There are two amendment procedures, Article XIV for the whole MLC, and Article XV  to amend the Code.  The Article XIV express ratification procedure mirrors present procedures to revise Conventions. The section to be updated on a timely basis the Code on the technical and detailed implementation of the basic obligations can be amended through an accelerated procedure (tacit acceptance) within Article XV. This uses a well-established IMO procedure and enables changes to come into effect for all or almost all ratifying countries three to four years post proposal. It will provide a  more current Convention than existing ones. A ratifying Member is not bound by a Code amendment entering into effect under Article XV, if it expresses formal disagreement within two years.
