Offshore carbon capture and subsea injection system gets approval

Classification society American Bureau of Shipping (ABS) has given an approval in principle (AiP) to a large-scale, carbon dioxide (CO2) injection system developed by Hyundai Heavy Industries Group (HHI Group).

Carbon capture technology has been gaining attention lately as several oil and shipping companies are looking to rein in their CO2 emissions towards upcoming regional and global reduction targets.

ABS head Christopher Wiernicki believes that net zero CO2 cannot realistically be achieved without efficient carbon capture and storage (CSS) technology.

HHI Group has developed a CSS system that will be installed on an offshore floating platform, where it will capture CO2 from visiting gas carrier vessels.

Having a place to safely store the CO2 at in large volumes is then key to the CCS process.

The captured CO2 will then be compressed under high pressure before being injected beneath the ocean floor for geological carbon storage. The system is equipped with a CO2 heating circuit for compression. It will have an injection capacity of up to 1 million mt/year.

HHI Group, which is made up of Hyundai Heavy Industries (HHI) and Korea Shipbuilding & Offshore Engineering (KSOE), has developed the platform in partnership with Korea National Oil Corp.

Both HHI Group and ABS are currently focussing on “the potential to grow the offshore CCS business to support future shipbuilding and the marine industry,” KSOE’s senior executive vice president and chief technology officer Sungjoon Kim said.
