ESCRIPTION
The subsea wire saw is designed to cut submerged pipe of
varying materials and thicknesses. The machine operates on
hydraulic power, and is controlled remotely using the
Wachs topside control panel (TCP).
The saw uses a continuous-loop diamond cutting wire and a
hydraulic feed system that advances the cutting wire
through the pipe. Using a wire rather than a blade provides
more reliable cutting on varied pipe materials, and helps
avoid binding of the cutting mechanism if the pipe bends
and pinches while the saw is engaged.
The subsea wire saw has three hydraulic drive circuits:
•
Cutting drive: operates the drive wheel that drives the
cutting wire.
•
Feed drive: operates the bow holding the wire drive sys-
tem, to feed the wire through the pipe and retract the
bow when finished cutting.
•
Clamp drive: operates the clamping arms that secure the
machine to the pipe during cutting.
