The old merchant ships in the Reserve Fleets are way beyond usefulness. Scrapping them would have not been much of a problem until Al Gore got in the way. Al Gore lead the charge to prevent the Maritime Administration from scrapping ships overseas that had asbestos in them. So the ships just sat and rusted for years. The total fuel remaining aboard the ships for many years equaled millions of gallons, a disaster waiting to happen. In the last few years, the Maritime Administration (MARAD) has made significant progress in removing the oil from the ships. Asbestos has been removed from ships prior to being scrapped overseas.
But this idea also is being thwarted by the Enviro’s even though it is has been proven that creating artificial reefs that are great for fishing or diving.
So, put the fuel recovery job up for a bid; an oil company with a nearby refinery can pump it out and reprocess it; everybody wins!
