This presentation explores how an all-electric subsea control concept spanning from the topside to the well, will help making CCS projects more affordable by replacing traditional hydraulic systems with solutions that offer equal safety and operation liability with less CO2 footprint and faster installation time. The proposed concept introduces innovative technologies for offloading systems, x-mas trees, actuators, subsea control system and flexible pipes.
To accelerate and scale up Carbon Storage projects, disruptive innovations are crucial to simplifying system solutions, lowering total cost of ownership, all whilst ensuring highest safety and environmental protection standards. The presentation details collaborative efforts among a group of suppliers to streamline subsea CO2 Injection using lean all-electric technology integrated in a seamless way.
Key innovations for the subsea infrastructure include self-orientation tubing hangers, light-weight x-mas trees and actuators requiring minimum power and space. The low power requirement enables the feature of integrating power cables into the flexible pipe cross section eliminating the need for an external dynamic umbilical.
For the topside part, the concept utilizes offshore CO2 transfer systems, catering to CCS project demands for continuous and large quantity CO2 injection in all weather conditions. This eliminates the necessity for long and expensive trunklines, optimizing scalability opportunities for CCS projects.
The introduced innovations aim to improve installation time, first injection date and significantly reduce Total cost of ownership (CAPEX and OPEX).
