Tanker Mooring/Loading Systems for Northern Offshore Arctic Regions
Transportation of crude oil in arctic areas via shuttle tankers can prove to be a viable alternative to a pipeline system. The shuttle tanker system will require offshore terminals equipped...
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...
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...
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,...
Probabilistic Description of Ice Forces on an Offshore Arctic Structure
A probabilistic simulation model has been developed to describe the frequency and outcome of multi-year ice floe encounters with a fixed offshore structure located in the Beaufort Sea,...
Selection of Environmental Design Criteria for Arctic Structures
Where data are insufficient for calculation of extremes using probability theory, design criteria may be reasonable defined by combining available data, knowledge of physical processes...
Probabilistic Approaches to Arctic Offshore Engineering
The arctic offshore environment poses challenges in design, site construction, and operation that range from the problems associated with large ice forces, to those of short open-water...
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,...
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...
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...
Santa Fe's Mobile Arctic Drilling Barge
There is a need for mobile units that can operate year-round in shallow Alaskan waters south of the Bering Strait for exploratory drilling and/or early production. Santa Fe has completed...
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...
Constructibility of Arctic Offshore Structures
The costs of structures designed for Arctic Offshore Drilling and Production Platforms have reached extreme levels. A major component of the costs of such structures is their constructibility....
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....
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...
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...
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...
The Sand Mattress Method of Slope Protection
The sand mattress concept offers promise as an economical alternative to sand bag armor for two distinct applications: (1) slope protection for exploratory islands and/or causeway facilities,...
