Full textAbstract:
The Tangential Guanabara Bay Aeration and Recovery (TAGUBAR) project derives its origins from a Brazilian government decision to tackle the planning and management challenges related to the restoration of some degraded aquatic ecosystems such as Guanabara Bay (state of Rio de Janeiro), Vitória Bay, and Espírito Santo Bay (state of Espírito Santo). This was performed by using the successful outcomes of a previous Ministry of Foreign Affairs and Directorate General for Cooperation and Development (i.e., Direttore Generale alla Cooperazione allo Sviluppo, MFA–DGCS) cooperation program. The general objective of the program was to contribute to the economic and social development of the population living around Guanabara, Vitória, and Espírito Santo Bays, while promoting the conservation of their natural resources. This objective was supposed to be achieved by investing money to consolidate the local authorities’ ability to plan and implement a reconditioning program within a systemic management framework in severely polluted ecosystems such as Guanabara Bay, where sediments are highly contaminated. Sediments normally represent the final fate for most contaminants. Therefore, it would be highly undesirable to perturb them, if one wishes to avoid contaminant recycling. In this context, we explored a bench-scale novel technology, called the module for the decontamination of units of sediment (MODUS), which produces an oxygenated water flow directed parallel to the sediment floor that is aimed to create “tangential aeration” of the bottom water column. The purpose of this is to avoid perturbing the top sediment layer, as a flow directed toward the bottom sediment would most probably resuspend this layer. Three kinds of tests were performed to characterize a bench-scale version of MODUS (referred to as “mini-MODUS”) behavior: turbulence–sediment resuspension tests, hydrodynamic tests, and oxygenation–aeration tests. In order to understand the functioning of the mini-MODUS, we needed to eliminate as many variables as possible. Therefore, we chose a static version of the module (i.e., no speed for the mini-MODUS as well as no water current with respect to the bottom sediment and no flume setting), leaving dynamic studies for a future paper. The turbulence tests showed that the water enters and exits the mini-MODUS mouths without resuspending the sediment surface at all, even if the sediment is very soft. Water flow was only localized very close to both mouth openings. Hydrodynamic tests showed an interesting behavior. An increase of low air flows produced a sharp linear increase of the water flow. However, a plateau was quickly reached and then no further increase of water flow was observed, implying that for a certain specific geometry of the equipment and for the given experimental conditions, an increase in the air flow does not produce any reduction of the residence time within the aeration reactor. Oxygenation–aeration tests explored three parameters that were deemed to be most important for our study: the oxygen global transfer coefficient, KLa; the oxygenation capacity, OC; and the oxygenation efficiency, OE%. An air flow increase causes an increase of both KLa and OC, while OE% decreases (no plateau was observed for KLa and OC). The better air flow would be a compromise between high KLa and OC, with no disadvantageous OE%, a compromise that will be the topic of the next paper.

Abstract Conceptual cost estimation is important for construction projects. Either underestimation or overestimation of building raising cost may lead to failure of a project. In the paper authors present application of a multicriteria comparative analysis (MCA) in order to select factors influencing residential building raising cost. The aim of the analysis is to indicate key factors useful in conceptual cost estimation in the early design stage. Key factors are being investigated on basis of the elementary information about the function, form and structure of the building, and primary assumptions of technological and organizational solutions applied in construction process. The mentioned factors are considered as variables of the model which aim is to make possible conceptual cost estimation fast and with satisfying accuracy. The whole analysis included three steps: preliminary research, choice of a set of potential variables and reduction of this set to select the final set of variables. Multicriteria comparative analysis is applied in problem solution. Performed analysis allowed to select group of factors, defined well enough at the conceptual stage of the design process, to be used as a describing variables of the model.

Although many global MBA programs teach intercultural communication, what happens when the method for teaching that concept becomes mostly experiential? To answer that question, the authors took two very similar classes, both composed of working adults, a Business Communications course in Germany and a Managerial Communications course in the United States, and joined the students into a project that spread over several weeks and had a purposely vague deliverable. While the students believed that the policies and presentations were the most important aspect of the project, the actual aim of this exercise was for them to learn about intercultural communication by doing it. Based on weekly debriefs and a final debrief, group presentations, and individual papers, we concluded that students had increased their understanding of intercultural communication far beyond what they would have gained by merely studying intercultural theory.

