UPDATE ON SELF-UNLOADING DRY-BULK VESSELS, 1969-1976

The Author deals with the high-capacity gravity type self-discharging vessel that has become the dominant means for handling dry-bulk cargoes on the Great Lakes of North America. Other forms of self-unloading vessels and specialised carriers for products such as bulk cement, but which are only capable of low discharge rates, are not discussed. The self-unloader has become the common means of transporting bulk on the Great Lakes and this type of vessel is growing in importance in the St Lawrence traffic, as well as on some deep-sea trade-routes. It is considered that automated unloading procedures are essential for the future dry-bulk cargo trades and, to this end, the self unloading vessel has proved a viable solution to the north American transport problem. The additional cost of this type of vessel must be compared with the savings in capital and operating costs gained at the various discharge terminals. Order from BSRA as No. 47,580.
