CII对某超大型集装箱船设计影响分析

Analysis of the Impact of CII on the Design of a Certain Super Large Container Ship

基于营运碳强度指标(CII)和能效设计指数(EEDI)对集装箱船的影响,以某16000 TEU级别的超大型集装箱船为研究对象,从船型优化、船尾节能导管的应用、燃料的选取、新型节能措施的应用等方面对该船型CII和EEDI进行对比分析。结果表明:船舶降速营运可提高CII评级级别,是被动措施;采用LNG双燃料方案,到2030年船舶无需降速运营,CII评级状况能保持“B”,是班轮公司降低碳排放的中短期最优解决方案。

Based on the impact of the Carbon Intensity Index(CII)and Energy Efficiency Design Index(EEDI)on container ships,a 16,000 TEU ultra-large container ship is taken as the research object.The CII and EEDI of the ship are compared and analyzed in terms of ship type optimization,application of energy-saving ducts at the stern,fuel selection,and application of new energy-saving measures.The results indicate that reducing ship speed during operation can improve the CII rating level,which is a passive measure;By adopting the LNG dual fuel scheme,ships will not need to operate at reduced speeds by 2030,and the CII rating status will remain at"B",making it the best solution for shipping companies to reduce carbon emissions in the short to medium term.