PurposeThe purpose of this paper is to examine information-seeking behavior (ISB) of strategic planners in enterprise across different work-task types and stages.Design/methodology/approachA case study was conducted in a pharmaceutical company in China, labeled as T Company. One of the authors worked in the department of strategic planning of this company as an intern. The data were collected via participant observation and unstructured in-depth interviews. Open coding was performed to analyze the data.FindingsFour work-task stages were identified: project preparation, gathering, discovery and presentation, and strategy formulation. The results indicate that work-task types, work-task stages, and strategic planners’ work role or position affect their information needs, source selection, and seeking process. Task complexity, task familiarity, and task goal are of the most important task attributes that directly shape strategic planners’ ISB. Work role determines the extent to which strategic planners can access the information of the company. Internal information has priority, but external information is also important when internal information is not sufficient; both are equally important for strategic planning projects. Social media has been a very important channel to access, disseminate and share information. Workshops are an important approach to producing final project reports. Face-to-face discussion and information exchange play a critical role in the formulation of new strategies.Research limitations/implicationsThis is a case study with data collected from only one company in China. Some of the results may not be generalizable. However, it adds new knowledge to ISB research in enterprise, informs people how to provide better information services for strategic planners, and informs MBA education for students’ better information-seeking skills.Originality/valueThough myriad studies on ISB, little research has been done to examine strategic planners’ ISB from a business context, especially taking into account the effect of work-task types and stages.

Full textAbstract:
The main purposes of this project are to assess and to optimize the solubility of carbon dioxide (CO2) in an aqueous 30 wt% monoethanolamine-tetrabutylphosphonium methanesulfonate (MEA-[TBP][MeSO3]) new hybrid solvent. In this study, the viscosity and density of aqueous MEA-[TBP][MeSO3] hybrid solvents containing different amounts of [TBP][MeSO4] were determined. Meanwhile, Fourier Transform-Infrared (FT-IR) Spectroscopy was used to determine the presence of carbamate in aqueous MEA-[TBP][MeSO3] to prove that CO2 was absorbed by aqueous MEA-[TBP][MeSO3]. Response Surface Methodology (RSM) based on central composite design (CCD) was used to design the experiments and explore the effects of three independent parameters on the solubility of CO2 in aqueous MEA-[TBP][MeSO3]. The three independent parameters are concentration of [TBP][MeSO3] (2–20 wt.%), temperature (30–60 °C) and pressure of CO2 (2–30 bar). The experimental data was found to fit a quadratic equation using multiple regressions and analyzed using analysis of variance (ANOVA). The final empirical equation in terms of actual factors was deducted as mol fraction = 0.5316 − (2.76 × 10−4)A − (8.8 × 10−4)B + (8.48 × 10−3)C + (2.9 × 10−5)AB + (2.976 × 10−6)AC + (5.5 × 10−5)BC − (8.4 × 10−5)A2 − (3.3 × 10−5)B2 − (1.19 × 10−4)C2, whereby A = ionic liquid ([TBP][MeSO3]) concentration, B = temperature and C = CO2 pressure. An attempt was made to perform the experiments for solubility of CO2 in aqueous MEA-[TBP][MeSO3] to validate the removal of CO2 predicted by RSM. Based on a validation study, the experimental data showed a percentage error between 0.6% and 2.11% as compared to the predicted value of CO2 removal by RSM.

Full textAbstract:
The increased demand for Internet courses, especially in schools of business, has raised questions about instructional interaction and teacher-student immediacy, which online courses may lack. Because current research suggests immediacy behaviors may indeed be present, we developed a strategy for measuring immediacy in an online MBA course and related the results to student grades on final team projects in the course. Learner-to-learner, noncontent-related statements showed minimal affective behavior, but that lack did not have a negative effect on grades. The study suggests that students do not automatically provide supportive feedback, compliment each other, and express appreciation or agreement unless the instructor builds a learning community and transfers interactive roles to the students themselves.

Full textAbstract:
Teaching communication to MBAs often involves focusing on corporate strategic discourse when student projects are intended to help companies move to a more advanced stage of development. This focus on corporate strategy—the language and concepts that concern the mission and direction that an organization should adopt—requires, in turn, that faculty enact several roles to assist students in developing their final assignments, strategic presentations, and reports. Faculty play the role of specialists in corporate strategy, communication specialists, and stand-ins for the primary audience(s) for these assignments. Working with students on these assignments underscores two important values in MBA education: providing students with the means to engage in discussion at the CEO level where decisions about the company’s strategic direction are made, and demonstrating to students that the strategic assignments they produce belong to a larger communication campaign for getting buy-in for corporate strategy. These teaching practices foster research projects as well.

