Garbatov, Y. and Guedes Soares, C. (2001), “Cost and Reliability Based Strategies for Fatigue Maintenance Planning of Floating Structures", Reliability Engineering and System Safety, Vol 73, Issue 3, pp. 293-301

Floating Structures are designed in such way that the appearance of fatigue failures cannot be avoided, implying the need for inspections during their life. Their maintenance has to be planned from an economic point of view so as to minimize maintenance costs but satisfiyng a minimum reliability level. A method is proposed to quantify the repair costs resulting of different reliability-based maintenance strategies. As an application of this approach a side shell structure typical of a floating production unit is analysed and the influence of different parameter with respect to the repair costs is also studied here.
