More recently, the single-quadrant shiploader we installed at the Collahuasi copper terminal in Iquique, Chile featured an enclosed tubular boom for dust and spillage containment. Shiploaders vary widely in size, loading rate and cost. The optimal loading rate for a terminal is governed by factors such as ship size, annual throughput, environmental standards and the commodities being moved. While the traveling shiploader is probably the most common worldwide because of its relatively modest cost and full vessel coverage, the marine structure and access conveyor costs associated with this shiploader can be high. The Sandwell-designed dual quadrant shiploader has proved to be very successful for large vessels in particular, providing more even loading, reduced hatch change time and the increased security of a dual system, often at a lower overall cost of shiploaders and marine structures.
Dust control is also relatively easier with a dual quadrant system.
In the context of a master plan for a port or marine terminal, shiploaders are generally only a small part of the total cost. But a handling system can make or break a terminal, and the shiploader is a vital component of that mechanical main artery that moves products onto vessels.
