THE ANALYSIS AND STUDY OF MODULE STOOL OF FPSO IN SEVERE SEA STATE

摘要

This paper, taking the FPSOs of 150000t dwt "Nanhai March" and "Ocean Petrol 111" as examples, which are designed by MARIC, in type of inner turret, serving and permanently moored in the violent typhoon sea area, studies the deformation of the hull girder, compares different support structure stress response of the FPSOs under wind, wave and current loads, analyzes the requirements of fire protection, pipe line arrangement and safe passage, then presents a new type of module stool structure of the FPSO, which suits service in severe sea state and can endure violent typhoon with the probability of 100 year occurrence.
