|Table 9 shows the overall trends in refrigerated container slots on ships. These also include slots for porthole containers, although they have tended to be on the decrease since the last porthole ships were built in 1995. Since generally one slot is provided for a 40' container on ships other than porthole ships, the actual number of slots is approximately half that shown (1 FEU = 2 TEUs).

The number of refrigerated container slots on ships (see Table 9) is gowing at approximately 14% per year, around the same rate at which the number of containers is increasing.
Table 10 shows the development in the size and age of the container ship fleet including the refrigerated container capacity at the end of 1997. A total of some 2,200 were available for transporting refrigerated containers. The large ships with a high refrigerated container capacity which were over five years old in 1997, were ships used to transport porthole containers. Recently built ships are exclusively ships used to transport integral containers. The ships of the "Regina Maersk" group, for instance, have 700 refrigerated container slots, which is equivalent to 1,400 TEUs. The largest refrigerated container ship in the world in 2004, the "Monte Cervantes", owned by Hamburg-Süd, has more than 1,365 slots for 2,450 TEU refrigerated containers. This gives refrigerated containers a share of almost 50% of the overall capacity of the ship of 5,100 TEU.
