2. Current Problem
• High port load
• In port average load = 11MW
• 9L46C max load = 9.54 MW
• 8L46C max load = 8.40 MW
• Low total DG output – requires GT operation (MGO)
• 4x DG capable of only ~17kn
• On average 30% of time underway spent running GT for DI & SA

20. DG Specifications
• 12V46F
• 173 Tons
• 16V46F
• 233 Tons
• 16V31DF (x2)
• 85 Tons
• New benchmark in efficiency and overall emissions performance

High Port Load:
In port requires 9750 and 11700 kW and we currently use 2x 8LW46
An option to save money in port would be to use a larger DG which can perform at a more optimal efficiency which can save a large amount.
Low DG Output
30% of underway is spent above 17 knots which is higher than what our current engines can run at so we run the GT a fairly significant amount
I adjusted the fuel curves to better reflect the given loads. Originally the data was graphed as a line graph but I changed it to a scatter plot to better see a relationship between Load and SFOC
