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.

The type of subsea problems operators need help with can vary enormously, and with oil and gas decommissioning projects on the increase there will be a huge amount of new machining challenges to face over the coming years.

So what are the kind of projects where portable machine tools have helped to deliver successful outcomes for subsea operators? 

We've put together some examples to provide you with an insight into the typical problems faced and how they are resolved.

Video: Cutting through a heavy wall lower master valve using a split frame cutter

Posted by Alan Hillier on Feb 2, 2016 9:56:29 AM

One of the Mirage split frame pipe cutters was put to the test recently when it was demonstrated at a client’s workshop. Despite the demanding requirement to cut through a heavy material wall thickness of 90mm, the MSF 26-32 performed exceptionally well and the client now uses the machine on their own offshore customer projects.

Take a look at the video to see the split frame cutter in action and if want to find out more get in touch.
