(quoted from post at 23:58:25 01/12/20) 15 years ago, he company I worked for had a bunch of custom machinery being built in Europe. We met & talked with the logistics company that organized the trip from door to door. Some interesting facts surfaced during that meeting:
1) An average of 10,000 containers per year are lost (overboard, ship to the wrong port & no paperwork, unclaimed, stolen, etc)
2) Containers DO fall off ships in storms for various reasons.
3) Containers are rain tight when new, but not necessarily water proof. Falling into the water, they will all eventually sink. The time to sink depends on the integretity of the container, and weight of the cargo. Yes, for a while, they are hazards to other ships.
4) The captain of the ship has the right to start throwing containers off his ship if the ship is in jeapordy. Rule of the sea is that if YOUR containers were thrown overboard, resulting in saving mine, MY insurance company is responsible for paying for your losses.
Other note:
5 years or so ago, the man (Maersk) who invented the concept of containerized shipping as we know it, died. Some time after his death, word went out, and at a particular time around the world, all container ships blew their horn for a minute to commemorate his passing.
