Note
Once a loll situation is confirmed only ever fill one tank at a time. Always start by filling the low side tank first.
The angle of loll may initially worsen because the introduced free surfaces when initially starting to fill the tank may cause a greater rise of G than the fall of G caused by the added bottom weight. Hence the importance of filling small tanks first. If there is any doubt as to whether the ship is lolled or listed, always initially assume it is a lolled situation and take appropriate action, monitoring the situation carefully.
When correcting a list it is sufficient to shift a weight to the high side. This may be Achieved by shifting weights on deck or by transferring ballast from a listed side tank to a high side tank. Alternatively, excess ballast from the listed side (possibly low down in the ship) may be discharged or a low tank on the high side should be filled.
To treat a loll situation in the same way as for list would have disastrous consequences for reasons already explained!