Full textAbstract:
My stoneware sculptures in my MFA final project were named Earth Divers because clay as a material is earth and clay is also symbolic of the Earth. The way that I physically dive into clay up to my elbows is a poetic performance. The sculptures were built in sections horizontally and then stacked vertically. I began the process by first making life size plaster molds of the human figure taken from live people. Earth Divers take their architectural structure specifically from the organic curves of the negative voids that are characteristic of the plaster figure molds. I built into these plaster molds a block or brick like section. I then removed the large block sections from the molds and stacked the sections one on top of the other combining the figurative and architectural structures with gothic influence. The sculptor, Stephen De Staebler, who works in a similar fashion, describes his work as, "... first laying the figure down and later standing it in a vertical position." The way of life that was lost with the manufacturing past of my family at Castone Brick is found in the use of industrial nostalgia by modeling I-beam shapes as part of the structure of the stacked sections. I also fired nuts, bolts, and washers of various sizes in the clay that build the surface of the human forms. The square nut seen in my work is no longer being manufactured and is symbolic of the passing of the industrial age in America. Finally, to build the surfaces of my sculptures I used slips, glazes, and a variety of clays on top of clay, and laid glass fragments on the horizontal surfaces to create a look of pooled water when my work was fired similar to what I have seen in the Lehman Caves in Baker, Nevada. "I believe there is a force in this world that lives beneath the surface, something primitive and wild that awakens when you need an extra push just to survive, like wild flowers that bloom after a fire turns the forest black. Most people are afraid of it and keep it buried deep inside themselves. But, there will always be a few people who have the courage to love what is untamed inside us." (Tim McGraw)

The performer who studied in final year (2018) Master Degree did the exploration and discussion on the graduation project [Dream.Afterglow] where she found out that there were difference between the level to emerge into the connotation and performance skills if compare to Degree’s final year performance and the former had deeper and more layers in emotional expression from the inside to outside; the interaction between the performer's self-action and the stage’s atmosphere should make ones performance more mature. Moreover, this chance was uneasy to get, the performer should be cherished and enjoyed the stage moment. The dance relates to the meaning of and action, dance is life itself; dance communication, narratives or self-expression; self-centered, independent and valuable projection of the outside world. As an interpreter of performance art, not only concern on the body movement but also from the life experience of cumulative precipitation and emotion. Then perform this sensation and inner feeling through the physical movements to convey the message to the audience. In return, there are three-point emotional exchange between the writer, the dancer and the audience. Dance is an expression of movement, time and space performance art. Therefore, when the dance moves are in progress, the movement will follow the rhythm and due to the changes in time, different dance rhymes and different styles will be formed , Zhang Pei Yu said (Chang Peiyu, 2015, III). The researcher has been studied dancing performance art for nearly a decade and has been trained in different genre and style. Chinese dance is unique in its introverted movements of Chinese dance and aesthetics. This is the first independant performance that going to complete in the Master Degree course ever. The researcher showed the passion and aspiration through [Dream‧Afterglow]. Moreover, she showed herself whole-heartedly and tranmited her own dance life value.As Ling Cheng Wei said, emotion can apply into the performance through training. In addition, the spirit and consciousness are being transmitted (Ling Chengwei, 2004, 38). The researcher has experienced a unique emotion on people, matters and things in her life. The researcher initiated the planning, production and execution in [Dream.Afterglow]. She took her life experiences as a thought in this dance content. The feelings of long in thoughts showed the past scene, by using the lotus growth image to described current life experience. Exploring the dreams, routes and directions of the future with the help of the mother nature. There were three different songs used in different dance styles which were "Think", "Lotus Pond" and "Day of the Dream". The researcher, by using the Chinese dance and style, role interpretation, dance image aesthetics and other literature aid, she analized her own participation in the production, and used the text in dancing to interpret the characters, explore and examine her own body in the performance. From the feedback of this production experience, good communication and coordination needed to take into consideration for future production team and some suggestions for future dancers which confident and mature dance interpretation method were needed much in the future.

