Cutting Sheet Pile

Remotely deployed sheet cutting systems provide faster completions than do thermal based manual cutting methods. HyDrill sheet cutters increase productivity and improve quality without exposing personnel to adverse or dangerous working conditions below the surface.

Tool setup at any specified elevation is quickly accomplished and system feed-back permits positioning accuracies of +/- 0.005 of an inch to be repeated. Standard rigging allows depths of 50 feet to be achieved with all cutting operations monitored at the surface.

Several deployment methods, allowing independent sheet cutting operations are available. One example is the use of dual articulating jibs which lock onto the piles facilitating movement of the tool around the perimeter of the driven piles. Each jib can be used to locate tooling, position its counterpart, or provide power for the ascent and descent of the cutting tool. Operation from a small float-in platform is available and can be specified.

The tracking fixture allows the cutting tool to accurately traverse the contour of the sheet therefore; operation within close prox-imity of the pile is required. To avoid encumbering this assembly the deployment side of all sheet should be free of welded or bolted members and debris at the mud line should be removed prior to cutting operations. Corners, half sheets, or irregular sheet configurations may require track modifications and accurate field measurements to be supplied prior to mobilization.
