Whose container was found at sea?

Give things back to their original owners. A container floating on the high seas does not mean that it belongs to whoever finds it. According to the maritime convention, containers floating on the high seas should be returned to their original owners after being found, in order to safeguard the interests of maritime navigation. If the container is hung into the sea by strong wind, it is a force majeure factor, which shall be borne by the owner alone. This is called "particular average".
