Flowline projects are using more subsea technology for field development. Mature oil regions (Gulf of Mexico, North Sea) use subsea technology to tie in satellite fields. For arctic projects, subsea technology to enable tiebacks to the beach (distances of +200 km [124 mi]) is seen as the panacea for project ills. Currently, dual flowlines are the norm for subsea production delivery; the rationale is operational flexibility and improved reliability. This method can be costly over long distances, exceeding 30% of a project's capex. Therefore, project economics driven by flowline costs generate the need for a single-flowline solution. Are we there yet? Some innovations have undergone field trials; others have been adopted in platform systems. The performance history of these over time can significantly boost confidence in the single flowline for future subsea developments.
