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.
