The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
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,...
Creep Properties of Ice: Theory and Experiment
In recent years, intensive developments in Northern regions have increased the demand for solutions to a large number of engineering problems involving ice mechanics. In particular, these...
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,...
Effects of External Loadings on Large-Diameter Buried Pipelines
Development of oil and gas resources in the far north has involved extensive use of buried steel pipelines. Buried pipelines, particularly onshore, are frequently subjected to heavy superimposed...
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....
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...
Pipeline Hardware: Special Designs for Arctic Projects
The hardware used to support and protect arctic pipelines has evolved through several years of innovative design work by various engineering firms. The hardware used on the Kuparuk River...
Ice Load Prediction with the Use of a Rate-Dependent Anisotropic Constitutive Law
Man-made structures built in arctic offshore areas are subject to ice loads. Traditional methods for estimating ice loads rely on an indentation factor from rigid-plasticity, an empirical...
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...
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...
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
Maintaining a Natural Gas Pipeline in Active Landslides
This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe...
Methods for Reliability Analysis of Water Distribution Networks
A detailed review of the literature reveals that there is currently no universally accepted definition or measure of reliability for water distribution networks. The purpose of this paper...
Structural Considerations for a Radwaste Facility
The structural engineer needs to consider several criteria when designing a radioactive-waste processing facility in order to properly balance the requirements of safety and economy. This...
Seismic Pope Support Construction Practices
During the mid 1970's the regulatory agencies controlling the design and construction of nuclear power plants began to demand stricter adherence to already existing codes...
Modifications At Operating Nuclear Power Plants
