The IMO Convention
(1969) meant a transition from the
traditionally used terms gross register tons (grt)
and net register tons (nrt) to gross tons (GT) and
net tons (NT).
Gross tonnage forms the basis for manning
regulations, safety rules and registration fees.
Both gross and net tonnages are used to calculate
port dues.
The gross tonnage is a function of the moulded
volume of all enclosed spaces of the ship. The net
tonnage is produced by a formula which is a function
of the moulded volume of all cargo spaces of the
ship. The net tonnage shall not be taken as less
than 30 per cent of the gross tonnage.
