Magnetoquasistatic sensors for rapid imaging of steel pipeline properties
… solution for imaging the metallic properties of pipelines. The target problem addressed is rapidly imaging pipeline steel thickness through thick insulation and weatherjacketing materials in order to detect areas of corrosion. The following bullet points outline the advancements in sensor design, …

Application of superparamagnetic nanoparticle-based heating for non-abrasive removal of wax deposits from subsea oil pipelines
… hydrate and wax deposits on the inner surface of pipelines. Commonly used methods for removal of deposits from pipelines are chemical injection and foam or gel pigs, which face several limitations. In our work, an application to use superparamagnetic nanoparticle-based heating for flow assurance, …
