Since the introduction of inline inspection (ILI) tools more than 50 years ago, there have always been pipelines that were considered unpiggable. At ROSEN, however, we refuse to accept this as a fact. This is why we have dedicated the Challenging Pipeline Diagnostics Division to finding ILI solutions for what we refer to as challenging pipelines.
In working closely with our customers, it often becomes clear that it is not simply one hurdle that prevents the use of traditional inspection equipment and technologies. Commonly, the complication lies in the combination of various circumstances which must be overcome. Issues directly arising from these assets often refer to accessibility, negotiability, and operating conditions. Further challenges relate to pipeline cleanliness, tool tracking, and risk mitigation. Though challenges vary from one pipeline to the next, the most common include:
- Access or passage restrictions related to pipeline design, e.g. bends, length, T’s, absence of launchers and receivers, etc.
- Condition of the pipeline, e.g. pressure, ﬂow, cleanliness, etc.
- Properties of the product being transported, e.g. temperature, liquid, gas, multi-phase.
As each challenge is unique, building a specific tool for each solution is not feasible. Therefore, a flexible approach is needed that can be adapted to each individual case.
The key to an optimal solution is the toolbox approach. It consists of complementing units, such as technologies, methods, and market knowledge, which together enable solution experts to optimally address each challenge. We aim to provide tailored solutions that not only give operators the means to have the pipeline inspected, but also, when desired, to provide a comprehensive integrity assessment.
With access to the most advanced technology of today, and the experience resulting from successfully inspecting over 160,000 kilometers of pipelines per year, our Challenging Pipeline Diagnostics Division is well-equipped to explore solutions aimed to tackle a wide range of challenges.
Our competence is built on more than three decades of company experience in the inline inspection business, resulting in a wealth of knowledge that allows us to understand the special requirements of successfully inspecting challenging pipelines.
