2.5.1 If the ship does not carry valid certificates,
or if the PSCO, from general impressions or observations on board,
has clear grounds for believing that the condition of the ship or
its equipment does not correspond substantially with the particulars
of the certificates or that the master or crew is not familiar with
essential shipboard procedures, a more detailed inspection as described
in this chapter should be carried out, utilizing relevant appendices.
2.5.2 It is not envisaged that all of the equipment
and procedures outlined in this chapter would be checked during a
single port State control inspection, unless the condition of the
ship or the familiarity of the master or crew with essential shipboard
procedures necessitates such a detailed inspection. In addition, these
Procedures are not intended to impose the seafarer certification programme
of the port State on a ship entitled to fly the flag of another Party
to STCW or to impose control procedures on foreign ships in excess
of those imposed on ships of the port State.
