Abstract

Recently, for such reasons as its inexpensive price and eco-friendliness, LNG has been under the limelight as an alternative fuel for vessels and is expected to grow rapidly in the industry. However, the technology level of domestic shipbuilders in manufacturing the cryogenic pump designed to supply LNG for vessels is so low that design and manufacturing technology of core parts are in urgent need. Therefore, this study describes the stepwise development procedure of cryogenic submerged centrifugal pump for ship LNG supply system. And it aims to suggest practical and specific development methods of the pump by approaching the characteristics of each step and major development items from the standpoint of engineering and management.

최근, LNG는 저렴한 가격과 친환경적 연료 등의 이유로 선박용 대체연료로 각광을 받고 있으며, 그 수요량도 급성장이 예상된다. 그러나, 선박의 LNG 연료공급을 위한 극저온펌프(Cryogenic Pump) 제작과 관련한 국내 기술력은 매우 미흡한 실정으로 핵심 부품의 설계와 제작 기술이 절실한 시점이다. 따라서, 본 연구는 선박용 LNG 공급 시스템용 극저온 잠액식 원심펌프(Cryogenic Submerged Centrifugal Pump)의 단계별 개발절차에 대하여 기술하였다. 그리하여, 각 단계별 특성 및 주요 개발항목을 공학적이고 관리적인 측면에서 접근함으로써 실질적이고 구체적인 개발방법을 제시하는데 연구 목적을 두었다.
