More details on the wide range of experience of Dr. Oswell are provided below, with specific project descriptions following.
Cold Regions Engineering
Dr. Oswell has wide experience in many aspects of northern geotechnical engineering. He has provided onsite inspections and supervision during the construction of an artificial island in the Beaufort Sea, and conducted investigations and prepared geotechnical reports for projects in the Canadian and Russian arctic. He was the primary geotechnical/permafrost engineer for a 76 km offshore pipeline crossing in the Russian arctic. He has been involved in assessing the geotechnical performance of the Norman Wells pipeline for over 15 years. In addition he has provided permafrost engineering on the Mackenzie Gas project, the Alaska Gas project and the Alaska North Slope Gas Project. He also assisted in editing Guidelines for Arctic Foundation Design prepared for the Government of Canada, and was senior author for the report Monograph on Norman Wells pipeline geotechnical design and performance, prepared for the Department of Natural Resources Canada, Geological Survey of Canada. He was also technical manager for the rehabilitation and re-commissioning of a full scale, large diameter pipeline test facility in Fairbanks, Alaska. In the mid-2000s he has been responsible for the design of slopes for the Mackenzie Gas pipeline project, routing and cost estimates for an export gas pipeline near Tambey, Yamal Peninsula, Russia and several other northern oil and gas development projects. Recently Dr. Oswell has been a consultant and member of the Project Management Team for an Alaska natural gas pipeline project.
Offshore Engineering
Dr. Oswell has been involved in numerous offshore development projects. His Masters Degree research focused on shore protection of artificial islands for hydrocarbon development. During the 1980s he was involved in different aspects of the construction of offshore islands in the Beaufort Sea, and supervised the construction of Ellice L-39. Dr. Oswell also provided geotechnical input into the design of large artificial island drilling platforms on the Ob’ River in western Siberia, Russia. He also provided geotechnical and permafrost engineering on a large multi-disciplinary team designing a 76-kilometre undersea gas pipeline crossing in northern Russia. In 1997, Dr. Oswell was responsible for the design for an embankment-fill drilling platform in the tidal flats offshore from India and the review fill placement data for an artificial in the Caspian Sea.
Selected Project Descriptions - Permafrost Engineering
Denali Pipeline Project: Permafrost specialist and member of the Project Management group for the Denali Pipeline Project, which is proposing a 48" natural gas pipeline from Prudhoe Bay to northern Alberta. Provided technical input to routing and geological hazards, and legacy data management.
Arctic Bay, Igloolik and Clyde River NU Waste Water Lagoon Design: Permafrost engineer responsible for addressing the design of the containment structures for sewage lagoons in cold permafrost terrain. Coordinated and managed geothermal modeling of the structures to assess effects on permafrost and geothermal regime, including inclusion of climate warming for a life cycle of 20 years.
Alaska Pipeline Study: Permafrost engineering consultant for a confidential study to examine state-of-the-art thaw settlement design strategies and compile lessons learned and design strategies for the Norman Wells pipeline that could be applicable to a buried pipeline in
Allowable Loading of Heavy Vehicles on Frozen Muskeg: Conducted study for major oil and gas exploration company to assess the necessary thickness of frozen muskeg to support a 68,000 kg (GVW) drill rig. Organized and coordinated field testing and laboratory testing and numerical modeling to determine a preliminary assessment tool for measuring the safe load capacity of frozen muskeg.
Mackenzie Gas Project, NWT: Responsible for the slope design of the pipeline through continuous and discontinuous permafrost. Work involves coordination of multi-disciplinary team (geothermal modelling, geotechnical engineering, GIS) to identify, catalogue slopes and develop design strategies to ensure long-term stability. Other project work included senior permafrost engineer and project manager for planning of geotechnical drilling program for pipeline section south of Norman Wells, and Senior Reviewer for permafrost aspects of EIA. Expert witness in National Energy Board and Joint Review Panel hearings.
Niglintgak Gas Development, Mackenzie Delta, NWT: Senior permafrost engineer and Senior Review Consultant to engineering studies for proposed facilities development at gas field. Provided engineering input to field investigations, conducted on-site QC monitoring of geotechnical investigations, and provided Senior Review of geotechnical reports for various studies.
TambeyNeftigaz Export Gas Pipeline, Yamal
Norman Wells Pipeline, NWT: Senior project engineer with over 15 years of active involvement in geotechnical issues. Responsible for ongoing review and evaluation of thermal, piezometric and slope stability instrumentation. Conducted annual field reconnaissance and inspections, and installed monitoring points. Many of the slopes are experiencing thawing of the permafrost under the pipeline, and an assessment of the stability of the pipeline is necessary. Responsible for preparation of annual stability assessments to be submitted to the NEB.
Ellice L-39
Residential Development, Nizhnevartovsk, Russia: Responsible for planning and supervision of a geotechnical investigation, as well as subsequent analysis and reporting for a North American style community for local production association employees.
Water Treatment Plant,
Group Home,
School, Pond Inlet, NU: Field Engineer responsible for planning and conducting the geotechnical investigation for a high school. The subsurface conditions consisted of moss underlain by fine sand and bedrock. The permafrost table was typically 0.75 m below grade. Suitable foundation systems included insulated spread footings, or rock socket piles.
Hotel and Convention Facility, Igloolik, NU: Project Engineer responsible for planning, undertaking field drilling program, and reporting for a foundation investigation of a Hotel and Convention Facility. Subsurface conditions consisted of fractured sedimentary bedrock, with ice in-filled fissures. Foundation systems needed to address potential thaw settlement issues.
New School,
Fire Hall Reconstruction, Aklavik, NWT: Located in the region of continuous permafrost, buildings with high floor loads require special consideration. This project included the drilling of six boreholes in permafrost and an examination of foundation conditions for the structure that previously occupied the site.
