AP 227, Plant Spatial Configuration


The scope of Application Protocol (AP) 227 is for the exchange of 3D plant design information. AP 227 places emphasis on piping and HVAC design and includes the physical and functional characteristics of the plant items and references to specifications and stream design cases. It was developed by PlantSTEP, Inc. with active participation by owners, engineers and constructors, information technology vendors, and the National Institute of Standards and Technology (NIST).

The International Organization for Standardization (ISO) approved AP 227, Edition 1 as the International Standard, ISO 10303-227:2001.  An example of the piping design capability illustration.

PlantSTEP demonstrated the use of implementations of AP 227 at the international conferences during the development of AP 227.  The first commercial implementation of AP 227 was released in 1999.  Merck, NASA and the U.S. Navy have adopted AP 227 for exchanging plant and piping information.

NIST is working with the U.S. Navy, MARITECH, and ECOM to extend the capabilities of AP 227.  Edition 2 of AP 227 supports:
        -    pipe shop fabrication, inspection, and installation
        -    HVAC system design and installation
        -    piping and HVAC flow analysis
        -    piping stress and flexibility analysis
        -    cableway spatial layout and installation
        -    ship piping, HVAC and cableway system design and installation.

ISO approved AP 227, Edition 2 for ballot on a Draft International Standard (DIS).   The ISO ballot in the AP 227 Edition 2 DIS will end in June 2003.  During the ISO ballot, NIST is working with industry on test cases and software implementation of the AP 227 Edition 2.
