Removing seized flange bolts with portable machine tools

Removing seized bolts is a frustrating and time consuming process and is fraught with risks to both the machine operator and the components surrounding the bolts. By their very nature, flange joints in the oil, gas and power generation industries are tight, stubborn and difficult to dismantle. But with the right equipment the job can be carried out efficiently and safely.

Here we look at two very different methods of bolt removal and give an insight into the portable machine tools available to carry out the job.

The Casing Double Pin Drill

In our previous blog we told you about our band saw and how it performed during workshop trials. This time we take a look at the DDU1636 double drill unit which was also designed by the Mirage team for offshore decommissioning projects.

In 2012 the Mirage DDU was runner-up product at the World Oil Awards on the ‘Health, Safety, and Environment / Sustainable Development Offshore Award’ category.

The machine is mostly used for drilling lifting holes into casings, which can then be severed using a portable band saw and lifted out of position. The robust construction and carbide tipped cutters makes it an ideal tool for cutting through different materials as used in cemented casing strings.

5 signs why you should invest in a subsea band saw for cold cutting

Posted by Simon Pownall on Jun 2, 2014 12:20:00 PM


Subsea cold cutting of conductors and pipelines can be a risky, arduous and long-winded process, especially in poor weather conditions.

Techniques such as high pressure water jets can be beneficial to your business and the project, but what a saw can offer to a cold cutting solution is far greater.

Here are 5 signs why you should invest in a subsea band saw:
