| (a) | a ship security plan for a South African regulated ship (the existing plan) is in force; and |
| (b) | the Authority is no longer satisfied that the existing plan adequately addresses the relevant requirements under Division 3— |
| (i) | because there is a change in the circumstances that relate to maritime transport security; or |

the Authority may, by written notice to the ship operator for the ship, direct the ship operator to give the Authority a revised plan under regulation 69.
| (2) | The notice must specify the period within which the revised plan must be given. |
