A Binary Fluid Ejector (BFE) refrigeration system is a scalable, energy efficient, cost effective, environmentally friendly refrigeration system that converts thermal energy directly into cooling. The intern will be performing feasibility studies of potential practical applications for the BFE system based on the different climate zones in North America.
Pile foundations have been widely used in many offshore structures and oil and gas development programs such as tension leg platform, jack up platform, spar platform, and mooring of floating production, storage and offloading units (FPSO) units. The FPSO units are usually moored to the seabed with various kinds of anchors, including offshore piles. These piles are subjected to inclined upward load from FPSO. The objective of this research is to develop advanced method to estimate load carrying capacity of offshore mooring piles in sand subjected to inclined loading.
The project will research software and models of plume migration for subsea oil and gas productions. Plume migration is important because when a leak takes place subsea, it needs to set off a sensor, and to do that for point sensors, the product must come near the sensor. Knowing how oil will move under water will help the placement of sensors and improve overall leak detection of the system for any given environment. Another aspect of the project is to develop a lab model for testing leak detection technologies.
Crosswell seismic tomography is a geophysical survey method in which the propagation of sound waves through the Earth’s crust is used to infer geological structure. An array of acoustic sources and receivers are placed into two separate boreholes, and full waveform recordings are made of the response to each source, measured at each of the receivers, the objective being a ―cross-section‖ of the geology between the two boreholes. Two attributes are extracted from this survey: i) the measured arrival times, and ii) the frequency domain components of the waveforms.
Onshore and offshore pipe systems may be subject to loading events that result in mechanical responde exceeding the material strength. There are technical and economic incentives for developing non-conventional, higher strength materials for use in long distance, large diameter and high pressure transmission pipeline systems. There exists uncertainty on the key factors influencing the mechanical response of these materials in pipe systems subject to large deformation loading events. This study will develop an analytical tool that can be used to assess the pipe mechanical integrity.
Fiber-reinforced polymer composites (FRPC) have long been recognized for their high strength-to-mass and stiffness-to-mass ratios and excellent corrosion resistance. Certain emerging technologies in the oil and gas industry do not permit the use of metallic structures, and FRPC are therefore considered as an alternative. Conventional polymer materials are usually not capable of sustaining the environmental conditions that exist for the considered applications, which includes temperatures in excess of the boiling point of water, and exposure to hydrocarbons and water.
