The increasing demand for marine transportation of agricultural produce under controlled atmosphere (CA) conditions is leading owners of refrigerated ships to provide permanently installed on- board nitrogen generating plants and atmosphere control systems. The selection of the shipboard CA gas generating plant must take into account the vessel type, the cargoes to be carried, and the range of controlled atmosphere conditions to be achieved for different commodities. The shipboard CA gas generating plant can be situated on the ship's weather deck, installed in the vessel's main or auxiliary machinery spaces, located in a separate CA compartment, or a combination of these options. Ventilation of all spaces containing CA generating equipment and pipelines, combined with atmosphere monitoring and alarms, and safety training of all concerned personnel, provides an acceptable level of safety. Experience with installation and operation of shipboard CA systems demonstrates that, with careful attention to sealing of the cargo spaces, proper equipment selection and installation in accordance with classification society guidelines, a successful shipboard CA installation can be achieved.
