Knowledge library

Every equipment type has a written guide.

What the machine does, how it is built, how it is selected and sized, which rules apply, what typically fails, and what to check before you accept a repair.

Written for the people who work with the machinery — superintendents, service engineers, surveyors, and students learning what a ship actually contains. 523 guides, 114 categories, all free.

Can't read the plate?

Photograph it. We identify make and model.

Hold the camera straight at the nameplate. We read manufacturer, type and serial, match them against the library, and — if you want — turn it into a parts request. We deliberately never guess: an honest blank beats an invented type designation.

Would you like to know more?

One request. A person answers within 24 hours on working days.

Tell us the manufacturer, the model and what you need — a part, a service call, a second opinion. Our desk asks the right suppliers from a network of over 114,000 companies and comes back with a quote or a sourcing plan, not a search page.

Frequently asked

Three things people ask first.

Is the library really free?

Yes. Every model page, every guide and every datasheet is readable without an account. An account adds saved searches and requests, nothing is taken away.

Where does the data come from?

From manufacturer catalogues, class-society type-approval registers and our own service work. Every value carries its source; when we could not verify a value, the field stays empty rather than guessed.

My model is not listed — what now?

Send us the nameplate. We identify it by hand, add it to the library, and if you need a part or a service, the request is already on our desk.
