Upon review of the results of the nine year period (2008-2016) surveyed, the WSC estimates that there were on average 568 containers lost at sea each year, not counting catastrophic events, and on average a total of 1,582 containers lost at sea each year including catastrophic events.

Impact of ship breaking on biodiversity Shipbreaking activities contaminate the coastal soil and sea water environment mainly through the discharge of ammonia, burned oil spillage, floatable grease balls, metal rust (iron) and various other disposable refuse materials together with high turbidity of sea water.

For loose sand it is 29, 32 for dry, 33 for rammed, 38 for wet and 41 for wet packed. The most likely likely answers are then 32 for dry and 40 for wet, once you allow for wastage.

Shipping containers usually come in two sizes, either 20 feet by 8 feet or 40 feet by 8 feet. The smaller of the two equals about 160 square feet of living space, while the larger container gets you 320 square feet.

A 20-foot-long (6.1 m) ISO container equals 1 TEU. Two forty-foot containers stacked on top of two twenty-foot containers. These four containers represent 6 TEU.

A 20 ft open top container has a maximum load of approximately 28 metric tons, while the 40 ft open top container can hold up to 30 metric tons.

The numbers are staggering: There are 5.25 trillion pieces of plastic debris in the ocean. Of that mass, 269,000 tons float on the surface, while some four billion plastic microfibers per square kilometer litter the deep sea. Scientists call these statistics the "wow factor" of ocean trash.

We are producing over 300 million tons of plastic every year, 50% of which is for single-use purposes – utilized for just a few moments, but on the planet for at least several hundred years. More than 8 million tons of plastic is dumped into our oceans every year.

According to a study from Plymouth University, plastic pollution affects at least 700 marine species, while some estimates suggest that at least 100 million marine mammals are killed each year from plastic pollution.

There are estimated to be over 128 million pieces of debris smaller than 1 cm (0.39 in) as of January 2019. There are approximately 900,000 pieces from one to ten cm. The current count of large debris (defined as 10 cm across or larger) is 34,000.

Indeed, a plastic ocean of those substances might be in our future. To get from new polyethylene terephthalate plastic bottles in ocean waters to those little microplastics can take anywhere between 450 and 1,000 years.

Here's a ballpark estimate for the price of one-trip containers: 20 Foot Shipping Container: retails at US$3,000. 40 Foot Standard Shipping Container: retails at US $4500. 40 Foot Standard High Cube Container: retails at US $5000.

Accidents involving American and Soviet ships, bombers and rockets have left at least 50 warheads and nine nuclear reactors scattered on the ocean floors since 1956, according to a comprehensive study of naval accidents that was released today.

I'd say majority of Cruise Ships today have 12 to 16 decks (plus deck 0 or twin deck or depends from ship how they call it).

According to the World Ocean Wikipedia article, there are 1,332,000,000 cubic kilometers of water in the ocean, which is 1,332,000,000,000,000,000,000 liters.

But it takes the ocean 450 years to break down the plastic. This is the estimate from the US' National Oceanic and Atmospheric Administration (NOAA) and Woods Hole Sea Grant, which compiled data showing the length of time for man-made marine debris to biodegrade in the sea.

They found that China and Indonesia are the top sources of plastic bottles, bags and other rubbish clogging up global sea lanes. Together, both nations account for more than a third of plastic detritus in global waters, according to a report in The Wall Street Journal.
