The 2010 Manila amendments was intended to include all agreed changes since 1995, address new technology, inconsistencies, interpretations and outdated provisions. There was also an overall commitment to harmonies the amended STCW Convention where practical, with the provisions of the 2006 ILO Maritime Labour Convention. The 2010 amendments continued to emphasize competence rather than sea service or period of training. The standard set by the convention applies to seafarers of all ranks serving on sea-going merchant ships registered under the flag of a country party to the convention.
