Aborts and Contingencies
Even if a Passage Plan has been well planned and conducted, there may be some cases in restricted waters when the Passage Plan will have to be abandoned due to change in circumstances (like equipment failure, port instructions etc)
The Abort Point is a position to be marked on the charted course where the ship may abandon her passage and be able to return (or hold position safely).
Take care when marking an abort. At the abort position, there should be sufficient sea room for the ship to undertake any of the following maneuvers in safety:
Turn around Stop in safe waters Anchor
Once this point is passed , the ship is committed and must continue on the passage.
Contingency Planning by the Master shall be done in advance which may include Alternative routes, Safe anchorages, Waiting areas, Emergency berth etc., after passing the Abort Point.
