ISO 10303-218:2004 specifies the use of the integrated resources necessary for the scope and information requirements for the exchange of product definition data and its configuration and approval status information for ship structural systems. Configuration in this context pertains to data specific to revision tracking and change history of selected ship structural entities within the product model. Approval pertains to the company internal approval and the classification society approval. ISO 10303-218:2004 supports the shipbuilding activities and applications associated with the design phase and the manufacturing phase. NOTE 1 The application activity model in Annex F provides a graphical representation of the processes and information flows that are the basis for the definition of the scope of ISO 10303-218:2004. NOTE 2 The detailed technical discussion in Annex L provides details that define the basis for the definition of the scope of ISO 10303-218:2004 and details that define the basis of harmonization with other parts of ISO 10303 for product exchange of data for ships. The following are within the scope of ISO 10303-218:2004:

• product definition data pertaining to the ship structure which includes hull structure, superstructure and all other internal structures of commercial and naval ships;
• product definition data pertaining to the ship structure;
• product definition data pertaining to the pre-design phase of the ship structure;
• product definition data pertaining to the main design phase of the ship structure;
• product definition data pertaining to the manufacturing phase of the ship structure;
• product definition data pertaining to the product structuring of ships, including the structuring by system and by assemblies within the ship;
• product definition data identifying the ship general characteristics which are relevant to the design of the ship structure.

NOTE The general characteristics include ship main dimensions, designations and principle characteristics, as well as the rules, regulations and standards applicable to the ship. They also include lightships weight distribution and free-board characteristics for the purpose of design and design approvals.
