LNG Carrier at sea — marine spare parts supplier from Alang, India | Wattmare9 systems · 60+ brands · 24–48h dispatch

LNG carrier spare parts are the components that keep a liquefied-natural-gas tanker running — cargo compressors, boil-off and reliquefaction plant, dual-fuel engines (MAN ME-GI, WinGD X-DF, Wartsila DF gensets), cryogenic cargo pumps, turbochargers and auxiliaries. Wattmare supplies all of them, genuine, OEM-equivalent or reconditioned, worldwide in 24–48 hours.

  • Containment: Moss-type spherical & membrane (GTT Mark III, NO96) tank systems
  • Main engines: MAN B&W ME-GI, WinGD X-DF dual-fuel, DFDE diesel-electric & legacy steam turbine
  • Cargo plant: HD/LD cargo compressors, boil-off gas handling, reliquefaction & re-gasification skids
  • Gensets: Wartsila DF, MAN & Caterpillar dual-fuel sets feeding HV switchboards
  • Size classes: small-scale, conventional 138,000–180,000 m³, Q-Flex & Q-Max
  • Cargo temperature: LNG carried at −163°C in cryogenic deepwell & spray pumps

An LNG carrier is one of the most machinery-dense vessels afloat. Beyond the dual-fuel propulsion train, the cargo plant alone — high-duty and low-duty compressors, boil-off gas handling, reliquefaction or re-gasification skids, and cargo pumps running at −163°C — carries spares lead times that can sideline a ship for weeks if a single component is unobtainable. Wattmare exists to close that gap. We hold and source parts across the entire vessel, whether your fleet runs Moss-type spherical tanks or membrane containment, and whether the prime mover is a modern MAN ME-GI, a WinGD X-DF, a DFDE diesel-electric arrangement or a legacy steam turbine.

Operating from Bhavnagar, on the doorstep of Alang — the world’s largest ship-recycling yard — gives us a sourcing advantage no pure trader can match. We recover, inspect and recondition genuine OEM components from decommissioned tonnage, and pair that stock with new genuine and OEM-equivalent supply. Every part is traceable, condition-graded and backed by our 24–48 hour emergency dispatch to all major LNG terminals and bunkering hubs. One enquiry covers the whole ship — propulsion, power generation, cargo handling, purification and auxiliaries.

WHERE FAILURES HAPPEN AT SEA

A breakdown doesn’t wait for port.

The moments a lng carrier is most likely to need a part — and the spares we keep ready for each.

Cargo compressor valve & bearing failure — lng carrier spare parts | Wattmare

Cargo compressor valve & bearing failure

HD and LD cargo compressors run continuously during loading, discharge and BOG management. Worn suction/discharge valves, bearings and seals cut capacity and trip the plant. We supply matched valve sets, bearings and gaskets to restore cargo-handling availability quickly.

Dual-fuel gas-admission valve faults — lng carrier spare parts | Wattmare

Dual-fuel gas-admission valve faults

On ME-GI and X-DF engines, sticking or eroded gas-admission and pilot-injection valves cause knocking, gas trips and forced diesel-mode operation. We stock genuine and OEM-equivalent valves and control components to keep the engine in gas mode and emissions compliant.

Cryogenic cargo pump degradation — lng carrier spare parts | Wattmare

Cryogenic cargo pump degradation

Deepwell and submerged spray pumps operating at −163°C suffer bearing, seal and impeller wear that reduces discharge rate and risks downtime at the terminal. We source reconditioned and replacement pump internals to keep loading and discharge on schedule.

Genset & switchboard reliability issues — lng carrier spare parts | Wattmare

Genset & switchboard reliability issues

DFDE carriers lose propulsion if dual-fuel gensets or HV switchboards fail. Cylinder-unit wear, governor faults and breaker problems are common — we carry genset spares and electrical components to protect the entire diesel-electric plant.

THE COMPLETE GUIDE

LNG Carrier spare parts, explained.

One supplier for the entire LNG carrier

LNG carriers combine cryogenic cargo systems with complex dual-fuel propulsion, and chasing each part through a different vendor wastes the hours that matter most when a ship is alongside. Wattmare consolidates the whole vessel into a single enquiry — main engine, turbocharger and auxiliary engine spares alongside cargo-plant and electrical components.

That single point of contact means one quotation, one consolidated shipment and one set of documents — faster clearance at the terminal and less administration for your superintendents and purchasing teams.

One supplier for the entire LNG carrier — Wattmare

Genuine, OEM-equivalent & reconditioned options

Not every LNG carrier requirement justifies a full-price genuine part, and not every part is available new on a short timeline. We offer all three grades — genuine OEM, OEM-equivalent and quality-graded reconditioned — so you can balance budget, criticality and lead time against class requirements.

Reconditioned components recovered at Alang are stripped, measured, NDT-checked where relevant and graded before dispatch, giving you genuine OEM hardware at a fraction of new-build cost for non-critical and back-up spares.

