Abstract: The unconventional floating production storage and offloading unit (FPSO) with a special cylindrical structure has a large number of radial and divergent scantling, resulting in the tedious and time-consuming process of the positioning and modeling of these scantlings. A rapid modeling method that flexibly uses the engineering template techniques to establish the models of the cylindrical FPSO is proposed based on the CATIA's three-dimensional (3D) EXPERIENCE platform to rapidly establish the models of the cylindrical FPSO, to reduce the repetitive work in the modeling process, and to ensure the correlation among these scantlings, as well as to improve the modeling efficiency. This method is then compared with the direct rotation SSY method based on CATIA, and the general software modeling methods as FEMAP and NAPA designer. The results show that, compared with the following three methods: First, A local parent engineering template established based on the rapid modeling method of CATIA can solve the problem of tedious positioning of the radial scantlings, and implement the function of the rapid establishment of the cylinder models in batches with smaller model capacity. Secondly, The correlation and attribute inheritance among the batch rotating replicated plates and those among the scantlings can be ensured with the reduced repetitive work and improved modeling efficiency. Finally, When the model is adjusted in the later stage, only the structure needs to be altered is changed and the rest of the structure will be automatically adjusted because of the correlation among the internal structure of the model, thereby reducing the difficulty and workload of the model modification in the later stage.
