Does it mean that they can store loaded reefer containers only on the deck?
A. No, not necessarily. Reefer containers can also be stored inside the cargo holds. But the heat given out by the condensers of all the running reefer containers inside the cargo hold should be led outside efficiently. Otherwise, there will be heat accumulation inside the cargo hold and the refrigeration machinery will not function efficiently. That means the ship’s cargo hold ventilation system should be so designed to allow the required number of air changes so as to maintain the temperature inside the cargo hold within the permissible limits. Alternatively, they may use water-cooled condensers. In such a case, the cargo hold should be equipped with water circulating system with pipelines running along the sides of the cargo hold which can be connected to the individual reefer containers through a pair of flexible pipes one for the inlet and the other for the outlet. Often, such containers are marked “IN HATCH STOWAGE ALLOWED”. By looking at a reefer container, by noticing the water
