Arctic Marine Terminals -- Some Environmental And Engineering Considerations, Robert L. Mccollom Jr., William W. Moore

UMR Journal -- V. H. McNutt Colloquium Series

Studies are presently underway to determine the technical and economic feasibility of various Arctic marine transportation systems, including ice-breaker super-tankers and submarine tankers. An important consideration in these studies is the design and construction of marine terminal facilities which will be suited to the unique problems of the Arctic. Factors which will significantly affect the design of proposed marine terminals include:

1) bathymetric configuration of the continental shelf;
2) influence of moving pack ice on artificial structures, both at the air-water interface and along the bottom;
3) lateral and vertical variations in soil conditions, including residual permafrost, which might adversely …

Arctic Oil And The S.S. Manhattan, Russell H. Venn

UMR Journal -- V. H. McNutt Colloquium Series

The discovery of oil on Alaska’s North Slope in 1968 not only focused attention on that remote part of our world, it set the stage for one of the most exciting and significant scientific expeditions of our time—the voyage of the ice breaking tanker SS Manhattan through the Northwest Passage.

In the space available I would like to discuss with you that historic expedition, how it came to be, and comment on the results, as we see them.

Oil And Gas Reserves In The Siberian Shelf, A. J. Eardley

UMR Journal -- V. H. McNutt Colloquium Series

The Arctic region must be the world’s largest storehouse of liquid and gaseous hydrocarbons, and the vast Siberian region, both “on land” and “off shore” must be considered with envy by the free-world’s geologists for its oil and gas potential. It is here estimated that the off shore continental shelf of U.S.S.R. Siberia contains a reserve of 200 billion barrels of oil and 500 trillion cut. ft. of gas. These very approximate figures come from meager data obtained from the literature on oil and gas discoveries in the Siberian Arctic, the basin location of these discoveries, and the projection of …

The Role Of The Independent In Alaska's Mineral Development, D. L. Simasko

UMR Journal -- V. H. McNutt Colloquium Series

In 68 years of oil industry history in Alaska, the independent has already played a substantial role. Eighty-three independent oil companies or operators have participated in drilling 82 exploratory wells or stratigraphic tests. Their activities extended from the discovery of first commercial oil at Katalla in 1902, to the extension of the Prudhoe Bay field in 1970. The success ratio for wildcat wells in Alaska is considerably higher than “outside,” and fields have all been major in statute, thereby reducing the cost per barrel of finding oil.

The most immediate deterrent to the success of the independent in Alaska is …

Maintenance And Operation Of Facilities And Equipment In The Arctic, Charles C. Norris, Charles W. Kelley, Carroll C. Livingston

UMR Journal -- V. H. McNutt Colloquium Series

This has been but a short sketch of a few of the problems attached to living and working in the Arctic. Much has been learned about this remote and hostile area of the world; there is much more knowledge and experience required, as has been demonstrated by the controversy surrounding the routing and construction of the Trans-Alaska Pipeline. Man’s progress depends not only on means for his survival, but also on deep ecological considerations and solid engineering.--Conclusion.

The Alaska Business Community's View Of The Development Of Alaska, William H. Scott

UMR Journal -- V. H. McNutt Colloquium Series

America has discovered Alaska!! Or maybe that’s just the way it seems to us Alaskans. Even though Secretary of State Seward bought the Great Land (that’s what Alaska means in native tongue) more than a hundred years ago, very little of its nature has drifted down to the “Lower 48”. That is until the great oil reserves were discovered on the now-famous North Slope. Only then was the fact of Alaska’s mineral wealth translated into something other than very general admissions that Alaska was the natural resource storehouse of the United States. Now one would naturally conclude that the Prudhoe …

The U.S. Army's Experience In Handling Petroleum In An Arctic Environment, Frederic Johnson

UMR Journal -- V. H. McNutt Colloquium Series

This article pinpoints the various facets that the US Military experienced in Petroleum Operations in the Arctic environment Since the Military were the pioneers in Arctic operations, this experience could prove invaluable if and when the TAPS pipeline is constructed. The article deals primarily with various problems which beset the pipeliners during the initial construction phases and the peculiarities experienced during operations. A slightly different aspect will be experienced, however, when the Oil Industry moves relatively hot crude oil through the pipelines with TAPS since the Military moved only clean product.

The article addresses above ground pipeline operations, problems encountered …

The Future Of Anchorage, Claire O. Banks

So, in conclusion ... our Air Crossroads of the World contemplates its future, from a similar position as that of the ancient Greeks, or later the city of Rome... and much later ... England — the trade center of its time, between East and West — North and South. In any event, we are in the enviable position of being able to determine our future. Aside from the tremendous growth and build-up factors, we are unique because of our urbanity ... nowhere else are the advantages of modern day living offered to the extent they exist here, while at the …

State Regulatory Controls On Oil & Gas, Thomas R. Marshall Jr.

