Systems and methods for floating dockside liquefaction of natural gas

A system for floating dockside liquefaction of natural gas comprising:

• natural gas pretreatment facility located onshore proximate a dock, wherein the onshore natural gas pretreatment facility process pipeline quality gas into pretreated natural gas;
• a floating liquefaction unit moored at the dock, wherein the floating liquefaction unit further comprises a natural gas liquefaction module on a deck, and an LNG storage tank for storing produced LNG below the deck;
• a pipeline coupling the onshore pretreatment facility to the dock, wherein the pipeline transports pretreated natural gas onto the dock;
• a high pressure gas arm fluidly coupling the pipeline to the floating liquefaction unit, wherein the gas arm transfers pretreated natural gas to the floating liquefaction unit;
• and
• an onshore storage facility located proximate the dock configured to store condensate removed from natural gas onboard the floating liquefaction unit.

A method for floating dockside liquefaction of natural gas, comprising:

• pretreating natural gas for shipboard liquefaction at an onshore pretreatment facility proximate a dock;
• transporting the pretreated natural gas by pipeline from the onshore pretreatment facility to a floating liquefaction unit moored at the dock;
• liquefying the natural gas onboard the floating liquefaction unit to form LNG;
• storing the LNG onboard the floating liquefaction unit;
• transferring the LNG from the floating liquefaction unit to a receiving LNG carrier for transport to the location of use;
• and
• removing condensate from the natural gas onboard the floating liquefaction unit and subsequently transferring the condensate to an onshore storage facility located proximate the dock for storage.
