ABS has granted an Approval in Principle (AiP) to Overseas Shipholding Group Inc (OSG), the parent company of Aptamus Carbon Solutions, for the initial design of a liquefied carbon dioxide (LCO2) barge. This barge design is a key component of the Tampa Regional Intermodal Carbon Hub (TRICH) project, aimed at capturing, storing, and processing emissions from Florida industries to transport them to nearby sequestration sites.
The articulated tug and barge unit (ATB) represents a pioneering effort in the U.S. for carbon capture projects. The cargo handling equipment design incorporates medium-pressure LCO2 Type-C tanks, enabling it to carry up to 20,000 metric tons of cargo. The maximum operational pressure was determined based on historical data and market trends, taking into account loading capacity and time savings.
ABS conducted design reviews in line with classification requirements, particularly adhering to the latest ABS standards for constructing and classifying liquefied gas tank barges. The safe transport of CO2 is crucial within the carbon value chain, and ABS is honored to leverage its expertise as the world's leading classification society for gas carriers to support this significant project in the U.S. operations,” stated Gareth Burton, ABS Senior Vice President of Global Engineering.
“This AiP marks another significant milestone in Aptamus's journey to lead the advancement of CO2 storage and marine transport in the United States,” said Jeffrey Ross Williams, President of Aptamus. “This ABS AiP is another crucial step in our mission to steer the U.S. maritime industry toward developing the technology necessary for success in our national emission reduction goals while exploring new and expanding business opportunities in the global energy transition,” Williams added.
Kent Merrill, Vice President of Marine Projects at Aptamus, noted, “We are proud to have designed the first LCO2 vessel specifically for operation in the coastal waters of the U.S.” Articulated tugs and barges (ATBs) are well-regarded and effective for transporting petroleum products in the U.S. for various reasons, and these advantages also apply to LCO2 vessels. We anticipate the continued innovative development of the design, including engineering the tug to utilize green methanol or other sustainable fuels and technologies. We extend our gratitude to ABS for their valuable partnership in this endeavor, along with other engineering contributors like Corban Energy Group and Herbert Engineering Corporation.
