Technical Field

[0001] The utility model relates to the technical field of dock structures, in particular to a dock extension device. Background Art

[0002] As far as berthing operations are concerned, the anti-collision pads currently equipped at the dock can only adapt to the berthing needs of conventional ships, and cannot meet the berthing requirements of special types of ships such as floating production storage and offloading vessels (FPSO). Taking FPSO as an example, its hull outer plate is equipped with auxiliary equipment including but not limited to upper and lower intakes, seawater risers, outboard pipes, etc. In particular, the lower intake, its structure is located on the port side of the ship, and its height is just near the waterline during the ship modification operation. The length of the lower intake accounts for about half of the total length of the ship, covering the entire parallel mid-body area and part of the bow and stern line area on the port side of the ship. The maximum distance between the equipment installed on it and the hull outer plate is more than 5 meters.

[0003] When the FPSO needs to berth at the port side, in order to ensure that the lower suction inlet does not collide with the anti-collision pad of the dock, the conventional berthing ball can only be arranged in the larger area of ​​the bow and stern line. Based on the dimensional data obtained from the bow and stern line measurement of the ship, under the premise of eliminating all deformation factors, in order to ensure that the actual berthing needs are met, an ultra-large diameter berthing ball needs to be selected, and the existing berthing ball size cannot meet this requirement.

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] This embodiment provides a dock extension device, such as Figure 1 and Figure 2 As shown, it includes: an inclined steel wire rope 7, a support ball 10 and a cantilever platform, wherein the cantilever platform is connected to a cable pile A on the dock through the inclined steel wire rope 7, one end of the cantilever platform abuts against the dock wall B, and the other end of the cantilever platform is used to support the support ball 10;

[0032] A dock extension device provided in this embodiment suspends a cantilever platform on a moored pile A of the dock by means of an inclined steel wire rope 7, and increases the local width of the dock with the help of the cantilever platform, thereby providing a mounting base for the dock ball 10 extending outward from the dock, effectively reducing the requirement for the size of the dock ball 10, and ensuring that the dock ball 10 installed on the cantilever platform can meet the berthing requirements of ships with protruding auxiliary equipment at the outer plate waterline such as FPSO.

[0033] In a specific embodiment, the cantilever platform includes a supporting platform and a contacting platform, one end of the supporting platform abuts against the quay wall B, the other end of the supporting platform is fixed to the contacting platform, and the end of the contacting platform away from the supporting platform is used to support the leaning ball 10;

[0034] The support platform is provided with at least two symmetrically arranged support platform lifting ears 6, one end of the inclined steel wire rope 7 is connected to the support platform lifting ear 6, and the other end of the inclined steel wire rope 7 is wound around the cable pile A;

[0035] like Figure 2 As shown, it also includes a ball-supporting wire rope 9, and at least two symmetrically arranged ball-supporting lifting ears 8 are provided on the contact platform, one end of the ball-supporting wire rope 9 is connected to the ball-supporting lifting ear 8, and the other end of the ball-supporting wire rope 9 is connected to the end of the ball 10;

[0036] In practical applications, the size of the cantilever platform needs to be designed according to the size of the auxiliary equipment protruding from the outer plate of the FPSO ship and the size of the existing spherical ball in the shipyard;

[0037] In order to prevent the original anti-collision bumper C on the dock wall B from affecting the placement of the cantilever platform, the distance between adjacent legs 3 should be larger than the size of the original anti-collision bumper C on the dock, so as to ensure that the anti-collision bumper C can be wrapped inside the cantilever platform when the cantilever platform is placed in the water;

[0038] The length of the supporting leg 3 of the supporting platform is designed according to the length required to be extended. The supporting platform lifting lug 6 is welded on the supporting leg 3. One end of the inclined wire rope 7 is connected to the supporting platform lifting lug 6 through a shackle. The other end of the inclined wire rope 7 is wound around the cable pile A at the edge of the dock for fixing. The supporting leg 3 leans against the dock wall B through the pad 5. The size of the contact surface 1 of the contact platform is determined according to the size of the supporting ball 10. The supporting ball lifting lug 8 for hanging the supporting ball 10 is welded on the contact surface 1.

[0039] The cantilever platform is installed by a crane. The height of the cantilever platform is determined according to the tide conditions in the factory. It is required that at the lowest tide level, part of the contact surface 1 needs to be sunk below the water surface to ensure that the ball 10 can contact the contact surface 1 at any tide height.

