Study On Thin Plate Deformation Control Technology Of Offshore Engineering Living Quarter

With the exploitation and utilization of marine resources,more and more countries pay attention to offshore engineering platform.As an important part of the platform,the superstructure construction process is paid more and more attention to because of its thin steel plate and easy deformation.Thin plate deformation control is an important technical mark to ensure the construction quality of the platform,reduce the construction cost,improve the customer satisfaction,and reflect the construction management level of the enterprise.In this paper,taking the living building of CIMC Raffles semi-submersible drilling platform as the research object,through the thin plate deformation problem in the process of building the GM4D-270 semi-submersible platform superstucture under construction,the causes of deformation in each process stage are analyzed.The process method of deformation control is made.Firstly,in the four main technological stages of steel plate cutting,panel welding,block welding and block erection in the construction of superstructure,tracking measurement and recording are carried out,and the deformation problems in each stage are found.Secondly,analyze the causes of deformation,find out the leading factors leading to all kinds of deformation,formulate specific control measures and corresponding process treatment methods;Finally,the technology is improved and applied successfully in the follow-up platform construction,and the effect is quantitatively analyzed and perfected and summarized to improve the effectiveness and rationality of the thin plate deformation control process.Based on the analysis of the influencing factors and construction difficulties of the thin plate deformation of the main superstructure of offshore engineering platform,this paper puts forward the procedure of thin plate deformation control,which is of direct guiding significance to the improvement and enhancement of the thin plate deformation control of the offshore engineering platform.It also has reference value for the construction of thin plate in the same industry.
