3P Services is an experienced specialist in the field of in-line inspection services on land and under water. The company’s focus lies on challenging pipelines and loading lines are a part of it as they require special technologies to be inspected.

In many pipelines there are no facilities to launch or receive ILI (In Line Inspection / Smart Pigging) tools. If only one end is accessible, then a bi-directional operation is the way to go.

Bi-directional inspection tools require special design that affects various mechanical, sensor and electronic related elements. They must be able to run and inspect forward and backwards.

3P Services introduced the concept of free swimming bi-directional inspection tools to the industry more than 20 years ago. With this technology 3P Services records measurements while traveling in both directions. Therefore, a double inspection coverage is achieved. This supports the data analysis process and brings a powerful boost to the confidence in the accuracy of the inspection data.

Key Advantages of this Technology

  • Generally no restriction to range or pipeline length
  • No restriction to the number of bends present in the line
  • Short radius bends, usually down to 1.5 D, and back to back bend combinations are not obstacles

Typical Applications

  • Coastal tanker loading and unloading terminals where the offshore end of the pipeline ends on the sea floor
  • Offshore flowlines, where platform risers may not be passed by mechanical steel bodied tools (e.g. due to sensitive flexible risers)
  • Typically in all pipelines where access to one end is very limited.

3P Services specialize in providing state-of-the-art in-line inspection of pipelines and other structures transporting and storing hydrocarbons or other liquids and gases used in the petroleum, petrochemical or chemical industry. Their technologies reliably identify threats and anomalies and provide the necessary metrics to counteract and eliminate material defects at an early stage. This requires flexible and responsive tool design and construction processes. Quite often special configuration, even new-build, tools are prepared for a single pipeline inspection – and this is achieved within lead times and budgets
