ARTICULATING
The patented design of our Articulating
Diamond Wire Saws increase the efficiency
and effectiveness of low-clearance cuts in the
subsea cutting world. The articulated design
only requires 2 feet of clearance around
casings and the cut is made at the bottom
of the saw, so there is no need to make
additional space and can minimize dredge
requirements.
• US Patents 8,651,098B2, 8,833,359,B2,
9,010,311B1
• Cuts flat with mudline at bottom of the
saw
• Reduces backside clearance footprint up
