    Data analysis on automation of purging with IoT in FRAMO cargo pump
    (Routledge, 2024-05-06) Kumar, R. Prasanna; Devi, V. Ajantha
    Oil and chemical tankers use the FRAMO system to transport cargo from ship to shore. FRAMO cargo pumps, which are installed inside cargo tanks, are an essential component of the system. The results of the purging operation are used to determine whether or not these cargo pumps are operationally ready. The purging procedures confirm the integrity of the sealing arrangements on both the cargo and hydraulic systems. The cofferdam that separates the cargo from the hydraulic fluid collects any leakage from the FRAMO cargo pump’s seals. The AUDRINO control board and electronic control of various solenoid-signaled hydraulic actuated valves are recommended for this auto- mated purging procedure. Control signals from the shore control center or the inbuilt timer circuit can be delivered via IoT. This control board also oversees the purging sequence. The leak-off liquid is lifted from the cofferdam space to the sample container by automated purging. The identification of the liquid is essential for obtaining the purging result. The method proposed in this paper employs three distinct sensors to identify the liquid in the cofferdam space in the autonomous ship environ- ment. The three parameters are density meter, pH meter, and a color sensor. These three characteristics distinguish the cargo liquid from the hydraulic oil used in the system. This test result is useful for cargo operation plan- ning. The content received in the cofferdam is revealed by comparing the measured data set to the preloaded database. The major goal of this research is to use physicochemical data to predict oil content. Two distinct data sets were obtained in this investigation. These data sets include three major cargo and hydraulic oil physicochemical properties. Using the random forests algo- rithm, the instances were effectively identified as cargo oil or hydraulic oil with an accuracy of 98.6229%. The detection of both cargo oil and hydraulic oil was then classified using three distinct data mining techniques: k-near- est-neighbor, support vector machines, and random forests. The random for- ests algorithm provided the best accurate classification.

    Issues and challenges in Indian academic libraries after COVID-19 period
    (2020) Devendrappa, T.M.; Nageswara Rao, K. N; Mayuri, Naga Krishna A.; Jain, Rishabh Kumar
    The purpose of writing of this book chapter is to create the awareness among the library professionals during period of covid-19 instant what all the changes happened in academic library environment, issues and challenges faced by library professionals. How the professionals are tackled the situation to came out from the issues and challenges to provide the library services for users community. How the library professionals shown the importance of library to academic institution and they make users to realize the importance of library in academic activities. The various new kinds of services and techniques brought in use by various library professionals examples are presented for future use for other professionals in India and across the world. In this article, some of the initiatives taken are observed for providing free information to general public usage by government and other non government organizations.

    Hongkong convention: impact on environment due to refrigeration waste in ship recycling: an Indian perspective
    (Interdisciplinary Research in Technology and Management, 2021-09) Das, Krishnendu.; Sivasami, K.; Thangalakshmi, S.; Das, N.
    Considering strict environmental concerns and compliances to protect our Globe, sustainable developments in maritime domains comprises of ship building process, transport by shipping and ship recycling process. All three phases having concerns to environmental impacts, but evidence of the impacts of present ship recycling process undermines the Maritime Education’s contribution to sustainable development. Ship breaking process includes complete scrapping or partially dismantling of vessels. At the yard, various parts, equipment, hull sections, superstructure materials, pipes, gears etc. are segregated after dismantling. These segregated scraps are recycled and re-use in various industry which is the most important business for ship breaking industry. About 85% ship recycling of the globe are mainly in Bangladesh, India, China and Pakistan, where environmental impacts and health hazards are serious concerns same mentioned by Vally Athanasopoulou. In India, ship recycling process from long time is following in primitive way which is unsafe and has tremendous health hazards.
