GPA s FY2012 ertg Electrification Project 12
ertg Economical Fuel Saving Concepts Conventional RTG s are not very fuel efficient Fuel consumption examples: Conventional Ecological RTG RTG 7 l/h Ecological RTG + Super Caps 5.2 gph 3.4 gph 1.85 gph Electrified RTG s about 3 kwh/move Solutions: Intelligent variable-speed generators can save up to 35% of fuel costs Intelligent port planning and efficient RTG operation reduce costs Electrification Fuel and Maintenance Cost Reduction + 0 Emissions 13
Economical Fuel Savings Concepts Current cost/gallon: $ 3.13 15 container moves/hour = 5.2 gallons Cost/hour: $ 16.28 Cost/year: $ 58,606 Current cost/kwh: $ 0.09 15 container moves/hour = 35 kw Cost/hour: $ 3.15 Cost/year: $ 11,340 Even with current oil prices being much lower than during peak 2008, electrification produces significant cost savings for energy of up to 80%. Additional savings for the reduction in maintenance costs associated with diesel generators: Typical numbers are: Maintenance cost per operating hours ($2.55 per hour) Tier 4 Diesel replacement @ 25,000 hours ($6.00 per hour) 14
Environmental CO 2 Emissions in Ports Diesel RTG CO 2 emissions/year: Electric RTG CO 2 emissions/year: 1,000,900 pounds 414,470 pounds In reality, E-RTG s run on about 90% electric and 10% diesel (block changes and maintenance). Therefore: E-RTG = 474,000 pounds of CO 2 per year CO 2 reduction of ~52% 15
Conductor Rail Solution 0852 Drive-In References Wampfler s new generation of drive-in automation Test unit as installed at Kone s test facility in Hyvinkaa, Finland GPA to install same unit on their four ertg units as part of the ertg demonstration project. Project start-up date is October 1, 2012 16
ertg Conductor Rail Solution 0851 Drive-In Automated Drive-In system No electricians or specialized personnel required Very little down time Drive-In procedure 2-3 minutes Rigid during drive in flexible during operation Absorbs large working tolerances Including safety concept (e.g., slow down during engaging full speed during normal operation) Collector Trolley remains on RTG Trolley moves freely on steel frame No manual plugging required 17

Summarizing Garden City Terminal s ertg Plan GPA will be constructing an ertg demonstration project beginning August 1st Initial phase will be to test two ertgs in a backto-back arrangement beginning about September 30th Next phase will be to test four ertg cranes across 4-stacks utilizing the automatic drive-in feature ertg Intent is to then begin implementation of the ertg concept to all of container berths CB1, 2, and 3 during FY 2014 All of the Garden City Terminal will be converted to ertgs over the next four years 19
