Problems solved by technology

These devices can reduce the damage to the buoyancy tank, guide frame and central well surrounding wall due to mutual collision, but it does not help to reduce the difficulty of buoyancy tank installation, and even the device itself takes up a certain amount of space, which reduces the installation clearance of the buoyancy tank , increasing the installation difficulty of the buoyancy tank

Abstract

The invention discloses a gasbag type buoyancy tank support device for a SPAR platform. The gasbag type buoyancy tank support device has the characteristics that the gasbag type buoyancy tank support device comprises an upper support guiding frame, a lower support guiding frame, a plurality of support device bodies and buoyancy tanks; the upper support guiding frame directly faces the lower support guiding frame; the inner wall of the upper support guiding frame and the inner wall of the lower support guiding frame are provided with the multiple support device bodies correspondingly, and the sizes of the support device bodies are variable; and the buoyancy tanks are arranged in the upper support guiding frame and the lower support guiding frame, and gaps are reserved between the multiple support device bodies and the outer walls of the buoyancy tanks. With the usage of the gasbag type buoyancy tank support device for the SPAR platform, the working gaps of the buoyancy tanks can be adjusted effectively according to different working conditions of installation and overhauling of the buoyancy tanks and normal operation of the platform, thus the convenience of installation and overhauling of the buoyancy tanks is improved, and the service life of the buoyancy tanks is prolonged.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an airbag type buoyancy tank support device of a SPAR platform. Background technique [0002] The riser system of the SPAR platform is located in the central well, connected upward to the production equipment of the upper module, and downward to the seabed. Buoyancy tanks are commonly used as a riser tensioning device for SPAR platforms. The buoyancy tank is located in the central shaft, which is filled with air and provides riser tension by its own buoyancy, keeping the vertical riser in tension at all times. Because the main body of the SPAR platform is decoupled from the buoyancy tank riser system, and there is a gap between the buoyancy tank support guide frame and the buoyancy tank, the buoyancy tank will collide with the guide frame during the relative movement with the platform main body. The long-term repeated action of the collision load will cause the fatig...
