Floating LNG/CNG Processing and Storage Offshore Platforms Utilizing a New Tank Containment System

摘要

Current interest in Natural Gas offshore systems is focused on the Floating Oil/LNG Processing and Storage Offshore Platforms (FOLNGPSO) Floating LNG Processing and Storage Offshore Platforms (FLNGPSO, Floating Oil/CNG Processing and Storage Offshore Platforms (FOCNGPSO) Floating CNG Processing and Storage Offshore Platforms (FCNGPSO). A number have been built and many more are in design. A new tank containment system which has shown significant operation and acquisition cost benefits is even more beneficial to the FOGNGPSOs and FCNGPSOs especially its ability to withstand sloshing loads in partially filled LNG tanks. The paper reports on the benefits of the Cubic Doughnut tank containment system on the supporting platform design especially its ability to operate with liquid levels in the tank from empty to full.
