NES Expertise

NES’s projects have included analysis and design large-diameter cold-gas pipelines in frozen and unfrozen soils, passive and active soil freezing projects, design of laboratory soil test cells, hot-oil and slurry pipelines in frozen and unfrozen soils, soil freezing to block contaminate transport, landfills and utility projects in permafrost and seasonally freezing soils.

Project Management

NES is known for efficient project management and efficient field engineering of small projects, like geotechnical drilling projects, projects like shown in the photos above, and for large projects like field coordination of mega-projects like Pioneer’s off-shore gravel island and their on-shore and off-shore facility construction.

Engineering Analysis

NES is the author of TQUEST, a state-of-the-art geothermal model for simulations of 1-dimensional, 2-dimensional planar or axisymmetric and 3-dimensional geometries.  TQUEST was formulated to model materials that have highly non-linear properties, such as geotechnical problems involving latent heat of fusion and vaporization.  TQUEST is fully supported with tools developed by NES, including a cad-based a finite-element grid generator and presentation tools.

Technical Papers, Conferences and Workshops

NES has written many technical papers on a wide-range of (mostly) permafrost-related topics and has presented papers at many conferences and workshops on the general topic of the effect and how to adapt engineering designs to changing/warming climate in sub-Arctic and Arctic regions. Most recently he was the keynote speaker on “Geotechnical Engineering and Design for Warming Soil Conditions” at the International Cold Regions Canadian Permafrost Conference in Quebec (Click HERE for the Keynote).
