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.”

PED Crane and Infrastructure Upgrade Project: Overview and Lessons Learned

This presentation provides an overview of a recently completed low profile crane project at Port Everglades involving procurement of three of the largest low profile cranes in the world and installation of a new crane rail girder system to support these cranes. The presentation describes an overview of the project including crane and girder systems, design and construction issues encountered, and key lessons learned.

STS Crane Stowage Design: Key Considerations and Case Study

There have been devastating ship-to-shore crane failures due to failure of the stowage systems during hurricanes. The design of these systems is complex, requiring an understanding of how the wharf stowage hardware interfaces with the crane hardware, both to facilitate connecting and disconnecting the hardware, and to account for subtle but significant loading conditions that occur. This presentation aims to provide a broad knowledge base for designers of such systems and presents a recent project case study to illustrate some design and construction challenges. 

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.

Your Wharf May Be Stronger Than You Think

This article discusses using modern engineering methods to justify additional crane girder capacity. As many terminals face the challenge of accommodating larger vessels and cranes, many wharf owners find that they have insufficient crane girder rated capacity and only consider strengthening options. Larger wharf capacities can be justified using modern engineering methods.

High Performance Pile Connection: McNears Beach Park Pier Repair

This paper presents the repair of a damaged wharf structure by replacing the pile connections with a recently developed high-performance connection, which allows for flexible rotation. Testing by the University of Washington has shown that these connections perform significantly better during seismic loading than a classical pile connection.
