Abstract
A method and apparatus for laying continuous pipe particularly for offshore oil installations and wherein said continuous pipe is pre-formed into flat spirals of pre-selected inner and outer diameters depending upon available handling equipment and arranged in stacks in which each flat spiral is interconnected with the adjacent flat spiral. A stack of flat pipe spirals is positioned on a power driven rotatable pipe spiral carrier mounted on a deck of a pipe laying vessel. Pipe is withdrawn from the stack of spirals by rotating the pipe carrier and moving the pipe through pipe straightening and tensioning means, after which the pipe is fed to suitable pipe laying means for connecting the pipe to subsea installations.
