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...
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....
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,...
Settling Down Easy
In order to more fully participate in the international and Asian Pacific aviation network, it was decided to establish a highly efficient 24-hour a day operation at the New Kansai International...
Civil Engineering in the Oceans V
This proceedings is a collection of technical papers presented at Civil Engineering in the Oceans V (CEO V) specialty conference held at College Station, Texas on November 2-5, 1992. Initiated...
Laboratory Observations of Macroscopic Failure Modes in Freshwater Ice
A review is presented of tests performed in the laboratory by several investigators on indentation in freshwater ice. A number of the observed failure modes are discussed. From the results,...
Some Questions on Fracture Mechanics of Ice and Ice Covers
Investigation of natural processes of deformation and fracture of ice covers, and processes of its interaction with icebreaker or ice-resistant structures requires as a rule considerations...
Effective Pressures Measured During Indentation Tests in Freshwater Ice
Indentation tests were conducted by pushing flat, vertical indentors of two different widths (50 and 100 mm) against the edges of floating, freshwater ice at different velocities (0.6-150...
Application of Ice/Structure Interaction Concepts to a Real Time Ice Risk Assessment Computer Model
The successful and safe operation of an Arctic offshore exploration structure greatly depends on the implementation of alerts procedures. In order to assess alerts levels, a computer model...
Wang's Equation for Ice Forces From a Pressure Ridge
Yung-shih (Tony) Wang has presented an equation for the breaking loads from a multiyear pressure ridge on a conical structure. The three distances that define the position of the plastic...
Dry Drilling and Coring Development for Unsaturated Zone Studies
Two areas of major difficulty associated with characterization of any unsaturated zone are the conventional drilling and coring processes used to acquire the samples. These processes are...
Hydrodynamics of Deepwater Tension Leg Platforms
A model is presented for investigating the overall quasi-static behavior of tethers, the anchoring elements for a Tension Leg Platform, TLP. Effects of tether weight and curvature, and...
Interaction Between Waves and a Floating Body with Tension Legs
A boundary element method has been solved to the coupling problem of a two-dimensional tension leg platform interacting with a monochromatic wave train. In the boundary element calculation,...
Wave Loading Linearization for Offshore Structures
The linearization of Morison-type wave loading is to replace u|u| by cu, where u is a zero mean, stationary Gaussian random process and c is a constant. In the present study an optimal...
Experimental and Numerical Chaos in Continuous Systems: Two Case Studies
Motivated by recent numerical investigations according to which certain types of deep-water compliant offshore structures may experience undesirable chaotic motions, two types of experimental...
Dynamic Testing to Predict Static Performance of Drilled Shafts Results of FHWA Research
The paper describes the preliminary results of recent research sponsored by the FHWA on predicting by relatively economical dynamic methods, the static capacity and performance of drilled...
Induced Subsidence: Environmental and Legal Implications
Subsidence of coastal areas can be induced by withdrawal of fluids from shallow, unconsolidated horizons beneath the shore zone. In southern California, Huntington Beach, Torrance/Redondo...
How Has the Joint Review Process Evolved?
The Joint Review Panel (JRP) process in California was established for offshore oil and gas-related coastal development projects to avoid duplication of effort among various permitting...
