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...
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...
Design and Model Testing of an Arctic Seawater Intake for Sedimentation and Wave Effects
A seawater intake structure is being designed to provide flood water for tertiary recovery of oil from the Kuparuk oil field near Prudhoe Bay, Alaska. A wave effects study establishes...
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,...
Asphalt Revetments for Slope Protection in the Arctic
Experience in the Netherlands demonstrates that slope protection of coastal embankments subjected to heavy wave action can be accomplished with lining systems made of mixtures of asphalt...
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...
Deep-Water Platform Solutions for the Navarin Basin
The environmental conditions prevailing in the Navarin Basin may impose limitations on the type and shape of production, storage and loading structures. The magnitude of the wind and wave...

Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
Use of Rayleigh Waves in Liquefaction Studies
The Spectral-Analysis-of-Surface-Waves method is a new seismic method for efficient determination of shear wave velocity in situ. Vertical impacts applied to the ground surface are used...
Computer-Aided Studies of Complex Soil Moduli
Low-cost microcomputers and new electronic components make it possible to measure accurately the phase and amplitude of mechanical waves in the frequency domain at a small fraction of...
Seismic CPT to Measure In-Situ Shear Wave Velocity
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
Relationships between Shear Wave Velocity and Depth of Overburden
Relationships between in-situ shear wave velocity and depth of overburden have been derived for various Quaternary age soils encountered primarily in Southern California. The geotechnical...
Case Histories: Evaluation of Drilled Pier Integrity by the Stress Wave Propagation Method
The Stress Wave Propagation Method (SWPM) was used to nondestructively investigate the integrity of straight-shaft drilled pier foundations at two sites in the Denver, Colorado area. Drilled...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Simulation of Rock Fracture with the 3-D SHALE Code
The 3-D SHALE code simulates the propagation of stress waves and the occurrence of fracture in brittle solids. The physical models and numerical methods in this code are similar to those...
Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...
Microcomputer Analysis of Harbor Wind Drift
A microcomputer with general-purpose spreadsheet software was used to analyze wind drift on the water surface of Quincy Bay in Boston Harbor. Wind drift is the movement of the surface...
Detection of Leakage Through Subsurface Barriers Using Guided Acoustic Waves
The primary method for preventing hazardous liquid and leachates from entering the groundwater is the use of a physical barrier. These barriers are susceptible to a number of mechanisms...
