3 decommissioning machine tools to create casing lift holes

Posted by Alan Hillier on Jan 16, 2019 1:05:00 PM

 

 

As many offshore oil rigs reach the end of their life, the need for portable machine tools to assist with decommissioning is set to increase. One example of a difficult challenge faced by decommissioning engineers is the need to sever and lift caissons or casings - often in very difficult and extreme working conditions. Finding the right equipment to carry out these operations efficiently and safely isn’t easy – which is why the Mirage design team have designed three types of casing pin drills for different situations. Let’s take a look at these three machines.

With a new year just beginning and the holiday period behind us, we begin to see industry publishers sharing their thoughts on what the new year might bring for us. The on-site machinist's work may span several different sectors – each with their own different take view of the future. Take a look at the highlights we've gathered from around the web,  and make up your own mind whether 2019 will be challenging, uncertain, or be a good year that brings new opportunities.

How Crude Oil is separated into fractions

Posted by Alan Hillier on Nov 28, 2018 9:02:00 AM

If you're an on-site machinist, you may be expected to work across a variety of industries - often carrying out in-situ jobs such as flange facing, hot tapping or pipe cutting. It goes without saying that the most important thing is to get the job done efficiently and effectively. But if you can demonstrate your knowledge of what goes on at the plant then your credibility can be enhanced - potentially leading to more work in the future.

Oil refining plants create a huge amount of on-site machining work,  so having a grasp of the main process involved will put you in a good position. The graphic we've created for you below shows the principle behind a fractionating column used to refine crude oil.

How flange alignment and flange closing tools work

Posted by Alan Hillier on Nov 14, 2018 2:09:00 PM

 

ln our previous article we looked at flange spreaders, so continuing the theme we now take a look at flange alignment and flange pulling tools.

Flange alignment tools are used to align or re-align flange joints during pipework construction, commissioning or during routine maintenance. This might be when replacing an RTJ of ring or when the flange face needs re-machining using a flange facing machine.

Once broken down, a previously assembled flanged joint may spring out of alignment at any point or in any direction around its circumference. Misalignment may not be visible until only a few bolts remain.

Flange spreading tools and how they work

Posted by Alan Hillier on Nov 5, 2018 3:05:00 PM

 

Flange spreading tools – (sometimes referred to as flange splitters or flange separators), are a useful addition to the on-site engineer’s arsenal of flange maintenance tools. These industrial tools are available in a range of configurations, and as the name suggests they’re used to assist in the separation of pipe flange joints. Typical projects include pipeline construction, commissioning, routine maintenance or when valves or pumps need to be replaced.
