Description
Technical Field
The invention relates to the technical field of an alongside system between two ships, in particular to an elastic sleeve type alongside system for alongside connection between two ships.
Background
At present, two modes are connected between two ships on the sea: series connection and side connection. The serial connection is that two ships are connected in series head and tail or tail and tail, and the distance of 60-100 m is kept between the ships. The side-by-side connection means that two ships are arranged side by side, and the ship boards are connected in a side-by-side manner. The two modes are generally connected by cables, and the tugboat is used for towing the two ships reversely, so that the two ships are prevented from colliding. Two ocean nuclear power platforms are moored on a single-point mooring after being connected in a series-lean connection mode, so that the area of the occupied sea area is large, and the advantages brought by the wind vane effect are lost; if the connection is by way of a side by side connection, a certain distance also needs to be maintained. When the mooring rope is used for mooring two ships, the mooring rope is in a tensile state for a long time, fatigue damage is easy to occur, and reliability is poor.
The marine nuclear power platform is a ship-borne floating nuclear power station, is anchored in the sea for a long time, is fixed in a specific sea area by a single-point mooring system, and can rotate around a single point. The single point mooring system can only moor one ship, occupies a large sea area, has high investment cost and has serious resource waste.
Based on the above analysis, it is very necessary to develop a leaning system suitable for an offshore nuclear power platform, so as to lean two or three ships together at sea to connect them into a whole, and use the same single-point mooring system, thereby saving the construction cost of the single-point mooring system, reducing the area occupied by the sea, solving the problems of easy fatigue damage of flexible connection of cables, huge bridge-type rigid connection structure, local reinforcement of the connected ship structure, and the like, and relieving the dependence of the leaning connected ship on tugs.
