    Predictive Maintenance of Critical Equipment for Liquefied Natural Gas Liquefaction Process Meeting global energy demand is a massive challenge, especially with the quest of more affinity towards sustainable and cleaner energy. Natural gas is viewed as a bridge fuel to a renewable energy. LNG as a processed form of natural gas is the fastest growing and cleanest form of fossil fuel. Recently, the unprecedented increased in LNG demand, pushes its exploration and processing into offshore as Floating LNG (FLNG). The offshore topsides gas processes and liquefaction has been identified as one of the great challenges of FLNG. Maintaining topside liquefaction process asset such as gas turbine is critical to profitability and reliability, availability of the process facilities. With the setbacks of widely used reactive and preventive time-based maintenances approaches, to meet the optimal reliability and availability requirements of oil and gas operators, this thesis presents a framework driven by AI-based learning approaches for predictive maintenance. The framework is aimed at leveraging the value of condition-based maintenance to minimises the failures and downtimes of critical FLNG equipment (Aeroderivative gas turbine). In this study, gas turbine thermodynamics were introduced, as well as some factors affecting gas turbine modelling. Some important considerations whilst modelling gas turbine system such as modelling objectives, modelling methods, as well as approaches in modelling gas turbines were investigated. These give basis and mathematical background to develop a gas turbine simulated model. The behaviour of simple cycle HDGT was simulated using thermodynamic laws and operational data based on Rowen model. Simulink model is created using experimental data based on Rowen’s model, which is aimed at exploring transient behaviour of an industrial gas turbine. The results show the capability of Simulink model in capture nonlinear dynamics of the gas turbine system, although constraint to be applied for further condition monitoring studies, due to lack of some suitable relevant correlated features required by the model. AI-based models were found to perform well in predicting gas turbines failures. These capabilities were investigated by this thesis and validated using an experimental data obtained from gas turbine engine facility. The dynamic behaviours gas turbines changes when exposed to different varieties of fuel. A diagnostics-based AI models were developed to diagnose different gas turbine engine’s failures associated with exposure to various types of fuels. The capabilities of Principal Component Analysis (PCA) technique have been harnessed to reduce the dimensionality of the dataset and extract good features for the diagnostics model development. Signal processing-based (time-domain, frequency domain, time-frequency domain) techniques have also been used as feature extraction tools, and significantly added more correlations to the dataset and influences the prediction results obtained. Signal processing played a vital role in extracting good features for the diagnostic models when compared PCA. The overall results obtained from both PCA, and signal processing-based models demonstrated the capabilities of neural network-based models in predicting gas turbine’s failures. Further, deep learning-based LSTM model have been developed, which extract features from the time series dataset directly, and hence does not require any feature extraction tool. The LSTM model achieved the highest performance and prediction accuracy, compared to both PCA-based and signal processing-based the models. In summary, it is concluded from this thesis that despite some challenges related to gas turbines Simulink Model for not being integrated fully for gas turbine condition monitoring studies, yet data-driven models have proven strong potentials and excellent performances on gas turbine’s CBM diagnostics. The models developed in this thesis can be used for design and manufacturing purposes on gas turbines applied to FLNG, especially on condition monitoring and fault detection of gas turbines. The result obtained would provide valuable understanding and helpful guidance for researchers and practitioners to implement robust predictive maintenance models that will enhance the reliability and availability of FLNG critical equipment.Petroleum Technology Development Funds (PTDF) Nigeri

    It had been more than two decades passing by aftermath the devastating Asia’s Financial Crisis in 1997, subsequently followed by Suharto’s step down from his presidential throne which he occupied for more than three decades. The financial turmoil turned to a political disaster furthermore has led to massive looting that severely impacted Indonesians of Chinese descendant, including unresolved mystery of the most atrocious sexual violation against women and covert killings of students and democracy activists in this country. Since then, precisely aftermath May 1998, which publicly known as “Reformasi”1, Indonesia underwent political reform that eventually corresponded positively to its macroeconomic growth. Twenty years later, in 2018, Indonesia captured worldwide attention because it has successfully hosted two internationally renowned events, namely the Asian Games 2018 – the most prestigious sport events in Asia – conducted in Jakarta and Palembang; and the IMF/World Bank Annual Meeting 2018 in Bali. Particularly in the IMF/World Bank Annual Meeting, this event has significantly elevated Indonesia’s credibility and international prestige in the global economic powerplay as one of the nations with promising growth and openness. However, the narrative about poverty and inequality, including increasing racial tension, religious conservatism, and sexual violation against women are superseded by friendly climate for foreign investment and eventually excessive glorification of the nation’s economic growth. By portraying the image of promising new economic power, as rhetorically promised by President Joko Widodo during his presidential terms, Indonesia has swept the growing inequality in this highly stratified society that historically compounded with religious and racial tension under the carpet of digital economy.Arte y Humanidade

