ABSTRACT:
A method of laying an underwater pipeline underneath an ice sheet by a bottom pull which includes making up a pipe string, on a first shore of a water crossing, providing a first cable connection along the upper surface of the ice sheet between a pulling location and an on-ice pull sled, attaching a second cable between the pull sled and the leading end of the pipe string, cutting a slot through the ice along the path which the pipe is to take, ahead of the pull sled, and pulling the pull sled over the upper ice surface so as to tow the pipe string along the water bottom by means of the second cable which is submerged through the slot.
