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...
The OCEANWHEEL Artificial Island
The compression rim and tension spoke structural system (OCEANWHEEL) transfers lateral loads from sea surface to seafloor efficiently. It promises a wide variety of uses beyond the described...
Modular Construction Technology for Arctic Islands
In order to investigate the possibilities for application in the Arctic of new generation construction vessels, a conceptual design of a production island retained by crane-installed concrete...
Porewater Pressure in Clays Below Caisson Islands
Unfrozen lightly overconsolidated clays are a significant factor in the design and performance of exploration caisson retained islands in the Canadian Beaufort Sea. At two sites (Tarsiut...
In Situ State of Underwater Hydraulic Sand Fills
An approach is described for quantifying the in situ state of hydraulically placed sand fills which are a significant element in the construction of artificial exploration islands in the...
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...
A Contractor Looks at Slope Protection for Arctic Offshore Artificial Islands
Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways...
Arctic Offshore Site Investigations
The continuing search for new petroleum sources has led to increased exploration activity in the arctic offshore regions of Alaska. The general approach to site investigations has been...
A Critique of Arctic Marine Site Investigation Techniques
Arctic marine site investigations have evolved from the need by oil companies to operate in offshore areas beyond the ice shear zone. An overview of the site investigation organization...
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....
Dynamic Global Forces on an Offshore Structure from Multi-Year Ice Floe Impacts
Estimation of global ice forces from ice floe impact against artificial islands and offshore platforms is essential for platform design. The discrete element program, CICE, has been validated...
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...
Ice Forces Due to Impact Loading on a Sloping Structure
Two approximate methods are presented for determining Dynamic Magnification Factors due to floe impact on sloping structures. Some of the physical processes involved are treated simplistically,...
Ice-Structure Interaction of an Offshore Platform
Realistic estimation of the effects of ice floe impact is desirable for the design of certain sub-arctic offshore structures. The results of a preliminary study on dynamic ice-structure...
