How will the new MLC (Maritime Labour convention) be kept more up to date than the existing conventions?

The part of the Convention which is expected to need updating from time to time, namely the two-part Code relating to the technical and detailed implementation of the basic obligations under the Convention, can be amended under an accelerated procedure (“tacit acceptance”) (provided for in Article XV) enabling changes to come into effect, for all or almost all ratifying countries, within three to four years from when they are proposed.
