Overview of Artificial Island Design and Construction in the Arctic
An overview is provided of the design and construction of artificial islands in the Arctic. Since the early seventies more than 20 islands have been constructed in the Alaskan and Canadian...

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...

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...

Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...

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...

Environmental Permitting Approaches for Future Development of Offshore Oil Fields in the Arctic
Environmental impact of petroleum prospecting on the North Slope of Alaska is complicated by climatic problems of long periods of low temperature and thick ocean ice. Better engineering...

Bowhead Whales and Other Endangered Whale Species: Their Influence on Offshore Operations in Alaska
In recent years, whales have become the focus of considerable public concern, and this is manifested in the measures that are imposed to protect them from possible adverse effects of offshore...

Spatial Analysis of Ice Charts
Spatial approaches to ice environment modeling can not only lead to better local hazard predictions but also produce regionalizations that are useful for construction, navigation, and...

SHADS: Mobile Arctic Drilling Platform
To minimize costs of Beaufort Sea exploration programs, the industry needed a mobile arctic drilling structure that requires little or no site preparation, does not require an active ice...

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...

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...

Three-Dimensional Analysis of an Artificial Island
A nonlinear, finite element analysis has been carried out to investigate the influence of three-dimensional loading and geometry on deformation and failure of an artificial island. The...

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...

Technical Considerations for Beaufort Sea Pipelines
The development of Beaufort Sea fields requires construction methods and equipment for pipeline installation and trenching providing a balance between safety, reliability, and economy....

Directional Drilling to Install Arctic Marine Pipelines
Directional drilling for offshore Arctic pipeline construction offers essentially year-round construction performance capability. The most readily acknowledged alternate candidate construction...

Pipeline Landfall Construction by Horizontal Drilling
The segment of an offshore pipeline where the transition is made from standard offshore laying procedures to standard on land laying procedures represents a difficult and costly construction...

Fracture Theory for Nonhomogeneous Brittle Materials with Application to Ice
Brittle heterogeneous materials generally fracture with a dispersed zone of microcracking at the fracture front. The deformation and failure of these materials can be described by a nonlocal...

Validation of the CICE Code for Ice Ride-Up and Ice Ridge Cone Interaction
The discrete element method is capable of analyzing multiple, interacting, deformable, discontinuous or fractured bodies undergoing large motions and rotations. The formulation solves...

Bering Sea Crude Oil Transportation Systems
A study to evaluate and compare the technology and costs associated with crude oil transportation alternatives in the Bering Sea has been conducted. Existing and proposed offshore loading...
