Abstract

The FPSO-related patents reported on platform PatSnap, are analyzed. The evolution path of the patented technology is explored in terms of time situation, regional distribution, important applicants, and the category of core technology. The research shows that the technical development of FPSO ship production system has the characteristics of regional concentration and hotspot concentration; The developments are found having mainly focused on three fields: the treatment of oil, gas, and water, production equipment and storage devices, especially the topics concerning cooling, recycling, and reliquefaction treatment of gas vapor, support device of superstructure, and tank strength. Among them, the related technology of evaporated gas treatment system and tank structure design has attracted special attentions.
