Abstract
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.
Claims24
An underwater wire saw, comprising:
- a. a frame;
- b. a first arm movably connected to the frame;
- c. a plurality of wire guides, at least one of which is connected to the first arm;
- d. a substantially continuous wire movably in communication with the plurality of wire guides;
- e. a continuous wire driver operatively in communication with the wire;
- and
- f. a tensioner connected to the frame, the tensioner dimensioned and adapted to guidingly receive and adjust tension on the wire.

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;
- and
- vi. 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.
