Pipeline Safety, Reliability, and Rehabilitation
This proceedings,
Ground Attack
Buried surfaces made of concrete, ductile iron and carbon steel are susceptible to corrosion by the soil that surrounds them, but there are numerous ways that these surfaces may be protected....
Probing Pipelines (available only in Geoenvironmental Special Issue)
Inspecting underground pipelines has become easier, more effective and less intrusive through use of sonar, radar, lasers and seismic and acoustic testing. To replace simple visual inspection,...
Making Way for Water
The State Water Project Coastal Branch Aqueduct and Extensions brings 48,000 acre feet of water annually to 23 Southern California communities. built over five years, the project involved...
Nothing Wasted
Anoxic gas flotation (AGF), a patented system for anaerobic digestion of organic slurry waste, can recover as much as 85% of the phosphorus and 23% of the nitrogen in slurry waste, while...
Do Coated Pipes Last Longer?
Field studies have revealed that polymer coated steel pipe resists corrosion longer than pipe coated with other materials. Corrosion is the most common failure mechanism of pipe culvert,...
Pipeline Route Selection for Rural and Cross-Country Pipelines
Prepared by the Task Committee to Rewrite Manual of Practice 46 of Committee on Pipeline Installation and Location of the Pipeline Division of ASCE ...
Pipelines in the Constructed Environment
This proceedings,
Delivered into Providence
The Bristol County Water Authority of Rhode Island needed a pipeline to move potable water into the eastern regions, but the Providence River stood in the way. Directional-drilling provided...
Concrete Colossus
After finding 120 million cubic meters of oil and 30 billion standard cubic meters of natural gas 175 kilometers off the Norwegian coast, Houston-based Conoco, Inc. was faced with a second...
Corrosion Control
As pipe systems with nonwelded joints have become more common, so have problems with corrosion. It's up to designers to carefully consider corrosion issues in order to avoid...
Channel Stability Assessment for Flood Control Projects
This manual provides assistance for determining potential channel instability and sedimentation effects in flood control projects. It is intended to facilitate consideration of the type...
Water Works
The largest water pipeline under construction is in Botswana, in Africa. The North/South carrier project is phase one of a three phase program to bring water to this arid country. Letsobogo...
Fathoming the Strength of Structures
More and more, the owners of bridges and piers are budgeting rehabilitations based on inspections done underneath the waterline. Increasingly, they want the underwater inspectors to be...
Preparing for Repair (Available only in Geoenvironmental Special Issue)
The Sacramento River Water Treatment Plant, Sacramento, Calif., was built in 1924 and hadn't been upgraded since 1958. In 1996, the city of Sacramento, the owner of the plant,...
Pipeline Research Needs
Nature's Payback (Available in Geoenvironmental Engineering Special Issue)
Environmental compensation is now a major concern for utilities and other developers who must compensate for impacting wetlands, streams and other environmentally-sensitive areas. To meet...
Application of High-Resolution Schemes to Free Surface Flows in Irregular Channels
A 1-D flow model employing a high resolution scheme based on the Total Variation Diminishing concept is applied to non-prismatic channels of irregular cross-section. The hydraulic properties...
Efficient Pump Representation for Fixed-Grid MOC in Pipeline Systems
An explicit solution of the pump power failure boundary condition is shown to have many computational advantages over the conventional implicit pump boundary condition solution (i.e.,...
Value Engineering Changes to the Eastside Pipeline
Value Engineering is a process of applying analytic, creative and evaluative techniques to a project in order to make recommendations that will, when implemented, maximize value and quality...
