Ship drawings are important for the conveyance of information between all levels and members of a project. Naval architecture is no different in this regard. Accurate drawings are particularly important to vessels which are classified and/or registered with a flag state, as copies are required to be submitted to the appropriate society for approval before building. These become legal documents once accepted.
Most drawings supplied as part of a design package will see multiple revisions, as the vessel follows through the stages of design. The complete set of drawings for a vessel will generally come from multiple sources, including client, suppliers, the design firm, the shipyard, and potentially even another design firm for production drawings.
In addition, a vessel project will also create a number of systems drawings.
