Problems solved by technology

There are water structures downstream of the channel. Under a certain water flow load, if the mooring positioning system fails, the engineering ship will lose control, which will cause a huge impact on the downstream water structures
At the same time, when the engineering ship is operating, other auxiliary ships only need to pass back and forth for auxiliary operations, and the existing mooring methods will affect the passage of ships

Embodiment Construction

[0018] The method steps of the present invention are illustrated by the following figures.

[0019] Such as figure 1 , figure 2 Shown is a schematic diagram of the layout of the ship mooring positioning structure of the present invention. Wire rope 1, 2, anchor 3, shore fixing device 4, winch 5, vertical shaft fairlead 6, vertical fairlead pulley 7, six-roller fairlead 8, anchor chain 9.

[0020] The winch 5 and the vertical shaft fairlead 6 are placed below the hull deck 12 . The winch 5 is fixed in the fore and aft winch compartment of the ship through the base; the vertical shaft fairlead 6 is fixed in the bulkhead in the fore and aft winch compartment through the base; the vertical fairlead pulley 7 and the six-roller fairlead 8 are fixed in the ship through the base on deck 12.

[0021] The steel wire rope 1 passes through the winch 5's own cable arrangement, reaches the vertical shaft fairlead 6, goes vertically upward to the vertical fairlead pulley 7 of the main d...

Abstract

The invention provides a ship mooring and positioning method. Four cement piers are used for replacing existing anchors and placed underwater through steel wire ropes. Steel wire ropes on upstream underwater anchors are fixed to the shoreside, wherein the fixed points are close to the lowest water level to the greatest extent, and an anchor moored positioning winch with a constant tension function is used for adjusting the tension of the steel wire ropes. The ship mooring and positioning method meets the mooring requirement of fixed point operation in a narrow channel with obstacles on the two sides, does not affect navigation of an original river channel or proceeding of follow-up potential associated engineer operation, can bear a large wind load and current load, and can guarantee that no impact on nearby buildings on water is caused when a system partly loses efficacy. A ship can still operate normally even if the height of water is large.

Description

technical field [0001] The invention relates to a ship mooring positioning method, which is particularly suitable for a ship mooring system for fixed-point operations in deep water and narrow channels. [0002] Background technique [0003] For surface ships (such as engineering ships, test ships, and barges) that need to operate at fixed points in deep water and narrow channels, the conventional anchoring scheme is to use a winch to retract and release the anchor through the anchor chain. According to the water depth of different operating points, the anchor Sinks to the bottom of the water and grabs the soil to achieve positioning. However, in special waters, such as narrow waterways, complex underwater topography and geology, large water level drop, and water structures around the waters, if the conventional anchoring scheme is used to achieve positioning by dropping anchors, it is impossible to achieve positioning under complex underwater terrain. Grasp the anchor, and...
