In the context of carbon emission reduction,to respond the regulatory requirements for carbon emissions from operat-ing 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 oper-ating 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.
