Liquids Recovery

Through a complete line of pigging products, TDW enables Offshore Pipeline pipeline operators to remove liquids and contaminants from wet gas pipelines. Not only does this ensure more consistent production of pipeline raw/unprocessed natural gas and aid in corrosion control, it enhances revenue by enabling the recovery of valuable natural gas liquids (NGLs).



TDW pigging products are designed to help Offshore Pipeline operators efficiently recover natural gas liquids (NGL) from production pipeline systems. Most pigs are equipped with RealSeal® urethane cups – the industry’s most effective seal – for optimal performance and two to three times longer life than regular cups. 

  • UNISPHERE™ pig – Heavy-duty inflatable spheres that remove liquid hydrocarbons and water from pipelines and piping systems.
  • REDSKIN™ foam pig – Tough and abrasion-resistant; used for dewatering, air removal prior to hydrostatic testing, and drying after hydrostatic testing.
  • OptionALL™ batching pig – Designed for light cleaning, line filling and dewatering, batch separation, and liquid removal.
  • VANTAGE® V batching pig – Used for batching, displacing, and light cleaning.
  • ULTRA™ pig – All-urethane pigs that are batching- and displacement-capable.
  • X-Pig® multi-purpose utility tool – Flexible and versatile all-urethane pig can negotiate tight pipeline turns and is appropriate for cleaning, batching, and displacement operations.
  • VANTAGE® + pig – Can be used for batching and displacement; flexible in tight bend pipelines and can traverse a 20 percent reduction in interior pipe diameter.
