Abstract
A cutter-coiler device that economically cuts and coils cylindrical piles, casings and conductor pipes to a depth below the surface of the sea floor. Although the device will cut and coil cylindrical piles, casings and conductor pipes above the sea floor, it is most effective for use where casings, conductors and piles must be cut, and pushed or coiled below the sea floor. Further, although the device is effective in cutting and coiling casings, conductors and piles that are cut below the sea floor, it is also effective on cutting and coiling cylindrical piles casings and conductor pipes that must be cut above the sea floor. The device includes a conventional pile driver or hammer, an anvil, a helmet, a spreader coiler, a coiler, cutter blades and a guide. The guide directs the cutter blades into the casing where the cutter blades cut the casing into sections and the spreader coiler pushes out on the sections causing the cut sections to flatten out and the coiler forces the section to roll up into a coil.
