Abstract: The present invention is directed to a method of salvaging an elongated oil well tubular that extends downwardly from an oil well platform as well as a saw apparatus of improved configuration. The method includes supporting the tubular in a generally upright or vertical position. A cutting apparatus is placed next to the tubular. The cutting apparatus includes a frame that supports a lifting device and a rotary cutter. The lifting device moves the rotary cutter from a first position to a second position that is higher than the first position. The second position is closer to the tubular than the first position. The rotary cutter can travel in an arcuate path when moving from the first position to the second position. The cutter moves along a selected path to cut the tubular. After cutting, the cut section is removed and the tubular then elevated so that an additional cut can be made. This procedure is repeated multiple times until the tubular has been salvaged, cut into many smaller pieces or sections.

Abstract: A method and apparatus for angularly drilling during a tapping procedure into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle.
