OGCI, Stena, GCMD get ABS’ nod to use CO2 capture onboard oil tanker

A consortium of global shipping organisations and the Oil and Gas Climate Initiative (OGCI) have received approval in principle (AiP) from the American Bureau of Shipping (ABS), the US ship certification agency, to use a carbon capture system onboard an oil tanker.

The seven-member consortium includes the Global Centre for Maritime Decarbonisation (GCMD) in Singapore, OGCI, ABS, Stena Bulk, Alfa Laval, the Netherlands Organization for Applied Scientific Research (TNO) and Deltamarin, which provides ship services for marine and offshore industries.

The two-year, three-phase demonstration project is investigating onboard capture and storage and offloading captured carbon dioxide to address the operational challenges and opportunities of deploying carbon capture technology on ships.

Moreover, the project aims to demonstrate the feasibility of using carbon capture onboard a vessel and is one of the largest of its kind, according to the partners. Approval in principle allows the consortium to consider whether the project will move to the next stage, which includes engineering, procurement and construction.

Following a full engineering study, the carbon capture system will be built and tested prior to integration onboard a Stena Bulk medium range (MR) tanker for sea trials. A rigorous stage gate review process will be conducted prior to the progression between stages.

The members believe the onboard carbon capture system could help accelerate commercial deployment of shipboard carbon capture technology within the next five years.

“The ABS’s approval in principle is a significant step forward for an important initiative to reduce emissions from shipping and demonstrates the value of collaborating across industries to develop decarbonisation solutions. As we move towards deployment, OGCI will continue to provide expertise on carbon capture to help our partners show the potential of the technology to meet ambitious decarbonisation goals set by the maritime industry,” Michael Traver , head of OGCI’s Transport workstream, said.

“Our support goes beyond providing technological and engineering expertise in this field; we will provide access to the Alfa Laval Test & Training Centre to test the carbon capture installation and impart training to the crew before its deployment on a vessel. Decarbonisation demands the development of a wide range of emission-reducing technologies and we want to facilitate their development by collaborating with the maritime industry and helping reduce vessels’ carbon footprint,” Sameer Kalra , President of the Marine Division at Alfa Laval, stated.

“It is fantastic be able to receive this AIP from ABS and move forward towards installing a CCUS system on one of our Medium Range tankers. Advancing carbon capture is one of the central ways that shipping will be able to meet its decarbonisation goals… Installing a CCUS system on one of our vessels demonstrates our long-term commitment to technological innovation and sustainability. We intend to use the system beyond the scope of this pilot project, proving to the market what is already possible through collaboration,” Erik Hånell , CEO of Stena Bulk, noted.

“This is a milestone for onboard carbon capture technology, with significant potential to accelerate the pace of commercial applications. Carbon Capture will have a critical role to play in the decarbonisation of shipping and we look forward to continuing our support, sharing our extensive technical guidance as we enter the prototype phase of this important project,” Panos Koutsourakis , ABS Vice President, Global Sustainability, added.

The global shipping industry is looking at a range of solutions, including low-carbon fuels and onboard carbon capture, to help achieve a target to halve its greenhouse gas emissions by 2050 from a baseline of 2008.

The consortium began the first phase of Project REMARCCABLE (Realising Maritime Carbon Capture to demonstrate the Ability to Lower Emissions) in 2022, which involved conceptual design and a front-end engineering design study of the carbon capture system.

In December last year, the GCMD also issued an invitation-for-proposal (IFP) to evaluate the safety, technical and operational requirements for offloading shipboard-captured CO2 during port calls.

The second phase would include engineering, procurement, and construction of a prototype shipboard carbon capture system and onshore commissioning. Phase three focuses on integrating the carbon capture system with the MR tanker and conducting sea trials.

The GCMD plans to launch a study on offloading the liquid carbon dioxide (CO2) to resolve potential challenges and inform the third phase of the project.
