NOV advances subsea storage technology through Deepstar grant

NOV partners to study subsea chemical storage systems that can unlock more from brownfield lifecycles and all-electric long tiebacks.

Oct 20, 2023

NOV has received a grant from DeepStar® to execute a study to further develop and demonstrate its subsea chemical storage technology. The study will focus on business cases for the proposed subsea chemical storage and injection (SCSI) system in two applications – brownfield life extension and all-electric greenfield application. The study will analyze CAPEX and OPEX for the system compared to existing solutions. Goals include finalizing the study by end of 2023 and technical feasibility for the SCSI system for the given scenarios.

Receiving the grant from DeepStar underscores the immense potential of NOV's subsea storage solutions. This project will showcase our technology's versatility for chemical storage and injection, field life extension, and enabling longer subsea tiebacks – helping operators overcome topside constraints and move towards all-electric solutions.

"We are excited to grant NOV this study to explore the business case for subsea chemical storage," says DeepStar's Project Champion. "This provides a tremendous opportunity to evaluate how NOV's innovative storage technology can potentially extend the life of brownfield developments and unlock new value for DeepStar members' energy assets. By enabling larger-volume storage closer to offshore operations, this solution has the potential to create major efficiencies while opening up new possibilities for our customers' portfolios."

The study advances the technology being developed from our ongoing Joint Industry Project (JIP) with Equinor, ABS, NZTC and The Research Council of Norway. The JIP project, awarded in 2021, will enable larger volume storage capabilities for all relevant fluid types in a subsea environment. The project is on track for completion in 2023 and includes submerging and testing two 200 cubic meter Subsea Storage Units (SSUs), as well as material compatibility and service life assessments.

NOV continues to build on its 160-year history of pioneering solutions to empower the global energy industry, making oil and gas operations more efficient and environmentally sustainable both today and into the energy transition.
