Design of Prefabricated Offshore Structures for Ice Forces
The design of fixed offshore structures to resist forces from sea ice features is reviewed. The emphasis is on prefabricated structures constructed elsewhere, towed to location and installed,...
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...
Design of Offshore Pipelines for Ice Environments
Design and installation of offshore pipelines in cold regions requires special care. Low ambient temperatures may cause increased friction losses in oil and gas lines due to wax crystallization...
Design of Navigational Structures for Ice Forces
An overview of ice conditions and the types of ice action that are hazardous to navigational structures is presented. Depending on the circumstances, ice failure against structures occurs...
Pile Construction Practices in Arctic Regions: State-of-the-Art
Pile installation techniques in cold regions include drill and slurry, and driven methods for foundation designs. In the past, piles used for structural support in permafrost have consisted...
Cold Regions Safety
Presented here are some essential basics for the development of a comprehensive cold regions safety program. The intent is to cover a few topics in some detail, and to increase the general...
Oil Rigs Designed to Combat Arctic Ice
Exploration and drilling rigs now being designed for use in the Beaufort Sea must withstand ice forces never before encountered. Design approaches include using the geometry of these structures...
Landmark Projects of Yesterday, Today, and Tomorrow
Excerpts are discussed from major papers to be presented at the March 1982 Construction Equipment and Techniques for the Eighties Specialty Conference to be held at Purdue University....
Grouting in Geotechnical Engineering
The 63 pages included in these proceedings came from 12 different countries and deal with the pertinent advances in grouting materials and technology that have occurred throughout the...
Construction Equipment & Techniques for the Eighties
Thirty-three papers on construction equipment and techniques are presented. Construction equipment management is discussed, including criteria for equipment selection, utilization and...
Causes and Preventions of Lamellar Tearing: Engineer's Notebook
Within the past 10 years, a steel cracking problem, lamellar tearing, has arisen after welding of thicker sections and higher-strength steels. A separation underlying a weld joining plate...

Directional Wave Spectra Applications
These collected papers and their ensuing discussions presented at the September, 1981 symposium at the University of California on directional wave spectra applications examine the present...
Dynamic Response of Pile Foundations
Analytical Aspects
Recent developments in the analytical solutions and relevant measurements regarding pile foundations are examined. Pile foundations for both onshore and offshore structures are covered,...
Cognac: World's Tallest Offshore Oil Platform
Shell Oil's 1980 OCEA-winner is a three-sectioned design of steel fabrication and deep-sea installation. Cognac is currently the world's tallest, heaviest, and...
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...
New York: Water City
New York's waterfront (some 584 miles) is its most impressive natural resource and its biggest management headache. In Manhattan, changes in waterfront technology (container...
California Soon to Have Platform in 850 Ft of Water
Exxon's oil drilling and production platform, to be placed off Santa Barbara, Calif. next July, will stand in water twice as deep�� 850 ft versus about 420 ft�� as any other...
Paul Bunyan Among Offshore Steel Structures
The world's two largest drydocks, the larger 1,150 x 800 ft in plan were used to assemble on land the four steel jackets. They now stand in the North Sea in about 400-ft of...
New Jack-Up Drill Rig Extends Their Range Into 375-Ft Water Depth
A new design of jack-up drill now building for the Gulf of Mexico extends from 250 ft to 375 ft, the depth of water in which they operate. Until now what limited their depth was their...
