According to a World Shipping Council report, up to 1,382 shipping containers are lost at sea each year

The figure is based on three year averages calculated over a 12-year period – which represents 80% of the global vessel container capacity. This was up until 2019.
Other estimates paint a more concerning picture: between Nov 2020 and Jan 2021 alone, 2,675 sea containers were lost at sea. Furthermore, 2021 witnessed the largest rise in lost shipping containers since 2013.
Reasons for containers getting lost at sea
One marine biologist has estimated that there are approximately 12,000 shipping containers lost in the world’s oceans.
The human factor has been identified as a key cause of lost sea containers, which includes taking shortcuts to save costs and not declaring container weight properly. In addition, poor packing inside containers and lack of stowage planning has contributed to this as well.
However, the human factor alone is not blameworthy – climate change has contributed greatly to lost containers just as much, if not more. Changing weather patterns in the Pacific Ocean, which is home to some of harshest weather conditions in the world, and the rise in China-US container traffic combined with the strongest Northern Pacific winds since 1948 – are all prominent climate-related factors responsible for containers getting dislodged from shipping vessels and lost at sea.
The above factors in particular make containers highly susceptible to damage from storms.
With all of the above in mind, many shippers have identified the main cause to be ship groundings and structural failures when stacked together.
It is believed that more than 50% of lost containers are because of either ship groundings or structural failures. Every time a container is lost, it can prove to have devastating consequences for marine life – lost sea containers can potentially destroy aquatic habits and even help the spread of invasive species. Lost containers can also release dangerous materials or cargo into the ocean. In a recent incident, a ship carrying sulphuric acid broke down, and released 6,000 pounds of sulphuric acid.
