摘　　要：采矿船作为多金属结核采矿试验支持船舶,采矿作业较频繁的通过船中处月池进行硬管和中继站等作业装置的布放回收。船舶在波浪中的运动以及月池内部水体的运动有可能造成甲板上浪以及采矿装置的碰撞损坏,从而影响采矿作业的安全性。本研究提出在月池内部适当地设置防撞装置和阻尼装置,可以有效减小波面升高并能承受一定的碰撞接触,有效地扩大作业窗口期。本文首先采用频域计算方法分析了不同海况下采矿船的运动和月池波面升高情况,进一步研究提出了月池内部防撞消波装置设计方案,并通过水池模型试验的方式论证了该装置在减小月池内部波面升高的有效性,该研究成果对提高深海采矿布放作业率有重要的参考意义。As a support vessel for mining experiments of polymetallic nodules,the mining vessel adopts the engineering ship type of derrick and moonpool.The steel pipes and relay stations and other operating devices were deployed and recycled through the moonpool.Due to the movement of the ship in the waves and water movement inside the moonpool,it is possible to cause the green water on the deck and collision damage between the moonpool and mining equipment,which affecting the safety of mining operations.The anti-collision and wave eliminating devices on the inner wall of the moonpool were proposed.When the size of the moonpool is limited,the devices can effectively reduce the elevation of wave surface and can withstand a certain collision contact,which can effectively expand the operating window.Firstly,this paper uses frequency domain calculation methods to analyze the movement of the mining ship and the wave surface elevation in the moonpool,and further proposes the design for the internal anti-collision and wave elimination devices of the moonpool.The wave elimination function was verified by model test.The research results of this paper have important reference significance for improving the operating rate of deepsea mining.
