(9)Relevant International Conventions leave important points of interpretation of the requirements to the discretion of the Parties. On the basis of their own interpretation, Member States issue to all ships flying their flags, that are subject to the provisions of relevant International Conventions, certificates certifying their compliance with these provisions. Member States enforce national technical regulations, some provisions of which contain requirements other than those in the Conventions and in associated technical standards. An appropriate procedure should therefore be established in order to reconcile divergences in the interpretation of existing requirements which may occur upon a request for transfer of register.