    Platform protocol place: a practice-based study of critical media art practice (2007-2020)

    Get PDF
    This practice-based research project focuses on critical media art practices in contemporary digital culture. The theoretical framework employed in this inquiry draws from the work of the Frankfurt School, in particular Theodor Adorno and Max Horkheimer’s The Culture Industry: Enlightenment as Mass Deception. Using Adorno & Horkheimer’s thesis as a theoretical guide, this research project formulates the concept of the digital culture industry - a concept that refers to the contemporary era of networked capitalism, an era defined by the unprecedented extraction, accumulation and manipulation of data and the material and digital infrastructures that facilitate it. This concept is used as a framing mechanism that articulates certain techno-political concerns within networked capitalism and responds to them through practice. The second concept formulated within this research project is Platform Protocol Place. The function of this second concept is to frame and outline the body of practice-based work developed in this study. It is also used to make complex technological issues accessible and to communicate these issues through public exhibition and within this written thesis. The final concept developed in this research project is tactical media archaeology. This concept describes the techniques and approaches employed in the development of the body of practice-based work that are the central focus of this research project. This approach is a synthesis of two subfields of media art practice and theory, tactical media and media archaeology. Through practice, tactical media archaeology critiques the geopolitical machinations and systems beneath the networked devices and interfaces of the digital culture industry

    B/order work: recomposing relations in the seamful carescapes of health and social care integration in Scotland

    Get PDF
    As people, ageing and living with disabilities, struggle with how care is enacted through their lives, integrated care has gained policy purchase in many places, especially in the United Kingdom. Accordingly, there have been various (re)forms of care configurations instigated, in particular, promoting partnership and service redesign. Despite integrations apparent popularity, its contribution to improved service delivery and outcomes for people has been questioned, exposing ongoing uncertainties about what it entails and its associated benefits. Nonetheless, over decades, a remarkably consistent approach to integrated care has advanced collaboration as a solution. Equally, any (re)configurations emerge through wider infrastructures of care, in what might be regarded as dis-integrated care, as complex carescapes attempt to hold and aporias remain. In 2014, the Scottish Public Bodies (Joint Working) (Scotland) Act mandated Health and Social Care Integration (HSCI), as a means to mend fraying carescapes; a flagship policy epitomising public service reform in Scotland, in which normative aspirations of collaboration are central. What then are the accomplishments of this ambitious legislation? From the vantage point of 2021, HSCI has been assessed as slow and insubstantial, but this is not the complete picture. Narratives about failing to meet expectations obscure more complicated histories of cooperation and discord, successes and failures, and unintended consequences. Yet given collaborative ubiquity, if partnerships are contested how then are they practiced? To answer this question, I embarked on an interorganisational ethnography of the enactment of a Health and Social Care Partnership (HSCP), which went ‘live’ on April 1st, 2016; in a place I call ‘Kintra’. I interrogate what happened when several managers (from the NHS and Council) endeavoured to implement HSCI according to the precepts of the Act; working to both (re)configure and hold things together behind care frontiers; away from the bodywork of direct care, immersed in everyday arrangements in the spaces of governance and operations. I chart their efforts to comply with regulations, plan, and build governance apparatuses through documents. I explore through coalescent objects how distributed forms of governance, entwined in policy implementation, were subsequently both sustained, and challenged. I observed for seven months actors struggling to (re)configure care services embedded in a collaborative approach, as well as establish the legitimacy of the HSCP; exemplified through the fabrication of what was understood as a 'must-do' commissioning plan. In tracing documents, I show the ways in which HSCI was simultaneously materialised and constituted through documentation. I reveal how, in the mundane mattering of document manufacturing, possibilities for (re)forming the carescape emerged. By delving into inconspicuous, ‘seamful’ b/order work that both sustained distinctions between the NHS and Council and enabled b/order crossings, I expose how actors were knotted, and how this shaped efforts to recompose the contours of the carescape. While ‘Kintra’s story might be familiar, situated in concerns that may resonate across Scotland; I reveal how collaboration-as-practice is tangled in differing organisational practices, emerging from quotidian intra-actions in meeting rooms, offices, car parks and kitchenettes. I deploy a posthuman practice stance to show not only the way in which public administration ‘does’ care, but it’s world-making through a sociomaterial politics of anticipation. I was told legislation was the only way to make HSCI in ‘Kintra’ happen, nevertheless, there was resistance to limit the breadth and depth of integrating. Consequently, I show how the (re)organising of b/orders was an always-ongoing act of maintenance and repair of a (dis)integrating carescape; as I learnt at the end of my fieldwork, ‘it’s ‘Kintra, ‘it’s aye been!

