A New Concept for CNG Carriers and Floating CNG/Oil Processing and Storage Offshore Platforms (original) (raw)

Abstract

The collection and transportation of Natural Gas from small gas fields is the current focus of the Offshore Gas industry. To transport the gas from the field to the land distribution point there are two choices LNG or CNG. For the small fields and/or short transportation distance it appears that the best solution is CNG. The paper describes the application of a new containment tank system that has significant benefits for CNG carriers as well as Floating Oil/CNG Processing and Storage Offshore Platforms (FOCNGPSO) and Floating CNG Processing and Storage Offshore Platforms (FCNGPSO). Because of the shape of the CDTS advanced structural analysis is required to design it. Therefore the paper also presents the application of CAE methods using Altair Engineering's Hyperworks suite of advanced structural design, analysis and optimization tools. State-of-the-art optimization techniques like Topology and Free-Size optimization are showcased in this effort.
