I do know a guy that worked Caribou for many years..He's confident there's no real concern for asbestos or PCB's.,the worst is whats in the bilge's. A vac truck hazmat suit with supplied air would do it for that.
The Freighter did have some on board before she left,unless a major clean up was done before hand.Not likly as asbestos is quite well understood to be of no threat unless disturbed or exposed,even less harmfull if its wet.
Last time the Frighter had an issue with asbestos ,a team was sent in ,cleaned up the exposed junk,encased what could be left alone ,and all areas that were containing asbestos were clearly labeled in accordance with regulations.
As far as the Caribou is concerned.I'll stick by my theory that a firm does want her but has hired a firm(possiably Egyptian) to make the international transfer.
My reason is simple ,I worked for a guy that bought and sold heavy equipment globally. He is a very intelligent man ,intelligent enough to use and pay people to handle international transfers to move his equipment.I distinctly remember he bought a piece of equipment that was for sale in Canada,but bought it through a European firm instead of just going out and getting it. It was just more benifical to do the transaction that way..
Anyone of us here can go abroad and buy a ship,equipment,no problem..But to get it out of one boarder through the system and into another boarder with proper documentation will require people who know the system's.
