Trenchless Diversity Fuels Growth of Construction Activities
This paper describes a variety of trenchless technology methods of reconstructing America's decaying pipeline infrastructure by using minimum and /or 'no-dig processes'. The decay of our...
An Ongoing Field Study to Evaluate the Impacts and Direct Effects of Offshore Dreding Activities on Benthic Organisms
Instrumentation and sampling involve box coring, otter trawling, the use of a towed sled carrying video camera, and a sidescan sonar device. The baseline collection phase of the study...
Influence of Lateral Wind on Driving on Offshore Bridge
The Honshu-Shikoku Bridges are a system of highways crossing over the sea, where cross-winds variously affect vehicle behaviour. This is the intermediate report on the surveys aimed at...
ECOR, an International Organization Active in the Coastal Zone
The Engineering Committee on Oceanic Resources is an international organization that fosters and facilitates cooperation in the field of ocean engineering. The purpose of ECOR is: (a)...
Core and Reaming Bit Studies in Yucca Mountain Tuffs
The Site Characterization Project is a major part of the work in determining the suitability of Yucca Mountain as a potential high level waste repository. Over 100 exploratory drill holes...
Dredged Material Filled Geotextile Containers
Design and construction of geotextile containers hydraulically and mechanically filled with a variety of dredged material types has gained popularity in the past few years because of their...
Quarry Techniques for Dimensional Breakwater Stone
On the Texas Gulf Coast, there has evolved a unique design for breakwater and jetty structures. The Galveston District of the U.S. Army Corps of Engineers, the designer of these structures,...
Progress and Developments in Dam Rehabilitation by Grouting
Recent Progress in American Pinpile Technology
An Overview of Segmented Offshore/Headland Breakwater Projects Constructed by the Buffalo District
Since 1977 the Buffalo District has constructed three segmented offshore breakwater projects and currently has one under construction. In addition, the District has recently completed...
Bay Ridge, Anne Arundel County, Maryland Offshore Breakwater and Beach Fill Design
Construction of the Bay Ridge shoreline protection project was completed in July 1991 and consists of eleven offshore segmented breakwaters with beach fill. The breakwaters, located about...
Case Study of an Offshore Horizontal Boring
A pipeline system was needed to transport natural gas from a discovery in Mobile Block 823 to Mobil's existing system inside Mobile Bay. Sand Island, a small barrier island off Dauphin...
Environmental Effects of Beaufort Sea Causeways
Two gravel-fill causeways have been constructed into the shallow nearshore Beaufort sea on the north coast of Alaska for the development of petroleum reservoirs. These long (4-8 km) structures...
Responses of Bilinear and Impacting Systems Subjected to Regular Waves
The dynamic responses of bilinear and impacting oscillators subjected to harmonic loadings are investigated. Differing from previous studies in which bifurcation diagrams were developed...
Mass and Energy Tradeoffs of Axial Penetration Devices on Lunar Soil Simulant
Axial penetration of the lunar surface was performed to collect soil samples with drive tubes and drill cores on the six successful Apollo missions. Although the pile-driving and drill...
In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...
The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...
Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...
Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....
Offshore Pile System Reliability
The existing design methodology for offshore pile foundations is evaluated relative to the ultimate performance of the foundation system using reliability techniques and data from three...
