FLNG projects combine the tightest specifications used for onshore plants with offshore constraints and floating conditions. Every effort has to be done in order to minimize the risk of weight increase deriving from the overdesign that one would implement to ensure the level of performance is met. Acid Gas Removal Unit (AGRU) and Liquefaction are two critical steps of the process that are affected by vessel movement. If this impact is not known accurately, optimization of the design will be difficult and may even involve a risk of off-spec gas being sent to the liquefied gas production unit which will then not operate properly.
