Introduction

MacGregor, a leader in maritime technology, has introduced a groundbreaking Liquid Carbon Dioxide (LCO₂) Bow Transfer System (BTS) aimed at revolutionizing the transfer processes between ships and offshore facilities. Built upon five decades of successful bow-loading technology, this new system promises to streamline operations, eliminate the need for costly onshore infrastructures, and enhance safety during LCO₂ transfers.

The Need for Efficient LCO₂ Transfer

As industries increasingly prioritize sustainability and carbon capture efforts, reliable and efficient methods for transporting liquefied carbon dioxide become critical. Traditional methods often require expensive interim storage and conditioning facilities, which can hinder the efficiency of Carbon Capture and Storage (CCS) projects. MacGregor's innovative BTS addresses this issue by directly connecting capture facilities to offshore injection units, thereby reducing operational costs and enhancing logistical efficiencies.

Design and Technology Features

The BTS is engineered with 79% of its design based on MacGregor's tested Bow Loading System (BLS), which has been a trusted solution in the oil and gas industry since the 1970s. The remaining 21% features targeted modifications and new components that cater specifically to the unique and volatile properties of LCO₂. For example, the materials used in seals have been rigorously tested to withstand rapid gas decompression and maintain their integrity under challenging atmospheric conditions — achieving this at extreme temperatures as low as -57°C.

Moreover, the BTS is designed to accommodate adverse sea conditions with the capability to operate safely in wave heights reaching five to six meters. The system's advanced engineering ensures it can function effectively at underwater depths of up to 150 meters, sealing against potential water ingress effectively.

Supporting Sustainable Practices

According to Øyvind Solli, Development Programs Manager at MacGregor, this new Bow Transfer System is a breakthrough in ensuring seamless connections, transfers, and disconnections, regardless of the weather conditions. The system is aimed at supporting operators in maintaining uninterrupted service throughout the value chain of CCS projects, eliminating unnecessary delays that could adversely impact the environmental objectives of these initiatives.

Versatility and Flexibility

The design of MacGregor's equipment allows for a versatile approach to LCO₂ transfer. It provides operators with the flexibility to adapt the system to various operational requirements. The BTS is capable of supporting both low and medium-pressure scenarios (30–60 bar) as well as high-pressure direct reservoir injections (300 bar). This ensures that whether operators are utilizing seabed swivels or disconnectable turrets, their system can match specific field demands efficiently.

Commitment to Safety and Risk Management

In early 2025, MacGregor joined the EU-funded COREu research and innovation consortium, engaging in rigorous technology qualification processes alongside DNV, an international accredited registrar and classification society. MacGregor has successfully entered the qualification phase, which encompasses thorough assessments to identify risks associated with LCO₂ transfer equipment. DNV has recognized the findings, and a framework has been established for risk management and mitigation strategies to ensure utmost safety and operational efficiency in future implementations.

Upcoming Presentation

This revolutionary LCO₂ Bow Transfer System will be showcased at the ONS 2026 conference scheduled in Stavanger from August 24 to August 27. Attendees will find MacGregor at Hall 5, Stand 5540, offering insights and further information about this cutting-edge technology.

Conclusion

MacGregor continues to not only lead but transform the maritime and offshore operations landscape. Through its commitment to innovation and safety, the new LCO₂ Bow Transfer System symbolizes a significant step forward in supporting the industry’s environmental goals and advancing effective carbon capture technologies. The world can look forward to more efficient, sustainable solutions from MacGregor as they pave the way for future maritime operations driven by safety and environmental stewardship.
