3 Verdrag inzake stabiliteitsvereisten voor passagiersschepen die geregelde internationale lijndiensten van en naar havens in Noord-West-Europa en de Baltische Zee onderhouden

Model test method

3.1 The model should be subjected to a long-crested irregular seaway defined by the JONSWAP spectrum with a significant wave height Hs, defined in paragraph 1.3 of the stability requirements and having peak enhancement factor γ and peak period Tp as follows:

.1. Tp = 4√Hs with γ = 3.3; and

.2. Tp equal to the roll resonant period for the damaged ship without water on deck at the specified loading condition but not higher than 6√Hs and with γ = 1.

3.2 The model should be free to drift and placed in beam seas (90° heading) with the damage hole facing the oncoming waves. The model should not be restrained in a manner to resist capsize. If the ship is upright in flooded condition, 1° of heel towards the damage should be given.

3.3 At least 5 (five) experiments for each peak period should be carried out. The test period for each run shall be of a duration such that a stationary state had been reached but should be run for not less than 30 min in full-scale time. A different wave realization train should be used for each test.

3.4 If none of the experiments result in final inclination towards the damage, the experiments should be repeated with 5 runs at each of the two specified wave conditions or, alternatively, the model should be given an additional 1° angle of heel towards the damage and the experiment repeated with 2 runs at each of the two specified wave conditions. The purpose of these additional experiments is to demonstrate, in the best possible way, survival capability against capsize in both directions.

3.5 The tests are to be carried out for the following damage cases:

.1. the worst damage case with regard to the area under the GZ curve according to SOLAS; and

.2. the worst midship damage case with regard to residual freeboard in the midship area if required by 2.1.
