Plant, civil engineering and construction equipment data of overseas construction are obtained and then analyzed, classified and integrated by experts. With those refined data set, we built classification system and defined property information with reference to international standard (ISO 15926, IRDL). If class in ISO 15926 is predefined for equipment of interest, we used the class as is. If not, we created and defined new classes on the basis of ISO 15926 classes. If there is similar class for equipment of interest, extension or inheritance methods were used. As a result, classification system of five levels and 637 classes were built and construction equipment information were expressed in open structure of XML such as tree structure of classification system and detailed information with number equipments for each specific equipment. We also developed the electronic catalog system which is basically equipment information management system providing various product search functions.

ISO 10303-AP241 is an Application Protocol of ISO 10303, which specifies the representation of AEC facility's life cycle information. The Working Draft of AP241 was submitted to the TC184/SC4 of ISO in July, 2007 by Korean team of ISO TC184/SC4/WG3. This paper introduces the currently developed draft Ap241 core model, and describes the life cycle support modules which are required to represent the life cycle information of AEC facilities. The draft core model is developed as a generic data model which is useful as a basis for implementation in a data warehouse. This core model could be used in combination with reference data such as PLCS RDL, Gellish table and RDL of ISO 15926. These concepts already exists in ISO 10303-AP221, AP239 and ISO 15926. In order to support maintenance and feedback of operational information concerning the AEC facilities, the AP241 team re-used many modules from AP239, and developed various STEP Application Modules which are adapted from the ISO 15926.

This paper addresses the issues related to the development of product model and applications fer nuclear power plants based on STEP and PLIB standards. The ISO standards which can be applied are; STEP(Standard for the Exchange of Product Model Data) AP(application protocol) 221/231, AP 230/225, AP 227, ISO 13584 PLIB, ISO 15926 RDL. The data models of the AP's and ISO 15926 RDL are reviewed and an application system is proposed to exchange and share the design data of the nuclear power plant.

In this paper chemical process plant information is addressed to be standardized. The chemical process plant information has complexities in the context of its various types such as functions, shapes, connectivity etc. as well as its usages such as design, construction, operation, maintenance and so on. It was well known that the standard should be made by its users themselves to be used widely. The chemical process industry oriented ISO 15926 RDL (Systems and integration of life-cycle data for oil and gas production facilities : Reference Data Library) can provide the methodology for exchanging and sharing of plant equipment information, which will be developed through integrating existing standards such as ISO 10303 AP221, AP231, AP227. The PCA (Posc Caesar Association) which is located in Oslo, Norway, has the initiative in developing ISO 15926. Korea is a member of PCA and takes part in proposing and reviewing the new standard. The trends and prospects for the standard of chemical process plant information are addressed.

Representation of product data for exchanging and sharing a plant information was established the International Standard by ISO 10303 (STEP) and ISO 15926, but is not used widely in industrial circles by massiveness of standard and complexity of plant itself Specially, they are embodied to STEP data file(ISO 10303 Parts 21), but STEP file is uncomfortable that a person recognizes, and needs specification creation tool. In this paper, we made the integration schema for control valve through related standards, Also, we suggest the practical use framework for electronic commerce to utilize the XML schema that can represents integrate schema of control valve to use XML that is becoming the latest issue.

원자력발전 산업은 국내 최대의 전력공급원으로서 '09년 현재 20기의 원전이 가동 중에 있고 8기의 원전이 건설 중이다. 또한 수출주도형 독자노형 개발을 목적으로 한 원전 설계 개발 사업도 진행되고 있다. 국가 기반산업이기도 한 원자력 산업에는 다양한 정보관리시스템들이 운영되고 있으며 지속적인 개선이 이루어지고 있다. 원자력발전소는 60년에 이르는 긴 수명주기를 가지고 있기 때문에 설계 단계에서부터 생산되는 정보를 관리할 수 있는 체계적인 방법이 필요하며, 산업 특성상 다양한 참여기관들이 상호 협업을 진행할 수 있는 통합 창구 역할의 시스템이 요구되고 있다. 본 연구에서는 원자력발전소의 정보관리시스템 개발을 위해 신규원전 사업자에게 요구되는 EPRI URD 요건 및 실제 원전 설계개발 사업에서의 시스템 요구사항 등을 분석하여, 원자력발전소의 원전 정보관리시스템 개발요건을 도출하였으며 ISO 10303 국제표준 기술을 활용한 일부 시스템 프로토타입 구현을 통한 예비 타당성 평가를 수행하였다. 본 연구를 통해 국내 원전 산업에 국제표준 도입 가능성은 확인하였으나, 국제표준 개발이 아직 진행 중인 점을 고려할 때 실제 원전 적용을 위해서는 향후 추가 연구가 필요하다.

본 논문에서는 제품 정보를 교환 및 공유하기 위한 국제 표준인 ISO 15926에 근거한 해양 플랜트 기자재의 제품 정보의 온톨로지 모델링을 소개한다. 모델링 방법은 코어 데이터 모델과, 참조 데이터 라이브러리, 템플릿과 객체 정보 모델을 이용한다. 코어 데이터 모델은 보편적인 개념을 정의하고, 참조데이터 라이브러리는 코어 데이터 모델을 확장한 공통 용어 사전이다. 의미를 표현하는 가장 작은 조각으로 템플릿을 사용하고, 객체 정보 모델을 통하여 객체들 사이의 관계를 정의한다. 모델링은 OWL을 이용하여 제품 데이터의 온톨로지를 생성하여 이기종 소프트웨어 간의 제품 정보를 교환하고 공유하도록 한다.

Plant life cycle consists of design, construction, certification, operation, and maintenance phases, and various and enormous plant life cycle data is involved in each phase. Plant life cycle data should be linked with each other based on its proper relationships, so that plant operators can access necessary plant data during their regular operations and maintenance works. Currently, the relationships of plant life cycle data may not be defined explicitly, or they are scattered over several plant information systems. This paper proposes high level design of a plant life cycle data management system based on pre-defined plant life cycle database design. ISO-15926 standard is adapted for the database design. User-interface designs of the plant life cycle data management system are explained based on analysis of plant owners' requirements. A conceptual design of the database is also described with the entity-relationship diagram.

During the lifecycle of a nuclear power plant many organizations are involved in KOREA. Korea Plant Engineering Co. (KOPEC) participates in the design stage, Korea Hydraulic and Nuclear Power (KHNP) operates and manages all nuclear power plants in KOREA, Dusan Heavy Industries manufactures the main equipment, and a construction company constructs the plant. Even though each organization has a digital data management system inside and obtains a certain level of automation, data sharing among organizations is poor. KHNP gets drawing and technical specifications from KOPEC in the form of paper. It results in manual re-work of definition and there are potential errors in the process. A data warehouse based on a neutral model has been constructed in order to make an information bridge between design and O&M phases. GPM(generic product model), a data model from Hitachi, Japan is addressed and extended in this study. GPM has a similar architecture with ISO 15926 "life cycle data for process plant". The extension is oriented to nuclear power plants. This paper introduces some of implementation results: 1) 2D piping and instrument diagram (P&ID) and 3D CAD model exchanges and their visualization; 2) Interface between GPM-based data warehouse and KHNP ERP system.
