Benefits of technology
The present invention provides a pressure balance type floating body that can be continuously installed underwater at one step and can prevent damage to the bulkheads of the floating body. The technical effect is an improved installation efficiency and cost reduction as no underwater operation is carried out. The floating body can be installed without the help of an underwater operating system (ROV), and the service lives of the gas cabins and the water cabins are prolonged. The position of the buoyant center and the gravity center of the floating body are located on the same vertical line, and the apparatus can inflate the gas cabins according to the external water pressure to make the pressure in the gas cabins consistent with the external water pressure, thereby preventing damage to the floating body. The gas cabins provide an upward buoyant force to stably submerge the floating body. The entire process of installing and using the floating body is simple, controllable, and efficient, and no underwater operation is carried out.
Problems solved by technology
In the traditional underwater floating body, the floating body is inflated to generate a larger pressure in the floating body so as to balance the external water pressure of the floating body, namely the internal pressure of the floating body is increased by inflation when the floating body is located at any underwater position to make the internal pressure of the floating body be equivalent to the external water pressure, so as to protect the structure of the floating body form being damaged by higher water pressure, and for the above reasons, the installation process of the traditional underwater floating body is relatively complicated.
Moreover, the installation process of the traditional underwater floating body is completed underwater by a control system under the help of an underwater operating system (ROV), thus the installation process is difficult to achieve.
The existing pressure control system cannot continuously control pressure and fails to achieve real-time measurement and real-time control.

Embodiment Construction
[0024]See FIG. 1 to FIG. 4, the present invention provides a pressure balance type floating body, including the body of the floating body, gas cabin inflation valves, water cabin water supply systems, water cabin ventilating systems, a first controller, a posture monitoring system and underwater even pressure control systems used for controlling the gas pressure in the body of the floating body. The interior of the body of the floating body is divided into at least one water cabin 1 and at least one gas cabin 2, the water cabin 1 and the gas cabin 2 are merely two different types of cabins in the floating body, and the materials and the connecting manners of the two types of cabins should meet the requirements of good sealing property. At first, the structures of the water cabin 1 and the gas cabin 2 are described, the water cabin 1 and the gas cabin 2 are formed by welding plates with different specifications, specifically: plates with the same material and thickness are adopted, d...

The present invention relates to the technical field of ships, and particularly relates to a pressure balance type floating body and an installation method thereof. The floating body includes water cabins, gas cabins, gas cabin inflation valves, underwater even pressure control systems, water cabin water supply systems and water cabin ventilating systems. The buoyant center of the floating body and the gravity center of the floating body are located on the same vertical line, and the position of the buoyant center of the floating body is higher than the position of the gravity center of the floating body. The gas cabin inflation valve is arranged on each gas cabin, and the gas cabin inflation valve is connected with each underwater even pressure control system. The water cabin water supply system and the water cabin ventilating system are arranged on each water cabin.
Description
RELATED APPLICATIONS[0001]This application is a United States National Stage Application filed under 35 U.S.C 371 of PCT Patent Application Serial No. PCT / CN2013 / 079280, filed Jul. 12, 2013, which further claims priority of PCT Patent Application Serial No PCT / CN2013 / 073378, filed Mar. 28, 2013, the disclosure of all of which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates to the technical field of ships, and particularly relates to a pressure balance type floating body and an installation method thereof.BACKGROUND OF THE INVENTION[0003]As offshore oil and gas resource development equipment, a floating production storage and offloading device (FPSO) is widely applied to oil and gas development under various water depth conditions. For a deepwater floating production storage and offloading device (FPSO), the working position of an underwater floating body thereof is generally in deep water, and the exterior of the float...
