Eskimos, environmentalist groups, and government agencies have stated their concerns about possible effects on the bowhead from offshore petroleum operations. These concerns fall into...
Splitting Common-Pool Offshore Oil & Gas Revenues
The Department of Interior (DOI) and several coastal states are currently at odds over an issue with enormous financial stakes as well as far-reaching implications in federal/state relations....
Permitting for Oil and Gas Activities in the OCS Mukluk Island?Beaufort Sea, Alaska 1983
In Alaska so little land is in private ownership that the primary means for the oil industry to obtain rights for exploration and development is through State or Federal petroleum lease...
Biological Stipulations and the Protection of Environmental Resources in the Gulf of Mexico
This paper documents the growing use of lease stipulations as an impact mitigation procedure in the Gulf of Mexico. In particular, the paper analyzes the role and effectiveness of biological...
Blind Drilling Down Under
Australia's largest blind drilled shaft is a 14 ft diameter fresh air shaft for the Agnew nickel mine 500 miles northeast of Perth. It was drilled in one pass using air-assisted...
Coastal Zone '85
Coastal Zone '85 was a multidisciplinary conference for professionals, interested citizens, and decision-makers to exchange information and views. Coastal zone management...
Evaluation of Non-Ductile Drilled-in Expansion Bolts
This paper provides background and justification for the design of closely spaced non-ductile drilled-in expansion bolts (bolts). It describes testing used to establish allowable design...
Role of a Standard in the Production of Drilled Shafts
The preparation of drawings and documents that describe the details of the installation of drilled shafts for a project requires an up-to-date standard. The role of the standard in the...
Geotechnical Perspective?Proposed Drilled Shaft Standard
In the writer's understanding, a standard is an agreed upon manual of practice and as such, sets the level of performance and attainment considered adequate. A standard is...
ASCE Drilled Shaft Standard: University Perspective
A critique is presented of the proposed ASCE standard on drilled shafts. Areas where major work is necessary relate primarily to the shaft design sections, establishment of loads, and...
Standards and the Contractor
The International Association of Drilled Shaft Contractors have written their own standards and have cooperated with other groups in similar activities. The author gives his ideas about...
Government Agency Perspective on Standard for Drilled Shafts
Relative to the proposed ASCE standard for Design and Construction of Drilled Shafts, the Tennessee Valley Authority (TVA) would be considered an 'owner'. However,...
Analysis and Design of Pile Foundations
Piles are one of the oldest type of foundation system known to man and as such have been previously studied in depth based on available modeling and monitoring techniques. An increased...
Oil Platform
The Cerveza offshore drilling platform demonstrates that a single-piece platform base for deep water is technically feasible and economically practical. The template-type fixed platform...
Artificial Islands
Artificial islands constructed from gravel fill have become a preferred approach to drilling for oil in hostile Arctic environments. These man-made islands are being built to serve as...
Design of Manmade Offshore Islands for Ice Forces
Approximately sixty percent of the undiscovered oil and fifty percent of the undiscovered gas probably lies in the sedimentary basins offshore Alaska (USGS 1980). Because of this hydrocarbon...
Drilled Piers and Caissons
Drilled piers, also called drilled caissons, drilled shafts, bored piles, and cast-in-situ piles, have recently undergone a period of growth in their use as foundation bearing elements,...
World's Tallest Offshore Platform Stands in 1025 Ft of Water
During the summer and fall of 1977 and 1978, Shell Oil installed the world's deepest drilling and production platform in water. Located in 1025-ft of water at the Cognac tract...
