Terminal Development as Affected by New Generation Ships
Howland Hook Marine Terminal, New York, serves to illustrate how an existing terminal, built to the older standards, can be adapted to accommodate these larger ships that not only stretch...
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...
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...
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...
Design and Construction of Marine Facilities for Ridley Island Coal Terminal
The design and construction of the wharf for 250,000 DWT bulk carriers is discussed in this paper. The terminal project was carried out on fast-track, 23 month schedule, with construction...
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...
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...
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...
Tunnel Ceiling Replaced over traffic
The ceiling of the Holland Tunnel under the Hudson River, connecting New Jersey and Manhattan, was 59 years old and needed replacement, a big job because there are 3 miles of ceiling in...
Predicting Radon Transport by Vegetation
Establishment of a vegetative cover on waste sites containing **2**2**6Ra (Radium) may provide conduits for transport of **2**2**2Rn (Radon) out of the waste into the above-ground environment...
Design of Final Covers for Landfills
Final covers or caps are incorporated into a completed landfill to limit the amount of moisture percolation through waste materials. A properly designed final cover system provides the...
Models of Organics Transport Through Soil Columns
A mathematical model is proposed for the transfer of organic solutes in soil. Two cases are considered namely transport of non-adsorptive solutes and transport of adsorptive solutes. Comparative-study...
Modeling the Movement of Volatile Organic Chemicals with Unsaturated Flow
Over the past decade, the rate of groundwater contamination by volatile organic chemicals (VOCs) has increased. Therefore, for both groundwater protection and cleanup, it is necessary...
Engineering Methodology for Delineating Debris Flow Hazards in Los Angeles County
Utilizing historical and field data, elementary geomorphology and simplified hydraulics of debris flows, a mapping strategy has been developed. The delineation procedure includes defining...
Flood Risk Below Steep Mountain Slopes
Alluvial fans spread at approximately the critical hydraulic slope below apexes at canyon mouths. Periodic torrents that rage out of the canyons are devastating at the apex and have diminishing...
Debris Flows and Hyperconcentrated Streamflows
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that...
An Evaluation of Sediment Resuspension Parameterizations
The recent attention to managing surface water toxic substances has resulted in a number of modeling approaches, all of which to a great or lesser extent require accurate treatment of...
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...
