Lloyd's Register: Ship Engine Retrofits Market Dependent on Regulatory Framework

Lloyd's Register (LR) states that the future of ship engine retrofits hinges on regulatory developments promoting zero-emission fuels. Despite advancements in retrofit technology, uncertainty in regulations is hindering large-scale conversions. In 2025, few retrofit projects were announced, though technical viability is evident, exemplified by the methanol retrofit of the COSCO Shipping Libra. Engine manufacturers like Wartsila and WinGD are broadening retrofit options. LR emphasizes that clear regulatory signals are crucial for investment and market growth.
