한성종,박범,Han, Seong Jong,Park, Peom 한국플랜트학회 2017 플랜트 저널 Vol.13 No.4

본 논문은 해양플랜트 입찰단계에서 시스템엔지니어링(Systems Engineering)기법을 이용하여 해양플랜트를 구성하고 있는 장비 배치를 검증(Verification)할 수 있는 검증수행모델에 대한 연구이다. 해양플랜트 상부구조물(Topside) 유지보수 장비들을 엔지니어링하기 위하여는 Topside 장비 Layout검증이 선행되어야 한다. 하지만 입찰단계에서 완성도가 높지않는 FEED(Front End Engineering Design)결과물로 인한 많은 오류가 존재함에도 불구하고 검토시간의 부족 등의 이유로 검증을 수행하지 못하는 경우가 존재한다. 따라서 본 논문에서는 다학제간 접근방식인 시스템엔지니어링 프로세스를 간략화하여 적용함으로써 제한된 시간내 효과적으로 장비배치를 검증할 수 있는 검증수행모델을 제안하였다. 모델의 구성은 기능전개모델(Functional Deployment Model)을 통하여 구축하였으며 사례연구를 통하여 본 Topside 장비 배치에 대한 검증 수행모델을 검증하였다. This paper is a study on validation model that can verify the arrangement of equipment constituting offshore plant using system engineering approach in offshore plant tender stage. In order to design offshore plant topside maintenance equipment, topside layout verification should be preceded. However, there are many errors in the bidding stage due to the FEED results that are not perfect, the verification can not be performed sufficiently due to the limitation of the bidding period and others reasons. Therefore, we propose a validation model that can effectively verify the equipment layout within a limited condition by simplifying the main process in the system engineering process, which is a multidisciplinary approach, and confirmed through the Functional Deployment Model. Also, we verified the validation model for topside equipment deployment through case studies.

본 연구는 Offshore Oil & Gas 산업에서의 장비 및 벌크자재 국제표준화 추진에 대한 접근방법에 대한 연구로 국제표준화를 위한 요구사항을 분석하고 표준화 장비의 우선순위 선정 및 1단계 표준화 결과를 설명한다. 현재 국제적으로 진행되고 있는 표준화활동은 크게 3개의 활동들로 구분할 수 있으며 첫째로 국내 대형 조선3사가 주도하여 진행하는 벌크자재 국제표준화활동, 둘째로 IOGP의 주도하에 진행되는 JIP33 장비표준화 활동 및 마지막으로 선급을 중심으로 이루어지는 UEJIP 장비표준화활동으로 구분될 수 있다. 본 연구는 Offshore Oil & Gas산업에서 적용되는 각종 국제표준을 분류하고 이를 기반으로 하여 진행되고 있는 선급 주도의 장비 표준화 활동 및 실제 프로젝트의 적용사례를 소개한다. This study analyzes the requirements for international standardization by studying the approach to international standardization of equipment and bulk materials in the offshore oil & gas industry, and describes the prioritization of standardized equipment and the result of standardization in the first stage. Currently, international standardization activities can be classified into three activities. First, international standardization activities of bulk materials led by three major domestic shipbuilders, second, JIP33 equipment standardization activities led by IOGP, and finally, And standardization activities of UEJIP equipment centered on classification society. This study classifies various international standards applied in the offshore oil & gas industry, and introduces the activities of standardization activities of class-leading equipment and actual application examples.

한성종,서영균,조맹익,김형우,박창수 한국산업융합학회 2019 한국산업융합학회 논문집 Vol.22 No.6

This paper is a study on the modeling of the quantity estimation model for offshore plant Material handling equipment in FEED(Front End Engineering Design) verification stage using system engineering approach which is an engineering design methods. The relevant engineering execution procedure is not systemized although the operation method and Material handling equipment selection with weight and space constraints is a key part of the FEED. Using the system engineering process, the stakeholder requirements analysis process, the system requirements analysis, and the final system architecture design were sequentially performed, and the process developed through the functional development diagram and Requirement traceability matrix (RTM) was verified. In addition, based on the established process, we propose a Material handling quantity estimation model and Quantity calculation verification Table that can be applied at the FEED verification stage and we verify the applicability through case studies.

해양플랜트 소형 유틸리티장비의 FEED 검증 프로세스에 대한 연구

한성종,박범,Han, Seong-Jong,Park, Beom 한국플랜트학회 2017 플랜트 저널 Vol.13 No.2

본 논문은 시스템엔지니어링기법을 이용하여 해양플랜트 산업의 소형 유틸리티 장비의 입찰단계에서 사용가능한 FEED 검증 수행모델에 대한 연구이다. 현재 국내 해양플랜트 기자재산업계는 해양플랜트에 진출하면서 프로젝트 수행에 따른 재정적 위험에 직면한 상태이며, 그 주요한 원인으로 기자재업체의 발주처(COMPANY 또는 EPC: Engineering, Procurement and Construction) 로부터 제공받은 FEED 결과물에 대한 검증능력부족으로 조사되었다. 이에 요구사항 분석, 기능, 성능분석 및 물리적아키텍처 구축프로세스를 순차적으로 적용하는 시스템 엔지니어링 기법을 간략화 한 FEED 설계 검증방법을 제안하고 이를 소형 유틸리티 장비(Air Compressor)를 대상으로 기존의 경험에 의존한 검증방법과 개발한 FEED 검증 모델을 적용한 결과를 비교함으로써 개발된 모델의 사용적정성을 검증하였다. This paper is a study on FEED validation model that can be used in the bidding stage of small utility equipment in offshore plant industry using system engineering technique. Currently, domestic marine plant equipment industry companies are faced with the financial risk of project execution as they enter marine plant. The major cause was the insufficient ability to verify the FEED output from the contractor (Engineering or Procurement and Construction) of the equipment manufacturer (COMPANY or EPC). Therefore, we propose FEED design verification method that simplifies the system engineering method that sequentially applies requirements analysis, function, performance analysis and physical architecture building process. Also, we verified the suitability of the developed model by comparing the results of applying the developed FEED verification model and the verification method that depends on the existing experience for the small utility equipment (Air Compressor).

poly-GaAs 채널을 갖는 3D NAND flash memory 전기적 특성 연구

한성종(Sung-Jong Han),오영택(Young-Taek Oh),송윤흡(Yun-Heub Song) 대한전자공학회 2016 대한전자공학회 학술대회 Vol.2016 No.11

In this paper, we investigated the threshold voltage (VT) dispersion and on-current in poly-GaAs used for a channel material in 3D NAND flash memory. Using simulation, stings of NAND flash memory with 12, 24, 36, and 48 cells were implemented and electrical properties were extracted. It is revealed that the on-current in poly-GaAs channel is larger than in poly-Si channel due to the difference in mobility. In addition, the VT dispersion tends to decrease as the numbers of stacked layers increase in case of poly-GaAs channel.

This paper was conducted to study the conditions for the manufacture and operation of artificial snow removal and ice-making test facilities so that the test equipment can be tested in a low-temperature environment using the polar environment performance test facility. The polar environment performance test Facility is designed to artificially simulate extreme environments up to -65 ℃, and is a mid-to-large low-temperature environment test facility that can perform performance tests on offshore plant equipment, ships, leisure, and offshore structures. To verify the safety of deck work of ships operating in polar environments, artificial snow removal and artificial ice making devices were manufactured, and we conducted research on various operating environments using these facilities. For the efficient operation of artificial snow and ice making facilities, it is important to continuously supply dry air, and it has been found that installing an additional heater at the tip of the nozzle is effective in preventing freezing.
