When a main engine component fails on an obsolete engine, or an OEM quotes a 12-week lead time on a part that left production two decades ago, the conventional supply chain stops being useful. This is where Alang changes the calculation. Sitting on the Gulf of Khambhat in Bhavnagar district, Gujarat, Alang is the world’s largest ship-recycling yard, and it is also one of the most concentrated sources of genuine, low-running-hour and long-discontinued marine engine spare parts anywhere on the planet. For a chief engineer staring at an off-hire situation, understanding how to source from Alang correctly is worth real money.
What is the Alang ship-recycling yard?
Alang is a stretch of intertidal beach where end-of-life merchant vessels are run aground at high tide and dismantled. Hundreds of ships arrive every year: bulk carriers, tankers, container ships, gas carriers, offshore units and passenger vessels. Many of these ships are sent for recycling not because their machinery has failed, but because hull condition, class costs, market economics or new emissions regulations have made further trading uneconomic. The engines and auxiliary machinery on board are frequently in serviceable condition, sometimes with relatively few hours since their last overhaul.
That distinction matters. A vessel arriving at Alang is effectively a complete inventory of marine engineering hardware: a main engine, two or three auxiliary engines, turbochargers, pumps, heat exchangers, separators, governors, compressors, coolers and thousands of associated spares carried in the ship’s own store. When that ship is dismantled, all of that hardware enters the local supply chain.
Why does Alang offer parts you cannot get elsewhere?
There are two procurement problems Alang solves better than almost any other source. The first is obsolescence. Engines such as older MAN B&W and Sulzer two-stroke designs, Mitsubishi UEC main engines, Pielstick and Hanshin units, and a long tail of legacy auxiliary engines are no longer fully supported with new OEM parts, or are supported only at prohibitive prices and lead times. When a ship running one of these engines is recycled, its spares and removed components become available again. For an obsolete cylinder cover, a fuel pump housing, a turbocharger rotor or a bedplate component, Alang may be the only realistic source on earth.
The second problem is time. New OEM castings and forgings carry long manufacturing lead times. A recovered component that has already been produced, run and proven can be inspected, packed and shipped in a fraction of that time. For emergency situations where a vessel is detained or losing thousands of dollars a day in off-hire, a low-hour recovered part is often the difference between sailing this week and waiting two months.
Alang-sourced parts fall into three honest categories: genuine OEM parts recovered from the vessel or its stores, OEM-equivalent parts, and reconditioned parts that have been remachined and restored to working tolerance. A reputable supplier will always tell you which of the three you are buying. You can see how this maps across our main engine spare parts and auxiliary engine spare parts ranges.
How does a reputable supplier recover and inspect parts?
Sourcing from Alang is not the same as buying from a scrap dealer. The difference between a usable spare and a liability is the inspection process applied between recovery and sale. A serious supplier follows a disciplined sequence:
- Controlled removal. Components are removed from the engine in a planned strip-down rather than torn out during cutting. This protects machined faces, threads, sealing surfaces and matched assemblies. Critical parts are tagged at removal with the donor vessel and engine reference.
- Cleaning and preservation. Parts are degreased, cleaned and protected against corrosion immediately. Ferrous surfaces are coated; precision components are wrapped and stored dry.
- Visual and crack inspection. Each item is examined for cracks, scoring, corrosion pitting, heat damage, fretting and wear. For stressed components, dye-penetrant or magnetic-particle inspection is used to detect surface defects that the eye misses.
- Dimensional measurement. Bores, journals, liners, spindles, seating faces and clearances are measured against the OEM maintenance manual limits. The part is judged against published wear limits, not against whether it “looks fine.”
- Reconditioning where required. Where a part is outside limits but recoverable, it is remachined, re-metalled, ground or built up by qualified workshops and re-measured afterward.
The output of that process is documentation. A part you cannot trace and cannot measure is a gamble; a part with a provenance record and a dimensional report is an engineering decision.
What should a buyer check before purchase?
As the buyer, you carry responsibility for what goes onto your engine. Insist on the following before committing:
- Provenance. Which vessel, which engine make and model, and ideally the running hours or last overhaul date. A credible supplier should be able to state the donor engine for a major component.
- Correct part identification. The OEM part number, drawing number and engine type must match your application. Cross-check the stamped numbers against your spare parts catalogue, not just the description.
- Dimensional report. For wear-critical and stressed parts, ask for measured dimensions against OEM limits. This is the single most important document.
