ECONOMICS OF SELF-UNLOADERS

The high-capacity, gravity-type self-discharging vessel has become the dominant means for handling dry bulk cargoes on the Great Lakes of North America. In addition, these vessels are growing in importance in the St. Lawrence traffic as well as in some deep-sea trade routes. (Though these last still represent an extremely small component of the dry bulk fleet on the oceans of the world, they enjoy full employment when many dry cargo vessels are idle.) On these vessels, the additional cost of the unloading gear is reimbursed to the owners through the vessel's increased flexibility and reduced port time. The reduced port time results in a substantial number of additional cargoes being handled, while the increased flexibility of the self-unloading vessel allows the vessel owner to deliver cargoes where straight bulkers cannot.
