Fatigue Assessment of FPSO

Fatigue of ship structures is an important damage phenomenon.Especially when high strength steel was widely used in ship structures, the fatigue damage of ship structures became more and more important. The procedure of fatigue analysis for FPSO is detailedly discussed in this paper according to FPSO's structural property and especial working condition, which includes the determination of fatigue check area of FPSO, wave load prediction and fatigue calculation method of main check position.
