On January 28, Dalian Shipbuilding Industry Corporation (DSIC) and China Shipbuilding Trading Co., Ltd. (CSTC) jointly named and delivered the second 175,000 m³ LNG carrier “Sea Nanigator”, built for China Merchants Energy Shipping (CMES). The successful delivery further enhances DSIC’s core competitiveness in the global gas carrier construction sector, contributing additional brilliance to the crown jewel of China’s shipbuilding industry.
The Sea Nanigator, independently designed and developed by DSIC, features the cutting-edge Mark III Flex cargo containment system with a daily evaporation rate of just 0.085%. Equipped with a new dual-fuel low-speed main engine and ICER system, it fully complies with the IMO’s highest emission standards.
Through optimized design and upgraded operational procedures, the vessel demonstrated significantly enhanced loading/unloading reliability during comprehensive LNG terminal testing. It demonstrates outstanding core performance metrics including speed, maneuverability, vibration, and noise levels. The cargo handling system operates stably throughout the entire process, with no anomalies detected in IS/IBS hydrocarbon monitoring. Both gas mode endurance and unmanned engine room tests were successfully passed on the first attempt, fully showcasing its exceptional safety, reliability and operational economy.
Based on the technology, construction methods, quality and management systems established by the first vessel, DSIC has continuously optimized and upgraded during the construction of the series vessels, achieving a dual leap in construction efficiency and quality. The DSIC team innovatively implemented a lean construction model, completing the ballast tank strength test in the dock for the first time while simultaneously initiating the construction of the cargo containment system, which greatly shortened the cross-operation cycle. By optimizing the berthing bunkering plan and sea trial schedule, routine sea trials and gas-carrying navigation tests were efficiently completed in just 9 days, shortening the overall vessel construction cycle by nearly two months compared to the first vessel.
In the future, DSIC will continue to drive innovation, further solidify its leading position in the marine oil and gas equipment sector, and contribute significantly to the high-quality development of China’s shipbuilding industry and the construction of the global energy transportation system.
