Xu, S., Guedes Soares, C. e Teixeira, A. P. (2018), “Reliablity analysis of short term mooring tension of a semi-submersible system”, Proceedings of the ASME 2018 37th International Conference on Ocean, Offshore and Arctic Engineering (OMAE 2018), 17-22 Junho, Madrid, Espanha
A detail procedure to study mooring line strength reliability is presented. A fully coupled analysis is carried out to get the mooring tensions of a deep water semi-submersible floating systems operated in 100 year wave condition in South China Sea. The ACER method is applied to predict the 3h extreme mooring tension, and the results are validated by global maximum method. The hydrodynamic sampling points are generated by Latin Hypercube Sampling technique. The 3h extreme mooring tension is calculated by the ACER method with 10 minutes fully coupled dynamic simulation for each sampling point. The Kriging meta model method is trained to predict 3h mooring extreme tension under the effects of random hydrodynamic drag coefficients. A reliability analysis is carried out by implementing Monte Carlo simulation with the random hydrodynamic drag coefficients and mooring breaking strength considered.
