Seattle Plays It Safe
To ensure the reliability of its aging water system in a major earthquake, the Seattle Water Department commissioned a comprehensive assessment of the system's seismic reliability...
Seismic Hazard Along a Central U.S. Oil Pipeline
An integrated approach is used to evaluate seismic hazards at six sites where pipeline 22 crosses the major rivers in West Tennessee. On the basis of historical and instrumental data,...
Seismic Hazard Analysis for Crude Oil Pipelines in the New Madrid Seismic Zone
The seismic vulnerability of three crude oil pipelines in and around the New Madrid Seismic Zone (NMSZ) is evaluated for a repetition of the 1811-12 New Madrid events. The seismic hazard...
Migration of Spilled Oil from Ruptured Underground Crude Oil Pipelines in the Memphis Area
This study evaluated the impact of an oil pipeline rupture in the recharge area of a West Tennessee aquifer. Two potential break locations were chosen in the alluvial valley of a main...
An Assessment of Environmental Costs Associated with Crude Oil Pipeline Damage Caused by Earthquakes
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks caused by earthquakes. Risk is measured both as volume of oil released and...
Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...

Dallas Goes Trenchless
Dallas Water Utilities (DWU) has stopped relying solely on traditional open-cut trenching methods. Instead, we look to trenchless technologies to minimize costs and disruption to the public....
Overlays on Deck
By the summer of 1993, a standard specification may be on the books for polymer concrete bridge-deck overlays�a high-tech rehab technique requiring a combination of plastic binder�such...

Predicting Fate and Effects of Hydrocarbons in the Oceans
Three major sources of hydrocarbons exist in the oceans. One is from oil spills related to the production and transportation of hydrocarbons. The second, while generally not spectacular,...
Sea Floor Wave-Induced Water Kinematics for Design of Pipeline
A statistical model is presented for horizontal velocity and acceleration of water particles beneath storm seas near the sea floor. An expansion of the kinematics with basis functions...
Reliable Design-Wave Force Predictions for Seabed Pipelines
The results of three separate field research projects have been pulled together to provide a design formula for maximum wave-induced horizontal force on a submarine pipe. This broadly-applicable...
Pipeline Storm Behavior on Clay Soils
A series of transverse wave loading tests was conducted on a specially mounted section of pipe in a sediment-filled tank, to investigate the stability of unburied submarine pipelines under...
Corrosion Fatigue of Deepwater Offshore Materials
Evaluation of the fatigue life of offshore structures operating in depths of up to 10,000 feet (3,048 m) requires knowledge of the combined effect of axial and hydrostatic loading on the...
Homopolar Pulse Butt Welding of API 5L Line Pipe
Homopolar pulse welding (HPW) is a welding process that is being investigated as a means to rapidly join API line pipe, having particularly great potential for application in deepwater...
Effects of Freezing on Impact Properties of RTM Composites, and Their Applications in Offshore Structures
Resin transfer molding is rapidly being acknowledged as the process with potential to create perhaps the purest form of a composite material as representative of the concept of `material-by-design.'...
Fiber Ropes for Ocean Engineering in the 21st Century
Recent advances in synthetic fiber ropes will greatly influence the practice of civil engineering in the oceans during the 21st Century. New fibers have moduli almost as high as steel...
Composites for Offshore Applications: A Multidisciplinary Education Program for the Marine Industry
Composites are increasingly being considered for offshore and other marine structural applications. Polymeric matrix composites reinforced with glass, carbon, and aramids offer substantial...
