of exemptions therefrom, shall be carried out by officers of the

Administration. The Administration may, however, entrust the inspections

and surveys either to surveyors nominated for the purpose or to

organizations recognized by it.

    (b) The Administration shall institute arrangements for unscheduled

inspections to be carried out during the period of validity of the

certificate. Such inspections shall ensure that the ship and its equipment

remain in all respects satisfactory for the service for which the ship is

intended. These inspections may be carried out by the Administration's own

inspection services,  or by nominated surveyors, or by recognized

organizations, or by other Parties upon request of the Administration.

Where the Administration, under the provisions of Regulations 8 and 10 of

this Chapter, establishes mandatory annual serveys, the above unscheduled

nominated surveyor or recognized organization to:

        (i) require repairs to a ship, and

        (ii) carry out inspections and surveys if requested by the

appropriate authorities of a Port State.

    The Administration shall notify the Organization of the specific

responsibilities and conditions of the authority delegated to nominated

surveyors or recognized organizations.

    (d) When a nominated surveyor or recognized organization determines

that the condition of the ship or its equipment does not correspond

substantially with the particulars of the certificate or is such that the

ship is not fit to proceed to sea without danger to the ship, or persons

on board, such surveyor or organization shall immediately ensure that

corrective action is taken and shall in due course notify the

Administration. If such corrective action is not taken the relevant

certificate should be withdrawn and the Administration shall be notified

immediately;  and, if the ship is in the port of another Party, the

appropriate authorities of the Port State shall also be notified

immediately. When an officer of the Administration, a nominated surveyor

or recognized organization has notified the appropriate authorities of the

Port State,  the Government of the Port State concerned shall give such

officer, surveyor or organization any necessary assistance to carry out

their obligations under this Regulation. When applicable,  the Government

of the Port State concerned shall ensure that the ship shall not sail

until it can proceed to sea, or leave port for the purpose of proceeding

to the appropriate repair yard, without danger to the ship or persons on

board.