This chapter presents an approach for designing secure Data Warehouses (DWs) that accomplish the conceptual modeling of secure DWs independently from the target platform where the DW has to be implemented, because our complete approach follows the Model Driven Architecture (MDA) and the Model Driven Security (MDS). In most of real world DW projects, the security aspects are issues that usually rely on the DBMS administrators. We argue that the design of these security aspects should be considered together with the conceptual modeling of DWs from the early stages of a DW project, and being able to attach user security information to the basic structures of a Multidimensional (MD) model. In this way, we would be able to generate this information in a semi or automatic way into a target platform and the final DW will better suits the user security requirements.

Full textAbstract:
The Reactor Pressure Vessel (RPV) is an essential component liable to limit the lifetime duration of PWR plants. The assessment of defects in RPV subjected to PTS transients made at an European level generally not always account the beneficial effect of load history (warm pre-stress WPS) on vessel resistance regarding the risk of brittle failure. A 3-year Research & Development program — SMILE — has been started in January 2002 as part of the 5th Framework Program of the European Atomic Energy Community (EURATOM). The SMILE project — Structural Margin Improvements in aged embrittled RPV with Load history Effect — is one of a cluster of 5th framework projects in the area of Plant Life Management. It aims to give sufficient elements to demonstrate, to model and to validate the beneficial WPS effect in a RPV assessment. Within the framework of the project, an important experimental work has been conducted including WPS type experiments on CT specimens and one PTS type transient experiment on a large component. The WPS type experiment on the cylinder has been successfully conducted by MPA Stuttgart with a final brittle failure during the reloading. The present paper shortly describes the experiment and presents the corresponding analyses based on engineering methods, finite element elastic-plastic computations, and local approach to fracture. The results are in good agreement with the experimental observations. Very significant margins are underlined, with an effective important increase of the material resistance regarding the risk of brittle failure.

SPE, 2021. http://dx.doi.org/10.2118/202131-ms.
Full textAbstract:
Abstract 107 new wells are planned to be drilled primarily from two new Artificial Islands during the period of one project from 2023 to 2029. The number of existing wells in the oil field has reached 1,068 Mother bores, 2,178 wellbores @16,453,666ft total well length as of December 2019. Trajectories, especially from existing Artificial Islands, are getting more complex so as to avoid collision issues, and it is becoming increasingly difficult to drill accordingly. It is of great importance to assure that it is possible to drill the planned wells without serious collision issues before the execution of the project. Trajectories for planned wells were drafted one-by-one utilizing "DecisionSpace Well Planning" based on the predetermined slot allocation with the planned drilling pad design. Geological models are incorporated into DecisionSpace Well Planning. Therefore, formation tops were taken into account in order to make the trajectories more realistic. After that, trajectories were exported to "COMPASS" and anti-collision scan was performed on well-by-well basis. Anti-collision scan was performed among planned wells as well as actual wells. In case that one well has such serious collision issues that the well cannot/should not be planned based on company policy as a result of Anti-collision scan, trajectory or Landing Point (LP)/Total Depth (TD) location were adjusted. Then, Anti-collision scan was carried out again. If it was confirmed that there is no serious Anti-collision issues, trajectory was considered as final. It has been found that all the wells during the period from 2023 to 2029 can be drilled without serious collision issues by slightly adjusting LP/TD while satisfying several practical drilling requirements. Through the Anti-collision study, following recommendations for the avoidance of collision were obtained:Multi Station Analysis (MSA)+In-Field Referencing (IFR)+SAG correction should be applied in all the Jack up operations as well as Island operationsApplication of real-time MSA should be considered on a case-by-case basisMWD survey for the past wells should be corrected with IFR+MSA to reduce EOU sizeRe-Gyro jobs for low-quality survey wells should be enhanced around the project's development areaKick off point (KOP) should be deeper in the center of the drilling pad and shallower in the edge of the drilling pad

