Modular Construction with Geosynthetics in Petroleum Industry

This paper focuses on the use of modular construction techniques for installing geosynthetics in petroleum related applications. The petroleum industry uses geosynthetics for drill pad liners, above-ground and in-ground containment ponds, storage tanks, various impoundments including tailings storage, floating covers, road creation and/or support to remote sites, filtration, lining freshwater storage areas, dewatering, and stormwater management. Accelerating the construction of these facilities and the quality, i.e., no leaks, of the installation will have a positive impact on the financial and environmental aspects of the petroleum industry. Modular construction is a process in which a petroleum containment system is constructed primarily off-site, under controlled factory conditions, using the same design, materials, equipment, testing, and construction quality assurance and control (CQA/CQC) techniques as a field constructed facility – but usually in about one-half the time, for significantly less cost, and with few, if any, defects. This is due to the clean and constant conditions present in a factory setting. For example, installation of a factory-fabricated geomembrane can occur simultaneously while site work is being conducted. With factory fabrication, no destructive sampling and testing of the field welds that join rolls of the geomembrane are needed. As a result, a factory fabricated geomembrane can be installed in at least one-half of the time required for traditional field fabrication and with higher quality. This results in the containment system being utilized sooner, being more protective, and creating a faster return on investment.

Towards a Digital Depot to Support Sustainable Manufacturing During Crisis Response

The COVID-19 pandemic has imposed new challenges to maintaining sustainability in our manufacturing operations. With such high variability in demand for urgently needed products (e.g., personal protective equipment, testing technologies) and shifts in the needed capabilities of already complex production systems, sustainability challenges concerning waste management, life cycle impact characterization, and production operations have come to light. An extensive amount of data can be extracted from manufacturing systems, but it is not yet being used to improve the performance of production systems and maintain sustainability strategies during times of distress. This article proposes the concept of a Digital Depot. Being virtual in nature, the depot can contain plans and data for many different types of crises and contain a wider array of products than would be available in a physical, national stockpile. The information could be made available on demand to a national base of manufacturers to help them swiftly pivot to the production of critically needed goods while building on their existing manufacturing capabilities. The contents of the Digital Depot would be applicable to several stages pertinent to manufacturing operations including product definition, production planning information, asset and factory-level data, as well as data concerning the supply chain, distribution, and end-of-life stages. Future work is recommended in the development of templates for robust and secure data sharing, as well as multi-disciplinary identification of businesses cases for data-driven collaborative and sustainable manufacturing practices enabled by the Digital Depot.

Emerging Medical Technologies for Fighting COVID-19: Prevention, Testing, and Treatment (Preprint)

UNSTRUCTURED During COVID-19, the clinical and healthcare demands have been on the rapid rise. Major challenges to addressing the pandemic include a lack of testing kits and shortages of ventilators to treat severe cases of COVID-19, insufficient accessibility to personal protective equipment for both hospitals and the public. New technologies have been developed by scientists, researchers, and companies in response to these demands. In this paper, 90 news articles and scientific reports on COVID-19-related innovations during 2020-2021 were screened and shortlisted to form a pool of candidates yielding a total of 20 publications for review which were then categorized into three sections: personal protective equipment, testing methods, and medical treatments. Each study was analyzed for its engineering characteristics and potential social impact on the COVID-19 pandemic. Finally, the guidelines for future disease prevention, diagnosis and treatment were summarized and discussed.
