Trends in Containerships and Their Impact on Terminal Design
A revolution in ocean shipping operations, affecting both landside equipment and cargo handling methods, is underway. In today's container shipping industry, maximum efficiency...
Systematic Design of Marinas for Ice Condtions
A systematic approach and recommendations are presented for design engineers use in planning and building safe docks and marinas, and in reducing the expense of damages which ice causes....
Mobile Cranes on Barges?A Naval Architect's Perspective
The purpose of this paper is to present a procedure for analyzing the effect of heel on a barge/crane combination in order to determine its suitability for lifting a load of given size...
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...
Recent Trends and Advances in Bulk Cargo Unloading
The progress in loading of bulk cargo into ships has matched the advances in ships' size. The same could not be said for getting bulk material out of the hold of a ship, in...
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...
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...
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...
Seismic Design of Earth Retaining Wharf Structures
Seismic design considerations pertinent to earth retaining wharf structures are reviewed. These considerations include: evaluation of the seismic environment and design earthquake ground...
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...
Geotechnical Aspects of Stiff and Hard Clays
This publication contains articles that deal with field and laboratory measurements of engineering properties of stiff (overconsolidated) clays, and comparisons of predicted and measured...
Tallying Water Resources Goals
Federal water resources planning philosophy has undergone a lengthy evolution with a number of refinements in the past decade to encompass environmental laws and the political philosophy...
CAD Mapping Trailblazer
Until three years ago, few civil/surveying firms had automated both surveying (including digital recording of angles and distances shot in the field) and the related design and drafting....
Pressuremeter and Foundation Design
The design of shallow and deep foundations on the basis of pressuremeter results is analyzed using numerous load tests and case histories. The foundations are shallow footings subjected...
In-Situ Testing of Peat
It is often economical therefore to start geotechnical investigations with a study of maps and serial photographs and to continue with a detailed program of field reconnaissance. Standard...
Reliability of Pile Capacity Assessment by CPT in Overconsolidated Clay
Correlations for unit skin friction and end bearing are established between cone penetration test (CPT) records, triaxial data and a small data base of measured skin friction and end bearing...
Use of SPT and CPT Tests for Evaluating the Liquefaction Resistance of Sands
A cone penetration test (CPT)-liquefaction resistance relationship has been established using the large body of standard penetration test (SPT) data. Factors for relating CPT tip resistance...
Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...
Probabilistic Study of SPT Liquefaction Analysis
The influence of earthquake magnitude upon the commonly used correlation between Standard Penetration Test (SPT) blow count and liquefaction potential is evaluated using a probabilistic...