    Φυσιολογικά χαρακτηριστικά και επιδράσεις των μεταγγιζόμενων ερυθροκυττάρων ως συνάρτηση της βιολογικής ποικιλομορφίας αιμοδοτών και δεκτών

    Τα ερυθροκύτταρα συνιστούν το συχνότερα μεταγγιζόμενο παράγωγο αίματος. Ωστόσο, κατά την αποθήκευσή τους σε συνθήκες τράπεζας αίματος υφίστανται μια σειρά χρονο-εξαρτώμενων και μη, αντιστρεπτών και μόνιμων φυσιολογικών, δομικών και βιοχημικών αλλαγών, οι οποίες αποδίδονται με τον όρο «Αποθηκευτική βλάβη ερυθροκυττάρου». Οι βλάβες κατά την αποθήκευση ex vivo μπορούν να διακριθούν σε: α) Βιοχημικές αλλαγές (μείωση ΑΤΡ, επιδεκτικότητα σε οξειδωτικό στρες κ.α.), β) Μηχανικές αλλαγές (ικανότητα ελαστικής παραμόρφωσης, αλλαγή σχήματος κ.α.) και γ) Μεμβρανικές αλλαγές (εξωτερίκευση δεικτών απομάκρυνσης, αλλαγές στο πρωτέωμα της μεμβράνης κ.α.). Τα τελευταία χρόνια έχει παρατηρηθεί μια τεράστια μεταβλητότητα στην αποθηκευτική ικανότητα και την μετα-μεταγγισιακή ανάκτηση, μετά την αποθήκευση αίματος από διαφορετικούς δότες. Για άγνωστους λόγους τα ερυθροκύτταρα συγκεκριμένων δοτών, κατηγοριοποιημένων βάσει γενετικά καθορισμένων χαρακτηριστικών (π.χ. φύλο) ή περιβαλλοντικών παραγόντων (π.χ. κάπνισμα), εμφανίζουν αποκλίνουσα αποθηκευτική ικανότητα. Πράγματι, πλέον πολλές φυσιολογικές ιδιότητες των αποθηκευμένων ερυθροκυττάρων μπορούν να θεωρηθούν «κληρονομήσιμοι χαρακτήρες» ή εξαρτώμενοι από εγγενή χαρακτηριστικά του αιμοδότη. Aνάμεσα σε αυτές συγκαταλέγονται: η εντός του ασκού αιμόλυση, η 24ωρη ανάκτηση in vivo, τα επίπεδα ΑΤΡ, η αποδοτικότητα μεταφοράς οξυγόνου, η συσσώρευση δεικτών οξειδωτικού στρες κ.α. Στην παρούσα Διατριβή μελετήθηκαν αιμοδότες με ετεροζυγωτία στη β-μεσογειακή αναιμία (βΜΑ), ένα συχνό γενετικό χαρακτηριστικό στη χώρα μας. Είναι γνωστό πως οι ετερόζυγοι για βΜΑ που εμφανίζουν ενδοκυττάρια αιμοσφαιρίνη άνω των ορίων της αιμοδοσίας, δεν αποκλείονται από αυτήν. Παράλληλα, τα ερυθροκύτταρά τους παρουσιάζουν κάποιες διαφορές σε σύγκριση με τον μέσο αιμοδότη, όσον αφορά για παράδειγμα κλασικές αιματολογικές παραμέτρους, το οξειδοαναγωγικό ισοζύγιο και την ιοντοανταλλαγή. Ωστόσο, ούτε το πρότυπο της αποθηκευτικής βλάβης, ούτε η ανάκτηση και άλλα χαρακτηριστικά της μετα-μεταγγισιακής κατάστασης των αποθηκευμένων ερυθροκυττάρων είναι γνωστά για αυτούς τους αιμοδότες. Με βάση τα παραπάνω, σκοπός της παρούσας Διατριβής ήταν ο εκτενής και εμπεριστατωμένος έλεγχος του αίματος, και κυρίως των ερυθροκυττάρων ετερόζυγων για βΜΑ αιμοδοτών, στους τρεις κρίκους της αλυσίδας της μετάγγισης: in vivo πριν την αποθήκευση, στο παράγωγο κατά την αποθήκευση συμπυκνωμένων ερυθροκυττάρων και in vitro/in vivo μετά τη μετάγγιση με τη χρήση in vitro/ζωικών μοντέλων. Στο φρέσκο αίμα και τα αποθηκευμένα ερυθροκύτταρα αιμοδοτών με ή χωρίς στίγμα βΜΑ μελετήθηκαν παράμετροι φυσιολογίας (αιμόλυση, οξειδοαναγωγικό ισοζύγιο, μορφολογία, πρωτεόσταση), καθώς και μεταβολωμική ανάλυση των ερυθροκυττάρων. Επιπλέον, κατά την αποθήκευση πραγματοποιήθηκε πρωτεωμική ανάλυση των ερυθροκυτταρικών μεμβρανών και των κυστιδίων που συσσωρεύονται στη μονάδα μετάγγισης. Για το in vitro μοντέλο μετάγγισης, αποθηκευμένα ερυθροκύτταρα των δύο κατηγοριών αιμοδοτών επωάστηκαν σε πλάσμα από πιθανούς δέκτες (ομόζυγους για βΜΑ ή υγιείς) για 24 ώρες σε θερμοκρασία σώματος, προτού αναλυθούν διάφορες παράμετροι της φυσιολογίας τους. Τέλος, στο ζωικό μοντέλο μετάγγισης, ερυθροκύτταρα περιφερικού αίματος και από μονάδες μετάγγισης των δύο