Vessel traffic service.
A rule in major IMO conventions that, when inspecting a ship flying the flag of a State which is not a party to the Convention, Port State Control Officers must ensure that the treatment of such a ship and its crew is not more favourable than that of a ship flying the flag of a State party to that Convention. For example, many States have not yet ratified or acceded to MARPOL Annex VI, but ships flying their flags will still be required to meet the requirements of Annex VI to pass port State control inspections.
The Ship Security Officer (SSO) should advise the Port Facility Security Officer (PFSO) without delay. The PFSO should undertake an assessment of the situation in consultation with the SSO and agree on appropriate security measures with the ship, which may include completion and signing of a Declaration of Security. Any costs entailed in additional security measures would be settled by the ship.
