Abstract

A method of laying a pipe under water includes the step of introducing matter to the interior of the pipe to permit the pipe to sink in the body of water. The matter comprising one of the group consisting of: solid matter; a liquid; a liquid and solid matter. The overall density of the pipe including the matter introduced to the interior of the pipe is greater than the density of the body of water in which the pipe is to be laid. The solid matter could be a cable. The liquid could be a salt solution which may comprise NaCl (sodium chloride) or ZnCl2 (zinc chloride), or any other suitable salt. Also claimed is a plastic pipe for laying at the bottom of a body of water wherein the interior of the pipe contains matter wherein the pipe is coiled onto a drum.
