Single-layer inclined-type wave wall structure of offshore oil floating platform

Abstract

The invention relates to the technical field of offshore oil engineering, and discloses a single-layer inclined-type wave wall structure of an offshore oil floating platform. The structure comprises wave wall bodies with different forms of sovereignty, a vertical support, a horizontal support, a water retaining wall, a drainage facility, drainage holes, ventilation holes and the like. The wave wall bodies are arranged between two layers of decks or on a broadside above the decks by adopting a plurality of groups of inclined plane structures similar to a shutter form, and the vertical support is a vertical steel structure and is welded on and supports the wave wall body. According to the single-layer inclined wave wall structure of the offshore oil floating platform, the wave wall main body is mainly used for providing wave slapping protection and ventilation functions for the floating platform, so that equipment and facilities on the decks are protected, and the implementability, safety and reliability of the floating platform are improved; and the wave wall structure is composed of a supporting structure, the drainage facility, an auxiliary ventilation part and the like, a plate girder structure formed by welding steel plates or profiles is adopted, the weight is small, construction is easy, and investment is saved.

Description

technical field [0001] The invention relates to the technical field of offshore oil engineering, in particular to a single-layer inclined wave wall structure of an offshore oil floating platform. Background technique [0002] Offshore floating platforms are conventional equipment for offshore oil development, including platforms with different functions such as drilling platforms and production platforms. There are ship-type, cylindrical-type, semi-submersible and so on in shape. Among them, the cylindrical and ship-type floating platforms usually include drilling platforms and floating oil storage and offloading production platforms. Two or more layers of additional decks are usually set on the FPSO to prevent oil, gas, and water treatment devices. The top is called the main deck, and the upper deck is the craft deck. Cylindrical and ship-shaped floating platforms usually have a small freeboard. Under harsh marine environmental conditions, such as the once-in-a-century env...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a single-layer slanted wave wall structure for offshore oil floating platforms, which can solve the problem that existing floating platforms often need to consider harsh sea conditions during on-site operations, and there will be upper decks above the main deck. The problem of waves, the main deck and its above equipment and facilities are vulnerable to the risk of breaking waves, resulting in difficult construction and huge investment costs; this device provides wave protection and ventilation functions for the floating platform by setting a wave retaining wall. The equipment and facilities on the deck are protected, the effect is obvious, and the operability, safety and reliability of the floating platform are improved; the wave wall structure is composed of the main body, supporting structure, drainage facilities, auxiliary ventilation and other parts, and adopts steel plates or profiles The plate girder structure formed by welding is light in weight, simple in construction, saves investment, and effectively solves the problem of preventing waves from entering the deck area. At the same time, a certain number of wave retaining wall combinations can play the role of breaking waves, and at the same time reduce the waves climbing along the side. The speed and height satisfy the flow of personnel and heat dissipation of equipment between the two decks, eliminating the risk of combustion and explosion in the closed space between the two decks; the resistance can be improved with less steel weight The ability of waves to beat loads; collect and treat seawater that cannot be discharged to prevent seawater residues on the deck
