I understand the reason why ATBs exists, but not why they are allowed to operate in open waters outside the GoM.
OK, I know, I know. Greedy pigs pay off equally greedy politicians and the watch dogs are more occupied with planning for their pension age than worrying about the safety of seafarers.
There are obvious additional risk factors when towing or pushing, thus insurance premium is higher than for similar transport by ship. I presume that as long as they can charge premiums corresponding to the risk + a large profit margin, the Underwriters are happy and the consumers pick up the tab in the end anyhow.
As long as nobody protest, why rock the boat??
But how much longer will this be tolerated by Canada, especially when carrying Petroleum products or Chemicals along the pristine BC coast???
