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