The Revolution of Methanol Propulsion in the COSCO LIBRA: A Historic Milestone in Maritime Decarbonization
In a groundbreaking move towards decarbonizing maritime transport, Everllence, in collaboration with COSCO Shipping Lines, has successfully completed the world’s first conversion of a two-stroke Everllence B&W S90 engine to operate on methanol. This feat was tested on the COSCO LIBRA container ship, which boasts over 20,000 TEU, marking a significant step forward in the use of alternative fuels. The vessel’s original 11S90ME-C engine has been transformed into an 11S90ME-LGIM (Liquid Gas Injection Methanol), showcasing the viability of methanol as a large-scale fuel solution for the maritime industry. This development signifies the companies’ commitment to using sustainable technology and reducing carbon footprint. Sea trials not only confirmed the technical capability of the system but also paved the way for future adaptations of similar engines in vessels worldwide, setting a precedent in the maritime sector’s energy transition.
The Technical Alliance Behind the Achievement
The success of the project lies in the close collaboration between Everllence PrimeServ, Everllence’s after-sales division, and COSCO Shipping Heavy Industry (CHI). Together, these entities carried out the engineering, design, project management, installation, commissioning, and final sea trials, ensuring that every aspect of the project met the highest standards of quality and efficiency. To ensure the technical readiness of this unique conversion, Everllence opted for a 4S90 test engine in Japan in early 2025. This test bench was crucial in validating the performance of the S90 engine with methanol in real operating conditions, accelerating its implementation in commercial vessels. The partnership between Everllence and CHI is a testament to how collaboration among industry leaders can achieve significant advances in sustainable technology, highlighting the importance of working together to address global challenges such as decarbonization.
Decarbonization: Challenges and Opportunities
Michael Petersen, Senior Vice President and Head of Everllence PrimeServ, emphasized the strategic relevance of this collaboration and its broader impact on the maritime industry. This milestone not only reinforces COSCO Shipping Lines’ role as a pioneer in sustainable technologies but also presents a practical path to reducing emissions in the global fleet. Everllence has demonstrated its ability to carry out large-scale alternative fuel projects. With 26 dual-fuel conversions completed and a growing portfolio of projects in various alternative fuels, the company is well positioned to lead the energy transition in the maritime sector. This collaboration not only shows that large-scale conversions are technically viable but also commercially viable, paving a practical path towards a faster energy transition in the global maritime industry.
Methanol as the Fuel of the Future
Methanol is increasingly seen as one of the most promising alternative fuels for maritime decarbonization due to its multiple advantages. One of its greatest strengths is its compatibility with existing infrastructures, allowing for handling with bunkering systems with minimal adaptations. Additionally, methanol is already produced on a large scale, and green methanol projects are gaining momentum worldwide. Its use aligns with the International Maritime Organization’s (IMO) decarbonization goals for 2030 and 2050, providing an immediate and viable solution to meet environmental regulations. The use of methanol in large-caliber two-stroke engines sets a new precedent in the scalability of decarbonization, showing that current initiatives can lead to achieving global carbon reduction goals without the need to wait for entirely new solutions.
Impact on the Maritime Industry and Job Opportunities
The conversion of the COSCO LIBRA presents significant opportunities for the maritime industry, especially in terms of employability and professional development. With over 300 vessels worldwide equipped with S90 class engines, there is a vast potential market for similar adaptations, which can generate considerable demand for specialized professionals in alternative fuel technology. These initiatives not only promote sustainable practices but also foster technological innovation and create new job opportunities for engineers, technicians, and project managers in the maritime sector. We invite interested individuals to submit their resumes to the participating companies, as the future of maritime transport depends on adapting to these new technologies. As the maritime industry moves towards a greener future, the focus on training and professional development in alternative fuel technologies will be crucial to ensuring a successful and sustainable transition.
Conclusion: A Sustainable Future in Sight
The conversion project of the COSCO LIBRA exemplifies how the synergy between technological innovation and a strong commitment to sustainability can pave the way for a net-zero future in maritime transport. Everllence and COSCO have shown that collaboration and ingenuity can overcome seemingly insurmountable challenges, inspiring other industry players to follow their lead. With increasing pressure to meet emission reduction targets set by the IMO, initiatives like this are more important than ever. They not only represent a significant technological advancement but also a call to action for the entire maritime industry to unite in the fight against climate change. The transition to cleaner and more sustainable fuels in the maritime sector is a complex process that requires the involvement of all stakeholders. By moving forward together, we can ensure that maritime transport remains a key driver of the global economy while safeguarding the planet for future generations.
