Most of the things we wear, drive, fill on the tank or eat are brought to us over water. More than 90% of the world's trade is transported by ship, totalling 27 thousand billion tonne-miles in 2004 [5]. By 2007 IUMI (International Union of Marine Insurers) reports that 20% of the world's merchant fleet over 300 gross tonnes, or nearly 9000 vessels, were tankers [6]. 25 years ago the average tanker would have been manned by a crew of between 40 and 50. Today technological advances have contributed to decrease manning, in some cases to just above 20 seafarers on a Very Large Crude Carrier (VLCC).
