Transfer of Flag

When a vessel is transferred to Sierra Leone from another Contracting Government, the Conformance test report is considered valid in case that the ASP which carried out the conformance test is also either a recognized ASP or an authorized testing ASP by the Contracting Government to whose flag the ship is transferred. In such cases the ASP concerned should re-issue the Conformance test report on behalf of the Administration concerned henceforth indicating the new particulars of the ship but without changing the date of completion of the conformance test.In cases where the Conformance test report is deemed to be no longer valid, due to the transfer of the flag to another Contracting Government, a new conformance test should be conducted, prior to the issue of a certificate, by either a recognized ASP or an authorized testing ASP acting on behalf of the Administration concerned.
