How many containers are lost at sea?
This is a question that is often asked.
A figure often quoted is "about 10'000 containers lost per year".
The World Shipping Council whose members make up 90% of the world's container ship capacity polled its members in 2014 to get an accurate answer.
A lot but still a lot less than the 10'000 figure.
Whatever the number, they represent a danger to world shipping.
