Description

Technical Field

[0001] The present invention relates to the technical field of floating tourism platforms, and in particular to a mooring system suitable for large-scale floating tourism platforms. Background Art

[0002] As a new type of marine equipment, a floating tourism platform can serve as an important platform base for marine tourism, especially for nearshore and near-reef tourism. At the same time, it can be paired with large and medium-sized luxury cruise ships, as well as various yachts and underwater sightseeing submersibles, serving as an important support for China's coastal tourism economy and cruise line economy.

[0003] In the prior art, for the mooring system of a floating platform, it usually adopts a symmetric mooring layout (such as single-point mooring, multi-point mooring, etc.) based on a conventional rectangular configuration and an offshore deployment scenario to ensure the stability of the platform under the action of wind, waves and currents. However, considering requirements such as the tourist carrying capacity and the supporting of functional areas, the scale of the tourism platform is large; from the aesthetic point of view, its configuration is relatively special, not in the form of a traditional rectangular configuration; from the perspective of the actual operation and maintenance of the platform and the positioning of tourism economy, the platform deployed in nearshore and near-reef waters will have the best economy and practicability; in addition, it is required that the setting of the mooring system does not affect the realization of functions such as platform tourism, appearance aesthetics, and the berthing of cruise ships and yachts.

[0004] In summary, the traditional mooring system is difficult to be applicable to the application scenario of large-scale floating tourism platforms. There is an urgent need for a mooring system suitable for different types of large-scale floating tourism platforms, which can improve economy and applicability while ensuring the safety and functionality of the platform. Summary of the Invention

[0005] The applicant of the present invention aims at the above-mentioned shortcomings in the existing production technology and provides a mooring system suitable for large-scale floating tourism platforms with a reasonable structure, which can safely position a large-scale floating platform, effectively ensure the realization of the tourism function of the floating platform, and can improve economy and applicability while ensuring the safety and functionality of the platform.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A mooring system suitable for large-scale floating tourism platforms includes a floating platform. Several strands of mooring anchor chains are arranged at the bow and stern of the floating platform. Each single-strand mooring anchor chain includes an S1 section, an S2 section, an S3 section, and an S4 section connected in sequence. Among them, the S1 section is used to connect to an anchoring foundation, and the S4 section is used to connect to the floating platform;

[0008] By connecting the S1 sections of some or all strands of mooring anchor chains to the anchoring foundation fixed to the seabed, the floating platform is moored.

[0009] As a further improvement of the above technical solution:

[0010] The floating platform includes a main module and several auxiliary modules installed in cooperation with the main module;

[0011] Several main module windlasses for retracting and deploying corresponding mooring anchor chains are installed on the main module in cooperation;

[0012] Auxiliary module windlasses for retracting and deploying corresponding mooring anchor chains are respectively installed on two of the auxiliary modules, so that two mooring anchor chains are configured at the stern of the floating platform.

[0013] Five main module windlasses are configured on the main module, so that five mooring anchor chains are configured at the bow of the floating platform.

[0014] When the floating platform is in the survival state, the five mooring anchor chains configured at the bow of the floating platform are respectively connected to the corresponding anchoring bases to moor the floating platform.

[0015] When the floating platform is in the operating state, the five mooring anchor chains configured at the bow of the floating platform are respectively connected to the corresponding anchoring bases. At the same time, the two mooring anchor chains configured at the stern of the floating platform are respectively connected to the corresponding anchoring bases to moor the floating platform.

[0016] A main module anchor chain compartment is provided for each main module windlass.

[0017] Corresponding auxiliary module anchor chain compartments are provided on both of the two auxiliary modules equipped with auxiliary module windlasses.

[0018] A hydraulic station is installed in cooperation with one of the auxiliary modules.

[0019] A single mooring anchor chain uses parallel double chains.

[0020] The diameter of the S1 section of a single mooring anchor chain is 208 mm and it uses a studless anchor chain;

[0021] The diameter of the S2 section of a single mooring anchor chain is 120 mm and it uses a studless anchor chain;

[0022] The diameter of the S3 section of a single mooring anchor chain is 140 mm and it uses a polyester cable;

[0023] The diameter of the S4 section of a single mooring anchor chain is 130 mm and it uses an ultra-high molecular weight polyethylene cable.

