Statoil and Rutter Complete R&D for Improved Remote Ice Detection and Tracking
Rutter, Statoil Canada, and the Government of Newfoundland and Labrador completed a collaborative research and development (R&D) project aimed at improving offshore oil and gas operations in harsh environments with ice conditions.
Concept for Ice-Resistant Offshore Terminal for Arctic LNG Export
Cost and delivery of long-distance natural gas pipelines to a distant liquefaction facility at a warm-water port has become excessive, and environmental restraints have been increasing. An alternative is an offshore ice-resistant LNG port accommodating a new class of LNG transport vessels.
Design Tools for Arctic Subsea Pipelines
As the design methodologies evolve for arctic pipelines, strudel scour, permafrost thaw settlement, and ice gouging need to be factored in with environmental and geotechnical data, limit states, and trenching and backfilling activities.
Arctic Pipeline Route Selection
To reduce the risks to arctic pipelines from natural or geologic hazards, a more sophisticated approach to routing compared to traditional methods based on only the shortest length of pipe or connectivity to existing infrastructure is needed.
Taking on the Arctic With New Concepts
New approaches to arctic activities include a concept for an offshore ice-resistant LNG export terminal, the design of subsea pipelines, and the optimal routing for the pipelines to mitigate the unique risks in arctic regions such as ice-gouging and permafrost thaw.
Gas Begins To Flow in Russia’s Third Arctic Pipeline
Gazprom’s third pipeline to course through the Arctic further decreases Russia’s dependence on using Eastern European countries as thoroughfares to export its gas to markets in Western Europe.
System-Reliability Analysis by Use of Gaussian Fuzzy Fault Tree: Application in Arctic Oil and Gas Facilities
Reliability analysis helps identify bottlenecks, assess risk, improve availability, and optimize maintenance. The challenge in Arctic regions is the lack of data -- normal climate analogs may not apply.
Optimization of Integrated Template Structures for Arctic Subsea-Production Systems
This paper analyzes the various selection methods of integrated template structures (ITSs) for use in the Arctic environment. Operation and installation of subsea modules in the Barents Sea are also analyzed in this paper.
Trenching of Pipelines for Protection in Ice Environments
This paper highlights the issues and challenges surrounding pipeline trenching and burial in ice-gouge environments. The current state of practice is discussed along with the technology gaps that need to be addressed.
