Document Type and Number:
WIPO Patent Application WO/2023/083123
Kind Code:
A1
Abstract:
Provided is a leveling control system in the offshore mounting of a three-bucket jacket foundation, comprising: a position and posture monitoring system mounted on the top of the three-bucket jacket foundation and used for monitoring GPS coordinates and inclination information of the top of the three-bucket jacket foundation in real time; a master station control system for performing analysis processing on the GPS coordinates and the inclination information and outputting a corresponding control signal; and an underwater action system for controlling corresponding actions of action components of the three-bucket jacket foundation according to the control signal, so as to separately control pressure differences between the interiors and exteriors of three buckets of the three-bucket jacket foundation. Further provided is a leveling control method based on the leveling control system. It can be ensured that the degree of inclination of the top surface of a jacket does not exceeds a design value during the whole process of sinking, such that the safety and success rate of construction are ensured.
