HarborSym: Simulation Model for Deep Draft Navigation Improvements



Start Date:  Sep 2004

End Date:
 Oct 2007






Problem Addressed:  

The Corps is responsible for maintaining navigable channels leading into the nation's coastal ports and harbors. As new, larger ships enter the world fleet, existing channels may require deepening or widening or new channels may need to be created. Establishing the need for such modifications requires detailed economic analyses. Assessing the benefits of such modifications requires a holistic examination of vessel traffic into the port, which can best be achieved through a simulation model.





The overall objective of this project is the continuing development and improvement of the HarborSym model. Specifically, additional modules are being developed to support HarborSym deep draft navigation analyses. To assist with the input data requirements and development of future shipment lists, a Vessel Call Analyzer and Commodity Driven Forecast Tool will be created. The HarborSym Animation Module (HSAM) provides post processing visualization of HarborSym outputs through three dimensional avatars. After the widening version of HarborSym is fielded, a version will be developed to calculate the benefits of deepening a channel.




Benefits of this project include allowing users to analyze changes within a port system without modifying complex computer codes. Users will be able to create models for specific harbors using a graphic interface and populate and manage information related to port infrastructure, traffic movements and harbor rules. Vessel movements will be animated during the simulation, thereby making it easier for users to determine if the model is accurately representing their system. Through the post processing visualization module, HSAM, the model capabilities and outputs can be demonstrated to decision makers and stakeholders. The model will enable planners to more accurately predict the benefits of channel-widening projects. It will provide a "transparent" approach to channel-widening analyses that can be duplicated by outside researchers.






The beta version of the HarborSym widening model and HSAM visualization tool can be downloaded from the HarborSym website (see below). Training has been conducted successfully and is offered trough the DD-PCX in Mobile, AL. The model is currently being fielded on two USACE channel widening studies. Work has begun on the Vessel Call Analyzer, Commodity Driven Forecast Tool, and deepening version of the model.
