... failure data, maintenance, and operational parameters of mooring line components installed between 1992 and 2021. Life data analysis was used to evaluate how the failure probability evolved with the lifetime. Therefore, the Weibull parameters of each mooring line component were estimated. The strategy...

... calculations provide an estimate of failure probability for static conditions. It is not straightforward to relate the calculated timeless failure probability to a failure frequency. Nadim et al (2003) and Lacasse and Nadim (2007) developed several ideas for quantifying the annual probability of slope...

As the collapse of a marine platform, due to fatigue, is viewed as the progressive failure of a set of joints, a process of assumed incremental damage is used to simulate the structure deterioration. Consequently...
