Study on Reverse Deformation Control of 154 000 DWT Shuttle Tanker in Erection Stage
This paper briefly expounds the precision control methods of several types of sections and blocks of the shuttle tanker during erection in dock in our factory,mainly containing double-bottom section positioning control,and section longitudinal and transverse wall positioning control,cargo tank Type"C"block positioning control,cargo tank lower side section positioning control and the rudder-shafting system positioning control.By studying the reverse deformation increment value of key processes,analyzing the actual erection assembly precision data,comparing and summarizing experience,and correcting the reverse deformation increment value,the precision design and management level are improved,and the best erection assembly effect is obtained,so as to provide the precision control experience and technology for the construction of the same type of tanker during erection and assembly.
