2 Potential downflooding openings - (resolution MSC.26(60))

  2.1 Where the location of openings can lead to significant downflooding, they should be taken properly into account when carrying out the A/Amax calculations. Their status should be identified by an on-board survey and the details of such openings should be updated, if necessary, on the damage control plan.

  2.2 When carrying out the calculations to establish the A/Amax ratio, such downflooding openings should be assumed closed watertight, or weathertight, as appropriate.

  2.3 In order that a contribution to the `A' value can be made, such downflooding openings should be closed to a credible degree of tightness. Where internal doors are shown to be situated above both the intermediate and final waterlines after assumed damage, they are not required to be strictly watertight.
