a) Where the ship’s length exceeds 100 m, the fore-and-aft static angle of inclination may be taken as 500/L degrees.
(where L = length of ship in metres)
b) Up to an inclination angle of 45 degrees, switches and controls are to remain in their last set position as no undesired
switching operations or operational changes may occur.
c) For ships carrying liquefied gases or chemicals the arrangement is to be such that the emergency power supply also re-
mains operable with the ship flooded to a final athwartships inclination up to 30 degrees.
