Some of this aricle reads as if the author is a little naiive as to how container ports work, and just assumes that the cargo industry hasn't thought about these problems. There's plenty of room for innovation in cargo, but don't pretend that the people involved have never thought of the problem of losing containers at sea.

For example, I'm a little surprised by their recommendation that RFID chips be added to containers to prevent mis-loading, as if the current practice is to just randomly grab containers from stacks waiting by the shore.

There is already very sophisticated software (MACS3, or more specifically SEALASH that calculates the force added by an extra container on top of the stack) that does this stuff. There are also programs that read the numbers on containers as they go on and off the vessels, so that they are loaded onto the right trucks at the destination at the right time. If heavy containers end up on top, it's because they need to be removed first or were delivered last---that's a problem that can be solved, but it's a more complex problem than just adding an RFID tag to everything.
