The complete guide

IHI turbocharger spare parts, explained

Wattmare is a specialist IHI turbocharger spare parts supplier serving India, the UAE, Singapore and the wider global fleet. From our base in Bhavnagar — beside the Alang ship-recycling yard — we supply genuine, OEM-equivalent and reconditioned spares for every generation of IHI two-stroke marine turbocharger, dispatched worldwide in 24–48 hours.

The IHI lineage

IHI turbochargers are designed and built by Ishikawajima-Harima Heavy Industries of Japan, one of the country’s oldest heavy-engineering groups. The AT and RH series have powered marine engines worldwide for decades. We supply spares across all of them.

AT versus RH versus SeaTrust series

The single most important question on any IHI order is whether the engine is an AT, an RH or an SeaTrust series. The IHI AT is classic — lube-oil pump, fuel cam, shaft seal and mechanical bearing gear. The RH / RH and the IHI SeaTrust series are electronically controlled, replacing the rotor with a high-efficiency supply unit, sealing rings, sealing-air parts and hydraulically actuated bearings. Cartridges, casings, compressor wheels and bearings are broadly common by frame size, but injection and actuation parts are entirely different — always give us your exact AT / RH / SeaTrust series designation.

Four-stroke: the IHI medium-speed range

Alongside the two-strokes, IHI’s medium-speed four-stroke engines power gensets and auxiliary sets. The range — IHI AT, RH and SeaTrust turbochargers, plus the V-versions — is among the most installed auxiliary engines afloat. While this page focuses on the marine turbochargers, we also supply rotor shafts, compressor wheels, cartridges, valves, nozzle rings, lube-oil pumps and bearings for these four-strokes.

The Alang advantage for legacy AT parts

Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing IHI AT two-stroke engines. That gives Wattmare direct access to genuine, low-hour parts that are slow or costly to source from distributors, at a fraction of new-part cost and lead time. For hard-to-find AT lube-oil pumps, shaft seals, cartridges or rotating assembly, this is the fastest source in the world. Browse our reconditioned marine spare parts range, the wider turbocharger spare parts category, or sister brands like MAN engine spares and Mitsubishi UEC.

How to order and what to expect

Send your IHI engine make and model with a photo or part number on WhatsApp, or use the quote form. We confirm availability and price — usually within the hour — and dispatch in-stock items within 24 hours. Typical air-freight transit is 12–18 hours to the UAE, 16–24 to Singapore, 20–26 to Greece and Turkey, and 28–36 to Northern Europe.

FAQ

IHI parts,
answered.

Do you supply IHI AT turbocharger cartridges?

Yes — turbocharger cartridges are one of our strongest IHI lines. We carry genuine and reconditioned cartridges for the AT and RH series, plus the rest of the AT range (AT14 to AT80), honed to OEM tolerance with measurement reports. Most legacy AT cartridges are recovered and reconditioned beside Alang.

What is the difference between IHI AT, RH and SeaTrust series parts?

The IHI AT is a classic (mechanical) two-stroke — lube-oil pump, fuel cam and mechanical bearing actuation. The RH / RH and the IHI SeaTrust series are electronically controlled, replacing the rotor with a high-efficiency supply unit, sealing rings, sealing-air parts and hydraulically actuated bearings. Cartridges, compressor wheels and bearings are broadly similar by frame size, but the injection and bearing actuation parts are completely different — always quote your exact AT, RH or SeaTrust series model.

Which IHI engine models do you cover?

We cover the full two-stroke range — the current IHI SeaTrust series (SeaTrust, SeaTrust, SeaTrust, SeaTrust, SeaTrust, SeaTrust, SeaTrust), the high-efficiency RH / RH (the RH and SeaTrust range) and the legacy IHI AT (AT14 up to AT80, including the RH and SeaTrust variants) — every IHI AT, RH and SeaTrust frame size. We also supply the four-stroke medium-speed IHI AT, RH and SeaTrust turbochargers.

Are reconditioned IHI parts class-approved?

Reconditioned parts ship with inspection reports, dimensional measurements and photographs, and are accepted by class societies (Lloyd’s Register, DNV, ABS, BV, ClassNK, RINA) on survey. Genuine IHI parts carry full material and test certificates.

How fast can you deliver IHI parts to Dubai?

In-stock items dispatch within 24 hours from Bhavnagar. Typical air-freight transit to the UAE (Dubai, Jebel Ali, Fujairah) is 12–18 hours. Singapore is 16–24 hours, Greece and Turkey 20–26, and Northern Europe 28–36.

Can you supply IHI nozzle rings and lube-oil pumps?

Yes — nozzle rings, injector nozzles, high-pressure lube-oil pumps, plungers and barrels for IHI AT engines, plus high-efficiency supply units, sealing rings, sealing-air parts and injection equipment for RH / RH and SeaTrust series engines, are stocked and bench-tested before dispatch.

What is the difference between genuine, OEM-equivalent and reconditioned parts?

Genuine parts come from the original maker (IHI / IHI) with full certificates. OEM-equivalent are quality aftermarket parts at 30–50% less. Reconditioned are low-hour parts recovered from Alang, inspected and certified to OEM tolerance, at up to 70% less with a 30-day warranty.

Do you supply obsolete IHI AT parts no longer stocked by distributors?

Yes — obsolete IHI AT parts are our specialty. Beside Alang we recover low-hour lube-oil pumps, shaft seals, cartridges and wheels and rotating assembly from AT-powered vessels being dismantled, then inspect and certify them. For the AT and RH range and AT engines this is often the fastest source in the world.

Do you carry IHI RH, SeaTrust and AT turbocharger spares?

Yes — rotor, cartridge and bearing spares for the four-stroke medium-speed IHI AT, RH and SeaTrust turbochargers, including rotor shafts, compressor wheels, cartridges, nozzle rings and bearings, fuel equipment and bearings for gensets and auxiliary engines.

How do I get a price for a IHI spare part?

Send your engine model and a photo or part number on WhatsApp (+91 96647 18068), or use the quote form. We confirm availability and price, usually within the hour — whether you need genuine, OEM-equivalent, used or reconditioned parts, or a complete service kit.

Where do you ship IHI parts and how are they packed?

We ship from Alang/Bhavnagar to the UAE, Dubai, Singapore, Greece, Turkey and every major port worldwide in 24–48 hours. Parts are export-packed with VCI wrapping, wooden crates and palletisation, with photos shared before dispatch and full export documentation included.

Can you supply complete IHI service kits?

Yes — bearing-service, cartridge-exchange and full-service kits assembled to your exact AT, RH / RH or SeaTrust series model, with cartridges, sealing rings, nozzle rings, bearing assemblies, shaft-seal rings, gaskets, O-rings and fasteners included.
