Industry surveys, such as those published by the World Shipping Council, have reported long-term averages in the low thousands per year, with recent years lower. Compared with the hundreds of millions of container movements each year, that&rsquo;s a tiny percentage &ndash; but every lost box is a problem.<\/p>\n<figure class=\"chb-figure\"><img src=\"https:\/\/cargoholidays.com\/wp-content\/uploads\/2021\/09\/AdobeStock_344566703-1024x483.jpeg\" alt=\"Containers lost at sea &ndash; stacked containers being loaded on a ship\" title=\"Containers lost at sea &ndash; stacked containers being loaded on a ship\" width=\"1024\" height=\"483\" loading=\"lazy\" decoding=\"async\"><figcaption>Containers are locked and lashed in stacks before every voyage.<\/figcaption><\/figure>\n<h2 id=\"why-containers-fall-overboard\">Why containers fall overboard<\/h2>\n<ul>\n<li><strong>Severe weather:<\/strong> huge waves and violent rolling put enormous loads on stacks &ndash; see <a href=\"https:\/\/cargoholidays.com\/es\/cargo-ship-in-a-storm\/\">cargo ships in storms<\/a>.<\/li>\n<li><strong>Parametric rolling:<\/strong> a dangerous resonance in certain head or following seas that makes ships roll heavily.<\/li>\n<li><strong>Wrong weights:<\/strong> mis-declared container weights upset stack calculations.<\/li>\n<li><strong>Lashing failures:<\/strong> worn or wrongly fitted twist-locks and lashing rods.<\/li>\n<li><strong>Stack collapse:<\/strong> one failure can bring down a whole row.<\/li>\n<\/ul>\n<h2 id=\"famous-container-spills\">Famous container spills<\/h2>\n<p>In 1992 a container of bath toys was lost in the North Pacific, and thousands of plastic ducks and frogs drifted for years, helping oceanographers study currents.
