Barge with cranes approaching Verrazano Narrows bridge upon departing Newark  

Project Summary

Three low profile container cranes were relocated from Newark, NJ, to Tampa, FL, using the cargo barge Atlanta Bridge. After loading and securing the cranes, the tug East Coast towed the barge to Tampa under favorable weather conditions, with a tow speed averaging in excess of 8.5 knots. The highest waves encountered during the 7 day tow were reportedly no more than 3 ft, well below the design significant wave height of 13.7 ft. 

Scope of Work

The project scope included:

• Determine design environmental criteria for the tow;

• Modeling of the barge hull for the motion response analysis;

• Calculate the design barge motions and resulting inertia loads on the cranes.
