Research On Automatic Leveling System Of Mobile Platform In Shallow Sea

Mobile offshore platform is a large and high-end equipment in offshore construction,it can effectively explore and exploit marine natural resources.With the increasing construction of foundation projects in shallow sea areas,such as the construction of artificial islands and wharfs.Because the traditional marine mobile platform relies on tugboats to move in the sea,its mobility is affected by shallow sea environmental factors,such as water depth,and the cost is high.Therefore,it is urgent to develop a new type of mobile platform to solve the construction difficulties in shallow sea areas.Firstly,through the specific analysis of the shallow sea environment,the environmental factors that may affect the operation of the new shallow sea mobile platform are studied.The structure and hydraulic system of the shallow sea mobile platform are designed.The four-point automatic leveling method is used to make the designed shallow sea mobile platform meet the operation requirements of keeping the working platform leveling and keeping a certain safe distance from the sea level in the process of stationary and walking.The automatic leveling system becomes the key technology of the new shallow sea mobile platform.Secondly,the design of four-point support leveling system is simulated and analyzed by using fuzzy-PID control method.The performance of position error leveling scheme and angle error leveling scheme is studied and compared to the actual working conditions.The leveling strategy of the new shallow sea mobile platform is synthetically designed.Finally,the automatic leveling experiment of the mobile platform is carried out.The experimental results show that the leveling performance of the automatic leveling system of the mobile platform in the process of stationary and walking meets the requirements,and verifies the safety and reliability of the mobile platform in shallow sea operation.
