Purpose
Instruction to Class (IC) 4-2019 lists the current computer software programs approved by the Norwegian Maritime Authority (the NMA) for calculating tonnage, intact or damage stability for ships registered in a Norwegian ship register.
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).
Definitions
None.
References
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.
Repeal
IC 3-2008 is repealed (a.k.a. NIS Circular 3/1998)
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.
When ROs are documenting the intact or damage stability, subject calculations shall be carried out in a computer software program approved by the NMA.
The list of computer software programs approved by the NMA is set out in the annex to IC 4-2019.
