Tagging shipping containers
I like some of the ideas thrown around here. Attaching some sort of tracking beacon on the container provides several things: - If the container goes over, someone can know now, rather than days or weeks later that it's in the drink and not on the ship - Using economics, if the container is carrying merchandise of value that has the potential to survive immersion, I'm sure you could find salvagers who would be willing to go after it - If the container is carrying a cargo that is could have a significant negative impact to the environment, it could be found/retrieved/neutralized (assuming the shipping company doesn't try to hide the incident) - If the contents aren't worth salvage and isn't anything harmful, perhaps the beacon could provide some sort of short range data (AIS/VHF/other)to boats in the area to assist in avoidance - Worst case, floating containers could provide researchers data on ocean currentsOf course, there is the logistical hurdles of - Added cost : who pays for it? Shipper, shipping company, government? It all ends up getting paid for by the consumer in the end. - Administration : who runs/tracks it? Does each company track their own, create tracking companies solely for this purpose? There are already companies that track ships, why not track their cargo? - Technology : satellites, short/long range radio, GPS, AIS, etc. - Corruption/Crime : there may be some containers that don't WANT to be tracked and/or found if lost.Finally, maybe Tony B isn't that far off. Make the containers soluable, that way if they go swimming, they dissolve. If the contents are heavier than water, it goes to the bottom, if it's lighter than water it washes up on the beach, think about those stories of rubber ducks, athletic shoes and bags of Doritos! On the down side, soluable containers may have a tough time holding up on deck with rain and ocean spray. Maybe a pressure sensor that detects when a portion of the container is X feet below the surface, and then the tops/bottoms of the container disconnect, releasing their cargo - either to the public or Davy Jones, depending on density.T J
