The objective of this paper is to address design considerations for offshore liquefaction process. These considerations are for the developments of technologies for both the liquefaction process and equipment, the effects of motion, the transfer of LNG between the offshore facilities to LNG ships, the operational flexibility and availability of the plants and the safety concerns due to the congestion of areas in the offshore facilities. Process efficiency is less important than process simplicity and overall safety. Offshore LNG transfer needs to meet the marine and environmental challenge. Safety considerations on the plant layouts, spacing and level of risks are important. This paper discusses these aspects and summarizes the current thinking on these issues.
