Overview of Artificial Island Design and Construction in the Arctic
An overview is provided of the design and construction of artificial islands in the Arctic. Since the early seventies more than 20 islands have been constructed in the Alaskan and Canadian...
Arctic Island Construction
The history of island building in the Beaufort Sea of Canada and the United States is reviewed. Construction methods are discussed. These include hauling material from onshore in both...
Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
The Estimation of Ice Loads From Caisson Deformations Gulf Canada Molikpaq
The Gulf Canada Resources Mobile Arctic Caisson 'Molikpaq' is a bottom founded steel exploration platform capable of year-round operation in the Beaufort Sea....
Dynamic Global Forces on an Offshore Structure from Multi-Year Ice Floe Impacts
Estimation of global ice forces from ice floe impact against artificial islands and offshore platforms is essential for platform design. The discrete element program, CICE, has been validated...
Logistics for Structures Sealifted to the Arctic
Sohio has successfully pioneered the development of the Prudhoe Bay reservoir by sealifting prebuilt oil processing facilities from the lower 48 states. The experience thus gained is being...
Oilspill Response Technology for the Arctic
Alaska Clean Seas is a spill response organization whose area of interest includes all of the marine environment surrounding Alaska. It provides support to members in contingency planning,...
Spatial Analysis of Ice Charts
Spatial approaches to ice environment modeling can not only lead to better local hazard predictions but also produce regionalizations that are useful for construction, navigation, and...
Utilizing Design Events Within Risk-Based Design
Design load selection based on the return period of an environmental event is not possible when the event is described by more than one parameter. Risk analysis can be used to associate...
Risk Assessment of Sea Bottom Scouring Using Fuzzy Set Theory
An approach to the assessment of risk to buried pipelines from ice gouging is developed using Fuzzy Set Theory. Statistical procedures currently used to analyze ice gouge data are inadequate...
SHADS: Mobile Arctic Drilling Platform
To minimize costs of Beaufort Sea exploration programs, the industry needed a mobile arctic drilling structure that requires little or no site preparation, does not require an active ice...
Endochronic Constitutive Modeling of Frozen Soil
The static behavior of a permafrost type foundation, for a typical artificial island in the Arctic, is determined using endochronic axisymmetric finite element analysis. Endochronic constants...
Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...
Three-Dimensional Analysis of an Artificial Island
A nonlinear, finite element analysis has been carried out to investigate the influence of three-dimensional loading and geometry on deformation and failure of an artificial island. The...
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...
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...
Pipeline Hardware: Special Designs for Arctic Projects
The hardware used to support and protect arctic pipelines has evolved through several years of innovative design work by various engineering firms. The hardware used on the Kuparuk River...
