Justify Larger Crane Girder Capacity
Presented by Erik Soderberg at the Port Equipment Manufacturers Association (PEMA) 2020 Technical Webinar titled “Views and technical challenges for the new generation of ship-to-shore and yard cranes.”
Port Everglades Large Low Profile Cranes and Wharf Expansion Design
Published in World Port Development, May/June 2021
In Situ Boom Extension Process
This paper introduces a concept rig and procedure to extend a container crane boom without a land-based or floating crane.
Seismic Response of Large Pile Moored Floating Structures
Pile moored floats are usually not analyzed for seismic motions, since they are often thought to be mostly isolated from ground motions due to the flexibility of the piles and the resistance of the surrounding water. To confirm this assumption for several projects, the authors performed simplified time history analyses on multiple floats to study the effects of water resistance, soil damping, and the gap between the pile and float.
Key Design Issues for Large Low Profile Container Cranes
This publication discusses key design issues and solutions for projects in Australia, Florida, and Massachusetts. Issues include crane and component weights, geometry constraints, wheel loads, skidding, and fabrication challenges.
Seawall Movement and Piling Design at the San Francisco Waterfront
This publication discusses methods and findings for the San Francisco Fire Department’s floating fire station, including challenges encountered and suggestions for future projects.
Wharf Upgrade Considerations for Large Low Profile Cranes
This publication presents key considerations for the infrastructure supporting large low profile cranes, including large crane girder and pile capacities, electrical demands, and construction challenges associated with the project, such as phased construction and daily coordination to avoid interruptions to the operations. The focus is on the Port Everglades Department of Broward County new crane girder and wharf upgrade project, which covers about 1 mi (1.6 km) of waterfront.
Balance Crane, New Concept
This article discusses the Balance Crane, a new concept that can reduce the weight and wheel loads of very large STS cranes.