[0024] The beneficial effects of the present invention are as follows:

[0025] The structure of the present invention is compact and reasonable, and it is convenient to operate. By adopting a mooring anchor chain with a segmented design, functional zoning can be achieved, reducing the risk of its failure and enhancing the mooring reliability. Thus, a reliable mooring solution is provided for large floating tourism platforms, realizing the unity of safety, economy and practicability, meeting the mooring requirements and aesthetic requirements of the floating platform, and achieving the functional requirements of the tourism platform under operating sea conditions.

[0026] The present invention also has the following advantages:

[0027] (1) In the present invention, the two mooring anchor chains on the two auxiliary modules adopt a cross-mooring method, which can improve the mooring capacity of the mooring anchor chain. Cooperating with the five mooring anchor chains arranged on the main module can meet the functional requirements of the floating platform under operating sea conditions, which is conducive to the berthing of large ocean liners and small and medium-sized yachts.

[0028] (2) In the present invention, mooring is carried out by relying on the five mooring anchor chains configured at the bow of the floating platform. Utilizing the weather vane effect, it can ensure the survival requirements of the floating platform under extreme sea conditions and can meet the mooring and positioning requirements under severe sea conditions such as typhoons.

[0029] (3) In the present invention, the floating platform 9 is restricted by seven mooring anchor chains together, so that the floating platform can meet the functional requirement that it should not generate large displacements under the action of environmental loads during the operating state, and can provide an environment and facilities for tourists' sea tourism and leisure activities.

[0030] (4) In the present invention, the single mooring anchor chain adopts a parallel double chain, which can provide a stronger mooring force, effectively resist external force impacts such as strong winds and rapid currents, and enhance the mooring stability.

[0031] (5) In the present invention, by setting the S1 section for connecting with the anchoring foundation, which has the largest diameter, its own weight can be increased to maintain a certain lying-on-bottom section, thereby preventing the mooring anchor chain 8 from being tightened and generating an upward pulling force on the anchoring foundation.

[0032] (6) In the present invention, by setting the S2 section, which adopts a studless anchor chain and has a smaller diameter, as a transition section of the S1 section, it ensures that the connection point of the S2 section and the S3 section is away from the seabed, thereby avoiding damage caused by friction between the S3 section and seawater.

[0033] (7) In the present invention, by setting the S3 section, which adopts a polyester cable, it can reduce the stiffness of the chain-cable combination and improve the overall buffering performance of the mooring anchor chain.

[0034] (8) In the present invention, by setting the S4 section, which adopts a high molecular polyethylene cable with high tensile strength, it is used to directly connect with the corresponding anchor winch.

[0035] (9) The switching operation between the single-point mooring mode and the three-point mooring mode in the present invention is convenient and fast, and can be completed by the equipment carried on the floating platform itself without the assistance of external working vessels, with good practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The following combines the drawings to illustrate the specific embodiments of the present invention.

[0043] The structure and function of the present invention are as follows:

[0044] As Figures 1 - 5 shown, a mooring system applicable to a large-scale floating tourism platform includes a floating platform 9. Both the bow and stern of the floating platform 9 are configured with several strands of mooring anchor chain 8. A single strand of mooring anchor chain 8 includes S1 segment, S2 segment, S3 segment, and S4 segment connected in sequence. Among them, the S1 segment is used to connect with the anchoring foundation, and the S4 segment is used to connect with the floating platform 9; by connecting the S1 segments of some or all strands of the mooring anchor chain 8 with the anchoring foundation fixed to the seabed, the floating platform 9 is moored. By arranging the mooring anchor chain 8 at the bow and stern of the floating platform 9 respectively, it is convenient to flexibly adjust the layout according to different sea conditions and improve the adaptability of the floating platform 9; at the same time, the mooring anchor chain 8 adopts the S1-S4 segment combined structure, which can reduce redundant configuration and lower material and maintenance costs.

