Description

Technical Field

[0001] This invention relates to the field of engineering construction, and in particular to a construction process for lateral towing and positioning of DSF (Dual Surface Floating) modules without a sliding track. Background Technology

[0002] In the fields of marine engineering and large modular engineering construction, the construction and placement processes of floating modules (such as offshore platform modules) and floating support units (DSFs) directly affect project efficiency, cost, and safety. In traditional processes, DSFs are typically constructed using a shared slipway with the modules and then placed in position by longitudinal towing. However, this method has the following limitations: Space resource constraints: Limited slide resources and parallel construction of modules and DSF can easily lead to site congestion. Especially when building large modules, longitudinal dragging requires the reservation of extra-long slide space, which imposes strict requirements on site length and is difficult to adapt to complex factory layouts.

[0003] Low construction efficiency: The shared use of the slideway leads to overlapping and interference of work processes. The construction of modules and DSF construction and towing operations need to be strictly staggered, which prolongs the overall construction period. In addition, the longitudinal towing path is long, and the debugging and safety monitoring of the traction system are highly complex.

[0004] Poor site adaptability: Traditional processes rely on the continuous layout of the slide. If there is uneven settlement, obstacles, or non-slide areas (such as hardened ground or temporary storage areas) on the site, it is difficult to flexibly adjust the construction plan, which may easily lead to structural deformation or safety risks.

[0005] Cost control is difficult: In order to meet the longitudinal dragging requirements, a large number of additional sliding blocks need to be laid, which increases material and construction costs; at the same time, process delays and site modification costs further increase project costs. Summary of the Invention

[0006] The purpose of this invention is to provide a construction process for the lateral towing and positioning of DSF (Dual Surface Support Float) modules without a sliding track, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a construction process for the lateral towing and positioning of DSF (Dual Float Module) without a sliding track, comprising the following steps: S1. Determine that the construction direction of the floating module is longitudinal, and clarify its longitudinal construction location; S2. Confirm that there is space next to the block to place the DSF, and at the same time determine the lateral position of the block on the slide. S3. Arrange the slides for building blocks and the slides for lateral dragging of DSF; S4. Complete the construction of the floating assembly on the slide; S5. Complete the construction of the DSF in the non-slide area; S6. Extend the slide for lateral dragging of DSF; S7. Arrange skis on the extended DSF transverse drag track; S8. Use a self-propelled modular transporter (SPMT) to transport the DSF onto the skid and fix the DSF to the skid; S9. Arrange a traction system for laterally towing the DSF, and use this traction system to laterally tow the DSF to the bottom of the module; S10. Use a jack to lift the DSF, remove the slip shoe, and then control the jack to lower the DSF to the designated position. S11. After the module has completed the weight transfer, connect the module to the DSF as a whole, and then wait for and complete the overall loading of the module onto the ship.

[0008] Preferably, in step S1, the longitudinal construction direction of the module is determined according to the overall project plan and the carrying capacity of the floating vessel, and this longitudinal direction is parallel to the slipway. During the construction phase, the supporting structure of the module rests entirely on the slipway to avoid the impact of uneven site settlement on the construction of the module.

[0009] Preferably, in step S2, the space is calculated and reserved based on the requirements of large-scale hoisting operations of the module and the subsequent towing distance of the DSF. Space is reserved on one side of the module for DSF transportation and space is reserved on the other side for the arrangement of the traction system. The lateral position of the module on the slide is determined based on the reserved space.

[0010] Preferably, in step S3, the slide is arranged in at least two stages according to the construction stage requirements: The first phase covers the construction area of ​​the slide block and the initial area of ​​DSF lateral dragging, and reserves the installation positions of the block support structure, DSF dragging channel and traction auxiliary structure. The second-stage slipway is the extended DSF lateral towing slipway in step S6, and a third-stage loading slipway can be added according to the subsequent module loading requirements.

[0011] Preferably, in step S4, the deck structure of the floating block adopts a spatial steel frame composed of beams, slabs, columns and diagonal braces. The main structure of the block adopts a prefabricated segmented assembly mode. According to the overall structural strength requirements, temporary supports are arranged at the prefabricated segment hoisting positions. The temporary supports are made of steel that meets the strength standards.

