  Σ k : Sum of friction coefficients in the considered cross-flooding arrangement.

  S (m2) : Cross-section area of the cross-flooding pipe or duct. If the cross-section area is not circular, then:

  • where:

    • A = actual cross-section area

    • p = actual cross-section perimeter

  θ 0(°) : Angle before commencement of cross-flooding. The cross-flooding device may be assumed to be full or empty dependent on its arrangement and internal volume (see figure 1(b) in appendix 1).

  θf (°) : Heel angle at final equilibrium ( θf ≤ θ ).

  θ(°) : Any angle of heel between the commencement of cross-flooding and the final equilibrium at a given time.

  Wf (m 3) : Volume of water which is used to bring the ship from commencement of cross-flooding θ 0 to final equilibrium θf .

  Wθ (m 3) : Volume of water which is used to bring the ship from any angle of heel θ to the final equilibrium θf .

  H 0(m) : Head of water before commencement of cross-flooding, with the same assumption as for θ 0 .

  Hθ (m) : Head of water when any angle of heel θ is achieved.

  hf (m) : Final head of water after cross-flooding ( hf = 0, when the level inside the equalizing compartment is equal to the free level of the sea).

  g (m/s2) : The acceleration due to gravity (9.81 m/s2).
