Underwater Diamond Wire Saw

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.
