This Manual provides practical information to Governments and
competent (port) authorities, in particular those in developing
countries, as well as the shipping industry, agencies and waste
contractors seeking guidance when implementing MARPOL.
It also provides guidance on how to deal with possible
inadequacies, as, in order to comply fully with MARPOL, a party
State has to ensure the provision of adequate port reception
facilities meeting the needs of ships using their ports, without
causing undue delay to the ships.
