At times, infield and export subsea pipeline routes are manually designed and sited in the early stages of a project using only existing, publicly available, low-resolution bathymetric data with minimal consideration for the geological complexity that may affect the proposed infrastructure. Geohazards across the development area may not be identified or could be misinterpreted based on the resolution of the available data. Selecting a pipeline route before a detailed geohazard assessment is completed may result in revisions to the route, taking up valuable time and resources, and leading to significant costs.
This paper describes the workflow of an example pipeline route optimization performed on multiple datasets with varying resolutions across the same study area. Each dataset was individually analyzed and assessed for regional geohazards, then least-cost pipeline routing methods were used for pipeline route selection. We show how least-cost route optimization is affected by data resolution, geohazard identification, and geocost weighted inputs and emphasize the importance of incorporating the highest resolution data available when conducting pipeline route optimization.
