Schematization of Hydrodynamic Forces Acting on Jack-up Legs and Morison Coefficients for Jack-up Legs
No full textThe first report is about: A jack-up rig is a mobile offshore platform. Basically, it is a self-elevating pontoon, which can be supported by retractable legs resting on the sea bed. Recently, it is proposed to use these platforms for production of marginal fields, what implies a longer term use. Furthermore, there are plans to use such platforms in deeper water. For design calculations and for checking whether the rig can be used on a new location, it is necessary to know the horizontal wave forces acting on the leg. Since the jack-up leg consists of many bars, direct wave force calculations are time consuming. Therefore, a schematization is required. The second report is about: The calculated and measured drag and inertia coefficients for a complete jack-up leg bay at high Reynolds numbers (0.5-1.2 * 10e).Offshore EngineeringHydraulic EngineeringCivil Engineering and Geoscience
Integral soil-jack-up modelling - Modelling site-specific jack-up response and performing safety assessment
No full textDue to the growing offshore wind energy market and the increasing interest of the oil and gas industry, there is a steadily increasing demand for the use of jack-ups all over the world. Particularly, the number of wind turbine installation vessels has increased from 2 in 2005 to 40 currently, with a yearly growth expectation of 30% till 2020. Accident statistics from the Worldwide Offshore Accident Databank show the necessity for safer designs of jack-ups and other mobile offshore platforms. A better understanding of the soil-structure interaction and an accurate determination of the limiting loading conditions can contribute to the reduction of this failure rate. Due to the growing demand of jack-ups and the necessity for safer designs, an integral parametric model is developed to study the jack-up response comprehensively. The jack-up model combines a force resultant soil-spudcan interaction model with a structural model of the jack-up, both with 6 degrees of freedom. An illustration of the jack-up model is presented in Figure i. Environmental loads (wind-, wave- and current loads) are applied to the structural model to determine the load distribution in the jack-up structure and among the spudcans. Inputs for the jack-up model are structural properties, soil-spudcan interaction parameters, environmental conditions and preload forces. As output, the integral jack-up model provides hull and spudcan displacements for 6 degrees of freedom, internal forces and internal moments at the leg-hull connection and forces and moments applied on the soil. Furthermore, the model checks if the spudcan loads, applied to the soil, stay within the yield surface, which means that the soil response is linear elastic and the elastic soil model is valid. To assess the value of the developed integral soil-jack-up model including the chosen soil-spudcan interaction model, a comparison is made with the jack-up model combined with two other widely used soil-spudcan interaction models: a pinned soil-spudcan connection and a rotational spring connection. The comparison showed that the implemented force resultant soil-spudcan interaction model provides highly accurate results, in contradiction to the pinned and rotational spring connection. The rotational stiffness, included in the soil-spudcan interaction model, reduces the bending moment in the jack-up legs significantly. Use of the pinned soil-spudcan interaction model overestimates the bending moment in the leg. The rotational spring however, underestimates the leg bending moment. The developed jack-up model shows clearly a force distribution among the legs by means of the hull, which has a significant influence on the spudcan loads. Therefore, it can be concluded that an integral soil-jack-up model is preferred over a single leg model. A parametric sensitivity study on the soil stiffness factors showed 2 important facts. First, the rotational soil stiffness (k_r ) is the most important soil stiffness factor, since it has the greatest influence on the system response and load distribution among the legs, regardless of the applied load or reviewed spudcan load. Second, the response of the system approaches an asymptote for stiffness factors around the upper boundary values. For variation in the stiffness factor values around the lower boundary values, the system response appears to be much more sensitive. A parametric sensitivity study on structural properties of the jack-up showed the following. Increasing the spudcan radius has 3 major effects: it decreases the spudcan penetration, increases the spudcan displacements and decreases the mobilization of the rotational spudcan capacity. Adding extra legs to the jack-up results also decreases spudcan penetration and increases hull- and spudcan displacements. However, the torsional displacement and torsional moment of the hull and spudcans is reduced when extra legs are added to the jack-up. For a jack-up with one enlarged leg, the horizontal hull displacement is reduced but the torsional rotation is increased significantly. Enlargement of one leg has also a large effect on the torsional displacement of the spudcans. The enlarged leg attracts more loads than the normal legs. Due to its increased diameter, the total jack-up attracts more environmental loads.Bottom founded structuresOffshore EngineeringCivil Engineering and Geoscience
