Deep Water ILI Tool Development and 5 Years Operational Experience
The paper describes development of In-Line Inspection (ILI) tools and equipment for deployment in 500+m water depth offshore oil production pipelines. Various design challenges were posed by the operational conditions and the pipeline operator.
A joint development project is described in which 3P Services and Total E&P define the necessary tool characteristics, development and test program.
These challenges included: high pressure tool body design (considering the resulting limited internal space available for on board systems), bi-directional inspection operation capability, ability to negotiate flexible risers without damage to the riser’s internal carcass.
Non tool related developments were also required to prepare a locating device for use in a stuck tool event.
After the successful development, 5 years of operational experience are reviewed summarizing lessons learned and potential for further development.

Pipeline Technology Journal 4/2018
The issue 04/2018 of the ptj focuses on the topic of Offshore Pipelines.
Pipelines are not found exclusively on land. A vast amount of oil, gas and other products is transported through pipelines on the bottom of the seas. These Offshore Pipelines must endure different conditions and require special inspection tools and operating methods to provide a constant flow of the products that keep our industry running.
On it's 68 pages this issue features articles and news from 6 different companies presenting solutions, ideas and products for Offshore Pipelines.
