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...
Pipeline Storm Behavior on Clay Soils
A series of transverse wave loading tests was conducted on a specially mounted section of pipe in a sediment-filled tank, to investigate the stability of unburied submarine pipelines under...
Upper Bound Limit Analysis of Deep Skirt Structures' Foundations
A solution to the problem of determining the bearing capacity of an embedded footing (foundation) subjected to arbitrary loading is being presented herein. It is primarily intended for...
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...
Corrosion Fatigue of Deepwater Offshore Materials
Evaluation of the fatigue life of offshore structures operating in depths of up to 10,000 feet (3,048 m) requires knowledge of the combined effect of axial and hydrostatic loading on the...
Skin Friction Distrtibutions on Piles in Sand
Presented in this paper are early results from an analytical investigation of the performance of a closed-ended pipe pile under monotonic axial loading in dense sand. The study was performed...
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...
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...
Piles Under Dynamic Loads
This proceedings,
Predicting Sediment Loads
Many reservoirs in the U.S. and internationally have experienced unforeseen storage loss when sediment loads exceed those originally predicted during the design stage. This often results...
Safety Factors, Loads, and Impact
The loads given in this chapter are intended for general guidance only (including wind, ice, stream flow, etc.). Maximum deflections and rotations may likewise vary with national codes....
Stability of Cable-Stayed Brides
This chapter deals only with stability under static loadings. For aerodynamic stabilities and stability of structure under seismic loading, see the appropriate chapters. Both the towers...
Dynamic Wind Loads
This chapter is concerned with the motions of cable stayed bridges that arise as a result of wind action. The aerodynamic phenomena that must be considered are vortex shedding, torsional...
The Effect of Loading Rate on the Bending Strength of Alluvium Reinforced Ice
Traditional building materials are often less than ideal for construction in remote Arctic locations. Their mechanical properties may be degraded in extreme cold, and costs associated...
A Mechanistic Approach to Pavement Design for Nome Airport
The analysis of performance and design of the pavement structure for the North-South runway at Nome Airport is based on the mechanistic approach. In the mechanistic approach, calculated...
