Description

Technical Field

[0001] This invention belongs to the field of marine engineering equipment transportation technology, and specifically relates to a high-window adaptive offshore booster station land-water transshipment device and method. Background Technology

[0002] With the increasing global population, resource scarcity, and environmental degradation, human exploitation of marine wind power resources is accelerating, providing a continuous source of energy for the development of new energy sources using offshore wind power equipment. These large-volume, heavy offshore substations and other equipment, manufactured on land, need to be transported to the ocean for installation, inevitably involving a transfer process from land to sea. Common operational methods include gravity launching, floating launching, and mechanical launching. Among these, slide-towing launching is widely implemented, but its implementation is significantly limited by natural factors such as tides and weather. Operations cannot be carried out in bad weather and must be conducted within the permissible tidal range during appropriate tidal periods, requiring advance planning and coordination with various stakeholders, including dock operators.

[0003] Within the limited window of opportunity for transshipment operations, all transshipment work must be completed as quickly as possible; otherwise, any delay will require canceled operations to be rescheduled. Transshipment operations are also unsuitable during periods that meet tidal requirements but are experiencing short-term inclement weather. If unforeseen circumstances cause delays during transshipment, there is a high probability that the remaining time will be insufficient, forcing cancellation and rescheduling.

[0004] Currently, the industry generally adopts a method of improving transshipment efficiency by optimizing the loading strategy of large barges through computer-aided calculations during tidal permit windows to shorten the implementation period. Yoo Young-hye et al. also proposed in patent KR2020040037449 that placing barges on constructed offshore structures can help move large structures with high loads, such as ships, to the sea via barges; however, many locations lack the conditions or permits to construct this type of structure. Yu Hao et al. proposed a catamaran for marine engineering in patent CN200920247103.2, which can assist in the transshipment of offshore equipment, but this solution is inconvenient for transshipment work from land to water.

[0005] The current common transshipment methods need to determine the permissible transshipment time and duration based on the water level difference caused by tides in different geographical areas and at different times; therefore, the existing transshipment devices and methods still need to be improved. Summary of the Invention

[0006] Purpose of the Invention: To overcome the above shortcomings, the purpose of this invention is to provide a highly adaptive land-water transshipment device for offshore substations. Utilizing an innovative combination of multifunctional components such as mechanical, electrical, hydraulic, sensor, and controller components, a highly adaptive land-water transshipment device and method for offshore substations is designed. This involves a two-channel, dual-track coupled adjustment of a pre-set ballast strategy for the barge body and a multi-point, same-surface integrated elevation adjustment strategy for the land-water transshipment device. This enables offshore substations and other equipment to perform stepless, continuous, adaptive adjustment for transshipment over a longer time window. To facilitate land-water transshipment for ultra-large volume and ultra-heavy offshore engineering equipment platforms such as offshore substations, this invention reduces the limitations of the transshipment window caused by tides, effectively extends the effective transshipment working time, reduces the possibility of forced temporary rescheduling due to insufficient remaining time caused by weather or other unforeseen factors, and improves the utilization efficiency of transshipment terminals.

[0017] Furthermore, the transverse center distance and width of the elevation adjustment equipment compartment at the transshipment terminal and the elevation adjustment equipment compartment on the ship are equal, and the longitudinal length of the elevation adjustment equipment compartment at the transshipment terminal is less than the longitudinal length of the land transshipment platform, but greater than the longitudinal length of the maximum offshore booster station requiring transshipment.

[0018] The longitudinal length of the ship's elevation adjustment equipment compartment is less than the longitudinal length of the ship's transshipment platform, but greater than the longitudinal length of the maximum offshore booster station requiring transshipment.

[0019] The land-based transshipment platform and its guide rails have the same cross-section as the ship-based transshipment platform and its guide rails, except at the docking hinge. The width of one side of the transshipment dock elevation adjustment equipment compartment and the ship-based elevation adjustment equipment compartment is smaller than the width of one side of the land-based and ship-based transshipment platforms. The depth is not less than the sum of the total length of the hydraulic jack in its initial state and the installation height of the jack support base, the box-type slider, and the box-type slider guide rail.

