TAP-630-Risk Assessment for Pipelines in Deepwater (RAPID) JIP

The objective of this study was to evaluate and extend pipeline risk assessment methodology for deepwater pipelines in areas of uneven seabeds. Study objective included:

Task 1: Evaluation of Data Quality Objectives for Furrow Regions

Task 2: Development of Approximate Method for Analyzing Pipeline Risk in Furrow Regions.

One of the main objectives of the original JIP proposal was enhancement of the hydrodynamic and bed scour models used in the pipeline risk assessment methodology. A primary focus of the model enhancement was improved prediction of bed scour in the vicinity of the pipeline along the shoulder of the furrow. An alternative approach to improving prediction of bed scour in this region is applying the results of previous studies on bed scour around structures to a pipeline in a furrow field.
