On-sea three-barrel foundation type wind-electricity overall machine installation ship and single-step construction method thereof

Abstract

The invention belongs to the technical field of marine ships and discloses an on-sea three-barrel foundation type wind-electricity overall machine installation ship and a single-step construction method thereof. The on-sea three-barrel foundation type wind-electricity overall machine installation ship comprises a ship body, a tower frame, a hoisting device, a locking cohesion device, a fine adjusting righting device, an anti-collision device, an anchor positioning device and a control driving cab. The ship body achieves three-directional constraint for three barrel-shaped foundations and transfers buoyancy. The tower frame and the hoisting device provide hoisting operation in the sinking and leveling processes. The locking cohesion device enables the three barrel foundations and a draught fan tower barrel to be connected with the ship body and transfers the buoyancy effect. The anti-collision device protects the ship body, and the fine adjusting righting device is responsible for leveling so as to ensure structural stability. The anchor positioning device positions the ship body, and the control driving cab has the driving and comprehensive adjusting and controlling functions. According to the on-sea three-barrel foundation type wind-electricity overall machine installation ship and the single-step construction method thereof, the functions such as single-step installation, towage, positioning, leveling, sinking can be achieved; machine installation efficiency is improved, installation cost is reduced, and the influence of the sea condition is small; and the long construction period of split type installation is shortened, the construction difficulty is lowered, and the construction process is simplified.

Description

technical field [0001] The invention belongs to the technical field of ocean ships, and in particular relates to a transportation and installation equipment for an offshore three-cylinder basic wind power machine, which realizes the overall assembly of the offshore three-cylinder wind power machine at the wharf, grid-connected debugging and offshore installation. An integrated construction operation method of transportation, fixed-point balancing, and sinking installation. Background technique [0002] Wind energy is a kind of usable energy provided to human beings due to air flow. It has the characteristics of wide distribution and huge total amount, and it has quickly become a new direction of energy development in various countries. Utilizing wind energy to generate electricity is the main way to develop wind energy. Wind farms can be divided into two types: onshore wind power and offshore wind power according to their location. From a technical perspective, the construct...
