Unless the ship is exempted, a Ship's Waste Notification form must be completed and sent to the harbour authority at least 24 hours before arrival. (For details see Ship's waste notification below in this Section. )
Before arrival, either directly to the local authority or through an agent approved by the local authority, by radio, fax, email or other communications, so as to reach the local authority not more than twelve hours, and whenever practicable not less than four hours, before the expected arrival of the ship.
(1) Under Regulation 11: answer all questions as to health conditions on board put to him by a customs officer or authorised officer on arrival in port or if already in port; (2) under Regulation 13: report, before arrival, any infectious disease, etc. on board; and, (3) under Regulation 15: if there was anything to report under Reg. 13, complete a Maritime Declaration of Health.
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.
Broadly, ships flying flags of Party States, when on international voyages. Each chapter (I to XII) defines the ships to which that chapter applies. Application may depend on type of ship (e.g. chapter X - High Speed Craft), or date of build (e.g. chapter II-1 - Construction - subdivision and stability, machinery and electrical installations), area of operation (e.g. chapter V - Safety of navigation), tonnage (e.g. chapter IV - Radio communications) or cargoes (e.g. chapter VI - Carriage of cargoes and oil fuels). Each chapter may also exempt certain ships from the chapter's requirements.