[0012] Preferably, in step S5, the construction location of the DSF avoids the block hoisting operation range, the DSF structure is a spatial steel frame composed of beams, slabs, columns and diagonal braces, and the construction direction is consistent with the subsequent towing and positioning direction; The construction site in the non-slide area needs to be equipped with a support foundation, the levelness of the foundation should be controlled and the measurement data should be recorded. During the construction process, the foundation settlement should be monitored. If the settlement exceeds the tolerance, the settlement impact should be controlled by adding supports or speeding up the forming of the DSF frame. The lifting and strengthening structure of the DSF and the strengthening structure required for subsequent transportation should be prefabricated on the DSF in advance.

[0013] Preferably, in step S7, the height of the sliding shoe is determined according to the height of the slide and the transport height of the DSF, and is used to support the DSF and reduce its frictional resistance when it is dragged on the slide. In step S8, the DSF is fixed to the self-propelled modular transport vehicle by connectors, and the transport height is controlled during the transport process to ensure that the DSF is accurately placed on the skis.

[0014] Preferably, in step S9, the traction system is configured based on the weight of the DSF and the towing resistance, and includes at least a winch and a pulley block. The anchor points of the traction system and the position of the winch are arranged to ensure that the wire rope is of sufficient length and does not collide with the slide or the block structure. Before towing, the relative elevation of the DSF and the floating point of the block is measured to ensure that the DSF can smoothly enter under the block. If the traction force is insufficient when towing is started, a booster device is used to assist. The final position of the DSF is marked and a limiting structure is set.

[0015] Preferably, in step S10, the number and specifications of the jacks are determined according to the weight of the DSF, and the lifting speed and synchronization are controlled during the lifting process; when the slipper is removed, the slipper is connected by the traction component and slowly moved out from under the DSF to ensure stable support of the DSF; before lowering the DSF, check that there are no debris under it, and control the depressurization speed of the jacks during the lowering process so that the DSF can fall smoothly to the designated position.

[0016] Preferably, in step S11, the weight transfer of the module is confirmed by weighing. After being connected to the DSF as a whole, if a third-stage loading slide is set up, the slide layout and the installation and commissioning of the loading traction equipment are completed. Finally, the module is loaded onto the ship as a whole by towing or other adaptable methods.

[0017] The technical effects and advantages of this invention are as follows: 1. The construction process of the floating module DSF using lateral towing in non-slipway construction avoids competition with the module for slipway resources by independently constructing the DSF in the non-slipway area, enabling parallel construction of the module and DSF and significantly shortening the overall construction period. At the same time, it reduces the dependence on slipway length, adapts to small and medium-sized site layouts, and breaks through the limitations of slipway resources. The lateral towing method only requires a limited lateral space to be reserved next to the module, which reduces the space occupation compared to the hundreds of meters of slipway required by traditional longitudinal towing, thus optimizing space utilization efficiency. When constructing the DSF in the non-slipway area, hardened ground and temporary supports can be used to replace the traditional slipway. Settlement monitoring and dynamic adjustments (such as adding temporary supports) can adapt to complex site conditions and reduce the stringent requirements for foundation flatness.

[0018] 2. The construction process of the DSF (Diverterless Superfabrication Unit) floating module, which uses a non-slipway construction method for lateral towing, reduces the number of slipway blocks required, saving materials and installation costs. Through limiting structures (such as gap control of 5-25mm), graded traction speeds, and jack-assisted design, the lateral towing process of the DSF is ensured to be smooth and controllable. Pre-fabricated reinforcing structures (such as jacking points and transport stiffeners) avoid the impact of later welding on structural strength. The modular process steps (such as phased slipway layout and segmented DSF prefabrication) allow for flexible adjustment of parameters (such as slipway height and traction equipment specifications) according to module size, weight, and site conditions, making it suitable for the construction and placement needs of floating modules of different tonnages.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides, for example Figure 1 - Figure 2 The construction process shown is a non-slipway construction method for DSF (Diverterless Superfabrication System) modules, which involves lateral towing and positioning. The process includes the following steps: S1. Determine that the construction direction of the floating module is longitudinal, and clarify its longitudinal construction location; S2. Confirm that there is space next to the block to place the DSF, and at the same time determine the lateral position of the block on the slide. S3. Arrange the slides for building blocks and the slides for lateral dragging of DSF; S4. Complete the construction of the floating module on the module construction slide; S5. Complete the construction of the DSF in the non-slide area; S6. Extend the slide for lateral dragging of DSF; S7. Arrange skis on the extended DSF transverse drag track; S8. Use a self-propelled modular transporter (SPMT) to transport the DSF onto the skis and secure the DSF to the skis; S9. Arrange a traction system for laterally towing the DSF, and use this traction system to laterally tow the DSF to the bottom of the module; S10. Use a jack to lift the DSF, remove the slip shoe, and then control the jack to lower the DSF to the designated position. S11. After the module has completed the weight transfer, connect the module to the DSF as a whole, and then wait for and complete the overall loading of the module onto the ship.

