摘　　要：在航运业降碳背景下,针对营运船舶碳排放法规的要求,建立营运船舶碳排放评估数学模型,并基于某集装箱船的运营数据对现有减排措施的碳强度和经济性进行分析。结果表明:短期内通过航速管理并辅以有效的减排技术,能满足未来约10 a的碳强度评级要求,而更大幅度地降低航速会影响船舶运营成本;中长期内可通过采用混合生物燃油和加强船队管理等方式降低船舶营运碳排放,使现有船舶在营运周期内能满足碳强度评级最低要求。In the context of carbon emission reduction,to respond the regulatory requirements for carbon emissions from operating ships,a mathematical model of carbon emissions for operating ships is established.The operation of a container ship is studied based on the operational data of the container ship.The carbon intensity and economics of feasible emission reduction measures are analyzed.The result shows that in the short term,the carbon intensity rating limit for the next ten years can be met by speed management and existing emission reduction technologies,but overuse of speed reduction will go against the operating costs.In the medium to long term,the use of biofuel blends and improving fleet management may be the solution to meet the carbon intensity requirements for existing ships over their operating cycles.
