Dockside ship-to-ship transfer of LNG
Systems and methods for dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.
1. A method for dockside vessel regasification of liquefied natural gas (LNG), the method comprising:
transferring LNG from a LNG carrier to a mooring dock, wherein the LNG carrier is moored at the mooring dock;
managing boil-off gas generated as the LNG is transferred from the LNG carrier to the mooring dock;
transferring the LNG from the mooring dock to a regasification vessel;
regasifying the LNG into regasified natural gas onboard the regasification vessel; and
delivering the regasified natural gas to a receiving dock using a jointed arm configured to transfer natural gas to a natural gas pipeline on the receiving dock.
2. The method of claim 1 , wherein the LNG is transferred from the mooring dock to a cargo tank on the regasification vessel.
3. The method of claim 1 , wherein the LNG carrier is located on a first side of the mooring dock, and the regasification vessel is located on a second side of the mooring dock.
4. The method of claim 1 , wherein the LNG carrier is located on a first side of the mooring dock, wherein the regasification vessel is located on a second side of the mooring dock, wherein the regasification vessel is rotationally coupled to the jointed arm, and wherein the jointed arm is located on the receiving dock.
5. The method of claim 1 , wherein the LNG carrier is located on the same side of the mooring dock as the regasification vessel.
6. The method of claim 1 , wherein the LNG is transferred from the LNG carrier to the mooring dock, and then to the regasification vessel, in an uninterrupted flow.
7. The method of claim 1 , wherein transferring LNG from the LNG carrier comprises transferring LNG through a manifold system comprising liquid hoses and liquid conduits that extend along the mooring dock.
8. The method of claim 1 , wherein the mooring dock is the same dock as the receiving dock.
9. The method of claim 1 , where in the mooring dock is adjacent to the receiving dock.
10. A system for dockside vessel regasification of liquefied natural gas (LNG), the system comprising:
a LNG carrier comprising LNG;
a mooring dock, wherein the mooring dock receives the LNG from the LNG carrier;
a manifold system coupled between the LNG carrier and the mooring dock, the manifold system comprising:
a plurality of liquid conduits;
at least one vapor hose that manages boil-off gas generated as the LNG is transferred through the plurality of liquid conduits; and
a plurality of dry break release couplings coupled to the plurality of liquid conduits and the at least one vapor hose;
a regasification vessel, wherein the regasification vessel receives LNG from the mooring dock, and wherein the regasification vessel further comprises a LNG regasification system; and
a jointed arm, wherein a first coupled end of the jointed arm is rotationally coupled to the regasification vessel and a second coupled end of the jointed arm is coupled to a receiving dock, and the jointed arm accepts regasified natural gas from the regasification vessel and delivers the regasified natural gas to the receiving dock.
11. The system of claim 10 , wherein the jointed arm is coupled to a natural gas pipeline on the receiving dock and delivers natural gas into the natural gas pipeline.
12. The system of claim 10 , wherein the mooring dock is the same dock as the receiving dock.
13. The system of claim 10 , wherein the mooring dock is adjacent to the receiving dock.
14. The system of claim 10 , wherein the jointed arm comprises a quick release system and the regasification vessel comprises an emergency release coupling.
15. A system for dockside vessel regasification of liquefied natural gas (LNG), the system comprising:
a LNG carrier comprising LNG;
a regasification vessel, wherein the regasification vessel receives LNG from the LNG carrier, and wherein the regasification vessel further comprises a LNG regasification system;
a manifold system coupled between the LNG carrier and the regasification vessel, the manifold system comprising:
a plurality of liquid hoses; and
at least one vapor hose that manages boil-off gas generated as LNG is transferred through the plurality of liquid hoses; and
a jointed arm, wherein a first coupled end of the jointed arm is coupled to the regasification vessel and a second coupled end of the jointed arm is coupled to a dock, and wherein the jointed arm accepts regasified natural gas from the regasification vessel and delivers the regasified natural gas to a pipeline on the dock.
16. The system of claim 15 , wherein transponders detect motion of the regasification vessel.
17. The system of claim 15 , wherein the regasification vessel comprises an emergency release coupling, and the emergency release coupling comprises a radio communication system and a pneumatic actuation system.
