Unconventional Subsea Technology Deployment Opportunities for Long Tieback Applications

This presentation provides an assessment of CAPEX savings opportunities when deploying unconventional technologies for long distance tiebacks. The assessment includes two different tieback scenarios (200km and 400km) where the reference case is conventional electro-hydraulic architecture, and comparing it to the following alternatives: (a) electro-hydraulic controls with hydraulic-only umbilical + DC/FO; (b) All-Electric Subsea (AES) + 3kVDC power transmission; (c) All-Electric Subsea + DC/FO.
