Description

Technical Field

[0001] The present invention belongs to the technical field of marine construction, and particularly relates to an SPMT ship loading and transportation method for a floating installation module. Background Art

[0002] After the construction of the floating installation module in the slipway area is completed, it is usually necessary to use steel strands to perform towing operations on the slipway to complete the ship loading and transportation operations of the module.

[0003] The prior art has the following problems:

[0004] 1. The resources of the slipway area in the site are limited, and the floating installation module can only be assembled and constructed in the slipway area. During the peak period of the project, it is easy to cause a tense situation of site resources and cannot meet the synchronous construction of multiple projects.

[0005] 2. The preliminary preparation work for the slipway layout is relatively complex, consuming a large amount of manpower and material resources. It is necessary to purchase auxiliary materials such as Teflon plates, steel strands, wax oil, and asphalt paint, and at the same time prefabricate steel tools such as limit angle steels and stiffening rib plates. The procurement investment and labor costs are extremely high.

[0006] 3. The ship loading and transportation operation takes a long time, and the towing speed is only 25 meters per hour. The towing operation on the slipway alone needs to continue for more than ten hours, and it also causes great trouble to the subsequent load adjustment operation. The entire process also requires a large amount of equipment resources and the cooperation of multiple people for construction operations, and the equipment and labor costs are very high.

[0007] Therefore, it is urgent to design an SPMT ship loading and transportation method for a floating installation module to solve the problems of high installation cost, low efficiency, and site congestion existing in the ship loading and transportation of the floating installation module in the prior art mentioned above. Summary of the Invention

[0008] In order to solve the technical problems of high installation cost, low efficiency, and site congestion existing in the ship loading and transportation of the floating installation module in the prior art mentioned in the background art, an SPMT ship loading and transportation method for a floating installation module is provided to solve the above problems.

[0009] To achieve the above object, the specific technical solution of the SPMT ship loading and transportation method for a floating installation module of the present invention is as follows:

[0010] An SPMT ship loading and transportation method for a floating installation module includes the following steps:

[0011] S1. Prepare in advance the layout of the trestle, the positioning layout and welding of the marine supports, and the laying of the vehicle sleepers;

[0012] S2. Lower the height of the SPMT transporter to ensure there is a gap between the SPMT transporter and the lower surface of the transport lifting beam. According to the marked vehicle entry position on the transport lifting beam, drive the SPMT transporter under the floating installation module.

[0013] S3. Raise each column of the SPMT transporter separately using the corresponding hydraulic support system until the lower surface of the SPMT transporter contacts the transport lifting beam, and then connect all columns of the SPMT transporter together to form a hydraulic support system.

[0014] S4. Raise the height of the SPMT transporter, monitor the pressure gauge and check the contact point gap. The hydraulic system is pressurized until the floating installation module is lifted and completely separated from the general assembly cushion pier, and use chains and tighteners to complete the vehicle securing operation.

[0015] S5. Transport the floating installation module along the pre-designed transport route to the quay front. Monitor the operation status of the SPMT transporter throughout the process. After ensuring that the ship's ballasting capacity meets the requirements for the SPMT transporter to board the ship, the SPMT transporter advances towards the barge's positioning location through the connecting trestle.

[0016] S6. When the SPMT transporter reaches the position above the marine support pier, through fine-tuning and inspection, ensure that all columns of the SPMT transporter are in the designated positions.

[0017] S7. Operate the SPMT transporter to lower its height, and the height of the floating installation module will also decrease and contact the marine support pier until all the weight is completely transferred to the marine support pier. Disconnect the connection between all SPMT transporters, drive the SPMT transporters away from under the floating installation module in sequence, and the SPMT transporter returns to the quay through the connecting trestle to complete the operation of loading the floating installation module onto the ship.

[0018] Furthermore, in S1, according to the ship loading and transportation path of the SPMT transporter and the mooring position of the barge at the quay, complete the preparation work for the layout of the trestle in advance.

