scope:

This International Standard defines terms relating to dimensional co-ordination in shipbuilding. The terms are arranged in groups to cover separate aspects of the subject. Reference systems feature significantly in the dimensional co-ordination of ships and components. The "reference system" is the overall geometric netword used to divide a ship's layout and to express dimensional requirements for various components and assemblies. Within this the "controlling reference system" relates only to the size and positions of elements of construction within the dimensional framework of the ship. The "component reference system" provides, in a comparable form, the dimensional description of an individual component for the purpose of its co-ordination with adjacent components.
