Description

Technical Field

[0001] The present application relates to the field of ship outfitting arrangement and research and development technology, and in particular to a transfer channel of an ultra-wide moon pool. Background Art

[0002] Currently, the maximum width of a moonpool on a conventional research vessel is approximately one-fifth the ship's width. Due to its unique characteristics, a moonpool cannot be located close to the side and is typically located near the ship's centerline. Other compartments must be located on either side of the moonpool. Passageways are provided on both sides of the moonpool compartment for transporting equipment, carts, and personnel.

[0003] After the moon pool occupies a certain width of the ship, and after reserving passages for various equipment transportation, trolleys, and personnel, the size of the rooms and cabins on both sides of the main deck of the moon pool is limited, and they will become small cabins to a large extent, which is not conducive to the effective division and utilization of the ship's cabins.

[0004] All equipment that needs to be transported through the moonpool must be transported using trolleys. These lightweight items, typically weighing less than one ton, are transported using trolleys. Some heavy scientific research equipment, such as remotely operated vehicles (ROVs), can weigh up to four tons and cannot be transported through the side passages of the moonpool using trolleys.

[0005] Due to the characteristics of moonpool transportation, there is currently no precedent for deploying ROVs in the moonpool of conventional scientific research vessels. Only lightweight detection equipment such as conductivity temperature depth (CTD) meters are deployed. ROVs are lifted by a deck crane to the side A-frame for deployment. Summary of the Invention

[0006] An embodiment of the present invention provides an ultra-wide moonpool transfer channel, which is used to solve the problem that traditional channels beside the moonpool can only transport light equipment. It can enable equipment weighing less than 5 tons to be successfully transferred over the moonpool.

[0007] The embodiment of the present invention provides a transfer channel for an ultra-wide moon pool, comprising: a moon pool hatch, a track, and a trolley;

[0008] The bottom surface of the moon pool hatch cover is provided with a longitudinal and transverse frame structure according to the preset load tonnage, and the moon pool hatch cover serves as a transfer channel carrier;

[0009] The top surface of the moon pool hatch cover and the main deck adjacent to the moon pool hatch cover are provided with grooves corresponding to the track, and screw plug sleeves with internal threads are embedded in the grooves;

[0010] The rails are arranged on the main deck and the moon pool hatch, and are detachably connected with the screw plug sleeves by bolts;

[0011] The trolley is arranged on the track, and the trolley can move along the extending direction of the track on the track through the pulleys at the bottom of the trolley. The equipment can be transported over the moon pool through the trolley via the track, and the total weight of the equipment and the trolley is less than or equal to the preset load tonnage.

[0012] In some embodiments, for a ship whose main deck where the moon pool cabin is located is not laid with wooden planks, when the track is not installed, a plug matching the plug-type sleeve is used to plug it.

[0013] In some embodiments, the surface of the plug is flush with the main deck, and the top of the plug has a cross-grooved recess for tightening or disassembling operations.

[0014] In some embodiments, for a ship whose main deck where the moon holding cabin is located is laid with wooden planks, a cushion block with the same height as the wooden planks is used, and the cushion block is provided with connecting through holes;

[0015] The track can be connected to the plug-type sleeve through bolts via the connecting through holes and arranged on the cushion block;

[0016] The wooden plank can be connected to the plug-type sleeve through bolts.

[0017] In some embodiments, the track is a segmented connection type track.

[0018] In some embodiments, hook rings are arranged at both ends of the trolley for pulling the trolley to move through the hook rings.

[0019] In some embodiments, a limiting measure is arranged at the end of the track to prevent the trolley from running out of the track.

[0020] In some embodiments, a buffer device is arranged at the end of the trolley for providing buffering when hitting the limiting measure.

[0021] In some embodiments, the limiting measure is detachable.

[0022] In some embodiments, the preset load tonnage is 10 tons.

[0023] In the above embodiments of the present invention, it has been successfully realized that equipment with a weight of less than 5T can be freely transported in a one-piece cover form above the moon pool with a width close to 1 / 2 of the ship's width, breaking the traditional way of transporting only within 1T and in the form of a handcart through a traditional passage. There is no need to additionally occupy the ship width space to set up a passage, ensuring the room area on both sides of the main deck. The effective ship cabin space is utilized more efficiently. The diversity of equipment that can be placed in the moon pool is increased, and the possibility of transporting an ROV with a weight of about 4T to the moon pool for placement by a trolley is realized for the first time.

[0036] The following will specifically describe the transfer channel of the ultra-wide moonpool according to the embodiments of the present invention in conjunction with the accompanying drawings. Figures 1 to 8 The transfer channel of the ultra-wide moonpool according to the embodiments of the present invention will be specifically described.

[0037] The embodiments of the present invention provide a transfer channel for an ultra-wide moonpool. As Figures 1 to 3 shown, the transfer channel of the ultra-wide moonpool includes: a moonpool hatch cover 10, a track 20, and a trolley 30.

