Ship floating body device with high seakeeping performance

Abstract

The invention discloses a ship floating body device with high seakeeping performance. The ship floating body device comprises a upper-layer building, a plurality of stand columns arranged at the bottom of the upper-layer building and a plurality of float cylinders arranged on the stand columns in a sleeving mode. Each stand column is provided with a vibration reduction device, and the vibration reduction devices are located between the upper-layer building and the float cylinders. A base is arranged at the bottom of the stand column and connected with the float cylinder in a sliding mode. A plurality of springs are arranged between the inner wall face of the top of the float cylinder and the outer wall face of the top of the base, and a plurality of springs are arranged between the inner wall face of the bottom of the float cylinder and the outer wall face of the bottom of the base. The overwater part and the underwater part of the ship floating body device are separated and are connected through the stand column with the small waterline surface, so that the waterline surface area of the ship body is reduced, and the sensitivity of the ship floating body device to waves is reduced.Besides, the vibration reduction devices and the springs are installed on the stand columns, the floating body motion response under the wave effect can be reduced, and therefore the stability of theupper-layer building is further improved.

Description

technical field [0001] The invention relates to the technical field of ship floating body design, in particular to a ship floating body device with high seakeeping performance. Background technique [0002] Ships and marine buoys, as the most important vehicles for marine transportation and platforms for ensuring offshore production operations, have always been developing in the direction of large-scale and high-speed. There are waves on the sea surface for more than 70% of the time, and the floating body of the ship will have a relatively large motion response in severe sea waves. Violent swaying movement will not only reduce the working ability of the personnel and equipment on board, but may even cause disasters such as ship capsizing. [0003] Traditional displacement ships or marine buoys have a large water surface area and are highly sensitive to waves, so they are prone to six-degree-of-freedom swaying motions under the action of waves. In addition, conventional dis...

Problems solved by technology

In addition, traditional ship design and construction usually requires the assembly of hundreds of transverse cabin sections, and the structural forms of each section are complex and different, resulting in serious waste of materials during production and processing, and a longer design and construction cycle
