The Effect of Nonlinear Drag PSD on Fatigue of Compliant Offshore Structures
Structural fatigue damage induced by random ocean wave loading on a compliant type of offshore structure is considered. The nonlinear wave force is modeled by the Morison equation and...

Fatigue of Floating Offshore Structures: Modelling Uncertainty in Hydrodynamics and Fatigue Properties
For floating offshore structures such as tension leg platforms (TLPs), one form of loading uncertainty is due to nonlinear diffraction forces, which can excite lightly damped vertical...

Time Variant Reliability Under Environmental Loads
Time variant reliability with deteriorating resistance under a stochastic load process is considered. An outcrossing formulation for fatigue degradation is presented, and a simple and...

Global Approaches for the Nonconvex Optimization of Pipe Networks
Because the pipe network problem is nonconvex, two global search schemes, MULTISTART and ANNEALING, are employed to permit a local optimum seeking method to migrate among various local...

Pipe Network Optimisation Using Genetic Algorithms
A new optimization technique of generic algorithms has recently been successfully applied to pipe network optimization. In this paper a parametric analysis is carried out of the genetic...

Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...

Optimal Rehabilitation Model for Water Distribution Systems
The objective of this paper is to describe a new methodology which can select the pipes to be rehabilitated and/or replaced in an existing water distribution system and determine how much...

Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...

Global Distribution of Water Through the Oceans
The paper is a conceptual investigation of a pipeline and bladder system for conveying and storing fresh water in the oceans. Modeling is recommended to provide background on what could...

Water Pipelines: Tackling Toxics
In the spring of 1988, residents of Girwood, Alaska contacted the state's environmental agency to complain of foul-tasting drinking water. While most complaints came after...

The Megabight Barrier / Maglev Way?Innovative Siting of High Speed Ground Transportation...Offshore
Air and road traffic congestion around cities, e.g., in the BOSWASH corridor, can be reduced by high speed rail systems. But high speed trains on elevated rails/guideways encounter extra...

Energy Facility Siting in Coastal Zones
Siting constraints to the development of coastal energy facilities may lengthen or complicate the siting process. These constraints have evolved over the history of coastal energy facilities....

Coastal Management and Ocean Industries in East Germany, from Central Planning Ineffectiveness Towards Local and Regional Development Strategies
In so far, the preconditions for the implementation of decentralized development tools both in coastal management and in ocean industries may be quite ideal in East Germany: there is the...

The Value of the Federal Oil/Gas OCS and Its Required Nexus with the Changing Perceived Quality of Rights
A particular few of thousands of hardly distinguishable and certainly previously undistinguished Federal OCS oil/gas tracts can suddenly become prizes of great value. Vice versa, prized...

Environmental Compliance and Offshore Oil and Gas Exploration and Production
The economic impacts of multiple environmental regulations of offshore oil and gas exploration and production are examined using an integrated, investment-production-regulatory model developed...

Modern Air Pollution Reduction Technology on Platforms in the Pacific OCS
The Pacific Outer Continental Shelf (OCS) along the California coast line has the most sophisticated air pollution reduction technologies implemented in the world. This paper describes...

The Whole Picture: Federal Statutory and Regulatory Authorities Which Govern Oil and Gas Activities on the Alaskan Outer Continental Shelf
Oil and gas activities conducted on the Alaska Outer Continental Shelf (OCS) are subject to multiple Federal laws which result in safe operations and environmental protection. Lessees...

Environmental Compliance Monitoring Program for Offshore Oil and Gas Exploration and Development and Production Activities in the Pacific OCS Region
The Pacific Outer Continental Shelf Region of Minerals Management Service has recently development and is implementing an Environmental Compliance Monitoring Program. Each of the 24 oil...

The Permitting Process for Oil Exploration and Development Projects on the North Slope of Alaska?An Oil Company Perspective
The five oil fields of Alaska's North Slope, including the giant Prudhoe Bay field the largest oil field in North America, contribute approximately 25% of United State domestic oil production...

Resource Extraction Activities in the Coastal Zone?The Impact of Offshore Oil Production on Coastal Communities
There are few studies that examine the impact of offshore oil extraction on social problems, educational attainment and economic health of communities. The results of this study demonstrate...