[0020] In the shipboard elevation adjustment system of the present invention, several elevation adjustment devices are symmetrically installed in two horizontal rows on both sides of the shipboard elevation adjustment equipment compartment at the horizontal symmetry plane, with the same number and equal spacing in the longitudinal direction; when the elevation adjustment devices are in the initial state, the shipboard transshipment platform and the shipboard transshipment platform guide rail are laid flat on the barge deck, and the center of gravity of the land-water transshipment and transfer device can be aligned with the center of gravity of the transshipment vessel at maximum load in the horizontal and longitudinal directions, and the line connecting the two centers of gravity is perpendicular to the barge deck and the shipboard transshipment platform;

[0021] A number of elevation adjustment devices in the land elevation adjustment system are symmetrically installed in two rows on the transverse symmetry plane of the elevation adjustment equipment compartment on both sides of the transshipment terminal, with the same number and equal spacing in the longitudinal direction; when the elevation adjustment devices are in the initial state, the land transshipment platform and the land transshipment platform guide rail are at the minimum elevation and are laid flat on the ground of the transshipment terminal.

[0022] The method for determining the longitudinal installation spacing and quantity of the elevation adjustment devices for the land-based transshipment platform and the land-to-water transshipment receiving device described in this invention is as follows:

[0054] As can be seen from the above technical solution, the present invention has the following beneficial effects:

[0055] 1. The present invention discloses a high-window adaptive offshore substation land-water transshipment device. Utilizing an innovative combination of multifunctional components such as mechanical, electrical, hydraulic, sensor, and controller components, a high-window adaptive offshore substation land-water transshipment device and method are designed. This involves a two-channel, dual-track coupled adjustment of a pre-set ballast strategy for the barge body and a multi-point, same-plane integrated elevation adjustment strategy for the land-water transshipment device. This enables offshore substations and other equipment to perform stepless, continuous, adaptive adjustment for transshipment over a relatively long window period. To facilitate land-water transshipment of ultra-large volume and ultra-heavy offshore engineering equipment platforms such as offshore substations, this invention reduces the limitation of transshipment windows due to tides, effectively extends the effective transshipment working time, reduces the possibility of forced temporary rescheduling due to insufficient remaining time caused by weather or other unforeseen factors, and improves the utilization efficiency of transshipment terminals.

[0056] 2. The land-based elevation adjustment system and the ship-based elevation adjustment system described in this invention allow for elevation and angle adjustments as needed, effectively reducing the limitations of transshipment height differences caused by tidal factors. This adaptively keeps the transshipment height between land vessels within the permissible transshipment working range, effectively extending the permitted transshipment and loading time.

[0057] 3. The high-window adaptive offshore booster station land-water transshipment device and method described in this invention can actively and adaptively adjust the transshipment height between land vessels, extend the permissible working time window, facilitate the selection of more permissible transshipment time nodes and reduce the possibility of rescheduling due to temporary delays. It effectively solves the problems of the current transshipment method having a short permissible transshipment time, being unsuitable for transshipment operations even when tidal factors are met but short-term weather is unfavorable, and having to cancel or reschedule operations due to insufficient remaining time if unforeseen factors cause delays during the transshipment process.

[0058] 4. Based on the current industry practice of using a barge to adaptively adjust the deck and guide rail angles according to a pre-defined ballast strategy within a short transshipment period with a small tidal range, this invention provides a land-water transshipment device installed on a structurally modified barge. This device enables two-channel, dual-rail coupling adjustment of the barge's pre-defined ballast strategy and the land-water transshipment device's multi-point, same-surface, stepless, continuous adjustment strategy. Ultimately, it achieves stepless, continuous, and adaptive adjustment of the entire land-water transshipment operation, allowing for more precise and flexible transshipment operations.

[0059] 5. This method supplements the multi-point, integrated, stepless, continuous, and adaptive adjustment method of land-water transshipment and transfer devices, reducing the reliance on the pre-set ballast method of the barge body currently commonly used in the industry. In emergency situations, it provides more feasible options to continue the transshipment operation.

[0060] 6. The selection of permitted transshipment time points and duration range has been increased, providing more management and flow leeway for transshipment terminal work arrangements and improving the utilization efficiency of transshipment terminals. Attached Figure Description

[0115] This embodiment describes a high-window adaptive offshore booster station land-water transfer device and method. The lifting guide device 238 includes a guide bracket 2381, a spindle-shaped rotating shaft 2382, a rotating shaft slider 2383, and a damper 2384. The guide bracket 2381 has an elongated oval hole in the middle, square holes at both ends of the elongated oval hole, and square sliding grooves at both ends of the square holes on both sides. The diameter of the elongated oval hole is slightly larger than the outer diameter of the hydraulic cylinder, and the width of the square holes is smaller than the outer diameter of the hydraulic cylinder. During installation, the guide bracket 2381 is fitted with the hydraulic cylinder and spans the limiting grooves at both ends of the upper side of the elevation adjustment equipment compartment. The two ends of the spindle-shaped rotating shaft 2382 are fitted with bearings and mounted on the rotating shaft slider 2383. The rotating shaft slider 2383 is installed in the square hole groove.

