1. Diamond and Sapphire – Energy Savings

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
2

3. Background Data
• Diesel & GT Mfg Data - efficiency
• ENIRAM Power/Speed Curves – regression lines
• SFOC Efficiency Curves – extrapolation
• F4 & F8 Fuel Plans – fuel rates/totals
• Technical Consumptions Analysis – actual power, speed,
consumption
3

4. Port Operation
• Power Requirements
• 1 AC = 9750 kW
• 2 AC = 11700 kW
• Options
• Current – 2x 8L46C
• ADG - Use 1x larger DG
= more optimal efficiency
• Savings
• 1246DF = $2.3M
• 1246F = $1.55M
• 16V31DF = $1.55M
