Streamlined Multidisciplinary Work Flow Assesses Pipeline Slugging
An integrated multidisciplinary work flow can improve the assessment of pipeline slugging fatigue for offshore field developments.
Free spans exist in subsea multiphase pipelines laid over undulating seabed profiles or across continental scarps for offshore field developments. Slug-flow-induced fatigue damage on the free spans can have a significant effect on project economics. Slug-flow assessments can prove time-consuming. The complete paper describes an integrated iterative approach between the flow-assurance and pipeline-engineering disciplines to streamline the work flow based on the value or cost associated with changes in input parameters that affect pipeline fatigue-assessment outcomes.
Slug-Flow Assessment Work Flow
The complete paper further details key goals for each step.
Step 1: Plan Project Slug-Flow Design Requirements. Key to this step is to create a close interface between flow-assurance and pipeline engineers to discuss and align overall timing, critical decisions, and hold points that are required as part of the slug-flow assessment and any specific project-design considerations.
Step 2: Execute Slug-Flow-Prediction Assessment.
