Incorporating the current condition of the assets into the process, the probability of failure subject to the various environmental hazards was thoroughly studied to check conformance against industry acceptable limits using both design level and ultimate strength approaches...

... are separately predicted by completely independent RNN-LSTM models based on different sets of real-time drilling parameters. These models run as ensemble learning models to continuously predict influx indicators. Then, the prediction results will be quantified, and the probability of kicks will be calculated...

... of this is that the extreme wave-driven vessel excursions will be large in comparison with the average motion. A marine operation can only be carried out provided the critical variables of response stay below given limits with a sufficiently large probability. To estimate probabilities of limit non-exceedance, simulation...
