Elements and Performance Criteria

General context
Work must be carried out in compliance with mandatory rules and regulations and IMO Conventions and Codes including the relevant sections of the AMSA Marine Orders and ensuring that applicable codes, guidelines and standards recommended by IMO, the classification societies and maritime industry organisations are taken into account.
