Major Issues Associated with Offshore Petroleum Development
Santa Barbara County has been confronted with a host of significant issues related to offshore oil and gas development, including: the extent and limitations of local control over development;...
Joint Review Panels ? A Cooperative Approach
The Joint Review Panel (JRP) developed out of a need to address the interests of various agencies on a local, state and federal level which have permit jurisdiction over offshore oil and...
Mitigation of Impacts Associated with Oil and Gas Development Projects
The large scale oil and gas development occurring in Santa Barbara County has the potential to cause extensive environmental impacts on many resources within the county. The county has...
Innovative Approaches to Mitigating Cumulative Impacts
Faced with rapid acceleration in offshore oil and gas development, Santa Barbara County has advanced the recognition, evaluation, and mitigation of cumulative impacts. The County's...
Offshore Oil and Gas NPDES Permits: Creative Solutions?Three Case Studies
The U. S. EPA has responsibility under the Clean Water Act (CWA) to maintain and enhance the quality of the Nation's waters. Section 402 of the CWA authorizes EPA to issue...
Coastal Area Development and Offshore Man-Made Islands
With offshore man-made islands, it is necessary to make the aims of land use clear in terms of the various conditions, such as a severe environment and vast construction costs. As technological...
Emergency Shore Protection
Emergency shore protection usually requires design and construction to be completed in a 2 to 3 week period. Emergency shore protection measures at Surfside and Ventura, California required...
Bulkhead Instability in Soft Soil
This paper presents a case study involving the severe disturbance of the subsurface soils in front of an existing bulkhead caused by the berthing of a jack-up type, offshore drilling vessel....
The Chicago Lakefront Plan - 1986
Although Chicago is considered to have one of the world's most beautiful and also stable waterfronts, much of its shore protection is in imminent danger of failure. Nearly...
Local Buckling and Cyclic Behavior of Tubular Members
The effect of the local buckling is included in the cyclic analysis of tubular members. The cyclic moment-curvature curves are obtained numerically. Three types of closed form expressions...
Simulation Algorithms for Offshore Structures
A rational procedure for characterization of water depths for a random sea state is developed, in context with linearized wave theory. The importance of using the expressions for 'intermediate...
Design of Drilled Piers Subjected to High Overturning Moments
The results are presented of a research study directed at improving the state-of-practice, and resulting foundation economy, in the design of laterally loaded drilled pier foundations...
Artificial Ice Islands for Deep Water and Production Structures
The need for an island to survive the summer melt season is introduced. To account for surface melting and erosion from waves and currents during this season, the island's...
Drilling Unit Approval and Sea Ice, Alaska OCS
This paper describes types of ice conditions that have been, or could be, encountered while conducting Alaska Outer Continental Shelf (OCS) operations. The types of ice monitoring programs,...
Iceberg Impact Load on a Gravity Based Structure
The mechanics of the eccentric collision of an iceberg against a fixed, rigid, gravity based structure are discussed. A closed form solution is derived for the case of infinite friction...
Design and Monitoring of an Ice Drill Pad
An ice pad was sucessfully designed and built to provide a suitable foundation for an exploratory drill rig in the National Petroleum Reserve of Alaska in early 1985. Design considerations...
Design Evaluations in Support of Offshore Facilities and Gravel Islands in the Arctic
Development of oil resources in Northern Alaska has involved the design of nearshore and offshore facilities and structures in the Beaufort Sea and Prudhoe Bay in water depths ranging...
Design of Modular Structures for the Arctic
Sohio's efforts to continue the production and initial processing oil from Prudhoe Bay, Alaska requires additional production enhancement equipment on the Alaskan North Slope...
Repair Welding of Arctic Offshore Structures and Vessels
This paper describes the welding procedure development for repair or field modifications of offshore drilling structures and vessels made with several different steel grades produced for...
Wave Forces on an Arctic Monotower Platform
At offshore lease sites located along the western coast of Alaska, longer periods of open water can be expected. As a result, wave induced hydrodynamic loading will become a more significant...
