Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 218: Application protocol: Ship structures (ISO 10303-218:2004). Defines the STEP application protocol for exchanging product definition data, configuration (revision/change history) and approval-status information specifically for ship structural systems (hull, superstructure and internal structure) across design and manufacturing phases.

Abstract

ISO 10303-218:2004 specifies the integrated resources and information requirements needed to exchange product definition data for ship structures, including geometry, structural parts and assemblies, hull plating and stiffeners, welded connections, transverse cross-sections, design loads, weights and centres of gravity, materials, configuration management (versioning, approval and change history) and references to supporting documentation. The standard supports shipbuilding activities in pre-design, main design and manufacturing stages and includes activity/process models (Annex F) and detailed harmonization discussion (Annex L).

Scope

Covers product definition data for ship structures (commercial and naval) including global and local coordinate systems, spacing grids, geometric representation of parts and assemblies, hull plating and stiffener profiles, structural features (cut-outs, edges), welded connections and joint details, transverse sections for strength approval, ship design loads, material specifications, weights and centres of gravity, and configuration management (revision tracking, approvals). Excludes operational/decommissioning-phase structural data, project business data (budgets, schedules), direct structural calculation models, coating/tolerances, ship subdivision, distribution systems (electrical, piping, HVAC), machinery/propulsion systems and outfitting items not part of the primary structural definition.

Key topics and requirements

• Standardized EXPRESS-based data models for ship-structure geometry and assemblies.
• Definitions for hull plating, stiffeners and structural feature representation.
• Support for welded connections, edge preparations and weld specification data.
• Representation of transverse cross-sections and design loads for strength approval.
• Material, weight and centre-of-gravity data for structural components.
• Configuration management: revision/version history, change administration and approval status (company and classification society).
• Integration with STEP resources and harmonization with other ISO 10303 parts; application activity models and annex guidance for implementation.

Typical use and users

Used by shipbuilders, naval architects, ship design offices, shipyards, classification societies, CAD/CAM/PDM software vendors and integrators to exchange ship structural product data between engineering, design and manufacturing systems, to support approvals and configuration management, and to enable long-term archival and interoperability of structural design information.

Related standards

Part of the ISO 10303 (STEP) family. Closely related to core and implementation parts such as ISO 10303-1 (overview and fundamental principles), ISO 10303-11 (EXPRESS language), ISO 10303-21 (STEP-file), and other application protocols and APs used for product model exchange (for example AP203/AP214/AP242 and STEP resource modules). Implementers often use the STEP Module and Resource Library (SMRL) and related resource parts when mapping or extending AP218 data.

FAQ

Q: What is this standard?

A: ISO 10303-218:2004 (AP218) is a STEP application protocol that defines a standardized data model and exchange requirements for ship structural product definition data and associated configuration/approval information.

Q: What does it cover?

A: It covers geometric and semantic product definition data for ship structures (hull, superstructure, internal structure), including structural part and assembly definitions, plating and stiffeners, welds, cross-sections, loads, materials, weights/centres of gravity and configuration/approval metadata for design and manufacturing phases.

Q: Who typically uses it?

A: Shipyards, naval architects, ship designers, classification societies, CAD/CAM/PDM vendors and systems integrators that need to exchange detailed ship structural data and manage revisions and approvals across engineering and manufacturing workflows.

Q: Is it current or superseded?

A: The 2004 edition (Edition 1) remains the published version. The standard has been periodically reviewed and, as published by ISO, was confirmed and remains current following ISO review cycles. Users should check ISO or their national standards body for the latest confirmation or revision activity before assuming a newer replacement exists.

Q: Is it part of a series?

A: Yes — it is Part 218 of the ISO 10303 series (commonly known as STEP), a large collection of parts covering data representation, schema languages (EXPRESS), file formats (STEP-file), resource modules and many application protocols for different industries and product types.

Q: What are the key keywords?

A: STEP, AP218, ship structures, product data exchange, configuration management, hull, stiffeners, welds, classification society, CAD/PDM interoperability.
