Naturally ventilated containers for the carriage of hygroscopic cargoes.

Naturally ventilated containers for international transport of hygroscopic commodities are now well established. Both theory and practice show that the greater the vent areas, the wider the range of conditions under which NVCs will succeed, but there are no established values for acceptable areas. Thetheory, conception and utilisation of NVCs are reviewed. Different vent configurations are tested for simulated and for real voyages.