UMR Journal -- V. H. McNutt Colloquium Series

Alaska oil and gas regulatory matters are under the jurisdiction of a three-man Oil and Gas Conservation Committee, all of which are state employees.

In the last 10 years State water bottoms in Cook Inlet have been leased, explored and oil production amounting to about 200,000 barrels a day has been established. Cook Inlet is subject to very high tides and heavy ice flows. Five Salmon runs also occur in the Cook Inlet. The average daily production rate per well in the Cook Inlet area is nearly one hundred times the national average.

The Prudhoe Bay oil field discovered in …

Geologic Considerations And Solid Mineral Potential Of Alaska, A. E. Weissenborn

UMR Journal -- V. H. McNutt Colloquium Series

In marked contrast to Alaska’s petroleum industry, production from the State’s mining industry has declined drastically. Despite favorable geologic conditions, mineral exploration and development have been held back by inaccessibility, rugged terrain, severe climate, and scarcity and high cost of labor. Changing economic and political conditions, improved exploration techniques, and the ever increasing demand for minerals have again directed attention to Alaska’s mineral potential. Important discoveries in British Columbia and Yukon Territory have further stimulated exploration in Alaska. The probability that significant discoveries will result is high.

The titaniferous iron ores of southeastern Alaska probably will be brought into production …

Alaska's Possible Petroleum Provinces, George Gryc

UMR Journal -- V. H. McNutt Colloquium Series

Petroleum is the major Alaskan source of energy immediately available to the United States. Petroleum accounted for 89 percent or about $219 million of Alaska’s total mineral production in 1969 estimated at nearly $245 million.

Alaska’s first oil field was discovered at Katalla in 1902. About 154,000 barrels of oil were produced from 1902 to 1933. From 1945 through 1952, 45 shallow core tests and 36 test wells were drilled in and adjacent to Naval Petroleum Reserve No. 4 in northern Alaska. Oil deposits with possible reserves of 72 to 112 million barrels and gas deposits with possible reserves of …

Preface, Paul Dean Proctor, Robert E. Carlile

UMR Journal -- V. H. McNutt Colloquium Series

Because this university, formerly under the well known title of Missouri School of Mines and Metallurgy, has contributed so much to the nation’s and world’s mineral supplies through the work of its well trained graduates, it was considered appropriate that a major symposium be held during its Centennial Year on one of the last major mineral frontiers of the United States......Alaska.

Preliminary planning for the symposium on “Alaska, Its Mineral Potentials and Environmental Challenges” began in the fall of 1969. In January, 1970, Robert E. Carlile and Paul Dean Proctor visited Alaska to meet with some of the petroleum and …

Fastener Strength In Diaphragm Braced Members, Amir Simaan, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

SUMMARY In conjunction with research projects on diaphragm-braced members conducted at Cornell University, this investigation deals with the function of the fasteners in the braced system. In these systems, the diaphragm resists the lateral deflections of the braced members, in its plane, by virtue of its shear regidity (Qdr) and its shear strain capacity Yd (as a measure of strength). Considering the system in a slightly deformed shape, compatibility of displacements and forces between the diaphragm and the braced member at their connection locations, implies that the fasteners at these locations are subjected to the action of a system of …

Parameter For Comparing Anemometer Response, L. M. Fingerson

Symposia on Turbulence in Liquids

In comparing the theoretical performance of sensors, the term e_b/q (voltage change due to change In heat transfer) was found to be a fundamental sensor parameter. This was true for both sensitivity and frequency response in both constant current and constant temperature systems. Equations and data are presented for calculating this parameter for most wire and film sensors. Wedges, cones, and other non-cylindrical sensors have not been included because of their special problems at low frequencies due to conduction losses.

Internal cooling of the sensor is used for high temperature environments. Calculations show that the sensitivity at low …

An Attempt To Characterize The ‘Turbulence Burst Phenomena’ Using Digital Time Series Analysis, B. Johnson, R. Saylor

Symposia on Turbulence in Liquids

Several attempts to measure "periodicity" in the output signal of hot wires and hot films located in the viscous sublayer have been made in recent years. The usual method is to perform an autocorrelation on the signal and to interpret the strong peaks in the correlation function as indicative of the mean period of the "turbulence bursts" during a particular sampling interval.

