Problems solved by technology

In order to seek a higher utilization rate of the dock and shorten the construction period in the dock, the shipyard has optimized in many aspects, including adding the middle dock door of the dock, improving the reserve of the number of loading sections and loading efficiency, and maximizing the total group and unit modules, etc. etc. However, for the construction of large ships with different docking periods, in order to improve the utilization rate of the dock and ensure the undocking cycle of the ship, it is inevitable to adopt a series-parallel shipbuilding model. The most direct problem brought about by this model is that the entire ship After the water is released from the dock, the floating of the half-ship and the positioning control after the second landing of the pier, due to the difference in the construction batch, the working conditions of the floating and pier of the half-ship are also divided into: one is that the half-ship does not need displaceme

Abstract

The invention relates to a general positioning method for half-ship refloating and pier falling. The method consists of a positioning guide device, a stabilizer device, a limit device and a series ofweight, cable and precision control schemes to form a set of more versatile positioning methods for the ship to refloat and piers to fall., t, the method is not only applicable to the refloating and piers falling of half-ship products, but also applicable to the secondary docking and lifting piers of various offshore platforms. The invention effectively solves the problem of how to safely and efficiently complete the floating and lifting and the secondary lifting piers of ships under various working conditions, reduces the deformation of the ship hull and shortens the docking period.

Description

technical field [0001] The invention relates to the technical field of manufacturing ships and marine products, in particular to a half-ship positioning method for floating and falling pier. Background technique [0002] With the increase of major shipbuilding projects under construction, the pressure on the construction of docks continues to increase. In order to seek a higher utilization rate of the dock and shorten the construction period in the dock, the shipyard has optimized in many aspects, including adding the middle dock door of the dock, improving the reserve of the number of loading sections and loading efficiency, and maximizing the total group and unit modules, etc. etc. However, for the construction of large ships with different docking periods, in order to improve the utilization rate of the dock and ensure the undocking cycle of the ship, it is inevitable to adopt a series-parallel shipbuilding model. The most direct problem brought about by this model is tha...
