Regulation 15

Every ship shall undergo an inclining test upon its completion and the actual displacement and position of the centre of gravity shall be determined for the light ship condition. (2) Where alterations are made to a ship affecting its light ship condition and the position of the centre of gravity, the ship shall, if the Certifying Authority considers this necessary, be reinclined and the stability information amended. (3) The Certifying Authority may allow the inclining test of a ship to be dispensed with provided basic stability data are available from the inclining test of a sister ship and it is shown to the satisfaction of the Certifying Authority that reliable stability information for that ship can be obtained from such basic data. (4) The Certifying Authority may also allow the inclining test of a cargo ship or a class of ships, especially designed for the carriage of liquids or ore in bulk, to be dispensed with when reference to existing data for similar ships clearly indicates that due to ship proportions and arrangements more than sufficient metacentric height will be available in all probable loading conditions.
