"Witryna7 lip 2024 · IMO started a revision of the first stability criteria in 2001, focusing on the need to update the coefficients of the weather criteria . This new criterion was revolutionary for that time; it involved the classification of failures into five failure modes at three different levels. " - Imo weather criterion

Witrynamodels used in these criteria frequently lead to inconsistency, i.e. stricter L2 than L1. A methodology is proposed to allow some controlled level of probability of inconsistency. Besides, the issue of integrity is raised: because L1 is based on the Weather Criterion, making L2 less restrictive than L1, as usually, may lead WitrynaEVALUATION OF THE IMO WEATHER-CRITERION FOR PASSENGER SHIPS BY DI- RECT CALCULATION OF CAPSIZING FREQUENCIES Tobias Blome, TU Hamburg- Harburg, Germany …
