1.7.1 Every diving system, issued with a Certificate
under section 1.6, is subject, whilst under the control of an Administration
other than that which has issued the Certificate, to control by officers
duly authorized by that Administration for verification that the Certificate
is valid. Such Certificate should be accepted unless there are clear
grounds for believing that the condition of the diving system or its
equipment does not correspond substantially with the particulars of
that Certificate. In that case, the officer carrying out the control
may take such steps as will allow the system to operate on a temporary
basis without undue risk to the divers and the personnel on board.
In the event of this control giving rise to intervention of any kind,
the officer carrying out the control should inform the Administration
or the Consul or, in his absence, the nearest diplomatic representative
of the State in which the ship or floating structure is registered
in writing forthwith of all circumstances on the basis of which intervention
was deemed to be necessary.
1.7.2 Notwithstanding 1.7.1, the provisions of
1.6 are without prejudice to any rights of the coastal State under
international law to impose its own requirements relating to the regulation,
surveying and inspection of diving systems engaged, or intending to
engage in diving operations on those parts of the sea-bed and subsoil
over which that State is entitled to exercise sovereign rights.
