Third-Party Damage

Third-party damage is a leading cause of damage to pipelines resulting in dents, cracks, gouges, etc. This damage, if not addressed, can eventually lead to pipeline failure.

TDW offers a full suite of solutions to help pipeline owners and operators find, assess, and repair third-party damage. In the Hydrocarbon Processing industry, these services enable operators to:

  • Ensure the pipeline is clean prior to deploying any inline inspection technology.
  • Inspect the pipeline and provide details on integrity concerns.
  • Pinpoint damage and prioritize repairs.
  • Restore the pipeline to operating condition.
  • Save time and money through minimally invasive technologies.
  • Avoid bleeding down the entire pipeline.
  • Quickly and safely mitigate risk to personnel and the environment.

Pigging assists Hydrocarbon Processing operators in assessing non-emergency third-party damage by cleaning the online or offline pipeline prior to evaluation with inline inspection (ILI) tools, helping to improve data capture and giving operators the most accurate information about necessary repairs.

In addition, as isolation operations are often necessary to facilitate the repair of third-party damage, pigging prior to the isolation is essential to success. By removing built-up liquids, contaminants, and deposits on the pipe wall, operators can help ensure first-time success and a flawless isolation – which translates into a quicker turnaround and less downtime.

  • VANTAGE® V cleaning pig – Multi-use pig designed to remove both hard, crust-like and soft, gummy deposits, as well as ferrous materials.
  • WCK cleaning pig  – Removes contaminants and deposits that increase resistance to flow.
  • REDSKIN™ foam pig  – Used for light cleaning; one version incorporates a urethane cleaning wrap with bypass groove that effectively removes paraffin and other soft deposits that could lead to corrosion.
  • UNISPHERE™ pig – Provides heavy-duty removal of liquid hydrocarbons and water from pipelines and piping systems.

Technical assistance is available from TDW subject matter experts for special circumstances or if the path to a solution requires consultation.

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 a wide array of pipeline defects and maintenance challenges from dents to corrosion to valve failure.

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 needs work has been safely isolated and evacuated, the line modification can be performed.

TDW isolation technology plays a critical role in this process, and a temporary bypass allows 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, they can rely on the TDW line of equipment and consumables. TDW application engineers are recognized industry experts, ready to assist operators through each project phase – from start to finish.
