Internal Pile Cutting and Jacket Removal

Internal Cutting Tool Description and Methodology

In order to complete the internal cutting scope, Proserv proposes to utilise our internal pile cutter (IPC) in conjunction with the Jetcut system. The IPC is a robust, reliable and field proven manipulator consisting of a fixed cylindrical upper body, a rotating lower nozzle assembly and two sets of hydraulically driven centralising arms. During deployment, the centralising arms and nozzle assembly are retracted into the body of the tool protecting them and allowing the IPC to slide down the internals of the pile unhindered if angled. A circumferential encoder gives real time readout in degrees of progress through the cutting operation.

As the centralising arms do not clamp the IPC in place, only hold in centrally, the manipulator can be easily recovered by deployment crane in the event of hydraulic failure. The cutting head is extended by a pre-charged accumulator, allowing it to ride over seam-welds or non-conformities without any risk of damage to the manipulator assembly. The IPC is deployed by vessel crane or independent winch system into the open top of the pile. Once lowered to agreed cut elevation, the integral centralising arms are extended to adjust the manipulators position within the pile. Next, the nozzle assembly is extended out by a preset accumulator until the guide wheel contacts with the inner wall off the pile. A complete pass is then carried out using only HP water to verify that the manipulator is fully functional and that the nozzle is contact the pile wall rather than mud or scale deposits. Once this cleaning / test pass is completed, abrasive is introduced to the HP water stream and a full cutting pass completed, including a 10 degree over cut ensuring complete severance.

The circumferential movement of the cutting head is controlled using hydraulics, with the cutting process monitored by a radial encoder which gives the operator accurate real time readings of the nozzle position within the pile. With the information supplied please be advised the work scope may be subject to change upon further details being received. Subject to the contract Proserv will provide a project specific operation manual that will include; full work scope, procedure, safety risk assessment and all relevant documentation.
