Canada A machine that looks like it is making the pipe right there on the spot. MCUS/L - Machines that look like mini cranes carrying the yards and yards of pipe. MCUS - Empty oil drums tied on to the pipe. MCUS - A engineer giving direction. MCUS - The work crew waving to the camera and on the ground sits the pipe with empty oil cans tied on the top so when there transported over water they will not sink.
