Abstract
Abstract An efficient marine/rail interface method provides for the discharge of import containers from a container ship to well cars, in the simultaneous discharge of export containers from well cars to an intermodal transition zone. Once the container ship is sufficiently unloaded, export containers from the intermodal transition zone may be loaded onto the container ship. Simultaneously, the ship may be discharged of further import containers. The method also provides for reworking of well cars at an inland port rework area, in communication between the marine/rail interface facility and the inland port rework area via a corridor. A data management system manages the intermodal exchange of containers between ship, rail and truck utilizing a common user electronic data management system.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
254 words
A method of exchanging export and import containers between a container ship and land transports, comprising the steps of: (a) discharging a first plurality of import containers from a vertical cell to a location adjacent to the container ship, transporting each of the containers of the first plurality from the location to an intermodal rail area, thereby creating a cleared vertical cell; (b) discharging a first plurality of export containers from a plurality of land transports in the intermodal rail area into an intermodal transition zone, and loading the plurality of land transports with import containers in the intermodal rail area; and then (c) performing a simultaneous load and discharge of the container ship and the land transports comprising the substantially synchronous steps of: (1) unloading one of the export containers from the land transport in the intermodal rail area; based on the characteristics of the unloaded export container, transporting the unloaded export container to the location adjacent to the container ship, or transporting the unloaded export container to the intermodal transition zone and transporting one of the export containers from the intermodal transition zone to the location adjacent to the container ship; and loading the export container from the location adjacent to the container ship into the cleared vertical cell; and (2) discharging one of the import containers from a next vertical cell in the container ship; transporting the discharged import container to the intermodal rail area; and loading the discharged import container in the intermodal rail area onto the unloaded land transport.
Claim 2
Independent Claim
254 words
A method of exchanging export and import containers between a container ship and land transports, comprising the steps of: (a) discharging a first plurality of import containers from a vertical cell to a location adjacent to the container ship, transporting each of the containers of the first plurality from the location to an intermodal rail area, thereby creating a cleared vertical cell; (b) discharging a first plurality of export containers from a plurality of land transports in the intermodal rail area into an intermodal transition zone, and loading the plurality of land transports with import containers in the intermodal rail area; and then (c) performing a simultaneous load and discharge of the container ship and the land transports comprising the substantially synchronous steps of: (1) unloading one of the export containers from the land transport in the intermodal rail area; based on the characteristics of the unloaded export container, transporting the unloaded export container to the location adjacent to the container ship, or transporting the unloaded export container to the intermodal transition zone and transporting one of the export containers from the intermodal transition zone to the location adjacent to the container ship; and loading the export container from the location adjacent to the container ship into the cleared vertical cell; and (2) discharging one of the import containers from a next vertical cell in the container ship; transporting the discharged import container to the intermodal rail area; and loading the discharged import container in the intermodal rail area onto the unloaded land transport.
Claim 3
Dependent Claim
51 words
The method as claimed in claim 1, further comprising the step of discharging a second plurality of import containers from an on-deck stow of the container ship to the location adjacent to the container ship, prior to the step of discharging the first plurality of import containers from the vertical cell.
Claim 4
Dependent Claim
66 words
The method as claimed in claim 1, wherein step (c)(1) further comprises, for each land transport: (d) unloading the export containers from the land transport until a well car in the land transport is empty; (e) loading a portion of the import containers onto the land transport until the well car in the land transport is full; and (f) obtaining a next well car to unload.
Claim 5
Dependent Claim
68 words
The method as claimed in claim 3, wherein step (a) is performed by a crane, step (b) is performed by one of a plurality of mobile lifts, step (d) is performed by one of the plurality of mobile lifts, the transporting step of step (e) is performed by one of the plurality of mobile lifts, and step (f) is performed by one of the plurality of mobile lifts.
Claim 6
Dependent Claim
29 words
The method as claimed in claim 1, further comprising the step of transporting the import containers to a rework area and transporting the export containers from the rework area.
Claim 7
Dependent Claim
22 words
The method as claimed in claim 5, wherein the containers are transported to and from the rework area via an intermodal rail.
Claim 8
Dependent Claim
15 words
The method as claimed in claim 5, wherein the rework area is an inland port.
Claim 9
Dependent Claim
19 words
The method as claimed in claim 5, further comprising the step of reworking the containers in the rework area.
Claim 10
Dependent Claim
25 words
The method as claimed in claim 1, further comprising the step of tracking the import containers and the export containers in a data management system.
Claim 11
Dependent Claim
25 words
The method as claimed in claim 9, wherein the tracking step comprises sending a location and contents of the container to the data management system.
Claim 12
Dependent Claim
20 words
The method as claimed in claim 1, further comprising the step of clearing a second one of the vertical cells.
Claim 13
Dependent Claim
24 words
The method as claimed in claim 11, wherein the second one of the vertical cells is on an opposite side of the container ship.
Claim 14

The method as claimed in claim 1, further comprising the step of determining and selecting import containers to load on the land transports based on container characteristics of the import containers.
Claim 16
Dependent Claim
32 words
The method as claimed in claim 1, further comprising the step of determining and selecting export containers to load in the cleared vertical cell based on container characteristics of the export containers.
Claim 17
Dependent Claim
19 words
