Damage Stability - B/5 Line Assumption
Damage penetration depth per classical SOLAS II-1 deterministic rule - horizontal penetration ≤ B/5 measured inboard from the moulded side.
B/5 assumed penetration
5.60m
Formula, assumptions, and limits
Applies to pre-2009 SOLAS method. Probabilistic method uses statistical penetration from LMS records. B/5 still used for fuel-oil tank and side-tank protection in oil tankers (MARPOL Annex I Reg. 19).
