Container Crane Transfer Methods
Four schemes are presented for transferring container cranes around a corner: 1) transfer of crane on curved rail, 2) recessed short-radius shuttle, 3) recessed turntable and, 4) at-grade...
Structural Design of Container Cranes
The shipping industry uses container cranes to move cargo containers on and off ships. Container cranes have characteristics common to all crane structures, but many characteristics are...
Dual Hoist Container Cranes for Virginia Port Authority
The dual hoist container crane has proven to be substantially more productive than conventional container cranes. Virginia Port Authority has purchased three new dual hoist cranes with...
Innovative Bulkhead Design: Third Port Project?St. Croix, U.S. Virgin Islands
This paper describes an innovative design making use of a 'master pile' bulkhead to support the waterside rail for travelling container cranes as well as to retain...
Container Wharves Supported on All Vertical Piles Embedded in Rock-Fill Dikes
In recent years, several container wharves have been planned and/or constructed which feature the construction of the wharf over a sloping rock-fill dike. The wharves utilize all vertical...
Lessons Learned from the Certification of Graving Docks, Marine Railways, Vertical Lifts and Shipbuilding Ways
Because of the hazards which exist during the ship docking, undocking, launching and while the ship is being built or repaired, the Navy has determined a requirement exists for system...
Report of Task Committee on Drydock Design Criteria
This paper briefly summarizes the work carried out by a Task Committee on Drydock Design Criteria which was established by the Committee on Ports and Harbors. The Committee was established...
Planning for Deep-Draft Navigation Channels
This paper summarizes the trends in seaboard trade, the major commodities for the world, and the share captured by U. S. ports. The discussion includes the new developments of port planning...
Ship Wave Prediction for Port and Channel Design
Several laboratory and field investigations of ship-generated waves have been conducted during the past twenty-five years. Typically, for a given ship, reported data consists of the height...
Navigation Channel Design for Safe and Efficient Ship Transit
The U. S. Army Engineer Waterways Experiment Station (WES) recently conducted a hydraulic model investigation of the western portion of Cleveland Harbor, Ohio. This study provided data...
Louisiana Avenue Wharf E: Rehabilitate the Existing Wharf into a Container Terminal
The Port of New Orleans is currently modernizing the existing facilities in order to handle the containerized cargos, therefore enabling it to compete with other ports located on the Gulf...
Channel Design Criteria and the Houston Ship Channel
Channel design literature is reviewed and compared with operational limits currently on the Houston Ship Channel (HSC). It was found that in all aspects of channel design considered (depth,...
Additional Benefits from Channel Improvements
This paper describes techniques used to quantify three types of benefits resulting from enlarging the Houston Ship Channel. These benefit types are vessel casualty reduction, delay reduction...
National Port Issues
The adequacy of U. S. ports to meet the Nation's present and future needs was evaluated by a Committee of the Marine Board, National Research Council. The changing character...
Capacity Rating of Existing Piers and Wharves
This paper outlines a method for physically surveying the present material condition of existing piers and wharves and assigning to them a safe rated capacity expressed in displacement...
Marginal Wharf and Embankments?Seismic Design
This paper presents some of the seismic considerations used for the improvements at Berths 225 to 229 at the Port of Los Angeles. The design of the improvements was complicated by the...
Building Motion in Wind
The trend towards higher structural efficiency and hence lower cost has resulted in a generation of lighter and more flexible buildings with a lower inherent capacity for energy dissipation...
Measurement of Vertical Ground Vibrations
This paper examines the use of surface and embedded mountings, to which transducers are attached for the measurement of free field vertical ground vibrations. Upper limits to the frequency...
On the Ship's Waterways Passing Through Bridges
This paper reports on a study of bridge openings that serve as waterways, in view of the analysis of ship collision accidents. For the purpose of this study, cases of ship collision accidents...
Seismic Interaction Among Numerous Masses Founded on a Viscoelastic Stratum
The steady-state harmonic response of systems comprising numerous masses resting on a homogeneous, viscoelastic stratum with hysteretic damping is studied. The stratum, bearing on a rigid...
