Rio Tinto, a global leader in dry bulk shipping, has taken a significant step towards enhancing its vessel efficiency and reducing emissions by selecting Alfa Laval’s OceanGlide fluidic air lubrication system. This innovative move underscores Rio Tinto’s commitment to sustainable shipping practices while aiming for operational excellence.
Advancing Efficiency and Sustainability
In a bid to bolster vessel energy efficiency and contribute to the decarbonization of shipping, Rio Tinto has opted to integrate the OceanGlide system into one of its bulk carriers. This strategic decision aligns with the company’s overarching goal to embrace technologies that not only optimize operational performance but also mitigate environmental impact.
OceanGlide’s Energy-Saving Merits
Introduced in 2023, the Alfa Laval OceanGlide system has garnered significant attention within the maritime industry for its remarkable energy-saving capabilities. By reducing specific drag by an impressive 50–75%, the system facilitates substantial propulsion power savings, translating into lower fuel consumption and diminished CO2 emissions. Such performance attributes position OceanGlide as a pivotal solution in enhancing vessel efficiency while adhering to stringent environmental standards.
Rajiv Sarin’s Perspective
Rajiv Sarin, Head of Air Lubrication at Alfa Laval, expressed enthusiasm regarding Rio Tinto’s adoption of OceanGlide. He emphasized the significance of innovative solutions in driving efficiency and sustainability within the shipping sector. Sarin highlighted Alfa Laval’s commitment to supporting customers like Rio Tinto in their decarbonization endeavors, underscoring the company’s dedication to fostering a more sustainable future through cutting-edge technologies.
Optimized Airflow for Reduced Drag
OceanGlide combines air lubrication with fluidic technology to create an efficient air layer along the vessel’s flat bottom. By segmenting the surface into fluidic bands, the system enables independent control of airflow, thereby minimizing friction between the hull and water. This strategic distribution of bands ensures comprehensive coverage, eliminating passive cavities and maximizing efficiency in drag reduction.
Seamless Integration and Retrofitting
One of OceanGlide’s key advantages lies in its seamless integration with existing vessel structures. Requiring minimal structural modifications, the system can be retrofitted onto ships with ease, facilitating a smooth transition towards enhanced efficiency and reduced emissions. With no major changes or conversions necessary, OceanGlide offers a practical solution for both retrofitting and new builds, ensuring operational continuity while embracing sustainable practices.
