Subdivision - s-Factor (Survival Probability)
Probability of survival s in a damage case based on residual GZ curve - A = Σ (p · s · v) for attained subdivision index.
Factor s
0.750 -
Formula, assumptions, and limits
Clip at s = 1. Equilibrium heel > 15° → s = 0. Ro-ro passenger / passenger ships use stricter curves (SOLAS II-1 Reg. 7-2 amendments 2020).
