Frequently asked questions

Do you supply genuine OEM Wärtsilä parts?

Yes. We source both genuine OEM parts and quality aftermarket equivalents, and we state clearly which is offered on each line of the quote.

Can you supply parts for older or legacy Wärtsilä and Vasa engines?

Yes. A large share of the installed base is legacy tonnage, and we regularly source parts for older Wärtsilä, Vasa and Sulzer engines.

What do you need to prepare a quote?

The engine type/model and the part number or a clear description (a photo of the nameplate helps). The engine serial number lets us confirm the correct revision.

Do you ship worldwide?

Yes. We deliver to ports and yards worldwide under flexible Incoterms.