[0022] Furthermore, in step S1, the longitudinal construction direction of the module is determined according to the overall project plan and the carrying capacity of the floating vessel, and this longitudinal direction is parallel to the slipway. During the construction phase, the supporting structure of the module rests entirely on the slipway to avoid the impact of uneven site settlement on the construction of the module.

[0023] Furthermore, in step S2, based on the requirements of large-scale hoisting operations of the module and the subsequent towing distance of the DSF, space is calculated and reserved. Space is reserved on one side of the module for DSF transportation, and space is reserved on the other side for the arrangement of the traction system. The lateral position of the module on the slide is determined based on the reserved space.

[0024] Preferably, in step S3, the slide is arranged in at least two stages according to the construction stage requirements: The first phase covers the construction area of ​​the slide block and the initial area of ​​DSF lateral dragging, and reserves the installation positions of the block support structure, DSF dragging channel and traction auxiliary structure. The second-stage slipway is the extended DSF lateral towing slipway in step S6, and a third-stage loading slipway can be added according to the subsequent module loading requirements.

[0025] Furthermore, in step S4, the deck structure of the floating block adopts a spatial steel frame composed of beams, plates, columns and diagonal braces. The main structure of the block adopts a prefabricated segmented assembly mode. According to the overall structural strength requirements, temporary supports are arranged at the prefabricated segment hoisting positions. The temporary supports are made of steel that meets the strength standards.

[0026] Furthermore, in step S5, the construction location of the DSF avoids the block hoisting operation range. The DSF structure is a spatial steel frame composed of beams, slabs, columns and diagonal braces, and the construction direction is consistent with the subsequent towing and positioning direction. The construction site in the non-slide area needs to be equipped with a support foundation, the levelness of the foundation should be controlled and the measurement data should be recorded. During the construction process, the foundation settlement should be monitored. If the settlement exceeds the tolerance, the settlement impact should be controlled by adding supports or speeding up the forming of the DSF frame. The lifting and strengthening structure of the DSF and the strengthening structure required for subsequent transportation should be prefabricated on the DSF in advance.

[0027] Furthermore, in step S7, the height of the sliding shoe is determined based on the height of the slide and the transport height of the DSF, and is used to support the DSF and reduce its frictional resistance when it is dragged on the slide. In step S8, the DSF is fixed to the self-propelled modular transport vehicle by connectors, and the transport height is controlled during the transport process to ensure that the DSF is accurately placed on the skis.

[0028] Furthermore, in step S9, the traction system is configured based on the weight of the DSF and the towing resistance, including at least a winch and a pulley block. The anchor points of the traction system and the position of the winch are arranged to ensure that the wire rope is of sufficient length and does not collide with the slide or the block structure. Before towing, the relative elevation of the DSF and the floating point of the block is measured to ensure that the DSF can smoothly enter under the block. If the traction force is insufficient when towing is started, a booster device is used to assist. The final position of the DSF is marked and a limiting structure is set.

[0029] Furthermore, in step S10, the number and specifications of the jacks are determined according to the weight of the DSF, and the lifting speed and synchronization are controlled during the lifting process; when the slipper is removed, the slipper is connected by the traction component and slowly moved out from under the DSF to ensure stable support of the DSF; before lowering the DSF, check that there are no debris under it, and control the depressurization speed of the jacks during the lowering process so that the DSF can fall smoothly to the designated position.

[0030] Furthermore, in step S11, the weight transfer of the module is confirmed through weighing operations. After being connected to the DSF as a whole, if a third-stage loading slide is set up, the slide layout and the installation and commissioning of the loading traction equipment are completed. Finally, the module is loaded onto the ship as a whole by towing or other adaptation methods.

