Cost Effectiveness of 2-Row Membrane System for FLNG

Apr 3, 2012
Herbert Moon
One of the most critical issues in engineering and design of FLNG is to reduce top side weight along with its load distribution to the sub-structure. Concentrated top side loads will result in an increase in hull structure costs. The developed 2-row containment system allows flexibility of top side...

Carbon Capture Ready Heavy Oil Extraction and Upgrading
