Availability estimation and management for complex processing systems

“Availability” is the terminology used in asset intensive industries such as petrochemical and hydrocarbons processing to describe the readiness of equipment, systems or plants to perform their designed functions. It is a measure to suggest a facility’s capability of meeting targeted production in a safe working environment. Availability is also vital as it encompasses reliability and maintainability, allowing engineers to manage and operate facilities by focusing on one performance indicator. These benefits make availability a very demanding and highly desired area of interest and research for both industry and academia. In this dissertation, new models, approaches and algorithms have been explored to estimate and manage the availability of complex hydrocarbon processing systems. The risk of equipment failure and its effect on availability is vital in the hydrocarbon industry, and is also explored in this research. The importance of availability encouraged companies to invest in this domain by putting efforts and resources to develop novel techniques for system availability enhancement. Most of the work in this area is focused on individual equipment compared to facility or system level availability assessment and management. This research is focused on developing an new systematic methods to estimate system availability. The main focus areas in this research are to address availability estimation and management through physical asset management, risk-based availability estimation strategies, availability and safety using a failure assessment framework, and availability enhancement using early equipment fault detection and maintenance scheduling optimization.

Re-mapping the body: feminine experience in music performance

In this project report I analyse how the practice of Body Mapping impacts the bodily performances of women classical musicians. The purpose is to study how the characteristics that define normative gender affect the body and its movement; to interrogate the body as the site where a patriarchal society constructs gender roles (more specifically, femininity); and consequently to assess the effects that these may produce in music performance. Drawing on interviews with six women classical musicians, autoethnography, and Body Mapping as a method, I created a workbook for women Body Mapping students. The goal of my research is to look into the possibilities of how the three fields—music performance, Body Mapping and feminist thought—can connect together, thus laying the groundwork for possible future research in this area. Even more, I seek to apply new approaches to music performance and to contribute, at a practical level, to the development of women classical musicians.
