[0002] Field of the Invention The present disclosure generally relates to methods and systems for securing shipping containers on cargo vessels. More particularly, the present disclosure relates to methods and systems for lashing shipping containers that are less dependent on manual labor for deployment. Background Art

[0003] Background of the Invention When navigating through rough seas, cargo vessels sometimes lose large numbers of shipping containers overboard in accidents. As vessels have increased in size and shipping containers are stacked higher, the design of conventional lashing systems that have been used for many years can no longer provide an acceptable level of restraint. The movement of upper containers becomes greater due to the pitching and rolling of the vessel caused by wave effects. This movement results in higher acceleration levels for upper containers, which can make shipping containers unstable.

[0004] Examples of known methods and systems for securing shipping containers on cargo vessels are described in International Application Publication No. WO2022 / 169484, published August 11, 2022, which is incorporated herein by reference.

[Modes for carrying out the invention]

[0011] Detailed explanation The present invention is capable of various modifications and alternative forms, and specific embodiments are illustrated in the drawings and description. However, it should be understood that the drawings and description are not intended to limit the invention to the specific forms disclosed herein, but rather to encompass all modifications, equivalents, and alternatives available to those skilled in the art.

[0012] Referring to Figures 1 to 5E, a preferred embodiment of a securing device for deploying lashing material to fix a stack of transport containers will be described.

[0013] Figure 1 shows a cargo ship 100 having a hatch top 102, on which containers are stacked as a stack 108 consisting of multiple rows. The securing device has a base 24, a support 18, securing members 106, and optionally another support 19 and another securing member 107. The base 24 is located near the center of the cargo ship 100. The base 24 is configured to be coupled to the deck 104 of the cargo ship 100. As will be further detailed below, the securing members 106 (and securing members 107, if provided) are divided into segments. The support 18 and / or 19 are connectable to an interlocking system for one or more shipping containers stacked as a container row.

[0014] In another embodiment, the base 24 may be configured to be connected to the lashing bridge of the cargo ship 100.

[0015] In another embodiment, the fastening material 107 and the support 19 may be connected to another foundation located at a position offset from the foundation 24.

[0016] Tension is applied to the securing members 106 and 107 in order to stabilize the transport containers stored on the cargo ship 100 in a position between a first row of transport containers stacked on the starboard side of the cargo ship and connected to a support 18, and a second row of transport containers stacked on the port side of the cargo ship and connected to a support 19.

[0017] Figures 2 and 3 show various configurations of the laminate 108 with varying heights of the first (i.e., leftmost) column. For example, the height varies between the heights of 7 to 9 containers stacked from the hatch top 102. In this example, the support 18 is attached to the top of the first column. As a result, the span of the fasteners 106 can be seen to change.

[0018] To accommodate this variation, the fastening material 106 is divided into segments, each containing either a wire rope (20a, 20b, or 20c) of a standard length, one of several connecting ropes (26a, 26b, 26c) of different lengths, or a single connecting rope of a standard length sufficient to accommodate the variation. Releaseable connectors (22a, 22b, or 22c) connect the connecting ropes (26a, 26b, 26c) to the wire ropes (20a, 20b, 20c), respectively, forming the fastening material 106 shown in Figure 1.

[0019] As an example, the wire rope (20a, 20b, 20c or 20d) may have a length of 78.33 feet and may have a diameter of 3 / 4 inch. In this way, the wire ropes (20a, 20b, 20c, 20d) can be stored horizontally on the deck 104, as shown as the wire rope 20d. The connecting rope 26a may have a length of at least about 14.8 feet, the connecting rope 26b may have a length of at least 8.4 feet, and the connecting rope 26c may have a length of at least about 5 feet. Alternatively, the connecting ropes 26a, 26b, 26c may have the same standard length of at least about 14.8 feet.

[0020] To attach the lashing member 106, a wire rope (20a, 20b or 20c) is prepared. The wire rope (20a, 20b or 20c) can be stored horizontally on the deck 104, and is illustrated as the wire rope 20d. Then, any one of the connecting ropes (26a, 26b, 26c) may be selected based on the height of the first row, the standard length of the wire rope (20a, 20b, 20c), and the installation position of the foundation 24, or a connecting rope with a standard length may be used. The connecting rope (26a, 26b or 26c) is attached to a pulling winch 32 (for example, a manual winch accessible to an operator on the deck), and the connecting rope (26a, 26b or 26c) is coupled to one end of the wire rope (20a, 20b or 20c) via a releasable connector (22a, 22b or 22c). Next, the lashing member 106 is deployed by lifting the other end of the wire rope (20a, 20b, 20c), as described below.

