Fatigue

When low cycle metal fatigue leads to cracks or seam failures, repairing or replacing entire pipeline sections is often required to avoid costly incidents, including leaks, spills, and other threats to the environment and personnel.

To ensure safe access to work areas, TDW provides isolation technology and hot tapping and plugging equipment and services. With products and personnel support from TDW, Offshore Pipeline operators can repair or replace pipeline sections while:

  • Protecting the environment.
  • Protecting personnel.
  • Ensuring product continuity.

In the Offshore Pipeline market, risk reduction is 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. 

TDW technicians, who have a long track record of successful offshore projects around the globe, ensure that the work entrusted to the company is done efficiently with minimal interruption to product flow

Whether operators need an emergency pipeline intervention or topside maintenance during a planned shutdown, HT&P offers safe and proven solutions for getting the project completed. The process incorporates a high 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 when combined with temporary bypass, it allows repairs to be performed without the need to stop product flow. The STOPPLE® Train Plugging System, for example, uses double block and bleed technology to help increase efficiency and safety during pipeline maintenance and repair. The system – which is able to create a double block and bleed seal through a single fitting – 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 creates a safe zone in high-consequence areas.

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. The Subsea 1200RC tapping machine, for example, is a topside-driven hot tap machine that can be safely operated down to a depth of 3,000 meters (9842.5 feet). The machine has proven to be a highly reliable shallow and deep-water solution.

TDW provides non-intrusive isolation technology that enables Offshore Pipeline operators to repair or replace pipeline sections while maintaining full line pressure against the isolation tool.

  • SmartPlug® isolation technology – The TDW non-intrusive, double block and monitor SmartPlug tool is a remotely controlled and operated, non-tethered pipeline isolation system for oil and gas pipelines. It protects people, assets, and the environment while saving time and money compared to the temporary decommissioning of the entire pipeline. In addition, SmartPlug technology enables local hydrotesting of the replaced/repaired area without affecting the integrity of the initial isolation, which can be held in place. The SmartPlug tool also allows production and flow of other lines tied in to the downstream section of the isolated pipeline to continue uninterrupted. 

SmartPlug isolation tools are tracked and identified by the SmartTrack™ two-way communication system. The SmartTrack system accurately tracks, positions, and identifies pigs and tools in thick-wall buried or subsea pipes.
