Description
Technical Field
The invention relates to the field of ocean platform anti-collision, in particular to an anti-collision protection device of a deepwater semi-submersible type supporting platform.
Background
With the great development of ocean engineering, world ocean energy development is developed from offshore shallow water areas to more complicated and dangerous deep sea areas, the working environment of large ocean platforms is more and more severe, and various risks such as collision accidents occur. Deep water semi-submersible support platforms often require berthing connections through connection trestle in order to provide personnel life and related support services for large offshore production platforms. During long-term offshore operations, the risk of collision between the support platform and the production platform is unavoidable. The connection trestle base is located at the head or broadside of the support platform, protruding outside the upper deck structure, most susceptible to impact. In order to effectively reduce the risk of collision damage to the support platform connecting trestle base and increase the structural safety reliability of the ocean platform, an anti-collision system capable of effectively protecting the connecting trestle base and the deep-water semi-submersible support platform needs to be designed. In view of the fact that the deep sea environment of the deep water semi-submersible type supporting platform in the working sea area is severe, collision load is large, and the anti-collision effect of an anti-collision facility becomes a primary problem.
The current collision scenarios caused by long-term frequent close-range offshore contacts include: an accident that a supply ship collides with an ocean platform frequently occurs when the supply ship berths to supply the ocean working platform; the second is that the shuttle oil tanker collides with the floating production and storage and unloading device/floating oil storage platform when in crude oil conveying operation; the risk of collision of the deep water semi-submersible support platform in close contact with the berthing ocean work platform is high. Compared with the former two collision scenes, the marine environment supporting the collision risk of the platform is more severe, the collision load is larger, the collision structure position is weaker and more fragile, and the accident result is more serious. At present, no targeted protection measures exist, so that an anti-collision facility for protecting a deepwater semi-submersible support platform needs to be designed, and engineering requirements such as good anti-collision effect and reliability are met while the applicability requirement of the anti-collision facility is met.

Drawings
The invention is described in detail below with reference to the attached drawings and detailed description:
FIG. 1 is a schematic diagram of the structure of the present invention;
Fig. 2 is a cross-sectional side view taken along line A-A in fig. 1.
Detailed Description
As shown in fig. 1 and 2, the collision guard of the deep water semi-submersible support platform of the present invention is composed of a main collision guard 1110 and two subsidiary support force transmission portions 1140.
The support platform 100 comprises a platform main body 101 and a protruding part 102 protruding out of the platform main body 101, and an upper deck is welded on the platform main body 101 and the protruding part 102. The front end of the protruding portion 11 has a base 110.
The main anti-collision part 1110 and the auxiliary supporting force transmission part 1140 are made of steel plates, and the steel plates are made of high-strength steel with the thickness of 12 mm.
Specifically, main impact 1110 is surrounded by upper deck 1111, peripheral wall 1112, and floor 1113 to form a semi-circular ring structure, located around the front half of base 110. The steel boot of the main impact portion 1110 is divided into a plurality of compartments by a steel plate 1114, and the compartments are filled with a composite material 1120. The composite material is a paulownia wood sandwich glass fiber composite material. A gap of 100mm is provided between the main impact portion and the base 110. A gap is formed between the main anti-collision part and the base 110, so that collision force is not directly transmitted to the base 110, and the base is protected. The radial width of primary impact portion 1110 is 2400mm.
The primary impact portion 1110 and the secondary support force transfer portion 1140 have only outer peripheral wall panels and no inner peripheral wall panels.
In this embodiment, the bottom of the base 110 has a slope 111 recessed toward the support platform side, and thus the bottom plate 1113 of the guard is located just at the upper edge of the slope 111.
The two auxiliary supporting force transmission parts 1140 are symmetrical structures, have included angles of 30 degrees and are respectively positioned on the left side and the right side of the base 110; one end of the left auxiliary supporting part is connected with the left end of the main collision preventing part 1110, and the other end is connected with the left part of the supporting platform 100; one end of the right auxiliary supporting part is connected with the right end of the main anti-collision part 1110, and the other end is connected with the right side part of the supporting platform.
In this embodiment, the main impact-resistant portion 1110 and the two accessory support force-transmitting portions 1140 are tiled on top of each other to form the upper deck of the guard and are flush with and integral with the upper deck of the support platform 100. The peripheral wall of the sub-support force-transmitting portion 1140 naturally extends to the support platform 100 in a tangential direction at the peripheral wall end of the main impact-resistant portion. The inner edge of the auxiliary supporting force-transmitting portion 1140 naturally extends to the supporting platform 100 along the tangential direction at the end of the inner edge of the main anti-collision portion, and the inner edge of the auxiliary supporting force-transmitting portion 1140 is connected with the supporting platform 100 by a rounded corner with a radius of 1000mm.
The steel casing of the main impact-resistant portion 1110 is integrally connected with the steel casing of the accessory support force-transmitting portion 1140 by an end-face steel plate 1130. Specifically, the terminal surface steel sheet adopts connecting bolt to connect, easy dismounting.
By adopting the technical scheme, after the support platform is connected with the trestle base and the external energy dissipation anti-collision sleeve box collides with the working platform structure, huge collision kinetic energy realizes buffering and energy absorption through the sunken damage of the steel plate of the main anti-collision part and the abrupt compression of the composite material, and the auxiliary support force transmission part disperses and transmits part of collision force, so that the local extrusion deformation damage of the base and the impact on the support platform structure caused by the concentrated transmission of the collision force are prevented, the base and the platform structure are effectively protected, and the safety and the reliability of the platform structure are improved. In addition, the sleeve box of the whole anti-collision protection device consists of three independent units, can be disassembled and assembled in a bolt connection mode, is convenient to transport and install, and is convenient to maintain and replace after each unit is damaged.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for the purpose of limiting the invention, and that variations and modifications of the above described embodiments will fall within the scope of the claims of the invention as long as they fall within the true spirit of the invention.
