2. Conditions of inclinations

All machinery, components and systems essential to the safe operation of a unit are to be designed to operate under the following static conditions of inclination :

(1) when column-stabilized units are upright and inclined to an angle up to 15° in any direction :

(2) when ship type units are upright and level trim and when inclined to an angle of list up to 15° either way and simultaneously trimmed to an angle up to 5° by the bow or stern.

The Society may permit or require deviations from these angles, in consideration of the type, size and service conditions of the unit.
