1.5.1 Article I(3) of SOLAS PROT 1988, article I(3) of LL PROT 1988, article 5(4) of
MARPOL, article X(5) of STCW 1978, article 3(3) of AFS 2001 and article 3(3) of BWM 2004
provide that no more favourable treatment is to be given to the ships of countries which are
not Party to the relevant convention. All Parties should, as a matter of principle, apply these
Procedures to ships of non-Parties in order to ensure that equivalent surveys and inspections
are conducted and an equivalent level of safety and protection of the marine environment is
ensured.
1.5.2 As ships of non-Parties are not provided with SOLAS, Load Lines, MARPOL, AFS or
BWM certificates, as applicable, or the crew members may not hold STCW certificates, the
port State control officer (PSCO), taking into account the principles established in these
Procedures, should be satisfied that the ship and crew do not present a danger to those on
board or an unreasonable threat of harm to the marine environment. If the ship or crew has
some form of certification other than that required by a convention, the PSCO may take the
form and content of this documentation into account in the evaluation of that ship.
The conditions of and on such a ship and its equipment and the certification of the crew and
the flag State’s minimum manning standard should be compatible with the aims of the
provisions of the conventions; otherwise, the ship should be subject to such restrictions as are
necessary to obtain a comparable level of safety and protection of the marine environment.
