Special Containers & its Cargoes – OOG/Reefer

There are a variety of special cargoes that are loaded on every ship..

Most common of these special cargoes are :

  • Out of gauge Cargo (OOG)
  • Refrigerated Cargo (Reefer)

These special cargoes require special containers for the carriage of same..

Out of gauge Cargo (OOG) : Cargo that generally extends over and above the standard measurement of a General Purpose container..

OOG cargo is normally carried in Open Top containers (OT), Flat Racks (FR), Platforms (PL) due to the nature and size of the cargo..

Refrigerated Cargo (Reefer) : A refrigerated container or reefer is a shipping container used in intermodal freight transport that is refrigerated for the transportation of temperature sensitive cargo..

While a reefer will have an integral refrigeration unit, they rely on external power, from electrical power points at a land based site, a container ship or on quay..

When being transported over the road on a trailer they can be powered from diesel powered generators (“gensets”) which are attached to the container whilst on road journeys..

20′ Reefer Container – 20′ RF & 40′ Reefer Container – 40′ RF

Reefer containers are used to carry many cargoes that are sensitive to temperature changes and require a temperature controlled environment..

Examples include Frozen Meat, Fresh Produce, Fruits, Vegetables, some chemicals, Photo films etc..

Majority of the 40′ containers are high cube containers.. Many of the modern ships are designed to carry optimum 40’RF..

    Thank you for your asisstance. I have been looking for sites that can assist on loading of container whether OOG or normal GP..

  2. i’m ama,from university of colombo srilanka.thank u v.much 4 above link.i got most important things what i wanted.

  3. This is very nice for us in the shipping industry. Thanks for the website. You are now one of my favorites.

    • Hi Leazz, thats a difficult question to answer coz it depends totally on the vessel involved and the planning of the vessel.. The only time you will ever know FOR SURE is when the planning for the vessel is done..

  4. Hi, my management gave me a project on OOG and flat racks. I need to study them and give details such as loading/discharging procedures, from one end to another, stuffing and unstuffing and so on. Could you kindly assist me please? Thanks. Léazz

    • Hi Shafiek, flexitanks are used for the carriage of liquid cargoes.. Currently mainly wine is being carried in these flexitanks ex South Africa..

  5. The pictures for 20’/40′ PL (platform/tweendeck/bolsters) are in fact pics of collapsible Flatracks. Platforms do not have any
    end piece (collapsible or not). PL’s mainly used on RORO vessels to cater for non-wheeled cgo. True, you can in some instances use collapsed FR’s for the same purpose but generally load capacity is considerably different.

    For reefer containers suggest you go into more details of the different types of reefer containers on the market today. A long way fm the original SAECS clip-ons/simple reefer boxes. One example CA (controlled atmosphere) reefers. Interested readers can check apm-maersk.com/safmarine.com websites for more info or contact PPECB.
