Abstract: An improvement to an LNG carrier having a vaporizer on board said LNG carrier for vaporizing the LNG to a gaseous state is disclosed. The LNG carrier includes a source of heat for said vaporizer; an intermediate fluid circulating between said vaporizer and said source of heat; and one or more pumps for circulating said intermediate fluid between said vaporizer and said source of heat. The improvement includes equipment connections for adding at least one additional source of heat for said vaporizer, pre-installed flow conduits between said vaporizer and said equipment connections, and valves for isolating said pre-installed flow conduits from said vaporizer.

Abstract: An LNG carrier having onboard regasification capability that includes a primary source of heat for regasifying the LNG is disclosed. Further, the LNG carrier includes at least one secondary source of heat for regasifying the LNG, a vaporizer, an intermediate fluid, and a pump that circulates said intermediate fluid through said vaporizer and said primary and secondary sources of heat.
