[0001] The utility model relates to wharf technical field especially relates to a novel high-pile LNG wharf. BACKGROUND
[0002] China is the main import country of international LNG trade market, considering that large LNG ships are good in economy, domestic main LNG receiving stations generally only consider large LNG ships with cabin capacity of 80,000 cubic meters or more when constructing, and small ships are generally not considered, such as Guangdong Dapeng LNG wharf can reliably berth 8-21.7 million cubic meter ships, and Zhuhai Jinwan LNG wharf can reliably berth 8-27 million cubic meter LNG ships. In order to avoid process equipment platform displacement and shaking, domestic high-pile LNG wharfs generally do not design ship-berthing fenders on the process equipment platform, and retreat the process equipment platform, and LNG ships only berth on the ship-berthing piers on the left and right sides of the process equipment platform. Due to large size of the process equipment platform, the distance between the ship-berthing piers on the left and right sides is large, and small LNG filling ships cannot be compatible. In recent years, with international ships starting to use LNG as power fuel, LNG filling demand is generated, and small LNG filling ships fill large LNG power ships. The cabin capacity of the LNG filling ships is mainly below 20 million cubic meters, therefore, domestic LNG wharfs increase the berthing demand of small LNG filling ships. At the same time, due to the layout of LNG receiving stations in inland rivers, small LNG transport ships also begin to emerge. At present, there are examples of small LNG wharfs combined with large LNG wharfs, but the investment is large, and the construction difficulty is large. Therefore, it is urgent to solve the problem.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0024] EMBODIMENT
[0025] Referring to Figs. 1-3 as shown in the drawings:
[0026] The utility model provides a novel high-pile LNG wharf, which comprises a working platform 10 arranged in a sea area where LNG ships are docked. The rear end of the working platform 10 is connected to the land through a trestle, and both ends of the working platform 10 are provided with main ship docking piers 20a for docking large LNG ships. The front end of the working platform 10 is used for berthing LNG ships, and the front end of the working platform 10 is provided with a notch 12. The notch 12 is provided with an auxiliary ship docking assembly for docking small LNG ships. The structure of the auxiliary ship docking assembly is independent of the structure of the working platform 10.
[0027] The auxiliary berthing assembly is independent of the structure of the working platform 10, so that the front end of the working platform 10 can directly dock with a small LNG ship. This not only enables a large LNG high-pile wharf to dock with a small LNG ship, but also conforms to the design convention of a domestic petroleum and chemical working platform not to be berthed, and avoids displacement of the working platform caused by impact when the ship is berthed, thus eliminating safety hazards.
[0028] The standard counterforce fender 31 is arranged on the main berthing pier 20a, and the low counterforce fender 32 is arranged on the auxiliary berthing assembly. The standard counterforce fender 31 and the low counterforce fender 32 are arranged on the same line. This changes the structure of an existing equipment platform using a retraction process, so that the distance between the working platform 10 and the ship is reduced, regardless of whether a small LNG ship or a large LNG ship is docked, thus facilitating daily operations between the ship and the working platform 10.
[0029] The auxiliary berthing assembly also includes a load-bearing grid 40 for personnel walking. The auxiliary berthing pier 20b is arranged in the gap 12 of the working platform 10. The auxiliary berthing pier 20b has the same shape as the gap 12, and a gap exists between the auxiliary berthing pier 20b and the working platform 10, thus forming an embedded structure. The distance between the rear end of the auxiliary berthing pier 20b and the working platform 10 is generally 500 mm, and the distance between the two sides of the auxiliary berthing pier 20b and the working platform 10 is also generally 500 mm.
[0030] The top surface of the auxiliary berthing pier 20b is lower than the top surface of the working platform 10. The load-bearing grid 40 has the same shape and size as the top end of the gap 12, and is arranged in the gap 12. The upper surface of the load-bearing grid 40 is flush with the top surface of the working platform 10, and the lower surface of the load-bearing grid 40 is in contact with the top surface of the auxiliary berthing pier 20b.
[0031] Through such an arrangement, the structure of the working platform 10 and the auxiliary berthing pier 20b is independent of each other, and the daily operation of the working platform 10 is not affected.
[0032] In addition, in order to ensure safety, a groove is arranged on the side wall of the top end of the gap 12, so that the rear end of the load-bearing grid 40 is detachably connected or hinged to the working platform 10, and the two sides of the load-bearing grid 40 are clamped and connected to the grooves on the two side walls of the top end of the gap 12.
[0033] In order to reduce the impact force of the load-bearing grid 40 on the auxiliary berthing pier 20b when the ship is berthed, the bottom surface of the load-bearing grid 40 is slidably connected to the top surface of the auxiliary berthing pier 20b.
[0034] In specific use, a plurality of support steel beams are arranged on the bottom surface of the load-bearing grid 40, the top ends of the support steel beams are fixedly connected with the bottom surface of the load-bearing grid, and the bottom ends of the support steel beams are placed on the top surface of the auxiliary berthing pier 20b.
[0035] In addition, a mounting groove can be arranged on the bottom end of the support steel beam, a roller is arranged in the mounting groove, and the roller is placed on the top surface of the auxiliary berthing pier 20b. When the auxiliary berthing pier 20b is slightly offset due to the impact force when the ship docks, the load-bearing grid 40 is not moved, and the safety of daily operation is improved.
[0036] In addition, the bottom of the working platform 10, the main berthing pier 20a and the auxiliary berthing pier 20b are each provided with a concrete pile 11 for support, and the concrete piles 11 at the bottom of the main berthing pier 20a and the auxiliary berthing pier 20b are each designed to be reinforced, for example, the diameter is thickened, and the foundation of the pile is deepened to bear more impact force generated when the ship docks.
[0037] It should be noted that if the embodiments of the present application involve directional indications such as up, down, left, right, front, back, etc., the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture, such as shown in the drawings, and if the specific posture changes, the directional indications also change accordingly. In addition, if the embodiments of the present application involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes, for example, "A and / or B" includes A scheme, or B scheme, or A and B simultaneously meet the scheme.
