Abstract: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.
