Sub-Classification of Bulk Carriers
Bulk carriers are a class of ships but even they can be further subdivided into various types.
Geared Carriers - the ship shown in the figure below is known as a geared carrier which means that it has got its own gear (or equipment) to load or unload cargo. This gear is in the form of cranes or derricks. In the given picture you can clearly see four cranes in yellow colour between the cargo hatches.
Gearless Carriers - Some ships do away with the cranes and derricks but depend on the equipment available at shore to load/discharge cargo and these are known as gearless carriers. Obviously the utility of such a ship is greatly dependent on the equipment available at shore, so they may not be able to go at all the ports which do not have such facilities and depend on the ships equipment for loading/unloading of cargo.
Bulk carriers can also be divided on the basis of their cargo carrying capacity.
Mini bulk carriers or MBCs are relatively small bulk carriers usually have capacity between 500 – 2500 tons and are used typically used for coastal trading.
The other types of bulk carriers in the increasing order of the cargo carrying capacity are
- handysize carriers
- handymax carriers
- panamax carriers
- capesize carriers
- very large bulk carriers.
We will learn more about bulk carriers and their various aspects in later articles but as of now we will proceed to talk about tankers in our next article
