Atteris provided an experienced pipelines team equipped with in house developed automated engineering processes to propose refine and select route corridor options for survey for the various potential tie-backs. Route corridor selection included consideration of multiple issues, including geohazards, seabed roughness, and current and future field layouts. Given the challenging nature of the seabed in much of the development area a detailed route scoring algorithm was utilised to allow efficient assessment of route corridors, and to present the information in a simple and informative manner. Following the survey, the collected data was assessed, confirming the surveyed areas as suitable and adequate for future FEED, and preliminary routes were defined for priority tie-back options.
