The paper describes development of in line inspection tools and equipment for deployment in 1500+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 the pipeline operator 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.
