TECMA and Baker Hughes have been actively involved in supporting ENI in the development of the “Carbon Capture & Sequestration (CCS) pilot project”.
In order to re-use the existing infrastructure for CO2 transportation in CCS Demo project in Ravenna (Italy), the feasibility to insert a new 4” X65 pipeline into an existing 20” X52 pipeline was evaluated. The existing pipeline acts as casing and thus minimizes environmental impact, facilitates permits request, and provides an external extra-protection.
The initial request was to get accurate geometrical data from the existing 20” pipeline in order to reuse it as a conductor for the new pipeline pulling project, with particular focus on pipeline routing and bends geometry with the objective to confirm the fit for purpose and to plan the pulling process of the new 4’’ pipeline. TECMA and Baker Hughes were tasked to engineer and provide an “intelligent pig system” as compact and smart as possible capable to characterize the pipeline bends, in terms of minimum bend radius, angle and position, along the overall pipeline route (onshore and offshore).
Using the latest ILI technology, TECMA proposed to employ a multi-technology inspection vehicle instead and was able to provide data that helped ENI to re-evaluate the integrity of the existing 20" pipeline and to re-use it as the main CO2 carrier.
