Abstract Wells plug & abandonment was carried out in a deepwater field (Field C) offshore West Africa. There were 15 deepwater subsea wells in this field. Thirteen of the wells were completed with Open Water Vertical Xmas Tree (OXT) while remaining two were completed with Enhanced Vertical Xmas Tree (EVXT). In the wells with Open Water Vertical Xmas Tree (OXT), the upper completion tubing and hanger were ran together with the Xmas Tree in a single run. This posed challenges to Operator in retrieving the Xmas Tree. This paper will discuss the novel approach used by Operator in the OXT retrieval. Due to the design of OXT which was different from most of the vertical Xmas Trees (XT) in the world, there were a few challenges in the process of XTs retrieval. If the XTs and upper completion tubing were retrieved in reversal of the way it was completed, it will exposed the well to prolonged duration of single barrier until a BOP can be latched on for subsequent activities. On top of that, the Original Equipment Manufacturer's Completion Workover Riser (CWOR) system and Support Landing Structure (SLS) was not available in full package to be utilized in this project. Furthermore, there were constraints on the rig moonpool space, handling of OXT on surface and clashes between the rig's BOP and existing subsea structures. In managing the risk of well exposure to single proven and monitored barrier during the process of OXT retrieval, Operator has evaluated a few options and came out with a novel approach in the OXT retrieval which managed to minimize exposure time and reduce risk in operations. In contrary to the original principle of well completion here, after a barrier was established in the well, the OXTs was retrieved separately from the upper completion tubing to allow rig BOP to be latched onto wellhead in shortest possible time. To achieve this objective, operations was planned to be carried out on a dual activity derrick rig. Meanwhile, a non-OEM rental CWOR system was used together with Tree Running Tool from the OEM CWOR system to access the wells for intervention work and subsequently retrieve the OXTs. By doing this, the combined CWOR stack exceeded the height limitation at the rig's moonpool. Some modifications were carried out to allow the operations to happen. A novel approach was also used to handle the OXT on surface without the OEM Support Landing Structure - which simplified the operations and reduced HSE risks. Solution was also put into place to enable latching of the rig BOP onto wellheads on Drill Centre although there were risk of clashing initially.

Abstract Jesus films remain popular in missionary work, yet little is known about how they communicate. Working with viewers in Benin, West Africa, I observed that they watch films as an embodied practice that goes beyond the explanatory power of meaning-based communication models. For them, the filmic portrayal of Jesus is not an image or representation; it rather reveals Christ’s presence in a veracious and immediate way. Consequently, people experience the actor as if he were Jesus, who sometimes interacts with them in dreams. I argue that current anthropological theories are inadequate when trying to account for this. By shifting the focus from meaning to presence, and by introducing the notion of the ‘onton,’ I propose the novel approach of ‘ontonic semiotics’ that accounts for how people make sense of, and interact with, the world. This approach highlights the need to give more attention to how Jesus appears to global audiences.

Abstract This study is about heroism in the novel The Jungle Book by Rudyard Kipling. There are three points of discussion under this title: giving protection, defending rights and gratitude. Defending rights is associated with heroic deeds. A hero is a random citizen that rises to an occasion and performs an action of superhero proportions. Gratitude implies thankfulness or an appreciation of benefits conferred together with a desire, when practicable, to return those benefits. Defending rights is tied to human rights which are universally applicable to one and all. These are the significant components of heroism. One of the relevant and outstanding modern theories of heroism applied here is proposed by Gibbon (2009) stating that hero is just an average man who fights to solve a common problem in today’s society. The study is conducted with Descriptive Qualitative Method proposed by Haughman (2009) in which he states that Qualitative research is a form of social inquiry that focuses on the way people interpret and make sense of their experiences and the world in which they live. Kipling leads children down the jungle path into adventures beyond their day to day imagining and along the way he shows the value of ‘doing for yourself', of 'learning who to trust'. The result shows that heroism is highlighted through the major characters and the conclusive points are some of the significant characters such as Mowgli, Father Wolf, Mother Wolf, Hathi, and Bagheera have done heroic deeds. Their heroism is presented in the forms of giving protection, defending rights and gratitude. Keywords: heroism, human rights, gratitude

In the past decades, English learning has received lots of attention all over the world, especially for those who are not native English speakers. Various English learning and testing systems have been developed on the Internet. Nevertheless, most existing English testing systems represent the learning status of a student by assigning that student with a score or grade. This approach makes the student aware of his/her learning status through the score or grade, but the student might be unable to improve his/her learning status without further guidance. In this paper, an intelligent English tense learning and diagnosticsystem is proposed, which is able to identify studentlearning problems on English verb tenses and to provide personalized learning suggestions in accordance with eachstudent’s learning portfolio. Experimental results on hundreds of college students have depicted the superiority of the novel approach.

Owen Clayton, "London Eyes: William Dean Howells and the Shift to Instant Photography"(pp. 374––394) Toward the end of the nineteenth century, one of William Dean Howells's many avid readers, finally meeting him in the flesh, expressed surprise that the famed writer was not dead. Although he had not actually departed from the world, it was true that by this time the venerable "Dean"was at a low ebb. While younger authors were taking the novel in directions about which he was, at the least, ambivalent, Howells was aware that his own best work was behind him. Yet, throughout his career, he maintained a desire to test different literary approaches. In England in 1904, Howells tested a conceit that would allow him to keep pace with the literary movements of the day. This consisted of an extended photographic metaphor: an association of himself with the Kodak camera. He used this figuration to move beyond the philosophical foundations of his previous work. Criticism has largely overlooked this endeavor, which Howells buried away in the somewhat obscure travelogue London Films (1905). This essay shows how London Films used its photographic metaphor to question positivistic observational assumptions, the way in which this was a response to William James's Essays in Radical Empiricism (1912), and, finally, why Howells ultimately went back on his attempt to create a Kodak school in fiction.

