SYSTEM AND METHOD FOR SMALL SCALE MARINE TRANSPOATION OF CRYOGENIC HYDROCARBONS

摘要

A system and method for small scale marine transportation of cryogenic hydrocarbons is described. A small scale cryogenic hydrocarbon marine transportation system includes a plurality of swap barges each having a cryogenic hydrocarbon capacity of 25,000 m3 or less, and a semisubmersible transfer ship, where the plurality of swap barges and the semisubmersible transfer ship cooperate to provide uninterrupted delivery of cryogenic hydrocarbons to a marine delivery location, and access to the marine delivery location is through an inlet or an estuary, wherein the semisubmersible transfer ship transports each of the plurality of swap barges on deck across open water, and the plurality of swap barges self- propel through the inlet or estuary to the inland water delivery location.
