Heating a hot cargo barge using recovered heat from another vessel using an umbilical
A system and method for heating a hot cargo on a watergoing vessel using a heat source on another watergoing vessel. The heat may be transferred to the hot cargo via heat umbilicals configured to carry heat in a heat transfer fluid. The heat transfer fluid may be circulated in a hot cargo heat exchanger configured to move heat into the hot cargo. The heat 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.
1. A system for heating, the system comprising:
a first watergoing vessel comprising:
a first heat source; and
a first heat exchanger in thermal communication with the first heat source;
a second watergoing vessel comprising:
a storage tank configured for hot cargo; and
a second heat exchanger in thermal communication with the storage tank; and
a heat transfer connector configured to circulate a heat transfer fluid between the first heat exchanger and the second heat exchanger.
2. The system of claim 1 further comprising:
at least one pump configured to move the heat transfer fluid along the heat transfer connector.
3. The system of claim 1 , wherein the second watergoing vessel further comprises:
a second heat source.
4. The system of claim 3 , wherein the second vessel further comprises:
a valve assembly configured to switch heating of the second heat exchanger between the first heat source and the second heat source.
5. The system of claim 4 , further comprising:
a temperature switch configured to control the valve assembly and responsive to at least one of: i) a temperature of the storage tank and ii) a temperature of the second heat exchanger.
6. The system of claim 1 , further comprising:
a third watergoing vessel comprising:
an additional storage tank configured for hot cargo; and
a third heat exchanger in thermal communication with the additional storage tank; and
an additional heat transfer connector configured to circulate the heat transfer fluid between the first heat exchanger and the third heat exchanger.
7. The system of claim 6 , wherein the heat transfer connector and the additional heat transfer connector are configured to circulate the heat transfer fluid between the watergoing vessels in series.
8. The system of claim 6 , wherein the third watergoing vessel is disposed between the first watergoing vessel and the second watergoing vessel.
9. The system of claim 1 , wherein the heat transfer connector is thermally insulated.
10. The system of claim 1 , wherein the first heat source is configured to provide propulsion for the first watergoing vessel.
11. The system of claim 10 , wherein the first heat source is configured to provide propulsion and heat simultaneously.
12. The system of claim 1 , wherein the first watergoing vessel and the second watergoing vessel are under weigh.
13. The system of claim 1 , wherein the heat connector comprises a discharge umbilical and a return umbilical.
14. The system of claim 13 , wherein each of the umbilicals comprise a quick disconnect fitting.
15. The system of claim 1 , wherein the second watergoing vessel is a complete integral tank double-hull cargo containment vessel.
16. A system for heating, the system comprising:
a first marine vessel comprising:
a first heat source; and
a first heat exchanger coupled to the first heat source;
a second marine vessel comprising:
a storage tank configured for heated cargo; and
a second heat exchanger coupled to the storage tank; and
a heat transfer connector circulating a thermal transfer fluid between the first heat exchanger and the second heat exchanger.
17. The system of claim 16 , wherein the first marine vessel is a tug boat and the second marine vessel is a cargo barge.
18. The system of claim 16 , wherein the thermal transfer fluid is an exhaust heat from a propulsion motor of the first marine vessel.
19. The system of claim 16 , wherein the first marine vessel and the second marine vessel are inland water going vessels.
20. The system of claim 16 , wherein the heated cargo is asphalt and sulfur.