κατηγοριών αιμοδοτών σημάνθηκαν με φθορίζουσες χρωστικές και χορηγήθηκαν σε ανοσοεπαρκείς και ανοσοανεπαρκείς μύες για να υπολογιστεί συγκριτικά η 24ωρη ανάκτησή τους. Σύμφωνα με τα αποτελέσματα, οι αιμοδότες με ετεροζυγωτία σε μεταλλαγές της βΜΑ αποτελούν μη αμελητέο ποσοστό του αιμοδοτικού πληθυσμού της χώρας μας και τα ερυθροκύτταρά τους αντιμετωπίζουν εντυπωσιακά το αποθηκευτικό στρες, καθώς βρέθηκαν ανθεκτικά σε λύση ανεξαρτήτως ερεθίσματος και διέθεταν βελτιωμένο οξειδοαναγωγικό ισοζύγιο σε σύγκριση με εκείνα του μέσου αιμοδότη. Μάλιστα, η αντίσταση σε κυτταρική λύση φάνηκε να είναι άρρηκτα συνδεδεμένη με την ιδιαίτερη γεωμετρία των κυττάρων των ετερόζυγων και τη σταθερότητα δομικών πρωτεϊνών κατά την πρόοδο του χρόνου αποθήκευσης. Επιπλέον, το σύνολο των αποτελεσμάτων, είτε αφορούν στη φυσιολογία και το μεταβολισμό είτε στην πρωτεϊνική σύσταση και την πρωτεόσταση, σχηματίζει την εικόνα ενός κυττάρου καλά προσαρμοσμένου σε σταθερά πλην ήπια επίπεδα οξειδωτικού στρες, έτοιμου να αντιμετωπίσει περαιτέρω οξειδωτικές προκλήσεις. Για παράδειγμα, τα επίπεδα των αντιοξειδωτικών και πρωτεοστατικών ενζύμων βρέθηκαν πλεονεκτικότερα στα κύτταρα των ετερόζυγων, τα οποία παράλληλα έφεραν μειωμένες οξειδωτικές βλάβες και χαμηλότερο οξειδωτικό φορτίο, κυρίως προς το τέλος της αποθηκευτικής περιόδου. Με δεδομένο το βασικό ρόλο του οξειδωτικού στρες στην πρόοδο της αποθηκευτικής βλάβης, φαίνεται πως τα ερυθροκύττραρα με στίγμα βΜΑ μπορούν, χάρη στην «εκπαίδευσή» τους σε ελαφρώς αυξημένο οξειδωτικό φορτίο, να την αντιμετωπίζουν πλεονεκτικότερα. Η «υπεροχή» σε επίπεδο αποθήκευσης, που αντικατοπτρίζεται έντονα στα μειωμένα επίπεδα αιμόλυσης (μοναδικό ποιοτικό χαρακτηριστικό της αποθήκευσης αίματος σύμφωνα με τον Παγκόσμιο Οργανισμό Υγείας), συνοδευόταν και από βελτιωμένο πρότυπο απόκρισης σε μετα-μεταγγισιακό στρες. Τα αποτελέσματα από τα in vitro και ζωικά μοντέλα μετάγγισης συγκλίνουν και (α) αναδεικνύουν τη διατήρηση πλεονεκτικότερης κυτταρικής φυσιολογίας μετά τη μετάγγιση, και (β) υπαινίσσονται αυξημένη 24ωρη in vivo ανάκτηση των μεταγγισμένων ερυθροκυττάρων (μοναδική μετα-μεταγγισιακή μέτρηση επιτυχούς μετάγγισης σύμφωνα με τον Παγκόσμιο Οργανισμό Υγείας) στην περίπτωση των ετερόζυγων για βΜΑ. Μέσω στατιστικής ανάλυσης για εύρεση συσχετίσεων αναδείχθηκαν χαρακτηριστικά όπως οι χαμηλοί δείκτες ευθραυστότητας, το μέγεθος των κυττάρων καθώς και η ισχυρή εξωκυττάρια αντιοξειδωτική ικανότητα των μονάδων ετερόζυγων φορέων να σχετίζονται με χαμηλή μετα-μεταγγισιακή αιμόλυση και επιβίωση των ερυθροκυττάρων τους στην κυκλοφορία του δέκτη. Φαίνεται λοιπόν πως ορισμένες παράμετροι που διακρίνουν τους ετερόζυγους in vivo ή/και κατά την αποθήκευση δεν είναι ουδέτερες ως προς τη μετα-μεταγγισιακή φυσιολογία/επάρκεια των ερυθροκυττάρων τους.Erythrocytes are the most frequently transfused blood product. However, during their storage in blood bank conditions, a series of time dependent or independent, reversible, or irreversible, physiological, structural and biochemical changes occur, which are attributed to the term "Erythrocyte Storage Lesion". Defects during ex vivo storage can be distinguished into: a) Biochemical changes (ATP depletion, susceptibility to oxidative stress, etc.), b) Mechanical defects (deformability, morphology changes, etc.) and c) Membrane lesions (externalization of removal markers, changes in the membrane proteome, etc.). In the