JIP Developing Model To Simulate Arctic Sea Spray Icing
DNV GL’s Rig Spray JIP aims to help operators working in the Arctic better predict the potential for sea spray icing on offshore structures, which poses a significant safety hazard.
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.
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.
