Use of Manned Submersibles to Investigate Slumps in Deep Water Gulf of Mexico
The Johnson-Sea-Link manned submersible was used to investigate surface slumps in the deep water Gulf of Mexico. High quality and specifically placed seafloor cores, video tapes, 35 mm...
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...
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...
Fiber Ropes for Ocean Engineering in the 21st Century
Recent advances in synthetic fiber ropes will greatly influence the practice of civil engineering in the oceans during the 21st Century. New fibers have moduli almost as high as steel...
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...
Use of X-Ray Computed Tomography in the Study of Marine Sediments
X-ray computed tomography (CT scanning) is primarily a medical imaging technique. When applied to marine sediments, it responds predominately to the spatial density distribution within...
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...
A Fourier Series Solution to Bottom Roughness Induced Stresses During Pipe Laying
Often during installation, a subsea pipeline must be laid along seabed portions with rough profiles. The pipeline is forced by the bottom irregularities to bridge across consecutive protuberances....
The Physiography and Engineering Constraints of the Continental Slope in the Northwestern Gulf of Mexico
The emplacement of structures on the seafloor has always been difficult but until recently, few knew just how difficult possible construction on the Northwestern Gulf of Mexico Continental...
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,...
