6 Acceptance of A/Amax calculations by the Administration - (resolution MSC.26(60))

  6.1 Where the A/Amax ratio, expressed as a percentage, for a ship is 95% or more, the Administration should accept that the requisite survivability standard for that ship has been achieved, and it should consequently be exempt from the upgrading process.

  6.2 The survivability of a ship may be upgraded step by step, in accordance with the scale outlined in regulation II-1/8.9 of the SOLAS convention adopted by resolution MSC.26(60). In such a case, a further A/Amax calculation should be performed, and then approved by the Administration, prior to the date specified by which the further upgrading should be completed.

  6.3 The residual stability standard to be achieved after upgrading should correspond to the modified SOLAS 90 stability criteria as expressed in regulation II-1/8.2.3.5 of the SOLAS Convention, adopted by resolution MSC.26(60).

  6.4 The Administration, on receiving the A/Amaxcalculation for a ship, should confirm that the calculation has been made according to the procedure outlined in MSC/Circular.574, together with any agreed interpretations, and, in particular, that specific approval is given for the A/Amax ratio.