last years, a huge variability in storage capacity and post-transfusion recovery has been observed after storing blood from different donors. For unknown reasons the erythrocytes of distinct donors, categorized by genetically determined characteristics (e.g., sex) or environmental factors (e.g., smoking), show divergent storage capacity. Indeed, many physiological properties of stored erythrocytes can now be considered "heritable characters" or dependent on intrinsic characteristics of the blood donor. Among them are in-bag hemolysis, 24-hour in vivo recovery, ATP levels, oxygen transport efficiency, accumulation of oxidative stress markers, etc. In the current thesis, the distinct blood donor group that was studied were eligible donors with heterozygosity for beta-thalassemia (bThal), a frequent genetic trait in our country. It is known that bThal heterozygotes who show intracellular hemoglobin above the threshold for blood donation are considered eligible. At the same time, their red blood cells (RBCs) differ compared to the average blood donor in classic hematological parameters, redox balance, and ion exchange, among other. However, neither the storability profile nor recovery and other characteristics of the post-transfusion state are known for stored erythrocytes from these blood donors. Based on the above, the aim of this thesis was the extensive and thorough examination of blood, and mainly of RBCs, from heterozygous bThal blood donors, in the three links of the transfusion chain: in vivo (namely, before storage), in the blood unit during the storage period, and post-storage or after transfusion by using in vitro or in vivo (animal) models of transfusion, respectively. Physiological parameters (hemolysis, redox balance, morphology, proteostasis) as well as metabolomic analysis of RBCs were performed in fresh blood and stored erythrocytes of blood donors with or without bThal trait. In addition, proteomic analysis of erythrocyte membranes and extracellular vesicles (which accumulate in the supernatant of the transfusion unit) was performed during storage. For the in vitro transfusion model, stored RBCs of the two cohorts of blood donors were incubated in plasma from potential recipients (with bThal major or healthy) for 24 h at body temperature, prior the analyses. Finally, in the animal model, erythrocytes from peripheral blood and from the blood units of the two categories were labeled with fluorescent dyes and administered to immunocompetent and immunodeficient mice to comparatively calculate their 24-hour recovery. According to the results, blood donors with heterozygosity for bThal mutations constitute a non-negligible percentage of the blood donation population of our country. Their erythrocytes cope with storage stress, as they were found resistant to lysis regardless of the stimulus and exhibited an improved redox balance compared to those of the average blood donor. In fact, resistance to cell lysis appeared to be inextricably linked to the distinct geometry of the heterozygotes’ cells and the stability of structural proteins during the progression of storage time. Furthermore, the results in total, whether they concern physiology and metabolism or protein composition and proteostasis, point to a cell well-adapted to steady but mild levels of oxidative stress, ready to face further oxidative challenges. For example, the