New offshore LNG concepts

摘要

Liquid Natural Gas (LNG) is becoming an increasingly important energy source. Floating LNG production on LNG FPSOs is considered to be a realistic option for gas field developments nowadays and several innovative gas-receiving terminal concepts are presently being investigated. This report from MARIN, the Maritime Research Institute of The Netherlands, gives an update. FLOATING LNG production and offloading is new and challenging. The required amount of process equipment is massive and it has not been applied on a moving structure before. Therefore special attention has to be paid to the motion levels at the structure. Motion reduction during the design of the hull and effective control of the heading during operation are two aspects under consideration. The amount of process equipment onboard results in large barge sizes (400m plus), which makes the effective and safe mooring of the structure in survival conditions a subject that needs careful consideration.
