xcalibre Abrasive Cutting Solutions – Jacket / Leg Cutting

Internal Leg Cutter (ILC)

The Internal Leg Cutter (ILC) is a robust, reliable and field proven tool that is used as part of Claxton's xcalibre Abrasive Cutting Solutions.

The ILC has a fixed upper body, a rotating lower nozzle assembly and six centralising pins at the upper body, strategically located for optimum tool alignment and stability before and after cutting. The centralising pins are operated by a cam, which in turn is powered by the electro-hydraulic control system to ensure tool alignment is synchronised.

• Covers 5-5/8" to 120" of pile/leg internal diameter as standard
• Can be adapted to other sizes as required
• Modular design
• Robust tool proven in the field

Internal Pile Cutter (IPC)

The Internal Pile Cutter (IPC) is a robust and reliable manipulator proven in the field and is part of Claxton's xcalibre Abrasive Cutting Solutions.

The IPC consists of a fixed cylindrical upper body, a rotating lower nozzle assembly and two sets of hydraulically driven centralising arms. The cutting head is extended by a pre-charged accumulator, allowing it to ride over seam-welds or non-conformities without damaging the manipulator assembly.

The IPC is deployed by vessel crane or independent winch system into the open top of the pile. The centralising arms and nozzle assembly are retracted, protecting them and allowing the IPC to slide down the internals of the pile. Once in position, the centralising arms and nozzle assembly are extended.

A complete cleaning/test pass is then carried out using HP water. This verifies that the manipulator is fully functional and that the nozzle is in contact with the pile wall rather than mud or scale deposits.

Once this pass is completed, abrasive is introduced to the HP water and a full cutting pass is completed, including a 10º overcut to ensure complete severance. The cutting head is rotated using hydraulics, with the process monitored by a radial encoder that provides accurate real-time readings of the nozzle position.

• Covers internal diameters from 5-5/8" to 120"
• Radial encoder gives real-time progress readout
• Robust, reliable manipulator

We have completed thousands of projects globally and have a track record of cutting:

• Single & multi string casing / wellheads / conductors - see more on this
• Which can be a mixture of Uncemented or Cemented & eccentric
• We have been involved with large scale projects for the cutting and recovery of platform jacket legs & piles
• And can comfortably handle small and large diameter cutting - completed internally or externally

As xcalibre is our proprietary technology it enables Claxton to deliver unmatched performance and reliability - limiting potential NPT and maximising offshore execution efficiency.

We provide fit for purpose solutions – cutting through decommissioning complexity to deliver results for our clients.
