Concrete Quality Control and Quality Assurance on Strontia Springs Dam
An essential part of the construction management services provided on Strontia Springs Dam was the quality control of material, mixture proportions, and production for all concrete placed...

Geotechnical Features of Fur Seal Island Design
In summer 1983, Texaco made plans to construct an artificial island in Harrison Bay of the Beaufort Sea to serve as a platform for exploratory drilling. Fur Seal Island is to be located...

Arctic Island Construction
The history of island building in the Beaufort Sea of Canada and the United States is reviewed. Construction methods are discussed. These include hauling material from onshore in both...

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...

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....

Ice Floe Impact Force on Vertical Sided Structures
A solution is described that does not assume a contact pressure-area curve or ice crushing strength. The impact force is related to Korzhavin's ice crushing equation by simple...

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,...

The Calculation of Ice Forces on Arctic Structures
Results of tests conducted to determine the relationship between uniaxial compressive strength of ice and crushing force are presented. A plot of normalized uniaxial compressive strength...

Triaxial Compression Testing of Ice
An understanding of the confined compressive strength of ice is needed to develop constitutive equations and failure criteria for analytical ice-structure interaction models. Procedures...

Pioneering Developments in Arctic Dredging
Arctic dredging techniques which have been recently implemented in the Arctic include: the successful hydraulic suction dredging of frozen sands and gravels, the first direct placement...

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...

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...

Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...

Borrow Resource Studies in Near-Shore Areas of Alaska's North Slope
Innovative and cost-effective techniques are utilized in the exploration and analysis of near-shore sources of sand and gravel on Alaska's North Slope. High quality sources...

Ice as a Construction Material in the Offshore Arctic
Ice is the most available and abundant material in the offshore Arctic, and it is therefore one of the most cost-effective construction materials. Over the past decade, ice has been used...

Fatigue Damage for Reinforced Concrete Offshore Structures
When concrete structures are subjected to fatigue loading - resulting from ice or wave loads - progressive damage occurs with increasing number of cycles. Nonlinear damage evolution equation...

Microsilica Concrete: Properties and Applications
With the advent of microsilica concrete, a new generation of high to ultra high strength and high durability concretes have become commercially feasible and are now being specified and...

Low Friction and Adfreeze Coatings
Low friction and adfreeze coatings have proven to be cost effective in reducing skin friction on icebreaker hulls. Of the two coatings acceptable for this service, the 100% polyurethanes...
