In the plant industry, the share of equipment accounts for 45 ~ 75%, which is very high. It is a traditional plant centered on processes and reactions like petroleum and chemical plants. Renewable energy generation plants such as wind power generation and solar power generation are equipment-centric plants. Equipment-centric plants are very important not only in the EPC phase but also in the operation and management phase. The procurement of equipment for plant operation and management can be divided into make and buy. Make is a method of producing equipment itself, and buy is a method of procuring equipment from the outside. The procurement method of the equipment directly affects the plant operation and management cost. In this study, the decision making of equipment procurement method for plant operation and management is defined as 4 phase. Each phase is selection of procurement decision-making objects, technology strategy perspective, finance perspective, and production perspective. In detail, we defined selection process of procurement decision-making objects and technology strategy perspective process. We will contribute to the enhancement of the competitiveness of the plant operation and management area by carrying out researches on the process and application examples of financial and production perspectives in the future.

<P><B>Abstract</B></P> <P>In a nuclear power plant, classification is a key tool to manage equipment and materials. There could be different classifications corresponding to the different lifecycle phases and the challenge is to achieve and maintain interoperability, continuity, traceability between them. Therefore, it is important to define the equipment and materials classification based on standardized information models in order to effectively share and integrate lifecycle data of equipment and materials. To accomplish this, a method for standardized exchange of plant equipment and materials data based on ISO 15926 methodology in nuclear power plants is suggested. In the proposed method, we use an information model to expand the equipment and materials classification used for the operation and maintenance phase of a nuclear power plant. This is based on the ISO 15926 standard after analyzing the master data from the Shin Kori unit 1 and 2 of Korea Hydro & Nuclear Power Co., Ltd. (KHNP). Furthermore, as a data exchange tool in the proposed method, this study develops a method to exchange equipment and materials specification data by using iRINGTools.</P> <P><B>Highlights</B></P> <P> <UL> <LI> This study extends the equipment classification of a nuclear power plant based on the ISO 15926 standard. </LI> <LI> This is followed by constructing a user-defined reference data server for the extended classification. </LI> <LI> A method to exchange equipment specification data by using iRINGTools is also proposed. </LI> <LI> The reference data server and iRINGTools are used to exchange equipment specification data of the nuclear power plant. </LI> </UL> </P>

Enhancement of equipment information sharing using three-dimensional computer-aided design simplification and digital catalog techniques in the plant industry

Kwon, Soonjo,Kim, Byung Chul,Hwang, Hojin,Mun, Duhwan,Han, Soonhung SAGE Publications 2016 Concurrent Engineering Vol.24 No.3

<P>Process plants are designed and constructed by engineering, procurement, and construction companies, which order various types of equipment to be installed in them. Equipment manufacturers design and produce the ordered equipment, and deliver it to the customer. Therefore, equipment information sharing between them is an important issue for engineering collaboration in a plant project. However, they use different three-dimensional computer-aided design systems for different purposes. For this reason, additional three-dimensional computer-aided design and data merging techniques are required for equipment information sharing. This article presents a new approach to share equipment information using three-dimensional computer-aided design simplification and digital catalog techniques. In this approach, the equipment's three-dimensional computer-aided design data generated by a manufacturer are first simplified and then converted into neutral three-dimensional computer-aided design. The converted three-dimensional computer-aided design data are merged with port and specification data into a digital catalog. Equipment information in the form of this digital catalog is finally delivered to the engineering, procurement, and construction companies.</P>

During a nuclear power plant life-cycle exceeding 60 years, data interoperability problems are occurred in its life-cycle. Standard classification among over than several hundred organization in plant project for their equipment definition is important to solve data interoperability problem. In particular, ISO 15926-4 proposes Initial Reference Data Library (IRDL) to solve data interoperability problems using a common reference data dictionary. However, there are no standard equipment classification (dictionary) for nuclear power plant industry. A process plant and a nuclear power plant have common features, it can be referred to make new equipment library for nuclear power plant. Therefore, in this paper, the authors analyze current status of equipment classification in the current nuclear power plant and suggest a way of mapping to build a reference data library for the nuclear industry. The authors then propose an extended classification methodology using characteristic of property value.

