Conceptual design of an offshore LNG bunkering terminal

This study proposes the conceptual design of an offshore LNG bunkering terminal that would play a critical role in the LNG supply chain for LNG-fuelled ship propulsion. The principal functions of the LNG bunkering terminal include importing LNG from LNG carriers, storing it temporarily, and exporting the stored LNG to LNG bunkering shuttles or LNG-fuelled ships. One of the critical issues facing cargo operation from a safety point of view is the treatment of boiloff gas (BOG) generated from several sources in the storage systems of the bunkering terminal. Several methods of handling BOG seem feasible. The employment of a pressure vessel with a re-liquefaction system is considered the most effective and safe alternative.
