Soil Cement Shore Protection in Arctic Environment
Suitability of compacted and plastic soil cement prepared with sea water, for shore protection of islands in Arctic marine environment, is investigated. The laboratory test results indicate...
Electrical Resistivity Techniques for Offshore Arctic Geotechnical Engineering Applications
The electrical resistivity of an arctic marine soil depends on the porosity, pore water salinity, grain size and shape, clay content, and degree of ice-bonding of the soil. Therefore,...
Determining Soil Properties by Electric Cone Penetrometer
Gravel island construction is one primary means of establishing permanent locations for oil wells, building foundations and road beds in the arctic. The gravel provides a natural insulation...
Soil Strength Determinations from the Cone Penetrometer Test
Geotechnical exploration in offshore Arctic regions often relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability....
The Rapid Deployment System: A Method for Conducting In Situ Soil Tests from Moving Ice in The Arctic Offshore
A new system was developed which permits rapid helicopter assisted transport of a light-weight in situ geotechnical testing system to remote offshore sites situated on unstable first-year...
Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
The Estimation of Ice Loads From Caisson Deformations Gulf Canada Molikpaq
The Gulf Canada Resources Mobile Arctic Caisson 'Molikpaq' is a bottom founded steel exploration platform capable of year-round operation in the Beaufort Sea....
NPDES Permits for Accelerated Oil & Gas Development
Section 402 of the Clean Water Act (CWA) requires the Environmental Protection Agency (EPA) to develop National Pollutant Discharge Elimination System (NPDES) permits for waste discharges...
Oilspill Response Technology for the Arctic
Alaska Clean Seas is a spill response organization whose area of interest includes all of the marine environment surrounding Alaska. It provides support to members in contingency planning,...
Route Thaw Settlement: A Probabilistic Evaluation
A methodology is outlined for assessing potential differential thaw settlement effects on structures due to permafrost degradation along transportation routes in the offshore, nearshore,...
Arctic Earth Materials for Offshore Construction in Alaska
With the exploration activities onshore and offshore and the development of production facilities, the need for granular earth materials on the North Slope of Alaska is ever present. The...
Offshore Seawater Intake in the Arctic
Waterflood has become a proven technique for enhancing oil recovery from oil producing reservoirs. At Arctic north slope areas, seawater has been used successfully for such operations....
Strength and Deformation Behavior of Frozen Saline Sand and Gravel
Construction of offshore oil and gas exploration and production structures often considers the use of either sand or gravel fill materials. Fill soils exposed to the environment will progressively...
Shear Strength in the Zone of Freezing in Saline Soils
The design of artificial islands and other geotechnical structures to support arctic offshore petroleum resource development requires considerable knowledge of the strength of frozen saline...
Time Dependent Material Properties Due to Solute Redistribution in Frozen Marine Soils
The design of earth structures and foundations in arctic marine environments requires the assessment of soil properties. A study is presented which investigates the change in mechanical...
Endochronic Constitutive Modeling of Frozen Soil
The static behavior of a permafrost type foundation, for a typical artificial island in the Arctic, is determined using endochronic axisymmetric finite element analysis. Endochronic constants...
The Deformation Properties of Warm Underocean Permafrost
Two quasi-conventional incremental pressuremeter tests were carried out on man-made specimens of 'warm' ( minus 3 degree C) frozen, saturated sand. Instead of...
Comparison of Wave Overtopping Prediction to Measurements from Large-Scale Model Tests
A recent large-scale physical model study was sponsored by Arco Alaska, Inc. , to evaluate slope designs for an Arctic offshore oil drilling island. The drilling island will be located...
Wave Runup Around Conical Structures
A variety of conical structures have been proposed for use in the Arctic environment, primarily because the inclined surface of such a structure gives rise to reduced ice loads associated...
Design and Model Testing of an Arctic Seawater Intake for Sedimentation and Wave Effects
A seawater intake structure is being designed to provide flood water for tertiary recovery of oil from the Kuparuk oil field near Prudhoe Bay, Alaska. A wave effects study establishes...
