In 1978 the Port of Oakland commenced a project to demolish the old Berth 5, 6 & 7 break bulk sheds, portions of the wharves, and the warehouses behind, and to construct container...
Gabon Mineral Port Master Plan?A Case History
The integrated design of infra-structure and superstructure of marine terminals for bulk cargoes presents opportunities for innovative solutions that can produce substantial economic benefits....
Port Master Plans and Feasibility Studies
Port projects are cost-intensive long-life irreversible assets, and developing countries particularly limping with resource constraints could not afford the luxury of short-sighted defective...
Gabon Mineral Port Planning
There has been increasing interest in the use of topping-off and top-loading vessel transport systems to ease the burden of expenditures for deepening harbors to fully load large vessels....
Port of Long Beach Supertanker Terminal
The supertanker marine terminal and crude-oil transfer facility at Berth 121 on Pier E in the Port of Long Beach, California is the largest tanker-handling berth on the West Coast. This...
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...
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
