General Pipeline Design Engineering

Arctic pipeline design, whether of a preliminary or detailed nature, usually involves many areas of specific expertise discussed earlier, plus the following general pipeline design issues. The following elements with the degree of detail depending on the project stage and level of information are available at the time:

Design basis definition
Safety strategy recommendations
Pipeline hydraulics and sizing
Initial selection of pipeline route
Geohazard analysis
Stability analysis and determination of weight coating and/or trenching requirements
Determination of wall thickness and steel grade using traditional or limit-state design criteria
Pipe spanning analysis and determination of pipe support needs
Upheaval buckling analysis and assessment
Fatigue and fracture mechanic assessment
Vortex induced vibration studies
Risk analysis studies
Leak detection system selection
Shore crossing studies to determine the most cost effective method to install the pipeline in dynamic regions
Pipeline installation studies to verify that multiple installation options can be maintained for the sake of competitiveness
Cost analyses
Preparation of material specifications
Preparation of construction specifications
Preparation of route drawings
Permit application support
