Collision Risk Analysis Fixed Platform and Semisubmersible
This paper summarizes the North Sea experience pertaining to mooring line failures of conventional 8 and 12 anchor line systems. Mooring system calculations, experience and test results...

Nonlinear Dynamic Response of Marine Structures Under Random Wave Loads
A simple nonlinear dynamic structure/ship model is combined with a filtered noise model of random wave loads. It is shown how this model can include (1) non-Gaussian wave elevations and...

Tension Leg Platform Response to Drag Forces by Equivalent Stochastic Quadratization
An equivalent stochastic 'quadratization' method is described for performing nonlinear stochastic response analyses of offshore platforms subject to wave and...

Towards Improved Loading Model for Design of Offshore Structures
The study presented in this paper uses geometries of different offshore platforms to quantify the effects of uncertainties in design calculations. The effect of wave directionality and...

Loading Uncertainties in Extreme Waves
Uncertainties associated with extreme base shear forces and extreme overturning moments are estimated for an idealized eight-legged jacket platform. The structure is assumed to respond...

The Concept of the New Waterway Storm Surge Barrier: Reliability as an Integral Part of a Nation's Sea Water Defense System
In the southwest of the Netherlands a storm surge barrier is to be built in the waterway that gives access to the port of Rotterdam. Strict design conditions ensure that only very slight...

Reliability Analysis for Offshore Structures
This study presents the reliability analysis of an offshore structure. The mechanical model includes various elasto-plastic diagrams with and without the combination of the normal force...

Reliability Analysis of Offshore Structures Using the Virtual Distortion Method
This paper describes a new and efficient methodology for structural reliability analysis applicable to offshore jacket structures. The proposed methodology uses the Virtual Distortion...

Progressive Failure Probability of Soil Slopes Containing Geologic Anomalies
The variability in the redistribution of stress during sliding failure of a slope is first studied. Presence of a geologic anomaly is shown to affect the failure path pattern and likelihood...

Safety Assessment of an Existing Concrete Gravity Dam
The safety and/or probability of failure of an existing 146 m high concrete gravity dam subjected to normal static and dynamic loads is evaluated. Three modes of failure were considered,...

Bayesian Updating of Axial Capacity of Single Pile
The paper outlines a Bayesian technique to update predictions of pile driving and axial pile capacity on the basis of pile driving records. The approach enables one to systematically account...

Largest and Characteristic Earthquakes in the U.S. East of the Rocky Mountains
A new statistical procedure is proposed for the estimation of maximum earthquake magnitude M in intraplate regions. Starting from a historical catalog of events and a seismotectonic classification...

Graphic Demonstration of Seismic Hazards Data Base
A seismic hazards data base has been developed as a research tool for the engineering and seismology communities. The data base presently holds five categories of data, the largest of...

Near-Field Differential Ground Displacement
An analytical model for the development of differential ground motions in the vicinity of a vertical, strike-slip fault is presented. The model considers a uniform, kinematic source model,...
