12 Conduct of inclining experiment

12.1 Heeling

12.1.1 Where the heeling is accomplished by the transfer of liquid under the provisions 2.3.4 of Annex 1 of the IS Code, details of arrangements for the transfer of liquids and the recording system to be used should be submitted to the Manager, Ship Inspection and Registration for acceptance at least 2 weeks prior to the experiment. When this method is used, strict attention must be paid to the following conditions:

(a) the tanks must be fully calibrated over the full range of soundings to be used during the experiment. The weight, transverse, vertical and longitudinal positions of the centre of gravity and the free surface moments of the contents are to be accurately established taking account of the trim and heel of the ship at inclining;

Note Rectangular tanks are preferred.

(b) the density of the liquid used for the heeling of the ship is to be determined using a hydrometer calibrated within the preceding 2 years if made of metal or 5 years if made of glass.

(c) the method used for transferring liquid from one tank to the other must be simple and direct, allowing for the transfer to be accomplished in a reasonable time with minimum leakage. Prior to undertaking the inclining experiment, the transfer system is to be purged to ensure that the system is working satisfactorily;

(d) a calibrated sight board must be set up in each tank to measure the liquid level;

Note The work of calculation is reduced and the accuracy increased where the sight boards are placed at the intersection of the longitudinal and transverse centres of the liquid surfaces. In a rectangular tank, the preferred position of the sight board would thus be at the vertical axis of the tank.

(e) safe access and adequate lighting of the sight boards must be provided to permit accurate liquid level readings to be taken; and

(f) where it is impossible or impracticable to measure accurately the liquid level in a tank using sight boards, the Manager, Ship Inspection and Registration may, on written application, accept the use of sounding tubes for measurement of liquid level.

12.2 Results of Inclining

12.2.1 In addition to the requirements of section 4.3 of Annex 1 to the IS Code, the following procedures are to be applied to the results of the inclining:

(a) for each pendulum, the ratio of applied heeling moment to the pendulum deflection (w.d/x) is to be calculated and recorded; and

(b) where any individual w.d/x value deviates by more than 5% from the average ratio for that pendulum, then the following must be checked and rectified if possible and appropriate:

(i) that the ship is still clear of the berth and that the moorings are still slack;

(ii) the pendulum readings, making sure that the pendulums are free to swing;

(iii) the value of the weight last moved and the distance through which it was moved;

(iv) that nothing aboard the ship has moved due to heeling; and

(v) that the ship is not aground.

Note For the purposes of 12.2:

Note: w means weight

Note: d means distance

Note: x means pendulum deflection

Note 2 A running average w.d/x ratio computed during the conduct of the inclination is generally a good early indicator of this type of problem.

12.2.2 Where it is found, after checking, that:

(a) the pendulum readings of the ship in the upright position are considerably erratic; or

(b) the pendulum deflexions are greater than might have been expected; or

(c) there is an inconsistency in the values of the pendulum deflexions for equal weight movements in opposite directions; or

(d) the ship appears to have an unexplained initial list that cannot be corrected

then the ship could have a negative GM value and therefore might be initially unstable. The inclining experiment must be immediately discontinued and the Manager, Ship Inspection and Registration advised.

Note For the purposes of 12.2.2 and 12.2.3, GM means the initial transverse metacentric height when one or more tank is slack, commonly known as the metacentric height.

12.2.3 If the reason for the w.d/x ratio deviation cannot be identified but none of the criteria in the preceding clause are triggered, then the Manager Ship Inspection and Registration may require all w.d/x ratios to be converted into values of measured GM and determine that the ‘as inclined’ GM value for the ship is to be the lower bound of a 95% confidence interval of the normal statistical distribution of those measured GM values.