이재용,김형진,이춘식,박찬국 한국가스학회 2019 한국가스학회지 Vol.23 No.2

To develop a plant safety training system using virtual reality technology, we constructed a training system for a large scale plant. Compared with safety training for small plants or unit equipment, many system configurations such as virtual plant model, in-process data processing, work instruction, etc. are required and integrated system works have been carried out. The target plant, RDS process, is a high-risk process(high-temperature, high-pressure) that takes into account the training scenarios that can be taken in the event of a leaking fire in the range and refer to the actual shutdown procedure. The proposed safety training integration system can be used in similar situations that can occur in the RDS process and can be a platform for safety training using virtual reality in a large plant. 가상현실 기술을 이용한 플랜트 안전훈련 시스템 개발을 위해서 대규모 플랜트를 대상으로 훈련 시스템을 구성하였다. 소규모 플랜트 또는 단위장치의 안전훈련에 비해서 가상 플랜트 구현, 공정 내 데이터 처리, 작업 지시 등많은 시스템 구성이 필요하며 이들에 대한 통합 시스템 작업을 진행 하였다. 대상 플랜트인 RDS 공정은 고온 고압의 위험도가 높은 공정으로 해당 범위에서 누출로 인한 화재가 발생할 경우에 조치할 수 있는 훈련 시나리오를 고려하였으며 실제 사용 중인 운전 정지 절차를 참조하였다. 제안한 안전훈련 통합 시스템은 RDS 공정에서 일어날 수있는 유사 상황에서도 이용 가능하며 대규모 플랜트에서의 가상현실을 이용한 안전훈련의 새로운 플랫폼으로 고려될 수 있다.

플랜트 설비 지지용 대안 강구조 시스템의 내진성능

곽병훈,안숙진,박지훈 한국지진공학회 2023 한국지진공학회논문집 Vol.27 No.1

In this study, alternative seismic force-resisting systems for plant structure supporting equipment were designed, and the seismic performance thereof was compared using nonlinear dynamic analysis. One alternative seismic force-resisting system was designed per the requirement for ordinary moment-resisting and concentrically braced frames but with a reduced base shear. The other seismic force-resisting system was designed by accommodating seismic details of intermediate and unique moment-resisting frames and special concentrically braced frames. Different plastic hinge models were applied to ordinary and ductile systems based on the validation using existing test results. The control model obtained by code-based flexible design and/or reduction of base shear did not satisfy the seismic performance objectives, but the alternative structural system did by strengthened panel zones and a reduced effective buckling length. The seismic force to equipment calculated from the nonlinear dynamic analysis was significantly lower than the equivalent static force of KDS 41 17 00. The comparison of design alternatives showed that the seismic performance required for a plant structure could be secured economically by using performance-based design and alternative seismic-force resisting systems adopting minimally modified seismic details.

In a process plant project, diverse stakeholders use different plant 3D CAD systems for basic and detail designs. Plant design using a plant 3D CAD system needs catalog library for equipment and materials such as pipes, fittings, and equipment. Building catalog library based on a neutral model and using it at plant 3D CAD systems increase the usability of the library and decrease time required for the construction of a catalog library for a specific project. To accomplish this, a system to support translation of a neutral catalog data to a native catalog data of a plant 3D CAD system. In this paper, three data structures are defined for the translation between neutral and native catalogs: a neutral data structure used for storing equipment and materials’ classification and their catalogs, a data structure storing mapping data between neutral and native catalog data, and a data structure for auxiliary information. After the definition of data structures, a system to support the translation is designed. Finally, a prototype system is implemented according to the design and experiments with test cases were performed to verify the feasibility of the prototype system.
