ABSTRACT:
A method and apparatus for cutting wharf or bridge pilings underwater which tilizes a neutrally buoyant air tube to conduct a laser beam from a laser source on a barge or other surface vessel to an air filled collar which is clamped to the piling to be cut. The laser beam is guided via the air tube to the piling where laser energy and combustion are utilized to cut the pile, and compressed air or other gases purge the collar of smoke and water during the cutting.
