Tank Access

When pipeline owners and operators in the industrial and refining markets want access to storage tanks – whether they’re expanding their network, launching a new service, or making another change – TDW can help them through every phase of the project. This work could include tying in new lines, relocating lines, and/or making a pipeline capacity upgrade. The company also can assist with the extensive planning and preparation required for this process.

TDW offers a full suite of services, equipment, and consumables that allows the [insert market] market to:

  • Access the proper tools for each unique operation.
  • Continue product flow while the work is completed.
  • Keep people and the plant safe throughout the project.
  • Keep lines in compliance with company, industry, and regulatory requirements.
  • Consult with TDW experts during any phase of the project.




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 that allow pipeline owners and operators to expand lines, make connections and tie-ins, launch new services, and upgrade capacity – all while their line is in service.

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.

The full suite of isolation solutions offered by TDW plays a critical role in this process. The TDW STOPPLE® Train  isolation system, for example, uses double block and bleed technology to help increase efficiency and safety during pipeline modification. The system – 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 creates a safe zone in high-consequence areas.

Because double block and bleed technology can play such a significant role in protecting people, the environment, and communities, a number of petroleum refineries have made this technology mandatory.

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.
