  • Coverage: India, UAE, Singapore, Europe & all major naval & commercial ports

Naval auxiliary and coast-guard patrol craft — fast patrol boats, cutters, offshore patrol vessels (OPVs) and support, supply and replenishment ships — run hard-driven commercial-diesel propulsion plants that demand reliable, fast-moving spare parts. The propulsion packages we support span high-speed diesels such as the MTU 396, 4000 and 8000 series, medium-speed Pielstick PA6B and PC2-6 units, Caterpillar 3500 and C32 engines, and MAN four-stroke main and auxiliary diesels. Many of these vessels run CODAD or CODAG arrangements through Renk or ZF reduction gearboxes onto controllable-pitch propellers or water-jets, so we stock and source injectors, turbocharger cartridges, bearings, clutch packs, gears, seals and complete overhaul kits. Wattmare supplies the engine-room consumables and rotating-machinery spares that keep these hulls available for patrol, fisheries protection, search-and-rescue and fleet-support duty.

Working beside the Alang ship-recycling yard in Bhavnagar, we combine three supply grades under one roof — genuine OEM parts, OEM-equivalent replacements built to original specification, and carefully reconditioned components recovered and refurbished from decommissioned vessels. For a coast-guard cutter waiting on a Pielstick fuel pump, an OPV needing ZF clutch friction plates, or a supply vessel chasing an MTU 4000 turbocharger, we quote against your engine and serial number and dispatch within 24–48 hours to any port worldwide. Beyond the main engines we cover shaft generators and auxiliary gensets, fin stabilisers, fuel and lube-oil purifiers, starting-air compressors and provision refrigeration plant — the full machinery spread of a patrol or auxiliary vessel, sourced and verified by people who handle these engines every day.

WHERE FAILURES HAPPEN AT SEA

A breakdown doesn’t wait for port.

The moments a naval & coast guard is most likely to need a part — and the spares we keep ready for each.

High-speed diesel injector & turbocharger wear — naval & coast guard spare parts | Wattmare

High-speed diesel injector & turbocharger wear

High-speed MTU and Caterpillar diesels run at high rpm and load, so injectors, injection pumps and turbocharger cartridges wear and lose efficiency over time. We supply matched injector sets, pump elements and turbo cartridge or bearing kits to restore power and clean combustion.

Reduction-gear & clutch wear — naval & coast guard spare parts | Wattmare

Reduction-gear & clutch wear

Renk and ZF reduction gears and their clutch packs take repeated engagement loads in manoeuvring and CODAD/CODAG operation, leading to worn friction plates, pitted gear teeth and tired bearings. We source clutch friction and steel plates, gears, pinions and thrust bearings to original specification.

CPP & water-jet seal & bearing wear — naval & coast guard spare parts | Wattmare

CPP & water-jet seal & bearing wear

Controllable-pitch propeller hubs and water-jet units suffer seal degradation, bearing wear and impeller erosion that cause oil loss and pitch or thrust problems. We supply hub seal kits, pitch-control spares, water-jet impellers, wear rings and shaft-seal assemblies.

Genset & switchboard reliability — naval & coast guard spare parts | Wattmare

Genset & switchboard reliability

Auxiliary gensets and their switchboards must hold up through long patrols, but injectors, alternator bearings, AVRs and breakers degrade with hours and load cycling. We supply genset diesel spares, alternator components and switchboard breakers, contactors and protection relays to keep power steady.

THE COMPLETE GUIDE

Naval & Coast Guard spare parts, explained.

One supplier for the whole patrol & auxiliary fleet

Sourcing parts for a mixed fleet of patrol boats, OPVs and support vessels usually means juggling separate suppliers for engines, gearboxes, propulsion, purifiers and refrigeration. Wattmare consolidates all of it under one point of contact, so your superintendent or procurement team places one enquiry instead of five.

That single channel covers MTU, Pielstick, Caterpillar and MAN diesels, Renk and ZF gearboxes, CPP and water-jet propulsion, gensets, stabilisers, purifiers and refrigeration. Fewer suppliers means tighter coordination, consolidated shipping and faster turnaround when a vessel is alongside on a short window.

One supplier for the whole patrol  auxiliary fleet — Wattmare

Genuine vs OEM-equivalent vs reconditioned

We quote three grades so you choose the right balance of cost and lead time for each job. Genuine OEM parts are ideal for class-critical or warranty work; OEM-equivalent replacements, built to original specification, cut cost on routine wear items; and reconditioned components recovered at Alang offer the fastest, most economical route for older or obsolete plant.

Every reconditioned part is inspected, cleaned, measured and function-tested before dispatch, and we tell you plainly which grade you are buying. For auxiliary and support vessels running long-service engines, the reconditioned and OEM-equivalent options often mean the difference between a vessel staying on task and one waiting weeks for new-build parts.

Genuine vs OEM-equivalent vs reconditioned — Wattmare

Real depth across patrol-craft machinery

Patrol and naval auxiliary vessels are not simply scaled-up workboats — they carry high-speed propulsion trains, CODAD/CODAG arrangements, complex gearboxes and dedicated power and stabilisation systems. We carry genuine depth across each of these: injectors and overhaul kits for MTU 396 / 4000 / 8000 and Pielstick PA6B / PC2-6, clutch and gear spares for Renk and ZF, and seal and bearing sets for CPP and water-jet units.

That depth extends to the supporting plant — shaft generators, auxiliary gensets, fin stabilisers, Alfa Laval and GEA purifiers, starting-air compressors and provision refrigeration. Whatever system is holding a vessel alongside, we can identify the part, confirm the specification against your serial number and source it quickly.
