Arctic Earth Materials for Offshore Construction in Alaska
With the exploration activities onshore and offshore and the development of production facilities, the need for granular earth materials on the North Slope of Alaska is ever present. The...
Constructibility of Arctic Offshore Structures
The costs of structures designed for Arctic Offshore Drilling and Production Platforms have reached extreme levels. A major component of the costs of such structures is their constructibility....
Offshore Seawater Intake in the Arctic
Waterflood has become a proven technique for enhancing oil recovery from oil producing reservoirs. At Arctic north slope areas, seawater has been used successfully for such operations....
Ice as a Construction Material in the Offshore Arctic
Ice is the most available and abundant material in the offshore Arctic, and it is therefore one of the most cost-effective construction materials. Over the past decade, ice has been used...
Fatigue Damage for Reinforced Concrete Offshore Structures
When concrete structures are subjected to fatigue loading - resulting from ice or wave loads - progressive damage occurs with increasing number of cycles. Nonlinear damage evolution equation...
Microsilica Concrete: Properties and Applications
With the advent of microsilica concrete, a new generation of high to ultra high strength and high durability concretes have become commercially feasible and are now being specified and...
Asphalt Revetments for Slope Protection in the Arctic
Experience in the Netherlands demonstrates that slope protection of coastal embankments subjected to heavy wave action can be accomplished with lining systems made of mixtures of asphalt...
Soil-Pipeline Interaction During Ground Movement
The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement....
Technical Considerations for Beaufort Sea Pipelines
The development of Beaufort Sea fields requires construction methods and equipment for pipeline installation and trenching providing a balance between safety, reliability, and economy....
Directional Drilling to Install Arctic Marine Pipelines
Directional drilling for offshore Arctic pipeline construction offers essentially year-round construction performance capability. The most readily acknowledged alternate candidate construction...
Pipeline Landfall Construction by Horizontal Drilling
The segment of an offshore pipeline where the transition is made from standard offshore laying procedures to standard on land laying procedures represents a difficult and costly construction...
An HF CODAR Doppler Transponder System
Gulf Oil Exploration and Production Company completed two major phases in the development of a high frequency (HF) CODAR Doppler transponder system for measuring sea ice motion. The system...
North Sea Technology Transfer to the Bering Sea
Concrete platforms in the North Sea are reviewed, including technological considerations and economic factors involved in their selection and application. The applicability of this technology...
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...
Pile Creep Designs for Frozen Layered Profiles
A concept of relative creep stiffness suitable for the evaluation of the long-term, uniform creep behavior of non-ice type, frozen soils is presented. This concept extends the current...
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...
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...
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...
