— Overview

Specialist turbocharger spares, at the source in Alang.

Wattmare supplies spare parts for marine exhaust-gas turbochargers — the single-stage units that boost every two-stroke and four-stroke marine diesel. We hold genuine, OEM-equivalent and reconditioned rotor assemblies, nozzle rings, bearings and complete cartridges for all major makes and dispatch them to any port worldwide in 24–48 hours.

Because our base in Bhavnagar sits beside the Alang ship-recycling yard, we recover and restore turbocharger rotors, nozzle rings, bearings and cartridges from decommissioned engines — a faster, cheaper route to keeping tonnage running than OEM lead times that stretch into months. Every reconditioned rotor is balanced, crack-tested and supplied with a report.

For high-wear cartridges recovered from ships dismantled at Alang, see our reconditioned marine spare parts; for a vessel down with a turbocharger surge or bearing failure, our emergency marine spare parts desk dispatches within 24–48 hours; and for the full sourcing story, our Alang ship spare parts guide.

Holset spare parts

Holset (Cummins Turbo Technologies) builds radial turbochargers for marine and genset diesels — the HX, HT and HC ranges. Note a real failure mode: HT4B, HT4C and HT80 rotate opposite to HC/HX units, so their turbine and compressor wheels must never be interchanged. We supply cartridges, wheels, bearings and repair kits.

Buyer's guide

How to order the right turbocharger part.

Six steps from a worn component to the correct part crated for your vessel — the workflow our desk uses on every enquiry.

01

Identify the unit

Read the nameplate on the turbocharger or in the ship's papers — maker, series and frame number. Licence-built units use the identical OEM nomenclature, so the plate never limits sourcing.

02

Pin the exact part

Give the OEM part number if you have it, or a clear name plus key measurements. A nameplate photo and a photo of the worn part are the fastest route to a firm quote.

03

Choose the grade

Match provenance to criticality — Alang-reconditioned for high-wear and legacy items, OEM-equivalent for consumables, genuine for class-critical parts. All three meet the maker's tolerances.

04

Confirm class needs

Tell us the vessel's classification society if the part must be presented for survey — we supply maker/material certificates on new parts and measurement/NDT reports on reconditioned parts.

05

Plan the lead time

Planned-maintenance orders ship on schedule; for a breakdown our emergency desk dispatches in 24–48 hours to any major port.

06

Get a firm quote

Send it all on WhatsApp. We check stock and our Alang-sourced pool, confirm condition and price, and reply — usually the same day.

Alang reconditioning

Turbocharger cartridges,
recovered and restored.

The turbocharger is one of the highest-value parts recovered at Alang. We strip, clean, measure and re-machine rotors, nozzle rings and bearings to the maker's limits, then dynamically balance and crack-test every rotor before it ships.

How Alang reconditioning works
Step 1

Strip & clean

The cartridge is dismantled, grit-blasted and chemically cleaned so every surface can be inspected.

Step 2

Measure to limit

Rotor, wheels, nozzle ring and bearings are measured against the maker's dimensional limits.

Step 3

Crack-test

Rotor and wheels are dye-penetrant / magnetic-particle crack-tested; cracked parts are rejected, not repaired.

Step 4

Re-machine

Worn journals, seal grooves and faces are restored to OEM tolerance; parts outside limit are replaced with genuine or OEM-equivalent.

Step 5

Balance

The assembled rotor is dynamically balanced to grade — mandatory after any rotor work to avoid vibration and bearing failure.

Step 6

Document & crate

The cartridge ships with a measurement and NDT report, tagged with its frame and traceable batch.

Overhaul & inspection

When each turbocharger part is due.

Turbocharger overhaul follows the engine maker's schedule and the unit's running hours and fuel quality — not a fixed figure. This is the typical order of what wears, what we inspect and the usual action, so you can plan the parts before the survey.

Symptoms & causes

Common turbocharger faults.

The symptoms our desk is asked about most — and the parts they usually point to. Send the frame number and a photo of the fault for a firm quote on the parts to fix it.

compressor wheel of marine turbocharger
Airflow instability

Compressor surge / hunting

A bark or hunting under load — often fouling, a worn nozzle ring or wrong matching. Check the compressor wheel and nozzle ring.

compressor wheel of marine turbocharger
Lost efficiency

Low boost / fouled compressor

Falling scavenge pressure and rising fuel — usually a fouled or eroded compressor wheel and dirty filter-silencer.

turbine rotor of marine turbocharger
Turbine side

High exhaust temperature

Rising exhaust temperatures point to a fouled turbine, eroded nozzle ring or dropping turbocharger speed.

nozzle ring of marine turbocharger
Poor fuel

Eroded nozzle ring

Vane erosion from low-quality fuel cuts turbine efficiency. Renew the nozzle ring; consider anti-erosion coating.

bearing of marine turbocharger
Lube / wear

Bearing knock or failure

Metallic knock, high vibration or metal in the oil — inspect the journal and thrust bearings and the oil supply.

rotor of marine turbocharger
Balance

Rotor vibration / imbalance

Vibration after a wheel change or deposit build-up. The rotor must be dynamically re-balanced before return to service.

gas-side seals of marine turbocharger
Seals

Gas-side leakage

Exhaust past the seals fouls the bearings and lube oil — renew the labyrinth and sealing-air rings.

cartridge and seals of marine turbocharger
Sealing

Oil leakage / seal wear

Oil into the gas or air side signals worn seals or wrong oil pressure. Fit a seal kit and check the supply.

