Abstract

Firstly, ANSYS software was adopted in modeling and meshing. And then the characteristic of motion response to regular waves has been analyzed in frequency domain by using AQWA-LINE. Considering the coupling effect between FPSO and its mooring lines, time history of mooring line tension in time domain has been attained by utilizing AQWA-DRIFT. Then dichotomy was used to search the secure incident angels of joint wave, wind and current which meet both the tension limitations and the motion limitations. And investigations have been made on the impact that the total length of each mooring line has on the maximum tension of mooring line.
