Garbatov, Y. and Guedes Soares, C. (2016), “Reliability assessment of a container ship subjected to asymmetrical bending”, 13h International Symposium on Practical Design of Ships and Other Floating Structures (PRADS 2016), 4-8 September, Copenhagen, Denmark
The objective of this work is to analyse the structural reliability of a container ship subjected to asymmetrical bending. The ultimate load carrying capacity is estimated based on the Finite Element Method. The strength assessment accounts for the effect of the midship section neutral axis translation and rotation of a non-damaged container ship due to asymmetrical bending load. The ultimate longitudinal strength, still water and wave-induced bending moments are considered as random variables and the uncertainties resulted from the use of different methods in the strength and load assessment are also accounted for. A sensitivity analysis is performed, identifying the most important parameters for structural reliability of a non-damaged container ship subjected to asymmetrical bending. The reliability of the container ship during the service life is estimated to account for the time spend in full, partial and harbour loading conditions and considering the asymmetrical bending load as a consequence of different angles of heel in hogging and sagging.
