On May 8, the world’s first 24,000 TEU methanol dual-fuel container vessel, MV OOCL WISDOM, was officially named in Nantong, Jiangsu Province.
This maritime giant was custom-built for Orient Overseas Container Line (OOCL) by COSCO SHIPPING Heavy Industry. Its completion marks COSCO SHIPPING’s advancement to the global forefront in the field of ultra-large clean energy vessels.
MV OOCL WISDOM has an overall length of 399.99 meters and a molded breadth of 61.3 meters, with a total deck area equivalent to 3.5 standard football pitches. When fully loaded, the hull’s height is comparable to a 22-story residential building. The maximum carrying capacity reaches 24,168 TEUs, with a deadweight of 225,000 tons and a service speed of 22.7 knots. If these containers were lined up end-to-end, their total length would approach 150 kilometers.
MV OOCL WISDOM is equipped with the world’s largest-capacity methanol dual-fuel power system, featuring the world’s largest methanol dual-fuel main engine, auxiliary engines, and boilers. It can flexibly switch between methanol and conventional fuel during navigation. When powered by green methanol, the vessel achieves full life-cycle carbon neutrality. A single vessel is estimated to reduce CO2 emissions by approximately 150,000 tons annually, equivalent to the carbon sequestration effect of planting 820,000 trees. The sulfur oxide emissions are reduced to near zero, and nitrogen oxides are significantly decreased for the vessel, effortlessly complying with the world’s most stringent environmental standards.
The vessel is equipped with a full-stack intelligent control system independently developed by COSCO SHIPPING, fully meeting the highest-tier requirements for smart ships and cybersecurity of the American Bureau of Shipping (ABS). Notably, the intelligent energy efficiency management system automatically optimizes speed and power based on sea conditions and deadweight, and paired with a permanent magnet shaft generator, it reduces both carbon emissions and operating costs. The hull structural intelligent monitoring system conducts “health checks” 24/7, proactively predicting “fatigue damage.” Meanwhile, the wireless intelligent monitoring and control system for reefer containers will automatically trigger alarms under abnormal conditions, ensuring greater reliability in cold chain transportation.
The flammability, explosiveness, and certain toxicity of methanol are widely recognized challenges within the shipping industry. To tackle these challenges, the project team at Nantong COSCO KHI Ship Engineering built a comprehensive, multi-dimensional safety protection line spanning from fuel tank structural safety and gas dispersion analysis to high-pressure water monitors and CO2 fire extinguishing systems. Gas concentration monitoring systems are installed in all key areas on board; once methanol concentration levels become abnormal, the system will immediately trigger an alarm and activate emergency response protocols. Tens of thousands of extreme sea condition simulation tests were ultimately conducted to ensure the safety and reliability of every future ocean voyage.
