Sometimes sailors blame damage incurred at sea on a half-submerged shipping container. I've seen estimates of the number of shipping containers as high as 10,000 per year. Reasonable? Some people have tried counting.

Between 2008 and 2013, and excluding these two maritime disasters, an average of 546 containers were lost at sea. When Comfort and Rena are added to the equation, that number climbs to 1,679 containers per year. The MOL Comfort, which broke in half on June 17, 2013 and subsequently sunk during a prolonged attempt to recover her stern, was the worst container ship disaster in history: 4,293 containers were lost in a single incident. The MV Rena grounded on a reef of the New Zealand coast in late 2011, spilling 900 containers over the side.
Even with these two maritime tragedies, the number of containers lost at sea each year come nowhere close to 10,000. When you consider that roughly 120 million containers were moved across the ocean in 2013, 1,679 lost containers per year seems positively minuscule.
