The process of taking a pipeline out of service involves more than halting product flow. Before abandoning a line, operators must ensure that it is safe and in full compliance with regulatory and industry requirements.
Abandoning a pipeline is a multi-step process that typically includes disconnecting the line from the product source, removing product, cleaning, and, in some cases, segmenting and capping the line. TDW subject matter experts can guide operators through this process and recommend solutions, from pigs that can push out liquids and clean the pipeline to hot tapping and plugging services that facilitate line modifications.

In the Hydrocarbon Processing market, where hundreds – or thousands – of employees often work in close quarters and capital investments may be in the hundreds of millions – or even low billions – of dollars, safe pipeline repairs are of utmost importance. TDW offers safe, proven hot tapping and plugging (HT&P) solutions for safely discontinuing line service – while ensuring that the line is left in full regulatory compliance.
The HT&P process incorporates a low pressure pipeline fitting, valve, tapping machine, and isolation equipment – all working together to provide a safe and proven isolation solution. Once the area of pipeline that requires work has been safely isolated and evacuated, the line modification can be performed.
TDW isolation solutions play a critical role in this process: they allow work to be performed without the need to stop product flow. The TDW STOPPLE® Train isolation system, for example, uses double block and bleed technology to help increase efficiency and safety during pipeline modification. This approach to line isolation, which only requires a single pipeline tap, reduces costs associated with fittings, valves, welding, and inspection services. The bleed port affixed on the line ensures that any product that bypasses the first seal is contained and evacuated through the bleed port, which helps operators better protect people and the environment.
Whether operators are purchasing equipment to perform their own HT&P jobs or turning to TDW to execute the service for them, they can rely on the broad line of equipment and consumables that the company offers. TDW engineers and manufactures nearly every component needed for an HT&P project, and TDW tapping and plugging machines are considered the industry standard.
TDW can also partner with operators before the work begins, providing consulting services to help them make optimum use of TDW products and services. TDW application engineers are recognized industry experts, ready to assist operators through each project phase – from start to finish.
