Among the possible reasons for this phenomenon we find
The rush, or pressure for temporality such as supplying goods by December, mitigating delays and delays generated by the pandemic and global containment.
Alterations by meteorological phenomena, such as strong winds.
The record for lost containers was presented in 2013, when the ship MOL Comfort was literally split in two, resulting in 4,293 containers at the bottom of the sea.
The International Maritime Organization IMO, which is part of the UN and regulates maritime transport, doesn't point out very specific causes. However, experts in this field indicate that most of the containers lost recently ended up in the Pacific Ocean last winter.
If you compare the number of containers lost with the number transported is low because more than 226 million containers are transported per year, so losing just over 1,000 does not seem significant, but the operational impact of various companies and the economic if it generates levels of concern, adding from the debates that arose as a result of the blockade on the Suez Canal.
As some experts indicate, there are systems that allow to secure the containers on the ship through security locks that hook each other and make it more difficult that they can be lost at sea. However, transport undertakings may take out insurance for such events.
Once lost, containers are not intended to be rescued from the sea, generating negative and positive impacts on the marine ecosystem.
