CHAPTER II-1 CONSTRUCTION — SUBDIVISION AND STABILITY, MACHINERY AND ELECTRICAL INSTALLATIONS
PART B INTACT STABILITY, SUBDIVISION AND DAMAGE STABILITY
Part B-2 Ships constructed before 1 January 2009
18 Stability information (R 22)
NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:
.1Every passenger ship, shall be inclined upon its completion and the elements of its stability determined. The master shall be supplied with such information, approved by the Administration of the flag State, as is necessary to enable him by rapid and simple processes to obtain accurate guidance as to the stability of the ship under varying conditions of service.
.2Where any alterations are made to a ship so as to affect materially the stability information supplied to the master, amended stability information shall be provided. If necessary the ship shall be re-inclined.
.3At periodical intervals not exceeding five years, a lightweight survey shall be carried out to verify any changes in the light ship displacement and longitudinal centre of gravity. The ship shall be re-inclined whenever, in comparison with the approved stability information, a deviation from the lightship displacement exceeding 2 % or a deviation of the longitudinal centre of gravity exceeding 1 % of the length of the ship is found or anticipated.
.4The Administration of the flag State may allow the inclining test of an individual 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 Administration of the flag State that reliable stability information for the exempted ship can be obtained from such basic data. Reference is made to MSC/Circ.1158.
.5When an accurate inclining is not practical, the lightweight displacement and centre of gravity shall be determined by a lightweight survey and accurate calculation. Reference is made to the information contained in Regulation 2.7 in the in the High Speed Craft Code 2000.”
