Why Vessel Core for MAN parts

Competitive alternative to MAN PrimeServ.

OEM-route and verified alternative routes are reviewed side by side so buyers can choose the route that fits approval needs, documentation, lead time and budget logic.

Cost-Aware Supply Options

Verified alternative routes for MAN B&W and MaK engines are reviewed when approval requirements, lead time and budget logic make them suitable.

OEM or Alternative — Your Choice

For class-surveyed overhauls or warranty-sensitive repairs, OEM-route components can be reviewed when documentation and approval requirements justify that route. For running spares and planned maintenance, verified alternative routes can also be reviewed.

Lead Time Confirmed at RFQ Stage

Lead time, availability and freight options are confirmed at RFQ stage based on part specification, approval requirements, vessel ETA and destination port.

Technical Part Identification

Missing part numbers or incomplete spares lists are not a barrier. We identify correct MAN components from engine type designation, bore, stroke, build year, and component photographs or drawings.

Port-Aware Delivery Planning

Supply route, handover option and freight timing are reviewed against confirmed RFQ details, vessel ETA, port context, documentation needs and part availability before quotation. No fixed delivery commitment is made before availability and route are confirmed.

Time-Critical Priority Review

Time-critical MAN B&W main engine failures receive priority RFQ review. Time-critical RFQs are checked against supplier availability, freight options, vessel timing and port timing.

Frequently asked questions

MAN parts — common questions

Can Vessel Core review OEM-route and verified alternative routes for MAN B&W engines?

Yes. Vessel Core handles MAN B&W RFQs through OEM routes and verified alternative supply paths. Alternative options are reviewed case by case according to approval needs, lead time and budget logic.

What MAN engine models do you cover?

We review common MAN B&W 2-stroke main engine requests including S50MC, S60MC, S70MC, S80MC and G80ME-C context, plus L28/32, L23/30 and L16/24 4-stroke auxiliary requests. MaK medium-speed engines and selected MAN high-speed diesel requests can also be reviewed when clear engine and part evidence is provided.

How quickly can MAN spare parts be delivered?

Lead time and freight options are confirmed at RFQ stage based on part availability, vessel ETA, destination port and urgency level.

Can Vessel Core supply MAN parts if I only have the engine model plate details?

Yes. If exact part numbers are not available, our technical supply team can identify the correct components from the engine model, bore size, build year, and description. Photographs of the installed part or model plate are also accepted as reference.