[0116] The shipboard transshipment platform has no angle adjustment; that is, when the elevation adjustment device is vertically lifted, the damper of the jack guide device is in the initial pre-tightened state, and the outer circles of the two spindle-shaped rotating shafts of the same jack guide device are close to the hydraulic cylinder. This provides support and directional guidance for the elevation adjustment device during operation, preventing it from tilting laterally or longitudinally, and allowing for longitudinal swaying within a certain range under the constraint of the damper. Simultaneously, the spindle-shaped rotating shafts convert the sliding friction between the hydraulic elevation adjustment device and the guide device into rolling friction, thereby reducing lifting resistance.

[0117] This embodiment describes a high-window adaptive offshore substation land-water transshipment device and method. It employs a pre-set ballast strategy for the hull and a multi-point, same-plane integrated lifting dual-rail coupled adjustment to achieve continuous adaptive adjustment of the offshore substation transshipment operation. The transshipment strategy is as follows:

[0118] Step S121: According to the planned time, drive the hydraulic trolley to carry the offshore booster station along the guide rail 22 of the land transfer platform to the land transfer platform 21 at the minimum elevation position of the transfer dock 1 to wait for transfer;

[0119] Step S122: Using barge ballast calculation auxiliary software and combining the tide table, calculate the water load required for each ballast tank 33 of the barge when the front wheels of the first row of hydraulic trolleys carrying the offshore booster station begin to enter the ship's transshipment platform 41 and enter the positions of several nodes (such as 1 / 8, 1 / 4, 3 / 8, 1 / 2, 5 / 8, 3 / 4, etc.) of the longitudinal length of the ship's transshipment platform 41, while keeping the barge deck 32 and the land transshipment platform 21 approximately horizontal within the permissible angle range;

[0120] Step S123: According to the planned time, start the barge control system, read the signals of pressure sensor 237 and tilt sensor 44 respectively, empty the ballast water in each ballast tank 33 of the barge, and control the elevation adjustment device of the transfer and loading device to lift the transfer platform 41 on the barge to the high position with low hydraulic drive.

[0121] Step S124: During the rising tide, when the water level rises to the low point of the permissible working range of the tidal range, and the guide rail 42 of the ship transfer platform is at the same height as the guide rail 22 of the land transfer platform, the hydraulic trolley is controlled to start transferring the offshore booster station to the ship transfer platform 41.

[0122] Step S125: According to the previously established plan, when the hydraulic trolley carrying the offshore booster station arrives at the corresponding node positions in sequence, the ballast tank 33 of the barge is controlled to suck and discharge the corresponding amount of ballast water, so that the reading of the tilt sensor 44 on the barge deck reaches the planned number.

[0123] Step S126: The first hydraulic trolley carrying the offshore booster station moves onto the land-water transfer rail 22 to begin applying ballast to the transfer vessel 3. The control room 5 continuously adjusts the working hydraulic pressure of the hydraulic jacks 222 at the corresponding positions according to the feedback from the pressure sensors 237 at various locations, so that the support force provided is equal to the pressure value of the corresponding pressure sensor 237, in order to ensure that the transfer platform 41 on the ship provides sufficient support force.

[0124] Step S127: During the stage where part of the pressure from the offshore booster station is transferred to the transshipment vessel 3, tidal changes cause an increase in the overall elevation of the transshipment vessel 3. The elevation adjustment operation of the onshore elevation adjustment device is then initiated, working in conjunction with step S126 based on step S125, to jointly ensure the relative inclination angle between the onshore transshipment platform 21 and the transshipment platform 41 on board. Within a reasonable range;

[0125] Step S128: From the moment the overall pressure of the offshore booster station is transferred to the transshipment vessel 3 until the offshore booster station is transported to the designated location, based on step S125, the elevation adjustment system on the vessel is controlled to adaptively adjust the angle, reducing the pressure while keeping the transshipment platform 41 on the vessel level. To a reasonable range;

[0126] Step S129: After the entire offshore booster station is transported to the designated location, based on step S125, the hydraulic pressure of the ship's elevation adjustment equipment is reduced to control the ship's transfer platform 41 to slowly and smoothly descend onto the barge deck 32, and the offshore booster station is reinforced.

[0127] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
