Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 227: Application protocol: Plant spatial configuration. This part of ISO 10303 (STEP) defines the information structures and exchange requirements for representing the spatial configuration of plant and ship systems (with emphasis on piping systems), including component shapes, connections, materials and spatial arrangements used during design, fabrication and installation processes.

Abstract

ISO 10303-227:2005 (AP227) provides an EXPRESS-based application protocol for exchanging plant spatial configuration data. It covers the semantics and data structures needed to represent piping, HVAC, cableway and related mechanical systems so that geometry, topology, connectivity, fabrication and inspection information can be communicated between tools, suppliers and contractors. The AP supports planning, design, fabrication, installation and inspection workflows in process plants, shipbuilding and similar industries.

Scope

Specifies an application protocol for the exchange of spatial configuration information for industrial facilities (for example process plants and ships). The scope includes the representation of piping systems (shape, connections, materials, fabrication and inspection information), HVAC, cableways and other plant distribution and mechanical systems, and the spatial arrangement characteristics of related plant items required for design, fabrication and installation. The AP is intended for use where detailed 3D spatial and connectivity information must be exchanged or archived between engineering and production systems.

Key topics and requirements

• EXPRESS schema definitions for plant spatial configuration (entities for piping, HVAC, cableway and mechanical components).
• Geometric and topological representations of component shapes and spatial arrangement.
• Connectivity and network topology (how components connect and form systems).
• Fabrication, inspection and assembly-related data required for piping and plant components.
• Materials, fittings, connectors and standard component descriptions to support procurement and fabrication.
• Conformance and exchange requirements to enable interoperable file exchange and data-sharing between CAD/PDM/engineering systems.
• Mappings and interplay with other STEP application protocols and resources where functional or schematic data is required.

Typical use and users

Applied by engineering and design offices, shipyards, process-plant designers, EPC contractors, fabrication shops, CAD/PDM/PLM vendors, integrators and data archivists. Typical uses include neutral exchange of 3D plant models, coordination between disciplines (piping vs. structural vs. HVAC), preparation of fabrication/inspection packages, long‑term archiving of plant spatial data, and integration of specialist tools in shipbuilding and process industries.

Related standards

Part of the ISO 10303 (STEP) family; related parts and application protocols frequently used with AP227 include the core description and implementation parts (e.g., ISO 10303-1, -11, -21), and other APs that address complementary data such as AP221 (process plant functional/schematic data), AP228 (building services HVAC), AP218 (ship structures) and various industry-specific APs used in shipbuilding and process industries. AP227 is commonly referenced alongside other STEP APs when combining spatial, functional and manufacturing data.

FAQ

Q: What is this standard?

A: ISO 10303-227:2005 (AP227) is an application protocol in the ISO 10303 (STEP) family that defines data structures and exchange requirements for plant spatial configuration, primarily for piping, HVAC, cableway and related systems.

Q: What does it cover?

A: It covers the EXPRESS data models and exchange rules needed to represent component geometry and shape, spatial arrangement, connectivity and relevant fabrication/inspection information for plant and ship systems so that these can be exchanged between engineering and production software.

Q: Who typically uses it?

A: Engineers, plant designers, shipbuilders, EPC contractors, CAD/PLM vendors, integrators and fabrication/inspection teams who need interoperable 3D spatial and connectivity data exchange for piping, HVAC and related systems.

Q: Is it current or superseded?

A: Edition 2 (2005) is the published version and remains the active/confirmed international standard; it was corrected by a Technical Corrigendum in 2008 and has undergone ISO periodic review/confirmation (most recent confirmations recorded by ISO). Users should check the issuing national body or ISO for any newer revisions or amendments before procurement.

Q: Is it part of a series?

A: Yes — AP227 is one part of the ISO 10303 (STEP) series. The STEP family includes description methods, integrated resources, application protocols (APs), implementation methods and conformance/validation parts; AP227 interoperates with other APs and the core STEP parts (for example parts 1, 11 and 21).

Q: What are the key keywords?

A: Plant spatial configuration, piping, HVAC, cableway, STEP, AP227, EXPRESS, product data exchange, plant modeling, shipbuilding, fabrication, inspection.
