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.

Manson and Liftech have collaborated on several design-build projects. This presentation discusses the latest design-build project from their perspective, including the bid process, the design, and the construction.

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.

This paper and presentation presents what happens when wharf crane girders are subjected to extreme loads near or beyond their calculated design capacity, the performance that can reasonably be expected when extreme loads occur, and when extreme loads should be considered in the design of wharf crane girders.

This presentation discusses the findings of a seismic capacity study of a recently designed and constructed wharf (Berth 59) at the Port of Oakland (Port).

Floaterm is a concept that helps alleviate congestion and pollution. This presentation discusses two variations of Floaterm concepts: midstream and ship-in-a-slip operations. Engineering calculations have been prepared to verify the technical feasibility of the concepts, but are not included here.

This presentation explains why forces vary between corner tie-downs and introduces the ductile link—one method to improve the reliability of new and existing tie-down systems.
