Ship Letters

The concept of ship letter(s) is relevant for names of model objects in the hull data banks (thus, they are normally not used for drawings and other non-model types of objects). The purpose of the ship letters is:

1. The name of an object should immediately indicate to which project an object with a given name belongs. This makes it possible to store model objects from different projects (for example, sister ships) in the same data-banks even if they otherwise have the same structure of the naming (in most cases separate data-banks are used).

2. Further, the existence of the ship letters indicates that this is a AVEVA Marine name and not a part-name.

The ship letters (sometimes one but normally two) are registered in the Structure Reference object and should be added in the beginning of names even if the names are given directly by the user, that means, the ship letters are never added automatically to a name by AVEVA Marine.

However, it should be pointed out that the use of ship letters in names is optional and thus a matter of convenience. The Hull application will do perfectly well without them.

Note: In all examples of names in this document the ship letters are supposed to have been defined as AA. The ship letters of the current project should replace AA when the name rules below are applied for a customer project.
