4.5.1 NGHPs may be carried in cargo holds of "integral
tank" type as defined in paragraph 4.2.1 of
the IGC Code provided that the structures of cargo holds are evaluated
through analyses taking into account thermal stresses neglecting insulation
inside the cargo holds.
4.5.2 A secondary barrier is not required for
cargo containment systems for NGHPs.
Note The requirements for cargo containment systems of types
other than "integral type" may be considered later, as necessary.
