Description

CRYOGENIC ARTICULATED BARGE
CROSS REFERENCE TO RELATED APPLICATIONS This application seeks priority to United States Provisional Application 61/054,718, filed May 20, 2008, the entirety of which is incorporated by reference.
FIELD OF THE INVENTION
[0001] Aspects of the invention relate to liquefied natural gas (LNG) ships. More specifically, aspects of the invention relate to cryogenic articulated barges for shipment of LNG from vessel transport ships to on-shore unloading facilities.
BACKGROUND INFORMATION
[0002] Currently, LNG ships that have been built have a cargo storage capacity in excess of 135,000 to 150,000 m3 . Plans for newer ships in the LNG transportation business call for vessel sizes to exceed 200,000 m3 cargo capacity as new technologies have allowed for greater economies of scale for transoceanic shipping,
10003] As the cargoes of LNG vessels increase, there is growing safety concern in the United States and abroad. More specifically, safety concerns relating to explosion of these vessels has taken a paramount importance as the vessels have a greater destructive capability in the event of a catastrophic failure. Thus, the increasing size of ships often results in additional safety measures being taken by harbor.owners. These safety measures can include, unfortunately, exclusion of the LNG vessels from close to shore or onshore unloading facilities near population centers. The LNG vessels, therefore, do not have access to load centers that require the use of LNG on a constant basis. A pipeline must be used to transport LNG from a deepwater offloading port to onshore facilities, thereby increasing costs of the overall transportation of the LNG. CRYOGENIC ARTICULATED BARGE
[0004] There is a need to provide for transportation of LNG cargoes in a cost- effective manner.
[0005] There is an additional need to provide for transportation of LNG cargoes directly to the point of use customers that require large volumes of LNG.
[0006] There is an additional need to provide for transportation of LNG in a safe manner that is consistent with regulatory agency requirements.
SUMMARY OF THE INVENTION
[0007] It is therefore an objective of an aspect of the invention to provide for transportation of LNG cargoes in a cost-effective manner.
[0008] There is an additional objective of an aspect of the present invention to provide for transportation of LNG cargoes directly to the point of use customer who uses large volumes of natural gas.
[0009] It is an additional objective of an aspect of the invention to provide for transportation of LNG in a safe manner that is consistent with regulatory agency requirements.
[0010] The objectives of the invention are achieved as illustrated and disclosed. In an exemplary embodiment of the invention, a method of transportation of LNG is presented, comprising providing a LNG transport ship in excess of 100,000 cubic meters of capacity, docking a cryogenic articulated barge to the LNG transport ship, unloading LNG from the LNG transport ship to the cryogenic articulated barge, transporting the cryogenic articulated barge to an on-shore unloading facility, and unloading the cryogenic articulated barge at the unloading facility. CRYOGENIC ARTICULATED BARGE [0011] In another embodiment, the method is performed such that the cryogenic articulated barge is a double hulled vessel.
[0012] In another embodiment, the cryogenic articulated barge has cargo holds that are reinforced to prevent leakage.
[0013] In another embodiment, the method further comprises operating the cryogenic articulated barge as a ferry system back and forth to the LNG transport ship.
[0014] In a further embodiment, the method is accomplished such that the cryogenic articulated barge has a cargo capacity less than 30,000 cubic meters.
[0015] In a still further embodiment, the method is further accomplished to perform the step of cooling the LNG on the cryogenic articulated barge during transport to the on-shore unloading facility.
[0016] In a still further embodiment, the method further comprises warming the LNG on the cryogenic articulated barge at the delivery unloading facility.
BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 illustrates a cryogenic barge used for transporting LNG from, a large container ship to an on-shore unloading facility,
DETAILED DESCRIPTION
[0018] Referring to Figure 1, a method of shipping LNG from a LNG container ship to an on-shore offloading facility is illustrated. A cryogenic articulated barge 10 is used to offload LNG from a LNG container ship 20. The LNG container ship 20, in an exemplary embodiment, has a capacity of greater than 100,000 m3. Due to the size of the LNG container ship 20, the LNG container ship is not permitted in shallow waters near population centers due to the risk of explosion. In conventional practice, these large LNG container ships 20 must dock at a CRYOGENIC ARTICULATED BARGE remote offloading facility thereby allowing their LNG cargo to be shipped by pipeline to the ultimate end user. This additional pipeline transportation increases the overall cost of LNG to consumers. The size of the LNG container ship 20 necessitates that the pipeline is of a sufficient length to prevent population centers from the risk of explosion.
[0019] Cryogenic articulated barges 10 are used to ferry LNG cargo from the LNG container ship 20 to an onshore delivery point 30. The cryogenic articulated barge 10 is a shallow draft vessel that will allow access to shallow depth port facilities that can accomodate cryogenic articulated barges. The cryogenic articulated barge 10 is provided with holds that prevents LNG from escaping to the environment. The hold can be a reinforced structural steel container that is cryogenically treated to maintain the LNG cargo at a desired temperature. The systems used to maintain the cargo at the desired temperature may be powered, for example, by the LNG itself. The cryogenic articulated barge 10 is a double hulled vessel designed to prevent leakage from occurring to the environment in case either the inner hull or outer hull is penetrated. Additionally, the cryogenic articulated barge in the illustrated embodiment as a cargo hold less than 30,000 m3.
[0020] The onshore unloading point 30 is configured to accept transfer of material from the hold of the cryogenic articulated barge 10 for incorporation into a pipeline or at a terminal where the cryogenic LNG may be warmed or stored as appropriate.
[0021] The cryogenic articulated barge 10 may use seawater to warm the LNG, as desired, to prevent from having to utilize LNG as a fuel source for warming the cargo in the hold.
[0022] In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will, however, be CRYOGENIC ARTICULATED BARGE evident that various modifications and changes may be made thereunto without departing from the broader spirit and scope of the invention as set forth in the appended claims, The specification and drawings are accordingly to be regarded in an illustrative rather than in a restrictive sense.