From the ‘freedom of the streets’: a biographical study of culture and social change in the life and work of writer Jack Common (1903-1968)
Get PDFThe author assesses the life and work of the Newcastle upon Tyne born writer Jack Common in the light of the massive social, economic and cultural changes which have affected the North East of England and wider society through the period of Common's life and afterwards. He seeks to point out the relevance of Common to the present day in terms of his ideas about class, community and the individual and in the light of Common's sense of rebelliousness influenced by a process of grass-roots education and self-improvement. In addition, he draws upon his own extensive experience in community arts and education, looking, in particular, at the work he and others have carried out on Common over the last thirty years and assessing its value in the light of recent political changes. The author draws together the range of biographical and literary criticism carried out by a range of individuals over this period of time and brings into print hitherto unpublished material about Common's life and work by interviewing family members and associates, exploring the Common Archive at Newcastle University and other largely ignored sources, and studying Common's significant association with George Orwell in great detail. Through all of this, he seeks to argue that Common's life and ideas remain worthy of close attention in the present day

A note on the map expansion of Jack polynomials
Get PDFIn a recent work, Maciej Do\l{}e\k{}ga and the author have given a formula of
the expansion of the Jack polynomial in the power-sum
basis as a non-orientability generating series of bipartite maps whose edges
are decorated with the boxes of the partition .
We conjecture here a variant of this expansion in which we restrict the sum
on maps whose edges are injectively decorated by the boxes of . We
prove this conjecture for Jack polynomials indexed by 2-column partitions. The
proof uses a mix of combinatorial methods and differential operator
computations.Comment: 20 pages, 2 figure
Motion and mobility in the realist novels of Philip K Dick
No full textThis essay explores the ways that ideas of motion and mobility support readings of Philip K Dick's early novels that take full account of the changing geographical context. They are set during a period of rapid suburban expansion, the building of the interstate and the spread of automobility through car ownership, and their characters frequently exist in a state between continuity through conformity and the potential for change. The open ended forms of the novels reflect a world around Dick that was still under construction, and where alternative realities can be glimpsed between incomplete materialities
Design and testing of a thick-film dual-modality sensor for composition measurements in heterogeneous mixtures
No full textThe current paper focuses on design and laboratory evaluation of a dual-modality sensor, developed for the needs of oil and gas extraction industry to measure the composition of heterogeneous mixtures in harsh conditions. The sensor combines ultrasonic and electrical measurement techniques, which are non-destructive, rapid and can potentially provide an on-line industrial measurement. Such a ‘dual-modality’ measurement could potentially be reliable in a wider range of process conditions. A distinct feature of the sensors presented here is their construction, which makes use of the thick-film technology, enabling the construction of multi-layered structures of both conductive and non-conductive layers, some of which may exhibit piezoelectric properties for ultrasonic measurement purposes. These are later fired on a ceramic substrate to provide rugged sensors, capable of working in aggressive industrial environments. Laboratory experiments to investigate the feasibility of the dual-modality sensors were conducted and some comparisons with the theoretical predictions are presented
Religion, myth, magic, and folklore in Rabbit, Run and Song of Solomon
No full textJohn Updike in Rabbit, Run and Toni Morrison in Song of Solomon extensively use religion and mythology as themes throughout their works, but in strikingly different ways. Updike was a practicing Christian and student of Christian theology all of his life. Two of his greatest influences were neo-Orthodox theologian Karl Barth and philosopher Soren Kierkegaard, illustrated throughout the novel in the portrayals of the protagonist Harry “Rabbit” Angstrom, and Reverend Fritz Kruppenbach, and contrasted sharply to the Reverend Jack Eccles. Updike uses mythology to contrast with the religious themes and overtones of the story. Toni Morrison in Song of Solomon also uses Christian theology, but in a far subtler and different way. Morrison uses the influence of the black church in America on her character portrayals, particularly their names. But Morrison‟s real focus is the African origins of the black church in America, as well as the magic and folklore of Africa.M.A.L.S.Includes bibliographical referencesby Rachel K. Bogati
