MacGregor unveils bow-loading system for direct LCO2 offshore injection

The new Bow Transfer System (BTS) leverages 50 years of experience with MacGregor's existing bow-loading architecture, with approximately 79% of the components utilizing field-tested technology. Engineers modified the design to handle the specific physical properties of liquid carbon dioxide, including extreme temperature sensitivity. Seal materials underwent rigorous testing with the research organization SINTEF to ensure structural integrity during rapid gas decompression and at temperatures as low as -57°C. The system is built to maintain a stable connection in heavy sea states, enduring waves of five to six metres and sealing against water ingress at depths of up to 150 metres.

Øyvind Solli, Development Programs Manager at MacGregor, noted that the system supports four distinct architectures, ranging from 30 to 300 bar, providing operators with options for both seabed swivels and disconnectable turrets. The company has already completed the initial planning phase of a technology qualification process with DNV, which included comprehensive threat and risk assessments. Prototype testing and full demonstration are scheduled for mid-2027, with the company showcasing the technology this week at the ONS 2026 conference in Stavanger.