[0040] Considering the height of the shipyard pier and the tidal height, at the lowest tide level, the distance L2 between the pier and the sea surface is 4.37 meters, and at the highest tide level, the distance L1 between the pier and the sea surface is 2.67 meters. Figure 2 As shown, at the lowest tide level, the bottom 1.8 meters of the support platform will sink into the water, and the top of the support platform will be about 1.7 meters higher than the dock, so as to ensure that the support ball 10 can float on the water surface and contact the contact surface 1 at any tide level ( Figure 2 The two balls 10 shown in the figure respectively represent the relative positions of the same ball 10 at different tide levels);

[0041] When the FPSO is berthed, the hull presses against the anchor ball 10, and the pressure is transmitted to the cantilever platform through the anchor ball 10. The cantilever platform is close to the dock wall B, and the squeezing force between the ship and the anchor ball 10 is transmitted to the dock through the cantilever platform. The dock wall B provides supporting force to ensure that the cantilever platform and the anchor ball 10 can provide sufficient supporting force for the FPSO.

[0042] In a specific embodiment, Figure 1 and Figure 2 As shown, the contact platform includes a contact table 1 and a connecting pipe 4, one end of the connecting pipe 4 is fixedly connected to the supporting platform, and the other end of the connecting pipe 4 is fixedly connected to the contact table 1, and the contact table 1 is used to support the supporting ball 10;

[0043] like Figure 1 and Figure 2 As shown, the support platform includes a support table 2, a leg 3 and a pad 5, one end of the leg 3 is fixedly connected to the support table 2, the other end of the leg 3 is fixedly connected to the pad 5, and the contact platform is fixed on the support table 2;

[0044] A reinforcing bracket is provided at the connection between the contact table 1 and the connecting pipe 4, a reinforcing bracket is provided at the connection between the support table 2 and the supporting leg 3, and a reinforcing bracket is provided at the connection between the supporting leg 3 and the pad 5;

[0045] In this embodiment, the support plane 2 is a frame with a length of 7m and a width of 4.4m, which is welded by H-shaped steel with specifications of 200mm×200mm×8mm×12mm. The legs 3 are made of H-shaped steel with specifications of 400mm×408mm×21mm×21mm. A reinforcing bracket is provided at the connection between the legs 3 and the support plane 2 (the three are connected by welding). The thickness of the reinforcing bracket is 12mm, and the weld foot is not less than 8mm.

[0046] In order to ensure a sufficiently large contact area with the wharf quay wall B, a pad 5 with a diameter of 1000mm and a thickness of 20mm is provided at the end of the leg 3, and a reinforcing bracket is provided at the connection between the leg 3 and the pad 5 (the three are connected by welding). The thickness of the reinforcing bracket is 12mm, and the weld foot is not less than 8mm;

[0047] Four supporting platform lifting ears 6 (10-ton lifting ears are selected) arranged opposite to each other in pairs are welded on the supporting legs 3. One end of the inclined steel wire rope 7 is connected to the supporting platform lifting ear 6 through a shackle. The other end of the inclined steel wire rope 7 is wound around the cable pile A at the edge of the dock. The inclined steel wire rope 7 is locked by the shackle, so that the cantilever platform can be fixed on the dock. The supporting platform lifting ear 6 is also used for the transportation and lifting of the cantilever platform.

[0048] The contact platform is a frame with a length of 10m and a width of 8m, which is welded by H-shaped steel with specifications of 200mm×200mm×8mm×12mm. Four ball lifting ears 8 (5-ton lifting ears are selected) for hanging the ball 10 are welded on both sides of the top of the contact table 1. One end of the ball wire rope 9 is connected to the ball lifting ear 8 through a shackle, and the other end of the ball wire rope 9 is connected to the eye plate on the end flange of the ball 10 through a shackle, so that the ball 10 can be pulled by the ball wire rope 9. The diameter of the ball 10 is about 3800mm.

[0049] The support plane 2 and the contact table 1 are connected by a connecting pipe 4 with a diameter of 150 mm. A reinforcing bracket is provided at the connection between the connecting pipe 4 and the support plane 2, and a reinforcing bracket is provided at the connection between the connecting pipe 4 and the contact table 1. Both are connected by welding. The thickness of the reinforcing bracket is 12 mm, and the welding foot is not less than 8 mm.

[0050] After the cantilever platform is welded, it needs to be surface treated. The treatment requirement is to reach Sa2 level. Then, yellow anti-rust paint is applied on the surface of the cantilever platform to complete the production of the cantilever platform.

[0051] Different sizes of docking balls 10 and cantilever platforms can be used according to the actual ship type. The dock extension device provided by the utility model has the characteristics of simple structure, convenient manufacturing, light weight, easy installation, easy storage and reusability. By increasing the outward extension width of the dock, the collision between the protruding auxiliary equipment on the hull and the dock is effectively avoided, and the maneuverability and flexibility of the dock are improved. It can not only meet the berthing needs of FPSO, but also adapt to the berthing of other ships with protruding auxiliary equipment at the waterline of the outer plate. It has the advantages of low economic cost and high use value, effectively improves the working efficiency of the dock, reduces construction cost, and improves production efficiency.
