Item Linking Leadership Integrity - Depression, Anxiety and Stress (DAS) among Sailing Indian Marine Engineers During Covid-19(Barcelona School of Nautical Studies, Barcelona, 2024-06-05) Mitra, Toorban; Pattanaik, Krushna MohanModern-day leadership demands competencies to embrace challenges and uncertainties as a part of a working career. Uncertainties bring in many unknown outcomes and a loss of direction to any team. This is much acknowledged when the unknown outcomes are affecting the team spirit and, in turn, organisational sustainability. Leadership integrity is a watershed to handle such uncertainties with positive outcomes. Like in any other business domain, uncertainties are part of the business in shipping. However, there are specific instances in the nature of COVID-19 that came with many challenges, like extended work contracts, no shore leaves, infrequent crew change, quarantine rules before sign-in, online surveys, etc. Such an uncertain and challenging work environment on board a ship (which itself is an organisation) results in anxiety, stress and depression. In this context, leadership integrity provides much-needed direction and can create a healthy work environment in any organisation. It is in this context that this paper tries to measure this hypothesis in an explorative study, particularly among active marine engineers who worked on board ships during the COVID-19 pandemic. Such knowledge facilitates the understanding of organisational behaviour during challenging times and provides a timely prescription for organisational success during uncertainties and challenging times with much significant focus on the integrity of leaders.Item Logistics performance as facilitator to trade performance: An Indian perspective(The International Maritime Transport and Logistics Conference "MARLOG 13", 2024-03-03) Dasgupta, Mrinal Kumar; Mitra, Toorban; Pattanaik, Krushna MohanWith the growing realisation of the importance of global integration in the production and consumption value chain, the importance of maritime logistics and transportation facilitating international trade is profoundly recognised. Further, a proliferation of collaborative trade agreements among different trade partners is ascribed to play a significant role. However, such external dynamics and engagements in international trade would propel blue economic growth if backed by strong maritime logistics initiatives and establishment. In this context, deep routed challenges, particularly in the domestic maritime logistics sector in manufacturing hubs like India, could potentially hamper her comparative advantages in international trade. It is in this context that this paper comes as an intercession by analysing India’s Logistics Performance Index (LPI) and its impact on trade performance. Also, this paper provides a comparative analysis of India’s LPI with that of other trade competitors from South and East Asia and tries to find out challenging areas of maritime logistics for India and suggest the required policy prescription thereof. Such acknowledgement is a compulsion for a country like India when escalated uncertainties due to episodes of COVID-19, the Russia-Ukraine War, and dips in the business cycles of many countries that demanded green and resilient supply chain and logistics practices. The paper prescribes that domestic reforms to ease out challenges in Indian maritime logistics coupled with external engagements would provide a flat form for India to reap the optimal gains from international trade.Item Outsourcing of logistics and global competitiveness –A case study on Jawaharlal Nehru Port Trust(Indian Maritime University and Academy of Maritime Education and Training, Chennai, 2019) Mitra, Toorban & Pattanaik, Krushna MohanWith the emergence of global competitiveness in port sector, it is imperative that a port is not just operational but also effective in its service provision. Logistics performance, ceteris peribus, stimulates this effectiveness of a port significantly in terms of its performance. In this context it is illuminated that outsourcing of logistic activities and competitiveness of a port are co-habitants. In view of the present background set, the present study makes an intervention to explore performance of various outsourced stakeholders involved in logistic service provision for Jawharlal Nehru Port Trust (JNPT) which may include service provision of various Container Freight Stations (CFS), Inland Container Depots (ICD) and Logistic Operators under JNPT. Using secondary data collected from various stake holders to establish standard port operation indicators, this paper makes an endeavor to measure the comparative performance of each of these stakeholders which in turn would facilitate their respective macro operational impact on the effectiveness of JNPT to face growing global competitiveness in the coming times. As a follow up, strategic options are suggested for improvement and retention of competitive performance of outsourced stakeholders involved in logistics service provisions in JNPT’s operations.Item Overcoming the Traditional Barriers and Reaching the Users at the Doorstep with the Trending Technology(VICLIS2021, 2021) Padmashree, Samavedam; Sasikala, CahgariItem Influence of Technology in women Entrepreneurship(International