[0045] The floating platform 9 includes a main module 1 and several auxiliary modules 2 installed in cooperation with the main module 1; several main module windlasses 3 for retrieving and releasing the corresponding mooring chains 8 are installed on the main module 1 in cooperation; on two of the auxiliary modules 2, auxiliary module windlasses 5 for retrieving and releasing the corresponding mooring chains 8 are respectively installed, so that two mooring chains 8 are configured at the stern of the floating platform 9; five main module windlasses 3 are configured on the main module 1, so that five mooring chains 8 are configured at the bow of the floating platform 9. As Figures 1 - 2 shown, the floating platform 9 of the present invention is a large-scale floating platform, which is formed by splicing and connecting the main module 1 and several auxiliary modules 2. The main module 1 and the auxiliary modules 2 have different shapes and can be spliced into floating platforms 9 of various shapes to meet the tourism function; as Figures 3 - 4 shown, both the main module 1 and the auxiliary modules 2 are of double-deck configuration, and the vertical space can be utilized for functional zoning. The forecastle deck is the tourist activity area, which is convenient for tourists to enjoy the sea view; the corresponding windlasses are arranged on the main deck for the working area. By carrying out functional zoning, the tourist experience can be improved and the personal safety of tourists can be guaranteed.

[0046] The main module windlasses 3 and the auxiliary module windlasses 5 are respectively used to retrieve and release the corresponding mooring chains 8, so as to complete the mooring of the floating platform 9; as Figure 1 、 Figure 5 shown, the five main module windlasses 3 are arranged in a row in the horizontal direction, and the two auxiliary module windlasses 5 ( Figure 1 only one auxiliary module 2 is shown) are symmetrically arranged along the center of the five main module windlasses 3, so that the seven mooring chains 8 are arranged in a three-point distribution; for the five mooring chains 8 on the main module 1, the distance between two adjacent mooring chains 8 is 2 meters. On the basis of meeting the safety and functional requirements of the floating platform 9, the overall shaping effect of the floating platform 9 is not affected, and it has strong engineering applicability; in addition, the two mooring chains 8 on the two auxiliary modules 2 adopt a cross-mooring method, which can improve the mooring capacity of the mooring chains 8, and cooperate with the five mooring chains 8 arranged on the main module 1 to meet the functional requirements of the floating platform 9 under the operating sea conditions.

[0047] When the floating platform 9 is in the survival state, the five mooring anchor chains 8 configured at the bow of the floating platform 9 are respectively connected to the corresponding anchoring bases, thereby mooring the floating platform 9; when the floating platform 9 is in the operating state, the five mooring anchor chains 8 configured at the bow of the floating platform 9 are respectively connected to the corresponding anchoring bases, and at the same time, the two mooring anchor chains 8 configured at the stern of the floating platform 9 are respectively connected to the corresponding anchoring bases, thereby mooring the floating platform 9. In the present invention, based on the seven mooring anchor chains 8, the floating platform 9 has two mooring modes: the single-point mooring mode and the three-point mooring mode. In the single-point mooring mode, it relies on the five mooring anchor chains 8 configured at the bow of the floating platform 9 for mooring. Utilizing the wind vane effect, it can ensure the survival requirements of the floating platform 9 under extreme sea conditions (such as typhoons); in the three-point mooring mode, it relies on the seven mooring anchor chains 8 to jointly restrain the floating platform 9, so that the floating platform 9 can meet the functional requirement of not generating large displacements under environmental loads during the operating state, and can provide an environment and facilities for tourists' offshore tourism and leisure activities.

[0048] A single main module windlass 3 is provided with a main module anchor chain compartment 4; corresponding auxiliary module anchor chain compartments 6 are provided on both of the two auxiliary modules 2 configured with auxiliary module windlasses 5. The main module anchor chain compartment 4 and the auxiliary module anchor chain compartments 6 are used for storing the corresponding mooring anchor chains 8, thereby keeping the deck position of the floating platform 9 clean.

[0049] A hydraulic station 7 is installed on one of the auxiliary modules 2 in a mating manner. The hydraulic station 7 is used to supply hydraulic oil to the main module windlass 3 and the auxiliary module windlasses 5.

[0050] A single mooring anchor chain 8 adopts a parallel double chain, which can provide stronger mooring force, effectively resist external forces such as strong winds and rapid currents, and enhance the mooring stability.

