Small water plane twin-hull platform

Abstract

The invention relates to the technical field of marine engineering equipment, in particular to a small water plane twin-hull platform. The small water plane twin-hull platform comprises an upper layer building, a supporting structure and an underwater floating body, wherein the upper layer building is located on the underwater floating body, and the underwater floating body supports the upper layer building through the supporting structure; the supporting structure is a truss-type structure; and the underwater floating body comprises two small water plane sheet bodies which are arranged at the two ends of the truss-type structure correspondingly. The truss-type structure serves as the supporting structure, the problems on the aspects of strength and rigidity of a large-span structure are effectively solved, and the performance of the platform is improved. As the small water plane twin-hull platform is in a semi-submersible state when fixed and working and the water plane position is of the truss-type structure, the wind and wave resistance is improved. Meanwhile, as the underwater floating body includes the small water plane sheet bodies, the whole platform has good sailing performance in the sailing process, the interference function of sea waves is obviously weakened, and the small water plane twin-hull platform has good seakeeping performance, maneuverability and shipping-direction stability.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a small waterplane two-body platform. Background technique [0002] At present, there are three basic types of ultra-large floating structures available for selection, namely, box type (also called plate type), semi-submersible type and row type. [0003] Box structures are flat, closed, "hollow plate" structures whose height is much smaller than the span. The structure of the box-type platform is simple, the difficulty of construction and assembly is small, and the cost is low. Its draft is very shallow and can be installed in offshore waters. However, due to the large length-to-height ratio of the box structure, the rigidity and strength are very low, so it has a large coupling area with the water surface, and the motion response and load response in waves are extremely large. In order to prevent excessive wave load response, excessive movement, and struc...

Problems solved by technology

In order to meet the requirements of loading capacity, the row-type structure platform needs to arrange a large number of buoys, which increases the resistance of the row-type structure platform when avoiding typhoons, and its maneuverability is relatively poor

In addition, there is still no good solution for the deep-sea positioning of the row structure platform