[0038] The moonpool hatch cover 10 is provided with a vertical and horizontal frame structure 11 on the bottom surface according to a preset load-bearing tonnage, and the moonpool hatch cover 10 serves as the carrier of the transfer channel.

[0039] In some embodiments, the preset load-bearing tonnage is 10 tons.

[0040] In an embodiment of the present invention, the structure of the moonpool top cover is designed with a vertical and horizontal frame structure according to a 10T load-bearing force, serving as the carrier of the transfer channel for the ultra-wide moonpool.

[0041] As Figure 4 and Figure 5 shown, the top surface of the moonpool hatch cover 10 and the main deck 80 adjacent to the moonpool hatch cover 10 are provided with groove positions 12 corresponding to the track 20, and a plug-type sleeve with internal threads is buried in the groove positions 12.

[0042] The plug-type sleeve can be made of stainless steel. In some embodiments, the weld at the connection between the plug-type sleeve and the cover plate is polished smoothly so that it does not leak during the flushing test.

[0043] The track 20 is arranged on the main deck and the moonpool hatch cover 10, and is detachably connected to the plug-type sleeve by bolts.

[0044] A long track (segmentally connected) is arranged on the floor of the compartment where the moonpool is located, close to the compartment wall panel, so that any equipment stored in any position in the compartment can be transported through the transfer channel of the moonpool top cover. The track is connected to the backing plate by bolts.

[0045] The trolley 30 is arranged on the track 20. The trolley 30 can move along the extension direction of the track 20 on the track 20 through the pulley 31 at the bottom of the trolley 30. The equipment 40 can be transported over the moonpool 90 through the trolley 30 via the track 20, and the total weight of the equipment 40 and the trolley 30 is less than or equal to the preset load-bearing tonnage. The trolley 30 can move freely back and forth on the track 20.

[0046] In some embodiments, the weight of the trolley 30 is less than or equal to 5 tons. Correspondingly, the total weight of the equipment 40 is less than or equal to 5 tons.

[0047] In some embodiments, for a ship whose main deck 80 where the moonpool compartment is located is not covered with wooden planks, when the track 20 is not installed, a plug matching the plug-type sleeve is used to plug it.

[0048] In some embodiments, the surface of the plug is flush with the main deck 80, and the top of the plug has a cross-grooved recess for fastening or disassembling operations.

[0049] In some embodiments, for a ship with a wooden plank laid on the main deck 80 where the moon-holding cabin is located, a spacer 13 with the same height as the wooden plank is adopted, and the spacer 13 is provided with connecting through holes.

[0050] The track 20 can be connected to the plug-type sleeve through bolts via the connecting through holes and is arranged on the spacer 13.

[0051] The wooden plank can be connected to the plug-type sleeve through bolts.

[0052] Usually, only the spacer 13 is directly connected to the embedded groove sleeve through bolts. The track is only installed on the spacer 13 during use, and the detachable type is flexible to use. The wooden plank is also connected to the groove sleeve embedded in the top cover through bolts. When the track is not used, the floor of the cabin can be kept flat and beautiful.

[0053] In some embodiments, the track 20 is a segmented connected track 20.

[0054] In some embodiments, hook rings 32 are provided at both ends of the trolley 30 for pulling the trolley 30 to move through the hook rings. For example, when in use, a portable winch is used to hook the hook rings 32 for translation.

[0055] In some embodiments, as Figure 1 shown, a limiting measure 21 is provided at the end of the track 20 for preventing the trolley 30 from running out of the track 20. The limiting measure 21 is detachably arranged, and its structure is as Figure 6 shown.

[0056] In some embodiments, a buffer device 33 is provided at the end of the trolley 30 for providing buffering when hitting the limiting measure 21.

[0057] As Figure 7 and Figure 8 shown, the track 20 can adopt an I-shaped steel rail. As Figure 2 and Figure 8 shown, in some embodiments, at least one side of the top of the steel rail of the track 20 extends laterally beyond the bottom for cooperating with the pulley 31 of the limiting trolley 20. The pulley 31 is a pair of side wheels arranged in pairs, and the two side wheels can respectively roll along the grooves on both sides of the I-shaped steel rail to realize the sliding of the trolley 20.

[0058] In the above embodiments of the present invention, the free transportation of equipment with a weight within 5T by means of an integrated cover plate above the moon pool with a width close to 1 / 2 of the ship's width is successfully realized, breaking the traditional way that the passage can only transport equipment within 1T and uses a trolley for transportation. There is no need to additionally occupy the ship's width space to set up a passage, ensuring the room area on both sides of the main deck. The effective ship's cabin space is utilized more efficiently. The diversity of equipment that can be placed in the moon pool is increased, and the possibility of transporting an ROV with a weight of about 4T to the moon pool for placement by a trolley is realized for the first time.
