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.

• product definition data pertaining to the ship global coordinate system, local coordinate systems and spacing grids, which are used for defining the geometry of the ship structure;
• product definition data pertaining to the geometrical representation of the ship structure parts and assemblies;
• product definition data pertaining to the hull plating and the stiffener profiles, and the definition of structural features, which comprise the ship structure parts and assemblies, including functional descriptions.

EXAMPLE Edge, corner and interior cut-outs are examples of structural features

• product definition data pertaining to the design of the welded connections and joints of ship structure parts and assemblies, including edge preparations and weld type and size;
• product definition data pertaining to the specification of transverse cross-sections through the ship structure for the purpose of approval of strength;
• product definition data pertaining to ship design loads, including shear forces and bending moments acting on the ship structure, for the purpose of determining the longitudinal strength of the ship;
• product definition data pertaining to the weights and centres of gravity of the ship structure parts and assemblies;
• product definition data pertaining to the materials of ship structure, required to manufacture the ship or a part of it;
• product definition data pertaining to the configuration management of the ship structure, including approval, versioning and change administration;
• product definition data pertaining to external references, technical documentation and other supporting concepts which are necessary and pertinent to the design and manufacture of the ship structure parts and assemblies.

The following are outside the scope of ISO 10303-218:2004:

• product definition data pertaining to the ship structure at the operation and de-commissioning phases of the ship life cycle;
• business data for the management of a ship development project, such as budgets, schedules and resource requirements;
• product definition data pertaining to the direct calculation of ship structure in the design stage;
• product definition data pertaining to the coating of structural parts as well as the production tolerances;
• product definition data pertaining to the ship subdivision;
• product definition data pertaining to the ship distribution systems;

EXAMPLE The electrical, piping and HVAC systems

• product definition data pertaining to the ship machinery and propulsion systems;
• product definition data pertaining to the ship outfit and furnishing;

EXAMPLE Ladders, some foundations, pre-assembled hull outfit items, doors, and the like.

• product definition data pertaining to ship hull structure parts which are manufactured by forging or casting.

EXAMPLE Stern frames, rudder horns and propeller shaft brackets.
