Evaluation of the Floaterm Concept via Simulation

1. Evaluation of the Floaterm Concept via Simulation Dulebenets M., Deligiannis N., Flaskou M., Sarker A.

2. Introduction • How to meet growing demand at marine container terminals? • Floaterm concept (Ashar, A. and Liftech, Inc. early 2000) • Feasibility study by Delft University (the Netherlands) • Concept originally applied at the Ceres Terminal (Amsterdam, the Netherlands) in 2002

3. Study Motivation • Quantify new concept benefits (if any) • Savings in equipment • Investment and operational costs • Quay crane (QC) productivity and makespan

6. Data • The main terminal characteristics: ITV: Internal Transport Vehicle RTG: Rubber Tyred Gantry Crane • 12,000 TEUs per vessel • Various container composition (import/export/transshipment)

7. Scenario Analysis • 3 data sets varying: • # of on-shore QCs (3, 4, 5); • # of off-shore QCs (1, 2, 3); • container composition • Transshipment: 25%, 33%, 40%, 50%, 60% • Import/Export: 50%-50% split of remainder • QC productivity = F(ITV, GC) • Function established via simulation • 20-year economic analysis

8. Findings: FMT vs CMT • 19.4% less Yard Trucks (YTs) and 24.0% less Automatic Lift Vehicles (ALVs) • 10.6% and 19.0% less Gantry Cranes (GCs) with YT and ALV deployment (respectively) • Lower costs for site development and operations (especially with high transshipments) • Higher cost for equipment

9. Findings: FMT vs CMT • Average QC productivity • With YT: 35.7 moves/hour (8.6% higher than CMT) • With ALV: 38.2 moves/hour (1.0% higher than CMT) • Average savings over 20-year • With YT: $44.12 million • With ALV: $17.27 million • The FMT will facilitate handling of mega-containerships

11. Future Research • Effects of buffer area size at seaside/marshaling yard on the terminal performance; • Sensitivity analysis for various ITV speeds, QC and GC configurations; • Mixed ITV gang deployment; • Handling of import containers by off-shore QCs; • Model a mid-stream application of the floaterm concept;
