Application

IC 4-2019 applies when Recognised Organisations (ROs) are authorized to approve tonnage measurements, intact and damage stability documentation for ships delegated pursuant to annexes I, II or III to the Agreement of 1 June between the Ministry of Trade, Industry and Fisheries and ROs (the Agreement).

The Agreement articles 2.2 and 2.3.

Background

Tonnage, intact or damage stability calculations are routinely carried out applying dedicated and specialist computer software programs.

Item

When ROs are calculating the gross and net tonnages as required by international instruments, subject calculations shall be carried out in a computer software program approved by the NMA.