[0019] Furthermore, in S1, according to the final positioning position of the floating installation module on the barge after it is in place, complete the positioning layout and welding preparation work of the marine support pier in advance.

[0020] Furthermore, in S1, according to the vehicle layout position of the SPMT transporter for loading and transporting the floating installation module onto the ship, determine the contact position between the SPMT transporter and the transport lifting beam, and complete the preparation work for laying the vehicle sleepers in advance.

[0021] Furthermore, in S2, lower the height of the SPMT transporter to ensure there is a 100 - mm gap between the SPMT transporter and the lower surface of the transport lifting beam.

[0022] Furthermore, before the SPMT transporter enters the vehicle, it determines the fixation of the bulk members and measures the levelness of the lower surfaces of each transport lifting beam.

[0023] Furthermore, before the SPMT transporter transports, it checks the obstacles on the transportation route from the general assembly area to the ship loading area, making the cross-slope of the road surface not more than 2%, and the ground bearing capacity greater than 15 t / m².

[0024] Furthermore, the connection between the trestle and the barge deck is in the form of spot welding, and the length of the spot welding is not less than 50 mm and the interval is 500 mm.

[0025] Furthermore, the placement of the marine support pier should ensure an error of not more than ±20 mm in the length direction.

[0026] Furthermore, during the transportation of the SPMT transporter to the barge, the SPMT transporter is higher than the elevation of the barge deck, and the height difference between the SPMT transporter and the barge is within the range of 0 - 100 mm.

[0027] The SPMT ship loading and transportation method for the floating installation module of the present invention has the following advantages:

[0028] It only takes 2 hours to complete the positioning of the floating installation module from the dock front to the barge deck through the SPMT transporter, greatly reducing the ship loading operation period, significantly improving the work efficiency, effectively reducing the input of tools and manpower, greatly reducing the workload of the slideway laying preparation, saving the purchase cost of expensive Teflon plates and disposable consumables such as steel strands, wax oil, and asphalt paint, and not requiring materials such as limit angle steels and stiffening rib plates, greatly reducing the cost.

[0029] The floating installation module can be assembled and constructed in the non-slideway area, greatly expanding the construction application range of the non-slideway area of the site and effectively alleviating the pressure of the shortage of site resources in the slideway area during the peak period of the project.

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0040] Those skilled in the art can understand that although some of the embodiments herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0041] Next, refer to Att Figure 1 to Att Figure 7 Describe the SPMT ship loading and transportation method of the floating installation module of the present invention.

[0042] As Figures 1 to 7 shown, the SPMT ship loading and transportation method of the floating installation module 10 in the present invention includes the following steps:

[0043] S1. Pre-completed the layout of the trestle 2, the positioning layout and welding of the marine support pier 5, and the laying preparation work of the vehicle sleepers 9;

[0044] S2. Lower the height of the SPMT transporter 7 to ensure there is a gap between the lower surfaces of the SPMT transporter 7 and the transport lifting beam 8. According to the marked vehicle entry position on the transport lifting beam 8, drive the SPMT transporter 7 under the floating installation module 10;

[0045] S3. Independently raise each column of SPMT transporters 7 using the corresponding hydraulic support system until the lower surfaces of the SPMT transporters 7 and the transport lifting beam 8 come into contact, and then connect all columns of SPMT transporters 7 together to form a hydraulic support system;

[0046] S4. Raise the height of the SPMT transporters 7, monitor the pressure gauge and check the contact point clearance. The hydraulic system is pressurized until the floating installation module 10 is lifted and completely separated from the general assembly cushion pier 6, and use the chain 11 and the cable tightener 12 to complete the vehicle securing operation;

[0047] S5. The floating installation module 10 is transported along the pre-designed transport route to the quay front 1. Monitor the running status of the SPMT transporters 7 throughout the process. After ensuring that the ship's load adjustment capacity meets the loading requirements of the SPMT transporters 7, the SPMT transporters 7 advance towards the positioning location of the barge 4 through the connecting trestle 2; the SPMT transporters 7 advance to the boarding area 3; the barge 4 is connected to the quay front 1 through the mooring bollard 13.

