A Three-Dimensional Simulation of Buoyancy and Wind-Induced Circulation and Mixing in the New York Bight
A three-dimensional simulation of the circulation and mixing in the New York Bight has been conducted, forced by (i) wind stress for the year 1987 and monthly-mean heat fluxes at the sea...
Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...
Sampling Errors in U. S. Extreme Wind Records
A study of design level extreme wind speeds showed that sampling errors were the primary cause of station to station variability. A method for decreasing sampling errors in design wind...
TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...
Port of Portland's Berth 601 Floating Dock
The Port of Portland's facilities, being located on the Columbia and Willamette Rivers, are subjected to extreme water level fluctuations. Over the years, the Port has used floating docks...
Pile Lateral Load Test in the Port of Los Angeles
Recent wharf projects in West Coast ports have featured rock dikes to contain backland fill and the use of vertical piles embedded in the rock dikes to resist lateral loads. This paper...
U.S. Navy Deployable Waterfront Facility
The U.S. Naval Civil Engineering Laboratory (NCEL) has been developing the concept of a Deployable Waterfront Facility (DWF) as part of its technology development programs for the enhancement...
Environmental Monitoring and Operator Guidance System (EMOGS) for Shallow Water Ports
Port facilities have increasingly been required to accommodate longer and deeper draft ships. Existing approaches to many ports consist of long shallow channels which can make transits...
Risky Business: Can We Believe Port Risk Assessments?
What is the risk that a maritime incident resulting in catastrophic consequences (environmental damage or loss of life) could occur in a U.S. port or waterway? How does one calculate the...
An Overview: Wetland Restoration, Protection, and Establishment by Beneficially Using Dredged Material
Dredged material has been used beneficially by mankind for many years; in the past two decades it has purposely been used to restore and protect existing wetlands, and to establish new...
Wave-Current Interaction with a Large Structure
The effects of a current on the diffraction of regular waves around a three-dimensional body are examined by a time-domain method. The Froude number is assumed to be small so that the...
The Mother of All Resilient Structures: Fixed-Base Tower in 3000-Foot Water and Some Outstanding Issues
This paper describes design and development work for 40- to 80-well fixed- base - yet compliant - towers for 2000- to 3000-foot water depths. Technical issues which are covered include:...
Wave Exciting Forces on a Platform Fixed in Nonlinear Shallow Water Waves
This paper presents the result of an experimental observation of cnoidal waves and the nonlinear wave loads on a fixed barge in a 2-dimensional wave tank. The Ursell numbers of the waves...
Broadside Current Forces on Moored Ships
A method of estimating the static lateral current force on ships in deep and finite depth water is presented for the case of the current broadside to the ship. The method is based on recent...
Wave Effects on Offshore Structures?Some Recent Research
The present paper summarizes methods of estimating wave effects on offshore structures, and highlights a selection of recent related research. Initially, certain aspects relating to the...
Probability of Wave Force on Horizontal Members
This study is motivated by the works of Isaacson and Subbiah (1990) to evaluate the vertical wave force on a rigid horizontal member located in the vicinity of still water level with its...
Reliable Design-Wave Force Predictions for Seabed Pipelines
The results of three separate field research projects have been pulled together to provide a design formula for maximum wave-induced horizontal force on a submarine pipe. This broadly-applicable...
Static Wave Force Procedure for Platform Design
Since results from the Ocean Test Structure were presented at Civil Engineering in the Oceans IV in 1979, there have been numerous laboratory experiments and a few full-scale measurements...
Wave Slamming on a Horizontal Circular Cylinder
The present paper describes an experimental study of the wave slamming force on a horizontal circular cylinder located near the free surface. The vertical force on a cylinder and the corresponding...
Stability of Accropode(R) and Comparison with Parallelepipedic Block
This paper describes the tests which were performed on physical models with irregular waves, to determine the hydraulic stability of the Accropode(R)...