[0031] By constructing DSFs independently in non-slide areas, competition for slide resources with modules is avoided, allowing for parallel construction of modules and DSFs and significantly shortening the overall construction period. Simultaneously, it reduces reliance on slide length, adapts to small and medium-sized site layouts, and overcomes slide resource limitations. The lateral dragging placement method requires only limited lateral space beside the module, reducing space occupation compared to the hundreds of meters of slides required by traditional longitudinal dragging, thus optimizing space utilization efficiency. When constructing DSFs in non-slide areas, hardened ground and temporary supports can be used instead of traditional slides. Settlement monitoring and dynamic adjustments (such as adding temporary supports) can adapt to complex site conditions, reducing stringent requirements for foundation flatness.

[0032] The design reduces the number of slide blocks, saving materials and installation costs. By employing limiting structures (such as gap control of 5-25mm), graded traction speeds, and jack-assisted design, the lateral dragging process of the DSF is ensured to be smooth and controllable. Pre-fabricated reinforcing structures (such as jacking points and transport stiffeners) prevent the impact of later welding on structural strength. The modular process steps (such as phased slide block layout and segmented DSF prefabrication) allow for flexible adjustment of parameters (such as slide block height and traction equipment specifications) based on block size, weight, and site conditions, making it suitable for the construction and placement needs of float blocks of different tonnages.

[0073] 3. Drag control: Elevation check: Accurately measure the elevation of the DSF (including DSU), the elevation of the bottom plate of the module buoyancy point, and the height of each slide block in the traction path to ensure that the top elevation of the DSU is lower than the bottom elevation of the module buoyancy point with a margin.

[0082] 3. Preparation for loading: Slide layout: The third stage of the slide is arranged (three layers with a total of 204 slide blocks).

[0083] Equipment preparation: Complete the procedures such as loading and towing equipment, and finally wait for and complete the overall loading of the modules onto the ship.

[0084] As one implementation method, some embodiments attempt to address the competition for slide resources by constructing DSFs without slide tracks and laterally dragging them into place. However, the slide system still employs a phased, static layout (such as the three-stage slides mentioned above), which cannot adapt to dynamic changes during construction in real time, such as module hoisting adjustments or site anomalies. This static layout leads to low resource utilization, and the fixed path during DSF placement can easily cause accuracy deviations or collision risks.

[0085] To address this issue, this embodiment proposes an enhanced solution by introducing an "adaptive track system" and digital twin scheduling. This solution upgrades the static track to a modular adjustable track, with each track block integrating a hydraulic lifting mechanism (such as a servo motor), allowing for remote control of elevation adjustments (accuracy ±1mm). It also integrates with the digital twin platform to optimize the dragging path in real time based on BIM and IoT sensor data. This solution works in conjunction with steps S3, S6, and S9: during the track layout phase, the digital twin model pre-loads the construction plan; during track extension, the adaptive system fine-tunes the path based on the DSF position; and the traction system dynamically adjusts its speed upon receiving platform commands.

[0086] Furthermore, addressing the conflict between construction coordination and fragmented control logic—for example, the traction system's calculation based solely on DSF weight without considering real-time load or environmental factors, increasing safety risks—this embodiment integrates discrete control components through IoT and AI algorithms. Pressure sensors and laser rangefinders are deployed in the traction system and jacks, with data uploaded to edge computing nodes. AI predicts towing resistance based on historical data and dynamically adjusts the winch's output force. Simultaneously, the predictive traction model, combined with weather forecasts and structural stress data, identifies risks in advance and automatically activates the booster device. This network is seamlessly integrated with steps S8-S11: monitoring DSF attitude during SPMT transport; AI synchronously controls the winch during towing and positioning; and automatic synchronization of jack lifting is achieved through closed-loop control.

[0087] More specifically, when constructing the DSF in the non-slip zone (step S5), although a hardened ground surface is utilized, the supporting foundation relies on rigid cement blocks (3800 mm high in the example). Settlement monitoring is a passive response and cannot actively compensate for uneven settlement, which may lead to deformation or positioning errors of the DSF structure. This problem stems from the rigid design of the foundation system, which is difficult to adapt to complex conditions such as soft soil foundations.

[0088] Therefore, this embodiment upgrades the DSF support foundation to an intelligent unit. The cement block incorporates piezoelectric sensors and a fine-tuning hydraulic cushion (made of shape memory alloy) to monitor settlement data in real time and transmit it wirelessly to the control center. Machine learning algorithms predict settlement trends and automatically adjust the support height. This system works in conjunction with steps S5 and S10: it compensates for settlement in real time during the DSF construction phase; and it uses algorithms to pre-verify the elevation before placement to guide jack operation.

[0089] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
