Embodiment Construction
[0022] The present invention will be further described below in conjunction with drawings and embodiments.
[0023] Such as Figure 1~Figure 6 As shown, this embodiment includes a vibration damping cabin 1 and a sloshing cabin 2 arranged vertically on the lateral inner walls 10 at both ends of the moon pool. The vibration damping cabin 1 and the sloshing cabin 2 are separated by a watertight partition 3 . The outer wall 11 of the damping cabin and the lower outer wall 21 of the sloshing cabin are respectively horizontally placed with several rows of staggered damping blocks 4, the outer wall 21 of the lower part of the sloshing cabin is fixedly connected with four wave-blocking columns 5 with the same width as the moon pool, above the middle of the sloshing cabin There is no vertical outer wall, and three-layer partitions 22 are arranged up and down in the sloshing reduction cabin 2. Eight rows of vertical wave-dissipating blocks 6 are placed horizontally on the upper and lowe...
