A STUDY ON THE LOCALIZATION OF DESIGN TECHNOLOGIES FOR LNG STORAGE TANKS UNE ETUDE SUR LA LOCALISATIN DES TECHNOLOGIES DE CONCEPTION POUR LES RESERVOIRS DE STOCKAGE DE GNL

摘要

Recently, the R&D division of Korea Gas Corporation (KOGAS) developed the design technologies for the commercial full containment 9% Ni type and the above ground membrane type with the capacity of 140,000 m~3 respectively. To localize the design technologies, a Pilot LNG storage tank with the capacity of 1,000 m~3 needed to be first designed and built. Through the development and operation of the pilot LNG storage tank, KOGAS has accumulated the various core technologies, and now has the capability of designing for the commercial LNG storage tanks. With the use of pilot LNG storage tank, numerous LNG behavior trials will be carried out in the 1,000-m~3 pilot tank to develop the technology that can optimize the operation of LNG storage tanks and minimize the forming of BOG during the summer, where the LNG should be stored for a long period of time. Also for a long-term project, KOGAS plans to develop the technology that can dramatically extend the remaining life of LNG storage tanks by acquiring technology that can estimate and predict the remaining life of LNG tanks.