This paper focuses on the presentation of women oppression and emancipation in Nawal El Saadawi’s novel, Woman at Point Zero. The novel is specifically a call and an appeal to the women in her Egyptian society and the world at large on the need to revisit their activities and contribution toward the oppression, suppression, molestation, and brutality of their fellow women. Nawal El Saadawi presents with unique clarity, the unpleasant experience women are subjected to in her male-dominated society (Egypt). The novel aesthetically captures the oppression, sexual harassment, domestic aggression, and intimidation that the Egyptian women are subjected to in her patriarchal social milieu. Through a Masculinist study of the text, this paper not only submits that women create sa conducive atmosphere for the unhappiness of their own kinds but also subverts the author’s proposition of the way forward for the Egyptian women who are disenchanted under the atmosphere that is besieged with unfair treatment of the women. This essay unambiguously argues that El Saadawi’s understanding of women emancipation from the persistent violence on the women is outrageously momentary and unsatisfactory. Indeed, the novel has succeeded in subverting the stereotypical representation of the women as weak, passive, and physically helpless yet, the cherished long-lasting emancipation expected from her oppressed women could not be fully achieved. The novelist portrays a resilient and revolutionary heroine whose understanding of women liberation leaves every reader disconcerted. The paper examines the oppression that the heroine, Firdaus suffers from men and her fellow women and how she eventually achieved a momentary emancipation.

When the first Stena V-MAX vessel, the Stena Vision, entered the Delaware River on her maiden voyage in the summer of 2001 (as this symposium [MEETS01] was being held in Washington) she marked the realization of a project that started almost five years earlier. In October 1996 the 1975-built Stena Constellation made the same voyage up to Philadelphia as the first VLCC ever to dock at the Fort Mifflin terminal. The operation involved a new scenario compared with the normal open-water VLCC trading, and all the parties involved contributed to assess risks and establish safe procedures for the different phases. As the operation developed, so did ideas on an improved ship design which would be better suited to do the job on a year-round basis. This led to a new type of VLCC with wide beam and shallow draft, the V-MAX. Apart from carrying a significantly larger amount of cargo, the V-MAX is also uniquely equipped to cope with the challenges and hazards of the river passage, making oil transportation to Philadelphia both safer and more efficient compared with her predecessors. In the world of today we avoid flying passengers in single-engine aircraft. Similarly we should strive to avoid a situation where a single technical failure on an oil tanker could lead to an ecological disaster. The twin propellers and rudders are the most visible features, which, apart from redundancy against single failures, give the wide hull superior maneuvering characteristics. These and numerous other technical aspects and operational considerations make the V-MAX represent not only a new ship but also a complete concept for safe oil transportation in narrow waters. This paper outlines the background and evolution of the V-MAX concept and describes the specific features which contribute to effectively reduce risk when operating in narrow and heavily trafficked areas.

Abstract This essay revisits the question of the fictional person, largely by way of Proust’s claim that the novel offers us nonexistent persons the better to espouse vision through other eyes: knowledge of the world as experienced by another consciousness. If the New Critical stricture against taking fictional characters as real beings—something other than writing on a page—is correct, it does not account for the way in which we imagine, make use of, and interact with the minds of literary characters. Yet Proust’s understanding of the fictional being cohabits with the inevitable death of real persons. As in Henry James, for instance, character may border on nothingness, on illusion—yet it appears an inevitable illusion, one that we need in order to make sense of our lives.

SUMMARYIn this paper, we puzzle the way that sovereignty has been a sketchily present dynamic in conservation discourses. In the case of the world's many island communities whose colonial histories extend into the present in virtually every domain, silences around sovereignty in conservation contexts are particularly notable for the way they suggest the enduring domination of local communities by distant metropoles. Here, we provide a review of several critical issues in Pacific Islands contexts – biosecurity, food security, intellectual and material property rights and protected areas – that highlight the importance of conceptualizing sovereignty beyond the state to better enhance conservation outcomes. The novel approach we take in regard to these problems is to encourage conservation practitioners to more deeply engage with the ‘ecological futures’ that indigenous and local island communities are weaving in a period of active (re)articulations of sovereignty in conception, legal constitution and everyday engagements with island environments.

Ovid’s myth of the Cretan labyrinth, constructed by Daedalus to hide the Minotaur, the monster that is a result of Pasiphae’s lust, and Dante’s labyrinth of Hell, in The Inferno, are literary allusions that conjure images of imprisonment and moral dilemma. In this paper, I explore the metaphor of the labyrinth in The Year of Living Dangerously (YLD) and the way in which Koch integrates this metaphor with Christian, Hindu and Buddhist myths so as to engage with the cultural divide that continues to influence Christian and non-Christian worldviews. The labyrinth metaphor emerges through the imagery of the novel which focuses on caves, shadows, circuitous paths, entrapment, and moral choices. In the novel, the metaphor of the labyrinth is conveyed through the underworld imagery of Indonesian society and through the Wayang Bar, the citadel of the journalists trapped in a world of political intrigue and of good and evil. Metaphorically evoking the medieval concept of the world as a perilous maze, Koch uses the labyrinth as a way of imaging the search for the sacred in contemporary society.
