Structural Solutions for the Enhancement of Gravity Foundations on Very Soft Arctic Soils
Very soft soils in several offshore Arctic areas cause a major concern in the design of gravity foundations, particularly in view of the high magnitudes of ice loads. Preliminary studies...
Stochastic Finite Element Analysis of Gravity Platform Foundation
Gravity foundation design requires determination of total and differential settlement, vertical stress distribution beneath the raft and maximum shear stresses in the sand layers in the...
Thaw Settlement as a Result of Permafrost Deterioration
An overview is given of floor and footing failure as a result of deterioration of permafrost. Consideration of causes for the deterioration and methods of repair are addressed in general...
Developing a Drilling Structure for Arctic Waters
Fluor-Doris of Houston has developed a mobile, composite concrete and steel drilling structure called the Arctic Composite Platform (ARCOP). This platform is capable of operations in water...
Arctic Drilling and Production Platform Concept
An 80-well Arctic drilling and production platform for water depths to 100 feet in the Beaufort Sea transition ice zone is presented. It includes a novel inner caisson to help resist large...
A Beaufort Sea Deepwater Production Structure
There will be a need for large crude oil production platforms in Beaufort Sea water depths between 20 and 50 m and at locations with soft seabed soils and far from readily exploitable...
Concrete Space Frame Applied to an Arctic M.O.D.U.
The BOUYGUES experience in the use of concrete space frame technology for civil works and the application of this technique, combined with high strength concrete and prefabrication, to...
A Hybrid Structural Ice Defense Mechanism
A hybrid plate composed of steel outer surfaces and a concrete core has characteristics that make it desirable for use on offshore structures in ice prone environments. The service and...
Jumbo Modules for Artificial Islands
The development of the Arctic Offshore oil fields has led to the consideration of gravel islands or other structures to support oil production facilities. The island and the assembly site...
Geotechnical Design of Caisson Islands
There are a number of areas where fundamental geotechnical research is required so that non-conservative, rational and safe design of artificial exploration islands can be achieved. Some...
Arctic Offshore Engineering: A New Graduate Course at Texas A&M University
Based upon the present projections for the offshore petroleum industry, many of our future engineering graduates will find employment related to Arctic Offshore activities. In an effort...
Cost-Effective Arctic Concrete Structures
The economic development of offshore Arctic petroleum fields dictates that Arctic structures be both cost-effective and deliverable with minimum lead time. Concrete structures are typically...
Coastal Erosion's Impact on California Offshore Oil Development
Recent oil discoveries in the offshore Santa Maria Basin and the Santa Barbara Channel will require the construction of new oil facilities located along 90 miles of Santa Barbara County...
Local Pressure in Ice-Structure Interactions
Two models for the determination of local pressures during marine ice or iceberg collisions with bottom-founded structures are presented. The first model is a two-dimensional analytical...
New Ways with Concrete
When NASA builds on the moon and in space, the structures will be concrete, say researchers at the Portland Cement Association's Construction Technology Laboratories. They...
Regulatory Reform in Alaska: An Oil Industry Perspective
The State of Alaska recently implemented regulatory reform procedures to streamline the permitting process and ease the regulatory burden on the regulated community, as well as the burden...
Constraints on the Use of Development Management to Reduce Coastal Storm Hazards
This paper has presented some important information about perceived constraints to the enactment and effective implementation of development management measures to reduce coastal storm...
The Bowhead Whale and Offshore Petroleum Operations in the Arctic
Eskimos, environmentalist groups, and government agencies have stated their concerns about possible effects on the bowhead from offshore petroleum operations. These concerns fall into...
Dune Construction on Perdido Key, Alabama
In recent years, the Alabama coast has experienced significant pressures for development. To make development compatible with beach preservation, the Alabama Department of Environmental...
Man-Made Offshore Islands: An Innovative Solution to Coastal Erosion
Existing shore-parallel detached breakwaters have resulted in the accretion of sand along the shoreline in the wave shadow of the structure. Significant prograding of the beach has replaced...
