Abstract: A placement and support system for installing long lengths of connected pipe sections and method of using the same are provided having a series of pairs of spaced apart piles that are installed at predetermined sites by pile-driving into the floor of an expanse and, in particular, a body of water. Each pile has a bent seat at lower end and the piles are driven until the seats are positioned at the desired distance above the floor. The sections of pipe are preconnected on land or on a barge to a desired length. A prefabricated pipe saddle assembly is installed between each pair of piles and positioned above the water line by wedging or a hydraulic jack to form a series of pipe saddle assemblies. Each pipe saddle assembly has a transverse support beam. There is a pipe sleeve at each end of the support beam dimensioned to slide over the piles. A generally U-shaped pipe saddle is affixed to the transverse beam.
