Despite the reduction in its use in western countries, coal is still a major fuel worldwide, accounting, together with iron ore, for the majority of ocean-going bulk freight. This global trade poses a major challenge to shippers in handling the various sizes, types and blends of coal, and also in coping with the abrasive characteristics of the fossil fuel. The problem is that coal is high in silica, a mineral that causes erosion and wear, in the plant and equipment used to process it. In the pressurised world of bulk carriers, where coal is handled in quantities of millions- of- tonnes per year, the ramifications of this problem can be very serious, resulting in extended ship layovers if not addressed. Consequently, it makes economic sense to take appropriate measures to protect against the sliding friction and impacts that cause wear.
