An offshore four-tube foundation type wind power complete machine installation vessel and its one-step construction method

Abstract

The invention belongs to the technical field of ocean vessels, and discloses a maritime four-cylindrical-foundation type wind-power complete machine installation vessel and a one-step type construction method thereof. The installation vessel comprises a hull, a tower, hoisting equipment, a locking, fixing and holding device, a fine adjustment and righting device, an anti-collision device, an anchor casting positioning device and a control driving cab; three-direction constraint of four cylindrical bases and buoyancy are achieved through the hull, and buoyancy is transmitted; hoisting operation during sinking and leveling is conducted through the tower and the hoisting equipment; the four cylindrical bases and a fan tower drum are connected with the hull through the locking, fixing and holding device so that the buoyancy transmitting effect can be achieved; the hull is protected by the anti-collision device; the fine adjustment and righting device is used for leveling and ensuring the structure stability; the anchor casting positioning device is used for positioning the hull; and the control driving cab has the functions of both driving and comprehensive regulation. According to the maritime four-cylindrical-foundation type wind-power complete machine installation vessel and the one-step type construction method thereof, the functions of one-step installation, towing, positioning, leveling, immersion and the like can be achieved, the machine installation efficiency is improved, the installation cost is reduced, and the sea condition influence is small; and the long construction period of a split type installation mode 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 four-cylinder basic wind power complete machine, which realizes the overall assembly, grid-connected debugging and offshore four-cylinder wind power complete machine at the wharf. 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 construction of offsho...
