From routine oil-change kits to complete rebuilds of propulsion engines and gensets, our workshops utilize precision machinery—bore honing, crankshaft polishing, and injector balancing—to restore factory tolerances. Overhauls include alignment checks on shaft lines, vibration isolation mounting, and performance validation via dynamometer runs. Each overhaul is backed by a 12-month parts-and-labor warranty, ensuring uninterrupted onboard power and reliable passage-making capabilities.

Nautimech offers abrasive and hydroblasting cleaning options, followed by application of biocide-free silicone and fluoropolymer foul-release coatings. We conduct surface profile tests to guarantee optimal adhesion and recommend application thickness per vessel usage patterns. Post-application sea trials confirm reduced drag coefficients. Scheduled annual recoats maintain consistent performance, and our hull-performance data analytics provide ROI insights on fuel savings and maintenance costs.

We specialize in AC/DC switchboard fabrication, cable-lay audits, and battery-bank replacements. Generator synchronization, UPS integrations, and smart load-shedding are engineered for seamless power management. Our NMEA-2000 network installations enable digital monitoring of engine parameters, tank levels, and navigation data. Each electrical retrofit includes thermal imaging inspections to identify hotspots and tighten connections, ensuring fire safety compliance and system reliability.

Accredited composite technicians perform gelcoat repairs, core-material replacements, and full-section laminate rebuilds using vacuum-infused epoxy systems. Structural reinforcements—stringer replacements and bulkhead patching—are executed to Lloyd’s Register and DNV GL standards. Post-repair, ultrasonic thickness scans and moisture-content tests validate structural integrity, with third-party surveyor endorsements available upon request.

Liferaft hydrostatic release units, EPIRB battery replacements, and inflatable PFD inspections are managed under SOLAS and MCA guidelines. Fire-suppression systems—FM200, CO₂, and water-mist units—undergo pressure-testing and nozzle flow checks. We certify and tag all equipment, providing regulatory documentation and compliance training for crew to maintain readiness in emergencies.

Our carpentry team handles teak decking, joinery touch-ups, and interior layout modifications. AV and IT specialists integrate satellite communications, entertainment systems, and onboard Wi-Fi networks. Galley refits include refrigeration upgrades, induction cooktops, and bespoke cabinetry. HVAC system overhauls ensure climate control efficiency, while upholstery renewals refresh salon aesthetics. Each refit includes project planning, 3D renderings, and phased implementation to minimize downtime.
