Abstract: A method for heating a cargo on a watergoing vessel using an energy source (such as a heat source) on another watergoing vessel. The vessels may be underway. The energy may be transferred to the cargo via energy umbilicals configured to carry energy in a transfer fluid. The transfer fluid may be circulated in a cargo heat exchanger configured to move energy into the hot cargo. The energy source on the another watergoing vessel may be a propulsion motor, exhaust heat, or non-propulsion heat source. The method may include heating the hot cargo. The method may also include switching between heat sources when both vessels are configured to heat the hot cargo.

Abstract: A conventional containment vessel is retrofitted into a complete integral tank double-hull cargo containment vessel that includes a primary hull and a secondary hull disposed within the primary hull. The primary hull includes a topside deck structural member. The secondary hull includes an interior cargo containment tank. The secondary hull includes a topside structural member configured to seal the cargo containment tank. The primary hull is configured to serve as a first boundary between an operating environment of the vessel and the cargo. The secondary hull is configured to serve as a second boundary between the operating environment of the vessel and the cargo. The topside deck member of the primary hull and the topside structural member of the secondary hull are configured to provide a double-hull on the topside of the cargo containment tank.
