the lowest point of the deck edge of the damaged compartment of the ro-ro deck; or
when the deck edge of the damaged compartment is submerged then the calculation is based on a fixed height above the still water surface at all heel and trim angles;
as follows:
0,5 m if the residual freeboard (fr) is 0,3 m or less,
0,0 m if the residual freeboard (fr) is 2,0 m or more, and
intermediate values to be determined by linear interpolation, if the residual freeboard (fr) is 0,3 m or more but less than 2,0 m,
where the residual freeboard (fr) is the minimum distance between the damaged ro-ro deck and the final waterline at the location of the damage in the damage case being considered without taking into account the effect of the volume of assumed accumulated water on the damaged ro-ro deck,
0,0 m if the significant wave height (hs) defining the area concerned is 1,5 m or less;
the value determined in accordance with paragraph 1.1 if the significant wave height (hs) defining the area concerned is 4,0 m or above;
intermediate values to be determined by linear interpolation if the significant wave height (hs) defining the area concerned is 1,5 m or more but less than 4,0 m,
provided that the following conditions are fulfilled:
the flag State administration is satisfied that the defined area is represented by the significant wave height (hs) which is not exceeded with a probability of more than 10 %; and
the area of operation and, if applicable, the part of the year for which a certain value of the significant wave height (hs) has been established are entered on the certificates.
