Underwater Diamond Wire Saw

摘要

In embodiments, an underwater wire saw comprises a frame, one or more arms connected to the frame with a predetermined number of the arms comprising a wire tensioner and a selectively telescoping or collapsing tube within a tube, and a continuous wire guided by a plurality of wire guides and tensioned using the wire tensioner. The underwater wire saw may further comprise a clamp.

1. A method of cutting a subsea structure, comprising:
a. positioning an underwater wire saw proximate a subsea structure, the underwater wire saw comprising:
i. a frame;ii. a first arm movably connected to the frame;iii. a plurality of wire guides, at least one of which being connected to the first arm;iv. a substantially continuous wire movably in communication with the wire guides;v. a continuous wire driver operatively in communication with the wire; andvi. a tensioner connected to the frame and operatively in communication with the wire, the tensioner dimensioned and adapted to guidingly receive and adjust tension on the wire; b. engaging the subsea structure with the cutting wire; c. using the adjusting tension in the cutting wire to a desired tension; d. advancing the cutting wire against the subsea structure; e. turning the cutting wire in a loop using the continuous wire mover; f. using the wire guides to guide the cutting wire from the wire driver and the tensioner in the loop; and g. advancing the first arm in a predetermined plane until a desired cut into the subsea structure has been achieved.
