What are the corrective actions for angle of loll and list?

  1. Check that port and starboard listing moments are the same.

(By verifying tank soundings and checking for cargo shift it should be possible to account for any listing moments that may cause the ship to be in a listed situation. If it is calculated that there are no net listing moments then a case of instability may be assumed and the ship will be lying at an angle of loll. Recalculation of the ship’s effective KG should also be undertaken to verify the ship’s GM.)

  1. Check for slack tanks

(In carrying out (2) above it should also be evident if there are excessive free surface moments causing a loss of GM sufficient enough to make the ship unstable. In this case a loll situation may be confirmed.)
