Return Velocities Induced by Shallow-Draft Navigation
Return velocities are caused by the displacement effects of vessels as they travel in navigation channels. Numerous return velocity equations have been developed for relatively small channels...

Numerical Modeling of Proposed Channel Designs (J. F. Baldwin III), California
Ship simulator studies of proposed improvements to navigable waterways are a very important part of any assessment. The John F. Baldwin Channel (JFB) Project (Phase III) is a ship channel...

Hydrodynamics and Mass Transfer in a Jet-Agitated Vessel
Experiments of carbon dioxide absorption in water have been carried out in a turbulent vessel presenting a zero mean shear stress value at the gas-liquid interface. Liquid-phase turbulence...

Using Real-Time Location Information for Hazardous Materials Shipments
Real-time location information on shipments of hazardous materials can be used to update routing decisions while the shipments are in transit. The effects of unforeseen delays, accidents...

Marina Del Rey: 30 Years of Environmental Impact
Marina del Rey - the world's largest man-made recreational boating harbor - also holds primacy in pollution. Marina del Rey is home port to more than 6,100 vessels in wet...

A Case Study of Propeller-Induced Currents and Sediment Transport in a Small Harbor
The operation of vessels in marinas and small harbors can provide important driving forces affecting ambient circulation patterns and current speeds near the bottom. The case study on...

Shallow Draft Coastal Port Design
One of the U.S. Army Corps of Engineer (USACE) missions is to construct and maintain shallow draft coastal ports and harbors. Defined as less than 20 ft, shallow draft projects number...

Conflicts Between Pleasure Boats and Fishing Boats at Marinas in Japan
At present, some half of the marinas operating in Japan have conflicts of various kinds relating to the navigation of pleasure boats. This study discusses the findings of a study on 365...

Towards Reduction of the Vulnerability of Multi-Tank Storage Facilities
Accident scenarios in large scale industrial plants show that conventionally designed multi-tank storage facilities are susceptible to domino effects. With the aim to reduce the probability...

Pressure Vessels for Space Station Freedom
Space Station Freedom (SSF) will utilize more than 10 different types of pressure vessels for storage of oxygen, hydrogen, nitrogen and mixed gases at operating pressures ranging from...

State of Nevada Nuclear Waste Shipping Cask Design Studies
The State of Nevada has sponsored several contractor studies regarding nuclear waste shipping cask design issues. A comprehensive transportation needs assessment completed in 1988 recommended...

Analysis of RADTRAN Transportation Model
The RADTRAN computer model, used to estimate the risks of transporting waste to a high-level repository, is critically reviewed. Ignoring high consequence accidents, human error, sabotage,...

Studies on the Physical Effects of Commercial Navigation Traffic in the Upper Mississippi River
Changes in water velocity caused by passage of commercial navigation vessels were measured 180-500 ft (55-152 m) from shore at River Mile (RM) 504.8 in Pool 14 of the upper Mississippi...

U.S. Coast Guard Experience with Commercial FRP Vessels with Respect to Structural Reliability
The U.S. Coast Guard currently inspects over 1000 fiber reinforced plastic (FRP) vessels used in commercial passenger service. The designs include monohulls, catamarans, hydrofoils and...

Water Jets Fight Silt
In the largest U.S. application to date, an array of hydraulic jets is being used to scour a ship berth at the Port of Grays Harbor on the coast of Washington. The system has been in place...

Moving Intermodal Containers Over Urban/Suburban Highways
Due to standardization, to date most containers basically fit the U.S. highway environment, which was the entire original intent of intermodal transport. The paper presentes the results...

Floating Membrane Supertankers: Are They Feasible?
Optimal shapes of long cylindrical membrane containers are obtained by restricting the circumferential membrane stress to be tensile and constant throughout the tanker. Optimality is achieved...

Analysis of Barrier Island Dynamics for Ship Channel Planning at Ship Island, Mississippi
Ship Island is located among a chain of barrier islands approximately 18 km south of Biloxi, Mississippi. During initial construction of Gulfport Harbor Ship Channel, 1901-1905, the channel...

Environmental Impact of the Stranding of a Freighter Ship in the Parque Nacional Marinho Dos Abrolhos, Bahia, Brazil
The Abrolhos Marine National Park was created by presidential decree no. 88,218 of April 6, 1983 encompassing two distinct areas of the southern coast of the State of Bahia, Brazil, with...

Fast Track, Instant Track
