Corrosion under insulation imaging with atomic magnetometers

提出了用原子磁强计(AM)的电磁感应成像(EMII)对油气管道的绝缘腐蚀(CUI)进行成像。事实上，目前的技术是危险的、昂贵的和笨重的，例如核背向散射或X射线，或者无法穿透绝缘层，例如太赫兹成像。AM-EMII通过绝缘屏障提供非破坏性的导电性地图和成像。此外，它还具有非接触式、非侵入性、安全性和成本效益的特点。我们计划展示这项技术并评估其在石油和天然气行业的CUI评估中的性能。为此，我们将确定合适的测试结构和案例研究。我们将实现一个用于EMII的系统，并论证CUI检测和2D成像的可行性。针对3D成像而设计的演示器将部署在测试设施中。将继续与潜在的最终用户和利益相关者接触，并将制定商业化进入市场的途径。

We propose electromagnetic induction imaging (EMII) with atomic magnetometers (AM) to image corrosion under insulation (CUI) on oil and gas pipelines. In fact, current techniques are hazardous, expensive and bulky, such as nuclear backscattering or X-ray, or cannot penetrate insulating layers, such as THz imaging. AM-EMII provides non-destructive conductivity maps and imaging through insulating barriers. Furthermore, it is contactless, non-invasive, safe and cost-effective. We plan to demonstrate the technology and evaluate its performance for CUI assessment in the oil and gas industry. To this purpose, we will identify suitable test structures and case studies. We will realise a system for EMII and demonstrate feasibility of detection and 2D imaging of CUI. A demonstrator, designed in view of 3D imaging, will be deployed at the test facility. Continuous engagement with potential end-users and stakeholders will be pursued and commercialisation routes to market will be in place.
