3.5.1 Notwithstanding the fact that it is impracticable to define a ship as substandard solely
by reference to a list of qualifying defects, guidance for the detention of ships is given in
appendix 2.
3.5.2 In the case of a detention, the PSCO will immediately notify the flag Administration in
writing and include the report of inspection. Likewise, the RO which has issued the relevant
certificates on behalf of the flag State shall be notified, where appropriate. The parties above
will also be notified in writing of the release of detention.
