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...
Cyclic Multiaxial Cubical Cell Experiments on a Norton Sound Silt
A servo-controlled multiaxial cubical test apparatus has recently been used to investigate the behavior of the foundation soil for a gravity structure in Norton Sound of the Alaska Outer...
Arctic Oil Spills in Relationship to Sea Ice Motion
Sea ice on a scale of a few kilometers must be treated as a granular material rather than a continuum. The floes are in nearly constant motion relative to a fixed frame and each other....
Deep Water Bering Sea Development Concepts
A brief description of the major environmental factors that a structure used to produce oil and gas in the deep water Bering Sea would have to cope with is presented. In particular, the...
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...
Single Point Moorings for the Bering Sea
Multi or single-legged buoy systems such as conventional CALMs or SALMs would not survive the winter season in the Bering Sea because the forces generated in the anchoring chains by pack-ice...
Improving Arctic Seafloor Soil Stability
Soft, low strength soil layers at or beneath the Beaufort seafloor mean that soil strengthening may be necessary to ensure the stability of oil exploration and production structures under...
A Beaufort Sea Deepwater Production Structure
There will be a need for large crude oil production platforms in Beaufort Sea water depths between 20 and 50 m and at locations with soft seabed soils and far from readily exploitable...
SAV Reestablishment Results?Upper Chesapeake Bay
In the Susquehanna Flats area of the upper Chesapeake Bay, six submersed aquatic plant species were used to test the feasibility of transplanting SAV into sites which were previously vegetated,...
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...
MILHY?A Microcomputer Based Hydrologic and Hydraulic Model
MILHY is an interactive, single event, lumped parameter model used to estimate streamflows and water surface profiles. The model was designed for use on basins less than approximately...
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...
Initial Operation Model for the Central Arizona Project
A microcomputer program for operating uncompleted portions of the Central Arizona Project has been developed. Engineers may use this program daily to assist in scheduling pumping plant...
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....
Snow Effects on Pile Design Temperatures
The construction of North Slope aboveground pipelines and gathering lines is generally from snow workpads constructed proximate to existing access roadways. The pile support centerline...
Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...