Questions, answered

Marine turbocharger spares — your questions.

The questions technical managers and chief engineers ask us most about turbocharger parts.

Which marine turbocharger brands do you supply spare parts for?
ABB / Accelleron (VTR, TPL, TPS, A100/A200), Mitsubishi MET, Napier, IHI, KBB, MAN (TCA/TCR/NA/NR) and Holset. For each we supply rotor assemblies, nozzle rings, journal and thrust bearings, compressor wheels, complete cartridges and service kits — genuine, OEM-equivalent and Alang-reconditioned.
Do you still supply parts for the legacy ABB VTR series?
Yes. The ABB VTR..4 series (VTR214 through VTR714) is legacy but fully supported — Accelleron still provides original spares and service, and we hold and recondition VTR rotors, nozzle rings, bearings and cartridges. Send the exact VTR frame number from the nameplate for a firm quote.
What is a reconditioned turbocharger cartridge and how much does it save?
A reconditioned cartridge is a genuine rotor, bearing set and nozzle ring recovered from a decommissioned engine, re-machined to the maker's limits, dynamically balanced and crack-tested. It typically costs 30–60% less than a new OEM cartridge, with the largest saving on high-value and legacy frames. Every unit ships with a measurement and NDT report.
Can you supply a complete turbocharger cartridge for a vessel down?
Yes — a balanced, bolt-in cartridge is the fastest route back to service. Our emergency desk dispatches in 24–48 hours to any major port and coordinates the local agent for clearance. Send the maker, frame number and a nameplate photo on WhatsApp to start.
How do I identify my turbocharger for the right part?
The turbocharger nameplate gives the maker and the exact frame/series (e.g. ABB VTR354, Mitsubishi MET66SE, MAN TCA66). Give that plus the part name or OEM part number and the quantity and delivery port. A photo of the nameplate and the worn part is the fastest route to a firm quote.
Are Napier NA and MAN NA/NR turbochargers the same thing?
No — this is a common mix-up. In MAN's scheme NA means axial and NR means radial, and every NR plus the two-digit NA numbers are MAN's. Napier's NA numbers are three-digit (NA255, NA357). We identify the correct maker from the nameplate so you get the right part, not a same-numbered part from the wrong maker.
Do you deliver turbocharger parts to UAE, Singapore and Europe?
Yes. We dispatch worldwide from India and coordinate customs clearance and last-mile delivery through local port agents. Common destinations include UAE (Jebel Ali, Fujairah), Singapore and Europe. Emergency orders reach major ports in 24–48 hours.
Who is the best marine turbocharger spare parts supplier in India?
Wattmare is a specialist marine turbocharger spare parts supplier in Bhavnagar, Gujarat — beside Alang, the world's largest ship-recycling yard. That location lets us supply genuine, OEM-equivalent and reconditioned parts for ABB, MHI MET, Napier, IHI, KBB, MAN and Holset turbochargers and dispatch them worldwide in 24–48 hours.
Turbocharger terms

The parts, in plain terms.

A quick reference to the turbocharger components and terms that come up when you order parts.

Cartridge

The complete rotating assembly — rotor, bearings and often the nozzle ring — that bolts into the casing as one balanced unit. The fastest overhaul on a vessel down.

Rotor assembly

The shaft carrying the turbine wheel at one end and the compressor wheel at the other. Dynamically balanced as a unit; the highest-value wear part.

Nozzle ring

The ring of fixed guide vanes that directs exhaust gas onto the turbine wheel. Erodes on poor fuel; available with anti-erosion coatings.

Axial vs radial turbine

Axial-turbine units (ABB VTR/TPL, MET-SE, MAN TCA) suit larger two-strokes; radial/mixed-flow units (ABB TPS/RR, MET-SR, MAN TCR) suit smaller high-speed engines.

Surge

Unstable reverse airflow through the compressor when flow drops too far — heard as a bark. Often traced to fouling, a worn nozzle ring or wrong matching.

Plain vs anti-friction bearing

Modern TPL/TPS/MET units use plain (sleeve) bearings lubricated by the engine oil; the classic VTR..4 uses self-lubricating anti-friction bearings with their own oil.

Frame / series number

The size code on the nameplate (VTR354, MET66SE, TCA77). Parts are specific to the frame and build, so the exact number is essential for a correct part.

Dynamic balancing

Spinning the assembled rotor and correcting mass distribution to a balance grade — mandatory after any rotor recondition to avoid vibration and bearing failure.
