[0009] Figure 2 The outer side piers are symmetrically arranged according to this utility model. Detailed Implementation
[0010] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0011] This utility model provides a side pier for forming locking angles on both sides of the bottom of the vessel to be rescued (5), preventing the vessel to be rescued (5) from swaying left and right when being loaded and placed, and ensuring stability after placement. The 6 sets of side piers are further divided into 4 sets of inner side piers and 2 sets of outer side piers, which have similar basic structural forms but slightly different external dimensions.
[0012] This utility model provides a side pier, including: inner side pier and outer side pier; 4 sets of inner side piers are set on both sides of the bottom of the middle of the vessel to be rescued (5), and 2 sets of outer side piers are set on both sides of the bottom of the front and rear of the vessel to be rescued (5);
[0013] The inner side piers, from bottom to top, include: inner bottom pier (2), pier (3) and rubber plate (4). The bottom surface of the inner bottom pier (2) is flat and is installed on the deck (1) of the semi-submersible vessel. The upper surface is flat and is inclined at a certain angle to the deck (1) of the semi-submersible vessel. The bottom of the pier (3) is flat, and the upper surface is an arc shape that fits the bottom streamline of the vessel (5) to be rescued. The rubber plate (4) is installed on top of the pier (3).
[0014] The outer side pier, from bottom to top, includes: outer bottom pier (7) and semi-circular fender (6). The bottom surface of the outer bottom pier (7) is flat and is installed on the semi-submersible deck (1). The upper surface includes a horizontal surface and an inclined surface that is inclined at a certain angle to the semi-submersible deck (1). One semi-circular fender (6) is installed on the horizontal surface and three semi-circular fenders (6) are installed on the inclined surface.
[0015] To maintain versatility, all inner side piers are the same size. The inner bottom pier (2) is a steel structure bottom pier, and the contact surface between the inner bottom pier (2) and the pier (3) is a plane with a length of 1860mm. The inner bottom pier (2) has a length of 1200mm along the length of the ship and a length of 2600mm along the width of the ship. Its height is perpendicular to the semi-submersible deck (1) on one side and perpendicular to the upper surface of the inner bottom pier (2) on the other side to better withstand the pressure on the steel pier from the loading of the vessel to be rescued (5). The maximum height is 2000mm. The inner bottom pier (2) is provided with weight reduction holes, and the weight of a single side pier is 1001.2kg.
[0016] The dimensions of the block (3) are 178×267×300×1600. The bottom of the block (3) is flat, and the upper surface is an arc that fits the bottom streamline of the vessel (5) to be rescued. The lowest point in the middle of the arc is 178mm high, the two shoulders of the arc are 267mm high, the width is 300mm, and the length is 1600mm.
[0017] The rubber sheet (4) has dimensions of 30×900×1600mm, that is, a thickness of 30mm, a width of 1600mm, and a length of 900mm. Three sets of piers (3) and a whole piece of rubber sheet (4) are arranged in parallel on the inner side piers of each group, and four sets of wide nylon binding straps are used to bind them evenly perpendicular to the length direction of the piers (3).
[0018] The inner side pier is used to provide support after the rescue vessel (5) is loaded and placed on the pier. The vertical component of the support force provides vertical support force, and the horizontal component prevents the rescue vessel (5) from swaying left and right when it is loaded and placed, ensuring stability after placement.
[0019] Among them, the two sets of outer side piers have similar structural forms to the inner side piers, but with slightly different dimensions. The outer bottom pier (7) is a steel structure bottom pier. To reduce the impact during the loading and unloading process of the vessel to be rescued (5), a semi-circular fender (6) with a height of 500mm is installed on the upper surface of the outer bottom pier (7). The outer bottom pier (7) is 1500mm long along the ship's length direction and 2600mm long along the ship's width direction. Its height direction is perpendicular to the semi-submersible deck on one side and perpendicular to the upper surface of the side pier on the other side, so as to better withstand the pressure brought by the loading of the vessel to be rescued (5) on the steel pier. The maximum height is 2000mm. Weight reduction holes are also provided on the outer bottom pier (7).
[0020] The lower surface of the outer bottom pier (7) of the outer side pier is welded to the semi-submersible deck (1) at the specified position. A set of outer side piers includes two outer bottom piers (7). The upper surface of each outer bottom pier (7) is arranged with a set of 4 semi-circular fenders as required. One semi-circular fender is used to withstand the impact force during the loading process of the vessel to be rescued (5), and the other 3 are used to provide support force after the vessel to be rescued (5) is loaded and placed on the pier. The vertical component of the support force provides vertical support force, and the horizontal component prevents the vessel to be rescued (5) from swaying left and right when it is loaded and placed, ensuring stability after placement. There are a total of 4 semi-circular fenders (6) on the 2 sets of outer side piers to withstand the impact force during the loading process of the vessel to be rescued (5), and a total of 12 semi-circular fenders to provide support force after the vessel to be rescued (5) is loaded and placed on the pier. The semi-circular fender (6) is 1.5m long, 0.5m high, and 0.5m wide.
[0021] This utility model provides a side pier, including an inner side pier and an outer side pier. According to the load-bearing requirements of the bottom sides of the vessel to be rescued (4), this utility model designs two different side piers. The two different side piers support the bottom sides of the vessel to be rescued (4) together, which not only provides stable support, but also minimizes the damage to the vessel to be rescued (4).
[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
