Guideline

 When ballasting, necessary to meet the stability requirements of chapter VI, cannot be accomplished at the loading berth any proposal to defer ballasting should be approved by the port authority. However, at no time during the ballasting operation should the GM corrected for a free liquid surface, including the free surface in the ballast tank which is in the process of being filled, be less than 0.3 m. Similarly, deballasting at the end of a voyage should be subject to the same requirement.