Genuine, OEM-equivalent & reconditioned options — Wattmare

Cargo & cryogenic systems covered

Beyond the engine room, we support the machinery unique to gas carriers — HD/LD cargo compressors, boil-off and reliquefaction plant, cryogenic cargo and spray pumps, inert-gas and nitrogen systems, and the refrigeration compressors serving provision and cooling duties.

Heat exchange and purification on an LNG carrier protect both engines and cargo-handling motors, so we also supply heat exchanger, oil separator and fresh-water generator spares as part of the same scope.

Cargo & cryogenic systems covered — Wattmare

Built for emergency LNG operations

LNG terminal slots are tightly scheduled and demurrage is expensive, so an unobtainable part can cost far more than the part itself. Our Bhavnagar base, deep Alang sourcing network and 24–48 hour worldwide dispatch are designed for exactly these situations, including starting and control air and governor emergencies.

Send us the maker plate, part number and photographs and we will confirm availability, grade and price quickly — then route the part to your terminal or agent by the fastest viable air or courier service.

FAQ

Questions, answered.

lng carrier spare parts laid out | Wattmare
Do you supply spare parts for both Moss-type and membrane LNG carriers?

Yes. We supply engine-room, cargo-plant and auxiliary spares for both Moss-type spherical-tank carriers and membrane containment vessels (GTT Mark III and NO96). The containment system mainly affects cargo-handling layout; the propulsion, power-generation and auxiliary machinery we cover is common to both.

Can you provide parts for MAN ME-GI and WinGD X-DF dual-fuel engines?

Yes. We supply gas-admission and gas-injection valves, pilot-fuel injectors, exhaust valves, liners, piston crowns, bearings and electronic control components for MAN B&W ME-GI and WinGD X-DF engines, in genuine, OEM-equivalent and reconditioned grades.

Do you stock spares for DFDE diesel-electric LNG carriers?

Yes. For DFDE vessels we supply spares for Wartsila DF, MAN and Caterpillar dual-fuel gensets, plus high-voltage switchboard, breaker and propulsion-motor electrical components that make up the diesel-electric propulsion plant.

What about older steam-turbine LNG carriers?

We support legacy steam-propelled LNG tonnage with gland packing, bearings, governor and control valves, condenser tubes and boiler-feed components. Many of these parts are sourced reconditioned from decommissioned vessels at Alang.

Can you supply cargo compressor and reliquefaction plant spares?

Yes. We supply HD and LD cargo compressor valves, bearings and seals, boil-off gas handling components and reliquefaction/re-gasification skid spares, helping keep cargo handling and BOG management fully available.

Do you handle cryogenic cargo pump spares?

We source replacement and reconditioned internals — bearings, seals, impellers and shafts — for deepwell and submerged cargo and spray pumps that operate at −163°C. Send us the pump maker and model and we will advise on availability.

How fast can you deliver an emergency LNG carrier part?

Our standard emergency target is 24–48 hours to most major LNG terminals and bunkering hubs worldwide, dispatched from Bhavnagar by the fastest viable air or courier route once availability and payment are confirmed.

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

Genuine parts are supplied by the original equipment manufacturer; OEM-equivalent parts are made to the same specification by quality manufacturers; reconditioned parts are genuine components recovered, inspected, NDT-checked where relevant and condition-graded. We help you choose based on criticality, class requirements, budget and lead time.

Are reconditioned parts from Alang reliable for critical systems?

Reconditioned components are graded and best suited to back-up and non-critical applications, or where new supply lead times are prohibitive. For class-critical items we recommend genuine or OEM-equivalent. Every reconditioned part is inspected and graded so you know exactly what you are receiving.

Which size classes of LNG carrier do you cover?

All of them — small-scale and bunkering carriers, conventional 138,000–180,000 m³ ships, Q-Flex and Q-Max vessels, and FSRU/regas-fitted units. The propulsion makers differ, but we cover the full range of engines and auxiliaries used across the fleet.

Can I order parts for the whole vessel in one enquiry?

Yes, and we encourage it. A single enquiry can cover main engine, turbocharger, gensets, cargo plant, purification, air and refrigeration systems — consolidated into one quotation, one shipment and one set of documents.

What information do you need to quote an LNG carrier part?

The maker and model of the equipment, the part number or drawing reference, the quantity required, and clear photographs of the component and its maker plate. The more detail you provide, the faster and more accurately we can confirm availability and grade.

Do you ship to LNG terminals and bunkering ports worldwide?

Yes. We regularly dispatch to Ras Laffan, Sabine Pass, Singapore, Fujairah, Gladstone, Zeebrugge, Rotterdam and other major terminals, working with your port agent or technical superintendent to ensure smooth delivery and customs clearance.

Do you supply turbocharger spares for LNG carrier engines?

Yes. We supply rotors, bearings, nozzle rings, cartridges and overhaul kits for ABB TPL and A-series, MHI MET and Napier turbochargers fitted to dual-fuel main engines and gensets, in genuine, OEM-equivalent and reconditioned options.
