Construction method of offshore wind power construction ship based on DP module

Abstract

The invention relates to a construction method of an offshore wind power construction ship based on a DP module, which comprises the following steps of: 1, longitude and latitude coordinate information of a target position is input; 2, a DP control system closes the DP module and overturns and raises the DP module to the upper part of the sea surface; 3, a ship load control system starts a marinepropeller to drive a construction ship to reach the vicinity of the target position; 4, the DP control system overturns the DP module into seawater; 5, the DP control system adjusts the power output power value and the power output direction of the DP module arranged around the construction ship according to the information of the construction ship, the peripheral sea conditions and the like to stabilize the construction ship at the target position; 6, returning to the step 1 after the construction ship finishes the operation. According to the construction method, the construction efficiency is high and the operation precision is excellent.

Description

technical field [0001] The invention relates to a DP module positioning method, in particular to a construction method based on a DP module applied to an offshore wind power construction ship, and belongs to the technical field of offshore wind power construction. Background technique [0002] At present, in the process of offshore wind power construction operations, it is necessary to wait for the arrival of the time window before the normal construction operation (the sea conditions in the non-operation time window are bad, and the barge construction operation cannot be carried out normally), so the operation time is very precious; after the conventional construction ship goes to the destination It is necessary to stop the ship for anchoring and positioning (this operation process sometimes even takes several days in the deep sea area), and then set up the pile pipe at the target site and then go to the next destination to anchor again. The whole process requires multiple a...

The whole process requires multiple anchoring and anchoring, wasting a lot of precious time, reducing construction efficiency
