Technical Field

The utility model relates to an offshore wind power technology field, concretely relates to sit end ship.

Background

At the present stage, China vigorously develops offshore wind power construction, and the water level of part of construction positions is deep or even extremely shallow (the average water depth is less than 3 m). For a shallow water machine position, because the traditional wind power installation platform has deep draught, the shallow water machine position is difficult to enter for construction operation when the shallow water machine position is tide. The current mainstream solution is to use a shallow draft barge to be matched with a crawler crane to carry out shallow water machine position fan hoisting operation, the shallow draft barge enters the machine position when the shallow draft barge is still wet, and the 'static-to-static' hoisting operation required by fan installation is realized in a bottom-sitting mode.
