“…As recapitulated in Table 2, a handful of methods for alternatives problems have been described in the document, most of the techniques in the document are from the field of MCDM, such as OPA [20][21][22][23], fuzzy Technique for Order Performance by Similarity to Ideal Solution (FTOPSIS) [6,[24][25][26], Gray model [27][28][29], NFAD [30,31]. This issue may have been partially solved by previous papers using Data Envelopment Analysis (DEA) models [22,30,[32][33][34][35][36], and other MCDM [6,24,26,28,[37][38][39][40][41][42]. The authors apply or combine these methods to compare results.…”

Geothermal energy is considered a renewable, environmentally friendly, especially carbon-free, sustainable energy source that can solve the problem of climate change. In general, countries with geothermal energy resources are the ones going through the ring of fire. Therefore, not every country is lucky enough to own this resource. As a country with 117 active volcanoes and within the world's ring of fire, it is a country whose geothermal resources are estimated to be about 40% of the world's geothermal energy potential. However, the percentage used compared to the geothermal potential is too small. Therefore, this is the main energy source that Indonesia is aiming to exploit and use. However, the deployment and development of this energy source are still facing many obstacles due to many aspects from budget sources due to high capital costs, factory construction location, quality of resources, and conflicts of the local community. In this context, determining the optimal locations for geothermal energy sites (GES) is one of the most important and necessary issues. To strengthen the selection methods, this study applies a two-layer fuzzy multi-criteria decision-making method. Through the layers, the Ordinal Priority Approach (OPA) is proposed to weight the sub-criteria, the main criterion, and the sustainability factors. In layer 2, the Neutrosophic Fuzzy Axiomatic Design (NFAD) is applied to rank and evaluate potential locations for geothermal plant construction. Choosing the right geothermal energy site can bring low-cost efficiency, no greenhouse gas emissions, and quickly become the main energy source providing electricity for Indonesia. The final ranking shows Papua, Kawah Cibuni, and Moluccas as the three most suitable cities to build geothermal energy systems. Kawah Cibuni was identified as the most potential GES in Indonesia, with a score of 0.46. Papua is the second most promising GES with a score of 0.45. Next is the Moluccas, with a score of 0.39. However, the three least potential sites among the 15 studied sites are Lumut Balai, Moluccas and Patuha, with scores of 0.08, 0.11 and 0.17, respectively. The conclusion of this study also classifies positions into groups to aid in decision-making.

En la actualidad las tuberías son el principal método de transporte de fluidos de un lugar a otro, dentro de una planta industrial. La presente investigación estudia la configuración de tuberías de un sistema de bombas de transporte de hidrocarburo. Se realizó una investigación para identificar las diferentes cargas presentes en diseños de los sistemas de bombas, debido a efectos de peso propio y térmicos operativos, con el fin de reducir los esfuerzos, desplazamientos que actúan en las tuberías, garantizando su integridad mecánica como la seguridad de equipos y personal de planta. El desarrollo del modelo y análisis se realizó en el software especializado Bently AutoPIPE en condiciones estáticas, los datos operativos de temperatura y presión son 100 °F y 320 psi respectivamente. Para el análisis, se emplearon dos modelos de configuración; tuberías con sistema rígido y flexible, permitiendo comparar resultados y validar que los esfuerzos en tuberías y boquillas de bombas se encuentren dentro de las cargas admisibles de acuerdo con las normas ASME B31.3 y API 610. Con base en los resultados del análisis, los esfuerzos en sostenido y térmicos son 16.3 y 14.4 ksi, valores que representan aproximadamente el 75 % del esfuerzo máximo del sistema

“…Due to the occur of the complex chemical reactions, the corrosion issue in the piping systems influenced to loss of mineral represented by the brown layer and to decrease of the thickness in lifetime, where the pitting forms change and turn into semi-elliptical depth or length depending on the nature of materials and operating conditions [17][18][19]. These problems have become great obstacles on the piping systems including elbows [19][20][21], valves, and components of piping installations, where many studies were performed the impact of defects on the structures, which lead to change the mechanical characteristics, thus it must need to repair by welding [20][21][22][23] or by material composites [23][24][25][26].…”

The aim of the project is to study experimentally the influence of the semi-elliptical defect on the steel of grade API 5L X52 pipeline and its reparation by welding operation to keep the safety of hydrocarbons transport network. The tests have been performed on the specimens with/without semi-elliptical defects by using two ratios a/c and a/t, where the defects issue on the piping systems wall is treated by using the welding operation, which focuses on the filling the defected surface as same thickness of the base wall of the pipeline after removing the defects. The decrease of ultimate stress is mainly evident depending on the size of crack, where they compared to the base metal results. The experimental results showed that the reliability of the welding operation is proved especially in the ratio a/c =1, which is similar to that found in automatically welded. It is proved that the ratio a/t = 0.2 curve exhibits similarity to the base metal curve and their elongation conforms to API standard of steel X52 grade. Clearly, corrosion defects cause degradation of mechanical property in the order of 44% to 50% depending on the ratio of 0 < a/c ≤1 and from 20% to 80% according to the second ration of 0 < a/t ≤0.8. The obtained results proved that the enhanced of mechanical properties by welding reaches to ultimate stress is 559 MPa for the ratio a/t = 0.2 and 531 MPa for the ratio a/t = 0.5. Finally, the experimental results provided that the impact of semi-elliptical defect has effects on the safety of piping systems where welding became as one of among solutions to repair the piping systems.