levels of antioxidant and proteostatic enzymes were found to be more advantageous in RBCs from bThal heterozygotes, while the same cells also showed reduced oxidative damage and lower oxidative load, especially towards the end of the storage period. Given the key role of oxidative stress in the progression of storage damage, it seems that bThal-trait erythrocytes are able, thanks to their "training" to a slightly increased oxidative load, to deal with it more effectively. The "superior" storability of bThal units (strongly reflected in the reduced levels of storage hemolysis, namely, the gold quality parameter of blood storage according to the World Health Organization) was also accompanied by an improved pattern of post-transfusion stress response. Results from both in vitro and animal models of transfusion converge and (a) highlight the maintenance of the more advantageous cellular physiology post transfusion, and (b) imply an increased 24-hour in vivo recovery of transfused RBCs (the gold quality measure of successful transfusion according to World Health Organization) in the case of bThal heterozygotes. Through correlation analysis, distinguishing characteristics of heterozygotes, such as low RBC fragility indices and cell size, as well as strong extracellular antioxidant capacity were shown to be associated with low post-transfusion hemolysis and better survival of their erythrocytes in the recipient's circulation. It therefore appears that some parameters that differentiate heterozygotes in vivo and/or during storage are not neutral with respect to the post-transfusion physiology/adequacy of their erythrocytes

    Magnetic Flux Leakage techniques for detecting corrosion of pipes

    Oil and gas pipelines are subjected to corrosion due to harsh environmental conditions as in refinery and thermal power plants. Interesting problems such as internal and external corrosion, emerging from the increasing demand for pipeline protection have prompted this study. Thus, early detection of faults in pipes is essential to avoid disastrous outcomes. The research work presented in this thesis comprises investigations into the use of magnetic flux leakage (MFL) testing for pipe in extreme (underwater and high temperature) conditions. The design of a coil sensor (ferrite core with coil) with a magnetic circuit is carried out for high temperature conditions. The sensor thus developed lays the ground for non-destructive evaluation (NDE) of flaws in pipes through the MFL technique. The research focusses on the detection and characterization of MFL distribution caused by the loss of metal in ferromagnetic steel pipes. Experimental verifications are initially conducted with deeply rusted pipe samples of varying thicknesses in air. AlNiCo magnets are used along with Giant Magneto Resistance (GMR) sensor (AA002-02). The experiment is further repeated for saltwater conditions in relation to varying electrical conductivity with radio frequency identification (RFID) technique. A further study carried out in the research is the correlation between magnetic and underwater data communication. The study has resulted in the development and experimental evaluation of a coil sensor with its magnetic response at room and high temperatures. This makes the system effective under high temperature conditions where corrosion metal loss needs to be determined
