The decommissioning of subsea oil and gas installations presents many difficult challenges, each needing to be overcome safely, within budget and without causing harm to the environment.
One example of these problems is the removal of piles or ‘strings’, which may have been used for structural purposes, or as the drill string within a wellhead for transporting the oil from beneath the sea bed.
A product which makes this achievable is a ‘single string cutter’. This particular product is designed for cutting through cylindrical walls made from a ‘single’ material.
This tool is capable of severing a single string of casing, conductor or pile using efficient cutting technology, so let’s take a look at how it works and understand the benefits of using this machine.