Seminar on Women Entrepreneurship and Globalization: Issues and Challenges, 2018-02) Ravichandran, N.Item Evaluation of river regulatory measures in hughly estuary using tidal asymmetry characteristics(IEEE, 2006) Sivakholundu, K. M.; Kathiroli S.; Mani J. S.; Idichandy V. G.Tidal asymmetry has a profound effect on estuarine hydrodynamics and sedimentation pattern. The information of tidal asymmetry can be a useful tool to evaluate the flow pattern in shallow estuary and characterize the dominance of flood or ebb flow. The effects of features (like obstructions, depressions, etc.) and discharge variation in a theoretical channel section is simulated to quantify the parameters of tidal asymmetry. A set of proposed river regulatory measures in a shallow estuary (Hughly, India) was taken up for evaluation using tidal asymmetry parameters to check whether this may be used as additional tool. The indications provided (flood dominance and hence sediment importing regime) with asymmetry parameters do match with field conditions (based on bathymetry survey data). The asymmetry parameters may be put to use to evaluate the change in flood/ebb dominance in relative terms in a given section.Item Design of sustainable shore protection solution using geosynthetic tubes(GA 2016 - 6th Asian Regional Conference on Geosynthetics, 2016) Kiran, A.; Ravichandran, V.; Jebakumar, P.; Abhishek, T.; Sivakholundu, K. M.Item Application of parametric acoustics for shallow-water near-surface geophysical investigations(IEEE, 2006-05) Vasudevan, Manoj; Sivakholundu, K. M.; Venkata Rao, D.; Kathiroli, S.Shallow-water near-surface geophysical investigations were carried out, under two different scenarios - one to assess the status of a pipeline in the West coast and the other to assess the effect of water-injection dredging in the East coast of India. In both these investigations, Parametric Sediment Echo Sounder (SES-2000), a system developed by Innomar Technologie GmbH, which makes use of the parametric acoustical effect, was used. In the former case, profiles were taken across a pipeline at regular intervals to determine whether it was buried or exposed. The parametric system produces a 2D geo-acoustic section in which the pipe is indicated by a hyperbolic curve. The exposed height or buried depth of the pipeline at a crossing is then estimated. This investigation could, also, reveal the geomorphologic changes in the immediate vicinity of the pipeline. In the latter case, parametric acoustics was utilized to provide supplementary results for the assessment of water-injection dredging. Parametric acoustic data could expose the abrupt termination of certain near-seabed layer interfaces and sediment accumulations along steep slope, quite convincingly. SES-2000 proved to be handy to investigate the near-surface sub-seabed, especially in areas where conventional or popular methods find practical difficulties to be carried out.Item Holistic approach to project CWC with altair(Altair Technology Conference, 2015-07) Bhavaraju, Pradeep J. S.A Circulating Water Channel (CWC) generates a controlled flow environment and is used for various hydrodynamic research activities including flow around ships, study of fishnets, etc. The current paper utilizes various modules of ALTAIR HYPERWORKS to provide a holistic solution in completing the project i.e, modelling using SOLIDTHINKING, flow analysis across the working section of the CWC using ACUSOLVE, and developing a mechanism to generate ship motions with MOTIONSOLVE. One of the many experiments that can be conducted with the CWC is an internal tank sloshing test. A free surface flow analysis is performed for a 2D tank using RADIOSS solver validating the same with existing experimental results.Item Analysis of antifouling paints using drum test apparatus(RINA, 2015-12) Joshi, Madhu; Mukherjee, A.; Misra, S. C.; Ramesh, U. S.Ship has been recognized as a major factor in introduction of non-native and harmful organisms which causes deleterious effects on the performance of the vessel. More than 70% of Invasive species worldwide have found to be due to hull fouling. To mitigate fouling, underwater parts of the vessels are coated with antifouling paints. Antifouling paints provide foul-free hulls up to a maximum of 95 % of the vessels underwater area. There are a number of types of these paints but “self-polishing coatings” are predominantly preferred by the shipping industry. In these types of coatings, a thin layer of biocide containing paint (typically 2 to 5 microns/month) is leached or “polished” away. This polishing action primarily depends on the hydrodynamic surface forces on the vessels hull. The higher the fluid velocity, the higher are the polishing rate. Certain areas of the vessel such as near the bow, stern, etc experience higher fluid velocity and therefore higher polishing rates thereby resulting in premature fouling. Conversely, areas where the flow rates are considerably smaller would experience lesser polishing rates which would result in insufficient amount of biocides being delivered which would again result in premature fouling. In order to study and estimate the polishing rates of Anti Fouling paint we have designed, fabricated a rotating drum test facility .Wall shear stress are to be calculated by CFD methods
