Ebb Delta and Shoreline Response to Inlet Stabilization, Examples from the Southeast Atlantic Coast
Analytical studies were performed on the geomorphic evolution of four stabilized natural inlets located along the ebb-tide dominated, barrier island, southeastern coast of the United States....

A Re-Evaluation of Earthquake Hazards Within the California Coastal Zone: Lessons from the Loma Prieta Earthquake
The 7.1 magnitude Loma Prieta earthquake occurred on October 17, 1989, had a duration of 15 seconds, and took 62 lives. Among the lessons learned from this earthquake with regard to offshore...

Development of Long Beach Downtown Marina
This paper describes the planning and construction of the new Alamitos Bay Marina just offshore of Long Beach's downtown shoreline. From an engineering standpoint the construction...

Mitigation for Offshore Development/Fishing Conflicts
Three case studies, WestGold gold dredging offshore Nome, Alaska, Endicott Causeway off Alaska's North Slope, and Platform Irene offshore California, show that project related...

Santa Barbara County and Offshore Oil Development—Applicability of the Lessons to Other Communities

Beach Erosion in Japan and Its Classification
Beach erosion in Japan is investigated in a nationwide scale and the causes are classified into six categories. Of six categories the most important factors are 1) obstruction of continuous...

Offshore Platform Structural Verification and Requalification—The Regulator's Viewpoint of Aging Platforms
The regulator's viewpoint of the structural verification and requalification of aging offshore oil platforms is crucial to the continued production of oil and gas. For the...

Reliability Analysis in Estimating Turbulent Wind Force on Offshore Structures
This paper presents the results of a reliability analysis carried out to estimate low frequency turbulent wind drag force (including extreme values) acting on a floating offshore structure....

On the Reliability of Offshore Platforms Against Random Sea Waves and Earthquake Motions
Dynamic response of offshore structures to random sea waves and strong earthquake motions is investigated. The wave-structure interaction is represented using the generalized Morison equation...

Spectral Analysis and Fatigue Reliability Assessment for Offshore Structures
This paper presents a cumulative fatigue damage formulation in stochastic variable space using bilinear SN model and the Palmgren-Miner's rule for evaluating the fatigue reliability...

Response Surface Fitting in Offshore Structural Design
Failure probability estimation of complex offshore structures requires the modeling of the system behavior in terms of all uncertain parameters. This paper investigates the applicability...

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...

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...

Stochastic Evaluation of Landing Pier Construction
This paper discusses the process of determining the magnitude of external force such as wind and wave pressure exerted on marine structures under construction, and the learning curve of...

Correlated Non-Gaussian Models in Offshore Structural Reliability
Correlated non-Gaussian models of offshore loads and responses are developed. These require only correlation coefficients and either marginal distributions or moments. Simple estimates...

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...

Multi-Hazard Risk Assessment of an Offshore Structure
This paper develops and illustrates a methodology for multi-hazard modal risk assessment. The case study involves assessing risk to an offshore structure in a load environment consisting...

Reliability Analysis of Weldings Considering Defects
The welds generally represent the most critical part of large structural systems, i.e. offshore structures. Hence they affect significantly the structural reliability. A realistic model...

Adaptive Reliability-Based Inspection Strategies for Structures Subject to Fatigue
Metallic structures subject to substantial load-induced fatigue must be inspected from time to time and, possibly, repaired or even put out of service if the damage has reached critical...
