Guedes Soares, C. and Garbatov, Y. (1996), “Fatigue Reliability of Containership Hull Girders Considering Maintenance Actions, Proceedings of the First International Conference on Marine Industry (MARIND’96), Varna, Bulgaria, Vol. I, pp. 151-166
A formulation is presented for the assessment of the reliability of a ship hull regarding fatigue failure of the longitudinal members. The model allows for the existence of multiple cracks and its accounts for the crack growth process. The midship section modulus is described by a function of time and the resulting reliability estimates with respect to several parameters is also studied. The formulation has been applied to three containerships. Their fatigue reliability is predicted by a time variant formulation and the effects of maintenance actions in updating the reliability assessment are shown.
