This PhD focuses on the characterization of the materials of the insulating coating of offshore pipelines as well as the welding made between the two semi-crystalline polymers of the coating at the junction of two consecutives pipes.The important thickness of the coating induces heterogeneous heating and cooling rates during the welding process. Those rates have been characterized through the implementation of thermal sensors during the industrial process. A simulation model of the different steps of the welding process is consistent with the experimental results. This simulation gives access to the thermal fields in the entire pipe and especially in the welding zone.This study allows us to characterize the two welded materials during their...
