Field project management and engineering: off-shore gravel islands & facilities, full-scale test sites for thaw settlement, pile/VSM settlement remediation, full-scale pipeline frost heave testing, spray ice islands, vibratory and diesel-hammer installation of large-diameter steel piles and oil-well conductors, installation of thermosyphons to arrest settlement below industrial facilities.Geothermal and Geotechnical Design: on-grade industrial shops on thaw-unstable permafrost, pile/VSM design, workpads and roads, buried, hot oil and gas pipelines in thaw unstable and thaw stable soil, big-inch chilled pipeline frost heave design, horizontally-drilled pipelines in thaw-unstable pipelines, oil-production wellpads built upon thaw-unstable permafrost, multi-season ice pads, buried water and sewer pipes in thaw-unstable permafrost, design of permafrost landfills.Instrumentation: 1000s of thermistor sensor to monitor soil temperatures at full-scale frost heave and pile/VSM test sites, in boreholes along pipeline ROWs, in state-of-the-art soil laboratory equipment, in undisturbed locations to measure the effects of ambient warming on soil temperatures.Design Methodology Development: development of the design methodology for pipeline frost-heave design and pipeline thaw settlement for the > $40 billion dollar Alaska Pipeline Project (Prudhoe Bay to Alberta) and the Alaska LNG Project (Prudhoe Bay to Cook Inlet). The methodologies significantly decreased the number of locations in the field where high pipeline strains were possible.Geothermal Modeling: author of TQUEST, a state-of-the-art computer model designed to simulate 1,2 and 3-dimensional geometries. TQUEST has been used for 100s of projects and has been shown to closely match field observations.Web site: www.northern-engineering.com