Full textAbstract:
The European EUREKA project EU 209 or AGATA - Advanced Gas Turbine for Automobiles is a program dedicated to the development of three critical ceramic components; i. catalytic combustor, ii. radial turbine wheel, iii. static heat exchanger, designed for a 60 kW turbogenerator hybrid electric vehicle. The objective is to develop and test the three components as a full scale feasibility study with an industrial perspective. The AGATA partners represent car manufacturers as well as companies and research institutes in the turbine, catalyst and ceramic material fields in France and Sweden. The program has been running since early 1993 with good progress in all three sub-projects. The turbine wheel design is now completed. FEM calculations indicate that the maximum stress occur during cold start and is below 300 MPa. Extensive mechanical testing of the Si3N4 materials from AC Cerama and C&C has been performed. The catalytic combustor operates uncooled at 1350°C. This means a severe environment for both the active catalyst and the ceramic honeycomb substrates. Catalysts with high activity even after aging at 1350°C have been developed. Ceramic honeycomb substrates that survive this temperature have also been defined. The catalytic combustor final design is ready and the configurations which will be full scale tested have been selected. The heat exchanger will be a ceramic recuperator with 90 % efficiency. Both a tube concept and a plate concept have been studied. The plate concept has been chosen for further work. Sub-scale plate recuperators made of either cordierite or SiC have been manufactured by C&C and tested.

Linear infrastructure routing experts struggle with providing rationale for final route selections that are defensible, transparent, open to two-way stakeholder communication, and ultimately scientifically rigorous and repeatable. Likewise, proponents are wise to adopt a front-end, risk-based approach to proactively identify, mitigate or possibly avoid routing decisions that may result in stakeholder opposition and costly permitting and/or approval delays. This paper discusses an approach using Geographic Information Systems (GIS) and a highly structured multi-criteria spatial analysis (MCA) to identify potentially optimal corridors and routes based on best available environmental, social, economic and technical spatial datasets. This approach can be used by multidisciplinary project teams to systematically capture, explore and record routing protocols and assumptions, and then extrapolate these considerations through GIS modelling into simulated corridor and route options which can then be quantitatively analyzed, compared, documented and communicated. Early identification and mitigation of project routing risks may help reduce or avoid costly project delays at later stages. Stakeholder communication and consultation can be incorporated at each stage in order to inform routes and explore trade-offs, as well as communicate routing rationale in an open, constructive and meaningful way. The resulting benefits of this approach include a robust and comprehensive rationale, providing proponents with a clear and compelling “story” in support of public and stakeholder consultation as well as the regulatory approval process.

Full textAbstract:
In the final evaluation for the application of the Master Curve in the IAEA Coordinated Research Project Phase 5 (CRP-5), one of the areas which was identified as needing further work concerned the effects of loading rate on the reference temperature To up to impact loading conditions. This subject represents one of the three topic areas within the current CRP-8. The effect of loading rate can be broken down into two distinct aspects: 1) the effect of loading rate on the Master Curve To values for loading rates within the specified in ASTM E1921-05 for quasi-static loading (0.1–2 MPa√m/s); 2) the effect of loading rate on To values for higher loading rates, including impact conditions using instrumented precracked Charpy (PCC) specimens. The new CRP includes both aspects, but primarily focuses on the second element of loading rate effects, i.e. loading rates above 2 MPa√m/s. These issues are investigated within the topic area #2 of CRP-8 (Loading Rate Effect). The mandatory portion of this topic area required participation in a round-robin exercise (RRE) to validate the application of the Master Curve approach to PCC specimens tested in the ductile-to-brittle transition region using an instrumented pendulum (10 tests per participant on the JRQ material). The current status of the RRE is presented in [1]. The non-mandatory portion of this topic area consists in providing Master Curve data obtained at different loading rates on various RPV steels, in order to assess the loading rate dependence of To and compare it with an empirical model proposed by Wallin. Moreover, additional topics will be addressed, such as: • comparison of results from unloading compliance and monotonic loading in the quasi-static range; • estimation of fracture toughness from Charpy V-notch data; • assessment of crack arrest properties from instrumented Charpy results; • effect of irradiation on the relationship between static and dynamic fracture toughness.

Full textAbstract:
As part of a program to increase the operating pressure of a 20” (508.0mm) natural gas pipeline, a careful plan was developed and executed to ensure the integrity of the pipeline. The pipeline was built in 1943 using linepipe produced having a DC ERW longitudinal seam weld and travels along a densely populated route in the suburbs of Philadelphia. The work plan included ILI inspection methods to detect corrosion (MFL tool), mechanical damage (geometry tool), and ERW seam weld defects (TFI MFL tool). After the anomalies were identified and the necessary pipe replacements were completed, the pipeline was hydrostatically tested prior to being returned to service at the newly established operating pressure. The paper will describe the project planning process used to ensure the fitness and reliability of the pipeline and provide a review of the ILI results, excavations, pipe replacements, and hydrostatic test experiences. Of particular interest were the capabilities and limitations of the TFI tool to detect, discriminate, and size ERW seam weld defects. Seam weld defects were evaluated using ILI inspection methods and in many cases field prove-up ultrasonic inspection methods. When an ERW defect was confirmed by field NDT prove-up, the pipe section was removed and metallographic work was conducted to characterize the ERW flaw size and nature. A correlation was then possible between the sizing capability of the TFI tool, the ultrasonic prove-up method, and the actual defect size. All this information is useful to establish a level of confidence in defect sizing for future project needs. The final validation of the pipeline fitness at the higher operating pressure was established through the successful hydrostatic test. A short summary will be given on how the pipeline fitness was qualified and demonstrated.