[0048] S6. When the SPMT transporters 7 reach the position above the marine support pier 5, through fine adjustment and inspection, ensure that all columns of SPMT transporters 7 are in the designated positions;

[0049] S7. Operate the SPMT transporters 7 to lower the height, and the height of the floating installation module 10 will also decrease and come into contact with the marine support pier 5 until all the weight is completely transferred to the marine support pier 5. Disconnect the connection between all SPMT transporters 7, and drive the SPMT transporters 7 away from under the floating installation module 10 in sequence. The SPMT transporters 7 return to the quay through the connecting trestle 2 to complete the loading operation of the floating installation module 10.

[0050] Transporting the floating installation module 10 from the quay front 1 to the deck of the barge 4 by the SPMT transporters 7 only takes 2 hours, greatly reducing the loading operation period, significantly improving the work efficiency. At the same time, it effectively reduces the input of tools and manpower, greatly reduces the workload of preparing the slipway laying, saves the purchase cost of expensive Teflon plates and disposable consumables such as steel strands, wax oil, and asphalt paint, and does not require materials such as limit angle steel and stiffening ribs, greatly reducing the cost.

[0051] Moreover, the floating installation module 10 can be assembled and constructed in the non-slipway area, greatly expanding the construction application scope of the non-slipway area of the site and effectively alleviating the pressure of the shortage of site resources in the slipway area during the peak period of the project.

[0052] Furthermore, as Figures 1 to 3As shown in the figure, in S1, according to the ship loading and transportation path of the SPMT transporter 7 and the mooring position of the barge 4 at the dock, the layout preparation work of the trestle 2 is completed in advance; according to the final in-place position of the floating installation module 10 on the barge 4 after it is in place, the positioning layout and welding preparation work of the marine pier 5 are completed in advance; according to the vehicle layout position of the SPMT transporter 7 for transporting the floating installation module 10, the contact position between the SPMT transporter 7 and the transport lifting beam 8 is determined, and the laying preparation work of the vehicle body sleepers 9 is completed in advance. Before transporting the floating installation module 10, the layout of the trestle 2, the positioning layout and welding of the marine pier 5, and the laying preparation work of the vehicle body sleepers 9 are completed in advance.

[0053] Further, as Figure 3 and Figure 4 shown, in S2, the height of the SPMT transporter 7 is lowered to ensure that there is a 100 mm gap between the lower surfaces of the SPMT transporter 7 and the transport lifting beam 8. In this embodiment, there is a gap of about 100 mm between the lower surfaces of the SPMT transporter 7 and the transport lifting beam 8 to avoid interference between the lower surfaces of the SPMT transporter 7 and the transport lifting beam 8.

[0054] Further, as Figure 4 shown, before the SPMT transporter 7 enters the vehicle, it is necessary to determine whether the fixation of the bulk members is completed, measure the levelness of the lower surfaces of each transport lifting beam 8, and identify the risk of collision between the SPMT transporter 7 and the structural members and the general assembly pier 6.

[0055] Further, before the SPMT transporter 7 transports, check the obstacles on the transport route from the general assembly area to the ship loading area, including any sharp objects that may damage the tires, cover the steel plates on individual uneven road sections, so that the slope of the road surface in all directions is not greater than 2%, and the ground bearing capacity is greater than 15 t / m2.

[0056] Further, as Figure 6 and Figure 7 shown, during the preparation process of the ship loading operation, the trestle 2 and the deck of the barge 4 are connected by spot welding, and the length of the spot welding is not less than 50 mm and the interval is 500 mm. The placement of the marine pier 5 should ensure an error of not more than ±20 mm in the length direction.

[0057] Further, during the process of the SPMT transporter 7 transporting the floating installation module 10, it is necessary to ensure that the dynamic load adjustment of the ship meets the operation requirements, always ensure that the ship deck is higher than the dock elevation, and the height difference must be controlled between 0 and 100 mm.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
