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...
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...
Soil-Pipeline Interaction During Ground Movement
The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement....
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...
Overview of Soil and Engineering Geologic Conditions in the Beaufort, Chukchi, and Bering Seas
General soil and engineering geologic conditions that are likely to affect exploratory drilling and development activities in six Alaska OCS lease sale areas are discussed. Important conditions...
North Sea Technology Transfer to the Bering Sea
Concrete platforms in the North Sea are reviewed, including technological considerations and economic factors involved in their selection and application. The applicability of this technology...
Structural Solutions for the Enhancement of Gravity Foundations on Very Soft Arctic Soils
Very soft soils in several offshore Arctic areas cause a major concern in the design of gravity foundations, particularly in view of the high magnitudes of ice loads. Preliminary studies...
Stochastic Finite Element Analysis of Gravity Platform Foundation
Gravity foundation design requires determination of total and differential settlement, vertical stress distribution beneath the raft and maximum shear stresses in the sand layers in the...
Thaw Settlement as a Result of Permafrost Deterioration
An overview is given of floor and footing failure as a result of deterioration of permafrost. Consideration of causes for the deterioration and methods of repair are addressed in general...
Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...
Developing a Drilling Structure for Arctic Waters
Fluor-Doris of Houston has developed a mobile, composite concrete and steel drilling structure called the Arctic Composite Platform (ARCOP). This platform is capable of operations in water...
Concrete Space Frame Applied to an Arctic M.O.D.U.
The BOUYGUES experience in the use of concrete space frame technology for civil works and the application of this technique, combined with high strength concrete and prefabrication, to...
Jumbo Modules for Artificial Islands
The development of the Arctic Offshore oil fields has led to the consideration of gravel islands or other structures to support oil production facilities. The island and the assembly site...
Research Challenges in Frozen Ground Pile Design
A fairly recent pile design analysis is reviewed. The influence of such factors as temperature, salinity, loading, etc. on frozen ground pile design is pointed out. Since many facets of...
Coastal Erosion's Impact on California Offshore Oil Development
Recent oil discoveries in the offshore Santa Maria Basin and the Santa Barbara Channel will require the construction of new oil facilities located along 90 miles of Santa Barbara County...
Stochastic Beams on Elastic Foundation
The finite difference method is applied to the second-moment analysis of beams on elastic foundation with random characteristics. The method is simpler than the stochastic finite element...
Arctic Foundation Selection: A Decision Matrix
An idealized matrix diagram is presented of the decision making process involved in determing an economic Arctic foundation type that is best suited to the proposed above-grade structure....
Attenuating Creep of Piles in Frozen Soils
Results of several long-term creep tests of piles in frozen soils are analyzed; the primary or attenuating creep is predominant in most cases. For effective design of pile foundations...