The data analyzed for the presence of "turbulent bursts" were from the test of a 60-foot, 8-oared racing shell at the David Taylor Model Basin of the Naval Ship Research and Development Center. The shell was instrumented with …

The Analysis And Behavior Of Thin-Steel Hyperbolic Paraboloid Shells, Peter Gergely, P. V. Banavalkar, J. E. Parker

CCFSS Library (1939 - present)

An extensive experimental and analytical investigation of thin-steel hyperbolic paraboloid (hypar) structures was carried out to provide design information. As a result of this work, empirical data is provided regarding the behavior of such structures and computer programs are presented for the analysis of thin steel hypar structures. Hyperbolic paraboloid structures possess a unique combination of structural and architectural properties, some of them are the following 1) Due to the double curvature of the surface the internal stresses in the deck are generally low and the deflections are small. 2) Since a hyper surface can be generated by straight lines, …

In conjunction with the Technical Session, an …

Damping Capacity Of A Model Steel Structure, Dixon Rea, R. W. Clough, Jack G. Bouwkamp

CCFSS Library (1939 - present)

The damping capacities of seven model steel structures, each consisting of a heavy steel platform supported on four columns, have been determined from forced vibration tests. The vibrations were produced by an eccentric-mass vibration generator, and the amplitudes ranged from small displacements up to slightly greater than yield displacement. The tests were terminated at the higher amplitudes once fatigue cracks formed in any of the joint welds in the columns. For vibration amplitudes up to a critical amplitude slightly less than yield displacement, the damping factors of the structures were constant, independent of amplitude, and ranged between .15 and .25~ …

Analysis Of Light Gage Steel Shear Diaphragms, Albert R. Ammar, Arthur H. Nilson

CCFSS Library (1939 - present)

INTRODUCTION: It has long been recognized by structural engineers, that light gage steel cladding floor and roof decking systems have a considerable stiffening and strengthening effect on building frameworks. The beneficial contribution of these diaphragm systems is most pronounced when the structure as a whole is subjected to loads which result in an in-plane shear action of the cladding. This occurs, for example, when the rigidity of a floor or roof diaphragm acting as a membrane is utilized to transmit lateral forces to stiff end walls. Another example of diaphragm action is found in pitched roof portal sheds under vertical …

Laminar Heat Transfer For Small Prandtl Number Fluids Including Step Change In Wall Temperature, Shiny Ting

Masters Theses

"The object of this investigation is to provide a simple means of determining the heat transfer from a flat plate which has an unheated leading length x₀. The case of steady, two-dimensional, laminar flow of an incompressible fluid with a Prandtl number of less than one is considered. Since there exists an unheated length and the Prandtl number of the fluid is less than one, the thermal boundary layer intersects the flow boundary layer. Thus, the solution of the problem divides into two regions. In this study, the problem is solved analytically by employing the energy integral equation. The temperature …

A Measurement Of Complex Viscosity With Large Amplitudes, Kuo-Shein Shen

Doctoral Dissertations

"In order to study the viscoelastic properties of polymer solutions and greases, a dynamic apparatus was built for making measurements of complex viscosity. Characteristic impedance was measured by a force transducer, an accelerometer and a phase meter. Large amplitudes to 0.5 inch can be obtained with this apparatus. The largest amplitude used was 1.27 x10⁻¹ cm. The frequency range was 30 Hz - 1500Hz. The lowest dynamic viscosity to be measured was 0.5 poise. In order to determine the capabilities of the instrument, complex viscosities of polymer solutions and greases were measured. The polymer solutions studied were polyisobutylene (PIB) L-80, …

On-Line Economic Optimization Of A Chemical Reactor, Jesse Daniel Bennett

Doctoral Dissertations

"An economic optimizing control system for a continuous flow stirred tank chemical reactor is designed, simulated, and installed on a pilot scale reactor. The control scheme utilizes a reaction and reactor model to predict on-line the economic optimum of a reactant concentration. In this manner the control system manipulates the reactant flow rate to maintain the optimum concentration during changes in reaction-reactor parameters with time. Typical parameter changes include the decay of reaction catalyst activity. The optimizing controller will function in conjunction with various operating policies including control to maintain a specified production rate"--Abstract, page ii.

Deriving Dc Machine Torque By The Principle Of Virtual Work, George Mcpherson

Electrical and Computer Engineering Faculty Research & Creative Works

The purpose of this paper is to fill a gap which exists in the "textbook" theory of dc machines. The paper shows that the usual expression for dc machine torque can be obtained from the direct application of the principle of virtual work to the machine, making the traditional assumptions. The method provides additional benefits in that it demonstrates the reluctance torque which results from the saliency of the field structure and shows that compensating windings have no effect on the torque under the assumed linear conditions.