[0021] Referring to FIGS. 1 and 2, the connecting ropes (26a, 26b or 26c) and the tension winch 32 are configured to accommodate side laminates of different heights. Further, the tension of the lashing members 106 can be adjusted by winding or unwinding the connecting ropes with the tension winch mounted on the foundation 24. Compression guides 28 (FIG. 2) are arranged between the rows of the laminate 108 to preload the opposite sides of the containers when tension is applied to the lashing members 106 and 107. An example of a compression guide is exemplified in application No. PCT / US2023 / 013349, filed on Feb. 17, 2023.

[0022] FIG. 4 shows the support 18. In a preferred embodiment, the support 18 comprises a flat rack. The flat rack has a length of 45 feet, such that when the interlocking system at location 36 is coupled to a typical 40-foot container, the flat rack has an overhanging portion 16 extending from the typical 40-foot container. The overhanging portion 16 is provided with a passive lock. As described in more detail below, the passive lock includes a socket configured to receive and retain a plug mounted to an end of a wire rope 20 (i.e., one of the wire ropes 20a, 20b, 20c shown in FIGS. 2 and 3). As mentioned above, the end of the wire rope 20 to which the plug is attached is lifted from the deck 104. Specifically, the end of the wire rope 20 is lifted using an electric retraction winch 10 attached to the retraction rope 12, and is further attached to the electric retraction winch 10.

[0023] The plug 14 is retained in the passive lock using a sequence of steps shown in FIGS. 5A-5E (with a portion of the portion 16 cut away to show the passive lock).

[0024] Referring to Figure 5A, the plug 14 is attached to the pull-in rope 12. The plug 14 can provide housing for the tension monitor and its associated electronics and battery. In this figure, the plug 14 is not yet coupled to the wire rope 20. The electric pull-in winch 10 lowers the plug 14 at the end of the pull-in rope 12 until the plug fits into the bucket 30, as shown in Figures 5B and 2.

[0025] Referring to Figure 5B, the wire rope 20 stored on deck 104 is connected to the plug via a releaseable connector 34. The electric retraction winch 10 lifts the plug 14 at the end of the retraction rope 12 until the plug 14 passes through the overhang 16, as shown in Figure 5C.

[0026] Referring to Figures 5D and 2, the wire rope 20 is partially wound up using the tension winch 32 and connecting rope. This partial winding causes the plug 14 to move and tilt, so that the plug 14 is received into the socket of the passive lock. This is because the central axis of the socket is inclined with respect to the vertical and is in substantially contact with the circumferential surface of the rope guide of the electric retract winch.

[0027] If Figure 5D showed a support 19 instead of support 18, the partial winding of the wire rope 20 would cause the plug 14 to move and tilt in the opposite direction to that shown in Figure 5D. Despite this direction, the plug 14 would still be accepted into another socket of the passive lock.

[0028] Therefore, optionally, passive locks of the same design can be used on either the starboard or port side of the stack of transport containers. In another embodiment, the passive lock may have only one of the two sockets, requiring two different designs of passive locks.

[0029] Referring to Figures 5E and 1, the plug 14 is lowered again at the end of the pull-in rope 12 by the electric pull-in winch 10. However, once accepted into the socket, the plug 14 is held in the socket, and at that time, additional tension is applied to the securing material 106 to stabilize the transport container stored in the cargo ship 100.

[0030] Figure 6 illustrates another preferred embodiment in which the support 18 has vertical beams, allowing another container to be stacked on top of the support 18 without interfering with the electric retraction winch 10.

[0031] Figures 7A and 7B illustrate another preferred embodiment, in which the electric retraction winch 10 is retracted below the floor surface of the support 18. The plug 14 also has a spherical surface configured to engage with the socket. Figure 7A shows the plug 14 passing through the passage of the passive lock. Figure 7B shows the plug 14 being held by the shoulder within the socket of the passive lock.
