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)...
Experimental Research on Groyne Stability Under Very Oblique Wave Action
Most of the experimental research concerning the stability of coastal structures is focused on normal wave incidence. However, many of these structures are subject to waves which run predominantly...
Application of Fracture Mechanics Methodology to Assessment of Weld Defects in Offshore Platforms
This paper demonstrates an application of both deterministic and probabilistic fracture mechanics methods to assess weld defects in an offshore platform. The results of the assessment...
Simplified Methods for Assessment of the Structural Integrity of Existing Steel Jacket Platforms in the Gulf of Mexico
This paper presents the results of research to define a practical procedure for assessment of the structural integrity of existing steel jacket platforms in the Gulf of Mexico. An overview...
Review of API Guidelines for Pipe Piles in Sand
Most offshore structures are supported using steel pipe piles which are designed in accord with API Recommended Practice 2A. The guidelines for analysis of axial capacity of steel pipe...
Homopolar Pulse Butt Welding of API 5L Line Pipe
Homopolar pulse welding (HPW) is a welding process that is being investigated as a means to rapidly join API line pipe, having particularly great potential for application in deepwater...
Effects of Freezing on Impact Properties of RTM Composites, and Their Applications in Offshore Structures
Resin transfer molding is rapidly being acknowledged as the process with potential to create perhaps the purest form of a composite material as representative of the concept of `material-by-design.'...
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...
Dynamic Design of Deepwater Bottom-Founded Towers
This paper traces the development of dynamic design techniques for deepwater bottom-founded towers by the following: the classification of bottom-founded towers as either `stiff' or `compliant';...
Equivalent Statistical Quadratization of Nonlinear Hydrodynamic Loads on TLPs
In this paper, a new method is proposed for the expansion of nonlinear drag forces expressed in terms of multivariate Hermite polynomials correct up to the second-order. The drag force...
Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
Response Statistics of Tension Leg Platforms Under Wind Loads
This paper presents the direct integration method and Kac-Siegert technique to solve the first four cumulants in the general quadratic systems, and proposes the splitting technique to...
Advanced Structures in Very Deep Water
Factors which are largely economic will lead to the requirement to design and deploy small numbers of large platforms and large numbers of small platforms in water depths of up to 4 km...
Composites for Offshore Applications: A Multidisciplinary Education Program for the Marine Industry
Composites are increasingly being considered for offshore and other marine structural applications. Polymeric matrix composites reinforced with glass, carbon, and aramids offer substantial...
Internationalization of Engineering Professions
The most salient features impacting the development of our deepwater frontier areas are considered. The areas of higher potential for deepwater reserves are identified. The integrated...
Old Problems and New Challenges in Marine Geotechnical Engineering
The discipline of marine geotechnical engineering originated nearly five decades ago, primarily as a result of the offshore oil and gas industry. As this industry moved into deeper waters,...
Piles Under Dynamic Loads
This proceedings,
Wastewater under Home Plate
A short, highly sloped piping system and peak flows at the start and end of the day were causing the wastewater treatment plant in Daly City, Calif., to frequently exceed its permit for...
Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
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...
