Abstract
The invention discloses a boarding and disembarking operation mode for a large ocean structure. The boarding and disembarking operation mode comprises boarding operation and disembarking operation. A groove with the size larger than that of the appearance of the ocean structure is formed in the tail of a main deck of a ship. The boarding operation comprises the processes of ship tail tilting, ocean structure recycling and positive ship floating. The disembarking operation comprises the inverse processes of the boarding operation. During operation of the ocean structures of the same size and weight, boarding and disembarking of the large ocean structure can be achieved only by adopting a small-displacement ship, the risk operation that a crane ship adopts the on-sea crane operation mode is avoided, and the problem that the space of the ship body with a cargo deck completely submerged below the water is wasted due to the fact that a semi-submerged ship is provided with a plurality of water ballast spaces is avoided.
