Plant item is a basic unit used for the representation of plant’s logical configuration and geometry. Geometric objects, called primitives, are combined by using Boolean operations to create a complex 3D shape. ISO 15926 is an international standard for the integration and sharing of plant lifecycle information. Contrary to other types of design data, few studies on ISO 15926-based 3D shape representation have been reported. As part of the research for ISO 15926-based 3D shape representation, we suggest how to link a plant item and its geometric representation using ISO 15926 templates and their representation in OWL.

The Asset Administration Shell (AAS) is a standard tool that can support the digital representation of a process plant. We present a method to use AAS coupled with ISO 15926 to facilitate the exchange of maintenance data in process plants. To accomplish this, the operation and maintenance (O&M) system framework employed in process plants is defined. Information requirements are derived based on this framework, and a maintenance data structure is designed. Along with this, reference data are applied to identify the types of equipment and properties of each equipment type using ISO 15926. According to the pre-designed data structure, a neutral format based on AAS is developed to exchange maintenance data among software systems in O&M. The neutral format is verified through a test case of exchanging maintenance data (equipment condition and health status data) in terms of applicability to O&M systems in the fiel...

The data generated by each stakeholder involved in the plant life-cycle are closely related to each other. Therefore, it is important to link and integrate the various data created by each stakeholder. In this study, a method of integrating plant life-cycle data, including the equipment maintenance history, was proposed based on the International Organization for Standardization 15926 standard. To this end, a data model for integrating plant life-cycle data, including maintenance, was developed using the International Organization for Standardization 15926 standard. The proposed method was validated by developing a prototype system and performing experiments converting and visualizing life-cycle data, including maintenance history in the International Organization for Standardization 15926 format, using sample data from a refinery plant.

However, it is not easy to implement Part 2 Data Model and Part 4 Initial Reference Data Library because of their complexity in terms of data structure and a shortage of related development toolkits. In order to overcome this problem, ISO 15926 Part 7 is under development. This part of the standard specifies implementation methods for sharing and exchange of process plant data across its lifecycle by utilizing OWL and Web Services. For the application of ISO 15926 Part 7, we first discuss how to represent technical specifications of process plant equipment by utilizing the user defined Reference Data Library and Object Information Model with an example of reactor coolant pumps located in the reactor coolant system of an APR 1400 nuclear power plant. An implementation plan of ISO 15926 Part 7 is also addressed after analyzing enabling technologies and surveying related tools.

Parts of this lifecycle information are stored in a plethora of computer systems, often scattered around the world and in many native formats and languages. These parts can create a complete, holistic set of lifecycle data only when they are integrated together. At present, no software is available that can integrate these parts into one coherent, distributed, and up-to-date set. The ISO 15926 standard has been developed, and in part is still under development, to overcome this problem. In this paper, the authors discuss a prototype of an ISO 15926-based data repository called a façade, and its Web services are implemented for storing the equipment data of a nuclear power plant and servicing the data to interested organizations. This prototype is for a proof-of-concept study regarding the ISO 15926 parts that are currently under development and that are expected to provide implementation methods for the integration of distributed plant systems.