- Photographs. Detailed photos of stamped numbers, machined faces, sealing surfaces and any wear areas, taken under good light, before you pay.
- Condition category. Confirm in writing whether the part is genuine recovered, OEM-equivalent or reconditioned.
- Class acceptance. For components where your classification society requires it, confirm what documentation can be provided and whether the surveyor will accept a recovered or reconditioned part for your specific application. Some safety-critical items will require class involvement; clarify this early.
For brand-specific parts, working with a supplier who already organises stock by engine make speeds verification. Our dedicated MAN B&W engine spare parts, Wartsila spare parts and Sulzer engine spare parts sections exist so that part numbers can be matched to your exact engine type rather than guessed.
What export documentation and logistics are involved?
Once a part is identified and accepted, it has to leave India and reach your vessel. Standard documentation for marine spares export typically includes a commercial invoice, packing list, and a certificate of origin, with the appropriate HS classification for marine engine parts. Where the goods are spares for a foreign-going vessel, they may move under ship-spares or ship-stores procedures. Items are crated for sea or air freight, with heavy components secured on skids and precision parts protected against shock and moisture.
Practical logistics matter as much as paperwork. Alang’s proximity to ports and to international air freight hubs in western India means parts can be dispatched quickly once inspected. Clear marking, accurate weights and dimensions, and complete documents prevent customs delays at both ends. A supplier who handles export regularly will pre-empt the documentation a destination port requires rather than discovering it at dispatch.
How does Alang enable 24-48 hour emergency delivery?
Emergency response from Alang is possible because the inventory already physically exists and is held close to the dismantling source and to freight routes. When a vessel reports a breakdown, the supplier can search held stock, confirm part numbers against your engine, send photographs and dimensions, and have an accepted part packed and tendered to a courier or air freight forwarder the same day. For genuine emergencies, components can be on a flight within 24 to 48 hours and routed to ports across the UAE, Singapore, Europe and beyond. That speed depends entirely on the part already being identified, measured and ready, which is why the inspection discipline described above is what actually makes fast delivery real rather than promised.
Sourcing from Alang rewards engineers who ask the right questions: where did this part come from, what does it measure, what category is it, and what can be documented. Get those answers and you gain access to a parts supply that the conventional OEM channel cannot match on obsolescence, price or speed.
If you have a part number, an engine type or an urgent requirement, send it to Wattmare on WhatsApp with your engine details and we will check availability, send photographs and dimensional information, and quote you for fast worldwide dispatch.
Frequently asked questions
Are spare parts from Alang ship-recycling yard genuine or fake?
Parts recovered from Alang are genuine OEM components removed from real vessels, not counterfeits. They fall into three honest categories: genuine recovered parts, OEM-equivalent parts, and reconditioned parts that have been remachined to working tolerance. A reputable supplier states clearly which category each item belongs to and provides provenance, photographs and dimensional reports so you know exactly what you are buying.
Why source obsolete marine engine parts from Alang instead of the OEM?
For older or discontinued engines such as legacy MAN B&W, Sulzer, Mitsubishi UEC, Pielstick and Hanshin units, OEMs may no longer manufacture parts or quote very long lead times at high prices. Because end-of-life vessels running these engines are recycled at Alang, their components and ship’s stores re-enter the supply chain. For a discontinued part, Alang is often the only realistic source, and an already-produced component ships far faster than a new casting.
What documents should I ask for when buying recovered marine spares?
Ask for the part’s provenance (donor vessel, engine make and model, and running hours if known), the OEM part and drawing numbers matched to your engine, a dimensional report against OEM wear limits for stressed and wear-critical items, clear photographs of stamped numbers and machined surfaces, and a written statement of whether the part is genuine recovered, OEM-equivalent or reconditioned. Confirm class acceptance where your classification society requires it.
Will my classification society accept a part sourced from Alang?
It depends on the component and your application. Many auxiliary and non-critical parts are accepted without difficulty, while certain safety-critical components may require classification society involvement or specific documentation. Clarify class requirements with your supplier and surveyor early in the process so the necessary inspection records and acceptance can be arranged before the part is fitted.
How can Wattmare deliver marine spare parts in 24 to 48 hours?
Fast delivery is possible because Wattmare holds inspected inventory close to Alang and to western India’s freight hubs. When you report an emergency, the part can be located, matched to your engine, verified with photographs and measurements, and tendered to air freight the same day, reaching ports in the UAE, Singapore, Europe and worldwide within 24 to 48 hours. This speed relies on parts being pre-inspected and ready, not promised on arrival.
