On April 15, Hudong-Zhonghua Shipbuilding, a subsidiary of China State Shipbuilding Corporation (CSSC), officially delivered the world’s largest dual-fuel LNG container ship, the CMA CGM SEINE, in Shanghai. This milestone marks a significant achievement in green maritime technology. The CMA CGM SEINE measures an impressive 399 meters and boasts a capacity of 23,876 TEUs, including 2,200 slots for refrigerated containers. Equipped with an 18,600 cbm MARK III membrane LNG tank, the ship is capable of traveling 19,500 nautical miles on a single LNG voyage, achieving a reduction in CO₂ emissions by 20% while nearly eliminating sulfur oxides and particulate matter. This vessel is an upgrade from the earlier CMA CGM Jacques Saadé-class, offering greater loading capacity with an additional 764 TEUs. It also boasts reduced fuel and gas consumption while meeting IMO Tier III and the latest SOLAS regulations. Enhanced fire safety systems and a noise-reduction design for crew comfort underscore its advanced features. With the delivery of the CMA CGM SEINE, Hudong-Zhonghua has now completed 17 container ships for CMA CGM, with 12 being LNG dual-fuel powered. This achievement solidifies the company's leadership in constructing environmentally friendly, ultra-large vessels. This project highlights exceptional performance through digitalized production and efficient management, setting records in outfitting, LNG bunkering cycle, and construction period. This showcases Chinese shipbuilding excellence, with more vessels on track to launch in 2025. The future of ultra-large green shipping is promising and firmly anchored in Shanghai.
