Claim 0:
1. A hydrocarbon fluid storage structure for storing hydrocarbon fluids therein, the structure comprising:
a base frame;
a storage vessel supported on the base frame so as to be arranged to contain hydrocarbon fluids therein;
a heater in communication with the storage vessel so as to be arranged to heat the hydrocarbon fluids in the storage vessel; and
a containment vessel supported on the base frame so as to fully surround the storage vessel so as to be arranged to contain any hydrocarbon fluids leaking from the storage vessel;
the storage vessel being fully received with a boundary of the containment vessel so as to define a containment space that is enclosed between a boundary of the storage vessel and the boundary of the containment vessel;
the boundary of the storage vessel being uninsulated such that heat can readily migrate from hydrocarbon fluids contained in the storage vessel into the enclosed containment space; and
the boundary of the containment vessel being heat insulated;
wherein the heater comprises (i) a heat exchanger vessel at least partially received within the storage vessel and containing a heat exchanger fluid therein, and (ii) a heat source received within the storage vessel and being arranged to heat the heat exchanger fluid; and
wherein the heat exchanger vessel includes (i) a lower portion received within the storage vessel and (ii) an upper portion received within the storage vessel, wherein the upper and lower portions are in communication with one another at two spaced apart locations so as to define a continuous closed loop flow path comprising a continuous recirculating loop within which the heat exchanger fluid is arranged to be continuously recirculated, and wherein the heat source is received within the lower portion of the storage vessel so as to be arranged to heat the heat exchanger fluid in the lower portion.
