The loss of three modern ships, with heavy loss of life in 2010, was a brutal reminder of this. All were carrying Indonesian nickel ore; cargo, which by its very nature and the fact that it is mined in an area of excessively high rainfall, is recognised as hazardous and highly prone to hygroscopic effects.It would be easy to suggest that it was inadequate testing to determine the water content that was the problem, or that prudent operators should reject such charters out of hand. But the fact is that these cargoes are of increasing value, so that the demand for them by steelmakers is high and growing.It is also a fact that there is a distinct lack of expert advice available in many of these areas, and a notable shortage of science in the determination of water content.
