Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
Response Statistics of Tension Leg Platforms Under Wind Loads
This paper presents the direct integration method and Kac-Siegert technique to solve the first four cumulants in the general quadratic systems, and proposes the splitting technique to...
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...
Advanced Structures in Very Deep Water
Factors which are largely economic will lead to the requirement to design and deploy small numbers of large platforms and large numbers of small platforms in water depths of up to 4 km...
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...
Use of X-Ray Computed Tomography in the Study of Marine Sediments
X-ray computed tomography (CT scanning) is primarily a medical imaging technique. When applied to marine sediments, it responds predominately to the spatial density distribution within...
Internationalization of Engineering Professions
The most salient features impacting the development of our deepwater frontier areas are considered. The areas of higher potential for deepwater reserves are identified. The integrated...
Old Problems and New Challenges in Marine Geotechnical Engineering
The discipline of marine geotechnical engineering originated nearly five decades ago, primarily as a result of the offshore oil and gas industry. As this industry moved into deeper waters,...
Utilization of Waste Materials in Civil Engineering Construction
Industrial growth has increased the volume of wastes generated from energy production, mining, industrial processes and civil works. For economic and related reasons, the use of waste...
Wastewater under Home Plate
A short, highly sloped piping system and peak flows at the start and end of the day were causing the wastewater treatment plant in Daly City, Calif., to frequently exceed its permit for...
Electrokinetic Cleanups
Electrokinetic remediation of contaminated soils is a relatively new research area. Electrokinetic phenomena can be used to create barriers, and move particles, including pollutants such...
Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
Small Utility GIS
Geographic information systems are revolutionizing much of the civil engineering field, providing engineers and managers with a new tool to relate databases and maps. But despite the benefits...
Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...
Instrumenting the `Y'
Segmental bridges are still relatively new to the U.S. and questions persist about their design and behavior. To expand the knowledge base, a number of laboratory and field studies have...
Tensile Terminal
Few can miss a fabric roof that covers a 1.45 million sq ft area. The one covering the Denver International Airport's Landside Terminal complex (reportedly the nation's...
Seismic Assessment of Tailings Dams
A significant portion of the operating and closed large dams in North America are tailings dams used to impound wastes from mining operations. Often these dams were built by mine personnel...
The Caisson Solution
Detroit is expanding its wastewater treatment plant to drastically reduce combined sewer overflows. The expansion, however, is being done on an extremely congested 4 acre tract of land...
Norway's Olympic Cavern
A mountainous task had been undertaken by Norwegian firms in constructing the world's largest in-mountain colosseum for the 1994 Winter Olympic Games in Norway. The Norwegian...
Put to the Test
In the construction industry, the concept of life-cycle cost applies not only to the infrastructure itself, but to the materials that go in to building that infrastructure. To improve...
