Current Blockage Effects on Model-Scale Offshore Platform
This paper presents analysis results of model tests on a 1:47 scale model of an offshore jacket structure under wave-plus-tow (representing wave-plus-current) conditions. The analysis...
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...
The SIMBAT Software Package for Stochastic Interpolation of Ocean Wave Kinematics as an Aid in the Engineering Design of Large Floating Structures
Geostatistical techniques of nonconditional and conditional simulation are used in a new public domain computer software package, named SIMBAT, to stochastically interpolate ocean wave...
Three-Dimensional Circulation Modeling of the Coastal and Ocean Environments
Incursion of the loop current, a meandering feature of Gulf of Mexico large-scale circulation, may produce large hydrodynamic forces on the offshore structures. The present study is to...
A New Concrete Armor Unit for Breakwaters: The Beta Block
The aim of this paper, is to present a new artificial block for the protection of breakwaters. This armor unit, named BETA, has been designed and tested in the Coasts and Harbors Studies...
Hydraulic Design of Offshore Breakwater in Sergipe, Brazil
A Petrobras (Petroleo Brasileiro S.A.) marine terminal was recently constructed in Sergipe, Brazil (Figure 1). The offshore breakwater was initially designed in a conventional way, but...
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)...
Mobile-Bed Physical Model Tests for the 1992 Olympic Harbour
The undistorted physical model is described which allowed the measurement of the wave induced velocity field along the main breakwater, and also in Somorrostro Beach (Barcelona). The current...
Piles Under Dynamic Loads
This proceedings,
Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...
MUT1D: User-Friendly One-Dimensional Thermal Model
MUT1D is a microcomputer-based heat conduction model which uses implicit finite difference techniques to determine the thermal regime and track the movement of the phase change front in...
Computer Predictions of Thaw Beneath Gravel Embankments on Warm Permafrost
A computer model was used to simulate the freeze-thaw effects of gravel embankments on warm permafrost typical of south-central Alaska using a one-dimensional finite-difference code, FREZ1D....
Impact of Cold Weather on Building Construction Scheduling
Weather impact on a building construction schedule is often significant in cold regions. Most deterministic scheduling methods are unable to directly account for the effects of weather...
Ice Jam Configuration: Second Generation Model
An early model of ice jam configuration in wide, prismatic channels is generalized for applications to natural streams. Test runs are carried out to illustrate model performance and study...
Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...
A Conceptual Model for Vertical Frazil Distribution in Turbulent Flows
A conceptual model is presented for the evolution of frazil over depth in a turbulent flow. The net upward migration due to buoyancy of the frazil is opposed by intermittent mixing induced...
A Two-Dimensional Surface Drift Model for River Ice
A two-dimensional surface drift model for river ice with low ice discharge conditions is presented. The model is applied to the Grass Island Pool area of the Niagara River and compared...
River Ice Cover Cracking for Various Boundary Conditions
The breakup of river ice covers is commonly initiated by the formation of cracks parallel to river banks. These cracks usually result from a change in the water level due to a rapid rising...
Fractal Crushing
This paper develops an approach to a two-dimensional fragmentation process, in which floating ice floes are driven against each other and break up into smaller floes. It first considers...
Effect of Grain Size Variation on Damage in Polycrystalline Ice
This paper studies the effect of grain size distributions on damage accumulation in polycrystalline ice under uniaxial compression. The numerical results are derived from the internal-variable...
