Part 21 is divided into two sections.
Section 1 incorporates the SOLAS 74 Chapter IX requirement that shipowners implement a shore-based and shipboard safe management system in compliance with the International Safety Management Code (ISM Code).
Section 2 requires ships be in an approved Safe Ship Management (SSM) system managed by and approved by the Director of Maritime NZ for that purpose.
The rules prescribe the conditions of entry to a Safe Ship Management system and for remaining within that system. It includes the requirement for compliance with the NZ Safe Ship Management Code, which appears as an appendix to Part 21.
