Hong Kong's Wastewater Underground
Standard Hong Kong methods for siting the new $18 million Stanley Wastewater Treatment Plant in Hong Kong Island's South District were running into trouble. The rocky coastal...
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...
Chesapeake Bay Field Modeling and Monitoring Projects
'Traditional' erosion control measures often do not meet the corps of Engineers' requirement for economic justification. The costs of these measures are much greater than the benefits...
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...
Wave Forecasting for Construction in Mobile Bay
Wave heights were forecast for day-to-day pipeline construction operations in the Main Pass area of Mobile Bay. A low-cost forecasting procedure was developed using the wave generation...
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...
Tackling Trapped Sediments
Crater-sink fluidization has been used to recover sediment from harbors for the past couple of decades. Can this method bypass sediment around dams and return it to eroded beaches, solving...
Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...
3D Frequency Domain Analysis of Offshore Structures
This paper reports the application of three-dimensional (3D) frequency domain computational tools to the dynamic analysis of offshore structure systems. Previous applications of 3D frequency...
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...
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...
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....
A Unified Simulation Approach to Structural System Reliability Analysis
To determine accurate estimates for the system reliability of large complex structures requires considerable computation; unless the problem is assessed in an efficient manner the analysis...
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...
TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...
A Non-Gaussian Fatigue Model for Offshore Structures
Fatigue damage accumulation in members of offshore structures can be affected by various aspects of the non-Gaussian response stress time history induced by the nonlinear/non-Gaussian...
Design of Irrigation Distribution System
This paper briefly discusses the Bureau of Reclamation's process of developing the rehabilitation of the Grand Valley Unit in Colorado. Sections are included on accessing needs of the...
Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...
Applying the ARMOS and MOFAT Models to a Major Oil Spill
A study was undertaken to evaluate the impact of a crude oil pipeline rupture in the recharge area of the aquifer serving most of West Tennessee. The main challenge was to model the volume...
