When the MSC Napoli ran aground off the UK's south coast in January 2007, 137 out of the 600 containers it was carrying on deck were at least 10 percent heavier or lighter than was declared on the ship's manifest. In another high-profile accident, the capsizing of the Xpress Container Line vessel Deneb during unloading at Algeciras in June 2011, an even higher percentage of boxes - 64 out of 150 - were not laden as recorded.