Full textAbstract:
The four-year European Gas Turbine Program “AGATA” was started in Jan 1993 with the objective to develop three critical components aimed at a 60 kW turbogenerator in an hybrid electric vehicle — a catalytic combustor, a radial turbine wheel and a static heat exchanger. The AGATA partners represent car manufacturers as well as companies and research institutes in the turbine, catalyst and ceramic material fields in both France and Sweden. This paper outlines the main results of the AGATA project for the first three year period. During the third year of the program, the experimental verification of the components has started. A high pressure/temperature test rig for the combustor and the heat exchanger tests has been built and is now being commissioned. A high temperature turbine spin rig will be ready late 1995. The turbine wheel design is completed and ceramic Si3N4 spin discs have been manufactured by injection moulding and Hot Isostatic Pressing (HIP). A straight blade design has been selected and FEM calculations have indicated that stress levels which occur during a cold start are below 300 MPa. The catalytic combustor final design for full scale testing has been defined. Due to the high operating temperature, 1350°C, catalyst pilot tests have included ageing, activity and strength tests. Based on these tests, substrate and active materials have been selected. Initial full scale tests including LDV measurements in the premix duct will start late 1995. The heat exchanger design has also been defined. This is based on a high efficiency plate recuperator design. One critical item is the ceramic thermoplastic extrusion manufacturing method for the extremely thin exchanger plates another is the bonding technique: ceramic to ceramic and ceramic to metal. Significant progress on these two items has been achieved. The manufacturing of quarter scale prototypes is now in process.

Abstract Unique characteristics of individual pipelines come from over a century of evolving design, construction, maintenance, regulation and operation. These characteristics are especially true for legacy, pre-regulated pipelines. Due to the unique nature of the threats present on these assets, there is a need for unique inspection technologies and techniques that can increase pipeline integrity. Reconditioned and repaired pipe utilizing puddle weld repairs is one such threat. An advanced analysis was completed on a 10-inch, 68-mile light products pipeline. The pipeline was constructed with reconditioned pipe that was estimated to contain tens of thousands of puddle welds. Historical in-line inspection (ILI) data generally underperformed in classifying and discriminating puddle welds versus metal loss features. The primary objective of this project was to assess the probability of identification (POI) of a multiple dataset ILI tool utilizing multiple magnetic flux leakage (MFL) magnetization directions and residual (RES) magnetization measurements. A secondary objective was to scrutinize data for signs of coincident features. Hydrostatic testing failures showed that puddle welds with porosity and cracking were susceptible to failure and that the identification of these features would be beneficial. Analysis of historical puddle weld investigations and newly completed multiple dataset ILI data revealed strong identification capabilities in the RES dataset. The high-field magnetizations offered secondary confirmation but often saturated out thermal effects or material differences. The final report included over 40,000 identified puddle welds and five classifications for further investigation. Field investigations for 212 features were completed and the results compared to the ILI data to assess performance. A confusion matrix was created for true positive (TP), true negative (TN), false positive (FP) and false negative (FN) conditions. The smallest TP puddle weld dimension was 0.7″ × 0.7″, and the population had a statistical sensitivity value of 98% (132 TP and 3 FP). Three additional anomalies denoted as atypical were also investigated. The ILI signatures at these locations were consistent with previous repairs in which puddle welds with cracking were found and repaired. Two of the three features investigated were found to have cracking. Crack propagation was found to be both axial and non-axial in orientation. The results show that puddle welds can be detected and identified with extremely high accuracy. In addition, the preliminary classification results for atypical puddle welds show a high potential for identifying secondary coincident features. This paper details the stages, deliverables and results from an ILI advanced analysis focused on puddle welds.
