2 Definition of the terms and symbols used

  • Note: Subscripts 1, 2, 3 etc., below relate to the appropriate spaces in figures A-9 to A-12. For example:

  • C123 is a space comprising compartments C1, C2, C3;

  • C345 is a space comprising compartments C3, C4, C5;

  • s67 is the factor which accounts for the probability of survival after flooding compartments C6, C7, etc.

→ indicates the direction of assumed side damage.
dA gives the contribution to the attained index of the damage case being considered.
d is the draught being considered and is either dl, or dp (i.e. deepest subdivision load line or partial load line).
H1, H2 are the first and second horizontal subdivisions, respectively, viewed from the waterline upwards.
HU is the uppermost boundary which limits the vertical extent of flooding.
v1, v2 are the first and second longitudinal subdivisions, respectively, viewed from the side where damage is assumed.
C indicates a compartment bounded on all sides by watertight boundaries.
C123 indicates a space which, for the purpose of assumed flooding, is treated as a single space comprising compartments C1, C2 and C3.
• indicates a compartment which lies outside the limits prescribed for all the damage scenarios (i.e. the compartment remains intact for all assumed damage cases) except for possible cross-flooding.
pl (regulation 25-5.1) is the factor which accounts for the probability that the longitudinal extent of damage does not exceed the length of the damage zone (length l) being considered.
