dead ship condition;
•
following/stern quartering seas associated with matters related to stability variation in waves, in particular reduced righting levers of a ship situated on a wave crest;
•
parametric resonance, including consideration of matters related to large accelerations and loads on cargo and stability variation in waves;
•
broaching including consideration of matters related to maneuverability and course keeping ability as they affect stability;
•
excessive accelerations.Moreover the new generation intact stability criteria will be structured in three levels:
•
Vulnerability 1st level;
•
Vulnerability 2nd level;
•
Direct assessment.
