Thank you for this post. An illustration of your #s 7, 8 and 9 is the machinery that they have developed (and patented) for quickly and easily laying down the lining "carpet" rolls and for extracting the oil from water for on site water disposal from the sludge. Two slides in the presentation show this machinery. Surprising to me is how mobile it is for them to locate at the construction site or the on land pipeline locations. When I saw the patents I wondered how they would exploit them. They had the machines made for themselves and rent them out for specific jobs. Certainly a large plus for the engineering firms deciding who to do business with.
