9 Summary MS Excel & Visual Basic application enables comparison of various ship and machinery concepts and operating scenarios focuses on vessel operating phase impacts predicts fuel consumption and costs, and exhaust gas emissions of a vessel for the specified operating profile and associated operating modes indicates optimal engine loads in each operating mode regarding minimum total fuel consumption, fuel cost, or exhaust gas emissions (CO 2 ) simple enough to be used in the early conceptual design phase enables more accurate calculations in later design phases if detailed information/data is available 9

10 Tool structure Enforces the user to follow a predefined step-wise process. Allows preliminary analyses as well as advanced analyses. 10

11 Main menu Starting the tool opens the Main Menu worksheet which describes the step-wise process adopted in the tool for data input and case assessment. 11

12 Fuel consumption and cost calculations The cost calculations are based on the calculated annual consumptions of different types of fuels and lube oils and the unit prices specified for the types. 12

13 Emission calculations Emission volumes from fuel combustion are calculated for CO2, NOx, SOx, CH4, N2O and PM (TSP) emissions. 13

14 Reporting By the button Results by engine types will be created a pre-defined document which contains summary of emissions from fuel combustion, fuel oil consumption and lubrication oil consumption. Summary is also shown by figures. The button Results by modes opens a dialog box in which user can select parameters to be shown in the report. 14

15 Potential tool upgrades Improving accuracy of the emission calculations Introducing new fuels, e.g. methanol Introducing of battery powered hybrid propulsion Integrating of waste heat recovery 15

16 Conclusions The tool allows predicting the annual fuel consumption, fuel costs, and the exhaust gas emissions of a vessel equipped with a specified machinery configuration for propulsion and electrical power generation, used according to a specified operating profile. Reflecting the increasing level of detail in the system design process, the evaluations can be either preliminary or advanced. The created tool enables the calculations to be performed efficiently in a half working day, or even in one hour. 16