[0051] The diameter of the S1 section of the single mooring anchor chain 8 is 208 mm, and it adopts a studless anchor chain; the diameter of the S2 section of the single mooring anchor chain 8 is 120 mm, and it adopts a studless anchor chain; the diameter of the S3 section of the single mooring anchor chain 8 is 140 mm, and it adopts a polyester cable; the diameter of the S4 section of the single mooring anchor chain 8 is 130 mm, and it adopts a ultra-high molecular weight polyethylene cable. By dividing the mooring anchor chain 8 into S1 - S4 sections with different diameters and materials, segmented function enhancement can be carried out, the reliability of the mooring system can be improved as a whole, and the cost can be reduced.

[0052] The parameters of the single mooring anchor chain 8 are shown in Table 1:

[0053] Table 1 Parameters of Each Section of the Mooring Anchor Chain

[0054]

[0055]

[0056] According to the above table, for a single mooring anchor chain 8, its S1 section is the anchoring foundation end for connecting to the anchoring foundation. It has the largest diameter, which can increase its own weight to maintain a certain lying-on-bottom section, thereby preventing the mooring anchor chain 8 from being tightened and generating an upward pulling force on the anchoring foundation. Its S2 section and S3 section are both intermediate sections. The S2 section uses a studless anchor chain with a smaller diameter and serves as a transition section for the S1 section to ensure that the connection point between the S2 section and the S3 section is away from the seabed, thus avoiding damage caused by friction between the S3 section and seawater. The S3 section uses a polyester cable, which can reduce the stiffness of the chain-cable combination and improve the overall buffering performance of the mooring anchor chain 8. The S4 section uses a high molecular weight polyethylene cable with high tensile strength and is used to directly connect to the corresponding anchor winch. By adopting a segmented design, the functional zoning of the mooring anchor chain 8 can be realized, reducing its failure risk and enhancing the mooring reliability.

[0057] The working process of the present invention is as follows:

[0058] When the floating platform 9 is in the operating state, a three-point mooring mode is adopted, including the following steps:

[0059] The first step is to first connect and fix the S1 section of the five strands of mooring anchor chain 8 to the mooring pile on the seabed.

[0060] Floaters are installed on each of the five strands of mooring anchor chain 8, and the corresponding mooring anchor chain 8 is identified and positioned through the floaters floating on the sea surface.

[0061] The second step: Since the floating platform 9 is used as a tourism platform with a large scale and consists of multiple modules, the main module 1 and each auxiliary module 2 are respectively transported to the target sea area by a semi-submersible transport ship. After transportation in place, the connection between the main module 1 and each auxiliary module 2 is completed.

[0062] The third step: After the splicing of the floating platform 9 is completed, the S4 sections of the five strands of mooring anchor chain 8 that have been put into the sea are respectively connected to the five main module anchor winches 3, thus completing the single-point mooring.

[0063] The fourth step: Connect the S1 sections of the other two strands of mooring anchor chain 8 to the drag anchors. At the same time, connect the S4 sections of the other two strands of mooring anchor chain 8 to the corresponding auxiliary module anchor winches 5 respectively, and slowly lower the corresponding mooring anchor chain 8 into the sea through the two auxiliary module anchor winches 5.

[0064] The fifth step: Anchor winches are respectively arranged below the two auxiliary module anchor winches 5. After the drag anchors are completely released to the seabed, the corresponding mooring anchor chain 8 is tightened to the designed pre-tension through the two anchor winches respectively, thus completing the three-point mooring.

[0065] When the floating platform 9 encounters severe sea conditions such as large wind, waves and currents that exceed the operating sea conditions, it needs to be converted to the survival state. At this time, a single-point mooring mode is adopted, including the following steps:

[0066] Step 1: Release the corresponding mooring anchor chains 8 through two wildcat winches respectively, and then slowly pull the drag anchors upward out of the seabed through two auxiliary module capstans 5.

[0067] Step 2: When continuously pulling up the mooring anchor chains 8 until they are in tight contact with the anchor brackets, tighten the corresponding mooring anchor chains 8 appropriately through two wildcat winches to prevent them from hanging excessively below the lower platform. Thus, the conversion from the three-point mooring mode (operating state) to the single-point mooring mode (survival state) is completed.

[0068] The above description is an explanation of the present invention, not a limitation thereof. For the scope defined by the present invention, refer to the claims. Any form of modification may be made within the protection scope of the present invention.
