Stock items dispatch the same or next working day from Bhavnagar. Emergency orders ship in 24–48 hours to any major port. Sourced items depend on the yard — we confirm a real date before you commit.
Are your UEC33LSE parts genuine or reconditioned?
Both. We supply genuine and OEM-equivalent new parts, and Alang-reconditioned parts measured against the maker's limits before dispatch. We tell you which you are buying — we do not sell reconditioned as new.
Who manufactures the UEC33LSE today?
The UE engine programme transferred from Mitsubishi Heavy Industries (MHI-MME) to Japan Engine Corporation (J-ENG), whose current lineup lists the UEC33LSE-C2. Spares for earlier UEC33LSE and UEC33LSII engines remain fully available — the LSE and LSII share the same 330 mm UEC33 frame.
Which vessels typically run the UEC33LSE?
Bulk carriers, chemical tankers, cement carriers and asphalt carriers under roughly 30,000 DWT — the 330 mm bore and long 1,550 mm stroke (stroke/bore 4.70) give direct low-rpm propeller drive at 167 rpm with class-leading fuel consumption.
