Marine Pipeline and Riser design, whether of a preliminary or detailed nature, usually involves the following elements with the degree of detail depending on the project stage and level of information 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
• Riser Vortex Induced Vibration studies
• Riser analyses
• Risk analysis studies
• Leak detection system selection, and remedial measure
• Riser analyses, whether for traditional platform risers, J-tubes, steel catenary risers, top tensioned and hybrid risers and other designs as appropriate
• 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
• Design reports

INTEC also offers specialized engineering capabilities, such as for extreme environment design (e.g. Arctic conditions) or Installation Engineering (e.g. pipelay systems).
