3. Stability

3.1 Criteria of Stability Calculation

(1) Stability calculation is to be in accordance with following conditions.

(A) The position of center of gravity of dock gate is to be obtained from the results of inclin- ing test.

(B) The free surface effect of liquid tanks is to be considered.

(2) Further details other than above, Pt 1, Annex 1-2 of Guidance relating to the Rules is to be applied to stability calculation.

3.2 Metacentric Height, ÄB

The initial metacentric height ÄB is not to be less than 1.0 m for the each following condition.

(1) Lifted condition with minimum draft

(2) Each lifted condition taking into account the tidal difference

3.3 Stability Information

Stability Information is to include following.

(1) Capacity and the location of center of compartments and tanks, and the moment of inertia of free surface to be presented in numerical tables or curves

(2) Hydrostatic curves or numerical tables

(3) Other data deemed necessary by the Society.
