Description

Technical Field

[0001] The invention relates to a method for launching and retracting a marine submersible, and belongs to the technical field of ships and marine engineering. Background Art

[0002] According to the existing wave scatter diagram data, there is a high probability of sea conditions above level 6. However, the existing marine submersible transport ships usually use a hoisting method to lift the marine submersible to the deck or the operating sea area. This method is easily affected by the wind and waves at sea during operation. Not only is the efficiency of retrieval and release low, but it is also easy to cause the marine submersible to collide with the hull, causing damage to the marine submersible; or the transport ship uses a semi-submersible ship method to achieve the retrieval and release of the marine submersible by floating up and sinking the hull. This semi-submersible method has high requirements for the change of ship ballast water, which is easy to cause the ship to be fat and have many water pumps, greatly increasing the production and operation costs of the ship. In addition, the above two methods of retrieval and release of marine submersibles can only recycle the marine submersible to the deck, and the fixation and movement of the marine submersible are greatly affected by the marine environment. Due to the above reasons, it is difficult for existing marine submersible transport ships to operate in sea conditions above level 6, resulting in a short operation window period, and it is difficult to safely and efficiently complete the retrieval and release of marine submersibles.
