Analysis of Causeway Ferry Dynamics for Safe Operation of Improved Navy Lighterage System
Amitava Guha, Abhilash Somayajula and Jeffrey Falzarano
The causeway ferry is a modular arrangement of multiple powered and unpowered barges, which is used for transportation of vehicles and heavy cargo from open ocean to undeveloped shores. The non-linear connections between the modules and the combined motion of the system are of interest for safe operation. A numerical simulation of the causeway ferry with four barges using AQWA is made to understand the motion behavior and estimate the loads on the connectors. Effect of shallow water, shielding effect due to multi-body, and second order drift forces are presented here.
