Problems solved by technology
[0004] As far as construction in tidal flat areas is concerned, in extremely shallow areas (high tide water depth 0-1.0m), temporary roads can be built to gradually advance from land to the work site, and construction platforms can be built on the spot; in deep water areas (high tide water depth 5m) Above), since there is basically no exposed beach at the lowest tide level, the method of small and medium-sized floating cranes can be used; only in shallow water areas (high tide water depth 1.0m ~ 5.0m), construction is more difficult

Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] The specific steps for hoisting with shallow water barge and crawler crane are as follows:
[0025] 1) First carry out structural modification and load test on the barge: ① Temporarily fix the crawler crane that meets the hoisting capacity on the barge deck, and install a steel or wooden structure cushion between the crawler crane and the barge deck; The maximum hoisting load test is carried out under sea conditions, so that the strength of the hull structure is good during loading, and it has sufficient buoyancy after unloading; ③ Set up a water storage tank on the barge and install a pump.
[0026] 2) Move the wind turbine components to the ship, including the tower, engine room, hub and blades, and place them on the barge deck.
[0027] 3) In the vicinity of the wind turbine installation foundation in the tidal flat area, set several positi...

The invention relates to an operation method for lifting a fan for a barge in a shoal area, which comprises the following steps of: 1) performing barge reformation and load tests, including temporarily fixing a crawler crane on the barge and arranging a water storage bin and a suction pump; 2) carrying fan components to the barge; 3) sinking a positioning pile near the foundation of the fan, dragging the barge to an area enclosing by the positioning pile by utilizing a tugboat during flood tide, and anchoring the barge in place; 4) storing water in the water storage bin of the barge for ballast to make the barge properly bottomed; 5) after the barge is stabilized, beginning the lifting operation: a, arranging a tower; b, arranging a hub and two blades; and c, arranging the last one blade;6) after the primary construction operation, pulling the barge near the foundation of another fan by using the tugboat during flood tide; and 7) finishing arrangement of all fans in the primary load, unmooring the barge during the next flood tide to load the next batch of fan components shoreside, and repeating the operation. The operation method is particularly suitable for construction operation in a shallow water area of the shoal area.
Description
technical field [0001] The invention relates to a method for hoisting at sea, in particular to an operation method for hoisting a wind turbine by a barge in a tidal flat area. Background technique [0002] Coastal tidal flats are both land and part of the sea, and are called "intertidal zones" in geomorphology. Due to the effects of tides and wind tides, the tidal flats are sometimes submerged by water and sometimes exposed to the water surface. Tidal flats not only contain various minerals, but also important land resources. Common tidal flat projects include: seawall cofferdams, breakwaters, wharf trestles, artificial islands, jetty sea access roads, submarine pipelines, jacket platforms, sea-crossing bridges, etc. Since coastal tidal flats and offshore wind energy are greater than those in inland areas, the construction of tidal flat wind farms has also become an important means of energy utilization. [0003] However, due to the landform characteristics of the tidal f...
