2. If the significant height of the swell (hs) in the affected area is 1.5 m or less, no additional water is accumulated on the damaged roam bridge. If the significant swell height in the area is 4.0 m or greater, the height of the assumed accumulated water is the value calculated in accordance with paragraph 1.1. Intermediate values to be determined by linear interpolation (see figure 3). (e) nominal and measured wave spectra (near the wave machine or near the model) 3.3 At least 5 experiments should be conducted for each peak period. The duration of the tests for each race must be long enough to reach a stationary state, but must be performed full-time for no less than 30 minutes. For each test, another wave-making train should be used. The JONSWAP spectrum that it is supposed to use, as described, limited seas and duration, which correspond to the majority of conditions worldwide. In this context, it is important not only to check the peak time of the corrugated train, but also to check the zero crossing time.
3.1 The model is expected to be subject to a long, irregular maritime route defined by the JONSWAP spectrum, with a significant swell height defined at point 1.3 of the stability requirements and presenting a peak improvement factor (and the peak Tp period as follows: 1). The amount of water-on-bridge assumed cumulative can be reduced in addition to any reduction provided in paragraph 1.1 for operations in geographically delineated regulated areas, these areas are designated based on the significant swell height (hs) that defines the area in accordance with Article 5. (23) SOLAS 90 stability standards provide a level of safety equivalent to that of the specific stability requirements set out in this Directive for vessels operating in maritime areas with a significant swell height of 1.5 m or less. Barriers of a height lower than the one mentioned above may be accepted if type tests are conducted in accordance with Part II of this schedule to confirm that the alternative design ensures an appropriate level of survival. The height of the bulkhead/barrier must be careful, so that the altitude must be sufficient to avoid incremental flooding in the required stability zone. This area should not be affected by modeling tests. 3. The hw height remains constant, which is why the amount of water added is variable, as it depends on the angle of heeling and whether or not the edge of the ceiling is submerged at a heeling angle (see figure 4).
It should be noted that the supposed permeability of the car bridge locations must be taken into account as 90% (MSC/Circ.649) while other supposedly flooded spaces are those prescribed by SOLAS.
