning for marine boards
Marine PCBs and control boards arriving at our workshop often carry significant contamination — salt residue, corrosion, biological growth, and general ingress from the marine environment. Before any fault diagnosis begins, contaminated boards are cleaned and dried to ensure accurate assessment and lasting repair.
Chemical cleaning removes surface contamination that would otherwise cause repeat failures after repair. Where conformal coating has broken down, we reapply it after repair to protect the board against the marine environment going forward.
- Ultrasonic and chemical wash to remove salt, flux, and biological contamination
- Inspection under magnification after cleaning to identify corrosion damage
- Conformal coating assessment and reapplication where required
- Moisture damage assessment before and after drying
Our marine electronic repair process
Receive, log & inspect
Equipment is logged on receipt and inspected for physical damage, contamination, and signs of environmental exposure. We note the condition before any work is carried out — important for your maintenance records.
Clean & prepare
Contaminated boards and equipment are cleaned before fault diagnosis begins. Salt, moisture residue, and corrosion are removed. This step ensures accurate diagnosis and prevents contamination from causing repeat failures.
Component-level fault diagnosis
We diagnose the fault at component level — not by substituting boards until one works. We identify exactly what failed and why, including any underlying cause that would trigger repeat failure if left unaddressed.
Written quotation
A written quote is provided covering all work required. If the equipment is beyond economic repair, we tell you clearly with a full explanation — so you can make an informed decision about replacement.
Repair & component replacement
Faulty components are replaced to the original specification. Power sections, control boards, capacitors, IGBTs, and connectors are replaced as required. Conformal coating is reapplied to marine boards after repair.
Functional testing & return
Repaired equipment is tested under load conditions before return. We do not return equipment until it has passed functional testing and we are confident it will perform in service. A full repair report is provided.
Marine drive & electronics manufacturers we repair
Vessel types we support
We carry out marine electronic repair for vessel operators, fleet managers, and shipyards across the UK. Any vessel with industrial electronic equipment — we can help.
OSVs, PSVs, and AHTS vessels operating in the North Sea and beyond. Drive systems, DP electronics, and deck machinery controls.
Bulk carriers, container ships, tankers, and general cargo vessels. Engine room controls, cargo handling drives, and power management electronics.
RoPax ferries, passenger ferries, and cruise support vessels. Propulsion drives, thruster controls, and passenger services electronics.
Trawlers, pelagic vessels, and fish factory ships. Winch drives, refrigeration controls, and engine room PCBs.
Trailing suction hopper dredgers, cutter suction dredgers, cable layers, and survey vessels. Specialist machinery drive systems.
Harbour tugs, anchor handling tugs, and offshore workboats. Propulsion and deck machinery controls.
New-build fit-out, refit, and drydock maintenance. We work with shipyards on electronics for both new build and in-service vessel maintenance.
Crew transfer vessels (CTVs), SOVs, and jack-up installation vessels operating in the offshore wind sector.
Why marine operators choose NPE
OEM repair costs are high. Lead times for new marine electronics are long. Component-level repair is the faster, cheaper alternative — and we do it properly.
We find and fix the fault — we don't replace the whole board hoping that resolves it. Component-level repair costs significantly less and preserves your original configuration.
Older vessels carry drive systems and control boards the OEM discontinued years ago. We repair legacy marine electronics other companies won't take on, sourcing or substituting discontinued components.
Vessel downtime is expensive. We assess incoming equipment quickly and contact you with findings and a written quote without delay. No waiting weeks for an OEM engineer.
We know what salt, moisture, and vibration do to marine electronics at component level. Our diagnosis accounts for marine-specific failure modes — not just standard bench faults.
Every repair is documented. Every unit is functionally tested before return. Our ISO 9001 certification supports your maintenance record-keeping and vessel audit requirements.
We are a recognised supplier to the offshore and energy sector through our NOF membership. Our engineers understand the documentation and quality requirements of the offshore maritime industry.
Frequently Asked Questions
Do you repair electronics from marine vessels and ships?
Yes. We repair marine electronic equipment from commercial vessels, offshore support vessels, ferries, fishing vessels, and shipyards across the UK. Equipment is sent to our Newcastle workshop by courier, or we can arrange collection for larger or heavier items.
What types of marine electronic equipment do you repair?
We repair propulsion drives, bow and stern thruster controllers, deck machinery drives (winches, capstans, cranes), engine room PCBs and control boards, power management system electronics, marine inverters, UPS boards, and bridge control electronics.
Can you repair marine electronics that have suffered corrosion or moisture damage?
Yes. Corrosion and moisture contamination are among the most common causes of marine electronic failure. We carry out chemical wash and cleaning, assess the extent of damage, repair affected components, and reapply conformal coating where required.
Can you repair obsolete marine drives and control systems on older vessels?
Yes. Older vessels frequently carry discontinued drive systems and control electronics the OEM no longer supports or stocks parts for. We repair obsolete marine drives and boards at component level, sourcing or substituting discontinued components where required.
How quickly can you assess a marine electronic fault?
We assess incoming marine equipment within 1–2 working days of receipt and contact you with our findings and a written quote. We understand vessel downtime is costly and we prioritise a fast, clear response.
Is it cheaper to repair marine electronics than to buy new?
In most cases, significantly cheaper — repair typically costs 20–40% of a new unit. For obsolete marine equipment, there may be no new replacement available at any price. Even for current equipment, repair avoids the long OEM lead times that can keep a vessel out of service.
