    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 Mohan
    Modern-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.

    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 Mohan
    With 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.

    A Study on the challenges and opportunities of reverse logistics innovation in rural areas
    (International Conference on Innovation and management: The Way Ahead, 2022-09-29) Ajay Kumar, Kanithi; Adinarayana Rao, U. V.; Bhanu Prakash, N.
    Reverse logistics (RL) is a dynamically evolving process, where goods meant for returns or repairs move from the customer to the producer. This study is an attempt to explore the current status, challenges and opportunities in RL with a focus on selected rural areas. The study proposes certain pertinent innovative measures for the implementation of RL in underserved rural areas. Related case studies were used to illustrate the possible impact of RL innovation. By using empirical findings from case studies, it can be shown that some fundamental differences in logistics innovation exist. To identify possible reverse logistic innovations in rural areas, this study had undertaken an extensive literature review accompanied with personal interaction and observations with the various logistics service providers (LSPs). Along with the opportunities, the barriers in front of the establishment of a RL system and the contribution of innovation in overcoming these challenges are discussed.

    Numerical computation of Boil off Rate (BoR) in shipboard LNG tanks
    (IOP Publishing, 2022) Eswara, Arun Kishore; Sandilya, P.
    Natural gas is an environment-friendly fuel and a raw material for many chemicals. Its offshore transport is economical when the gas is transported in liquefied form as Liquefied Natural Gas (LNG) over distances (exceeding 2000 kilometers) by sea. LNG is stored at near-atmospheric pressure and about 112 K in these tanks. Heat inleak from the ambient into the stored LNG causes considerable boil-off of the LNG due to low latent heat of vaporization of LNG. Boil off Gas (BoG) generation should be reduced to minimize the loss of LNG as well as environmental pollution. Determination of the boil-off rate (BoR) poses a challenge because it involves interplay of multitude of phenomena and considerations, like liquid sloshing that is likely to generate heat and increases the interfacial area between the liquid and the ullage, variation in LNG composition due to BoG generation, and thermal stratification. In this paper we present a numerical analysis of the BoG generation, including some of the effects just mentioned. A model including transport phenomena based-equations and thermodynamic phase relations has been developed for this purpose.The simulation results would help in carrying out more in depth study of BoG generation that is useful in the design and operation of the prismatic membrane tanks.

    Is outsourcing the Panacea? a discourse on the sustainability of Indian ports a case of Jawaharlal Nehru port trust
    (International Association of Maritime Universities, Alexandria, Egypt, 2021-10-27) Mitra, T; Pattanaik, K. M.
    The discourse on sustainable transportation illuminates the fact that port competitiveness and efficiency gains are two major pillars of blue economy in a world which is much integrated than in the past. However, most literature on port efficiency measurement undermine the very eco system of a port. Port eco system is complex interconnected web of network which requires collaborative involvement of spate of stakeholders such as CFS, Agents, ICDs, Transportation companies, to mention a few. Understanding such network and their holistic potential impact on the efficiency of port performance is scarcely addressed in the context of larger dialogue on port efficiency. Such an analysis is paramount when deeper levels of economic integration and spatially competitive ports are considered to be co joint twins. Further, efficiency gains of ports have received much academic attention in view of total quality management which focuses on customer delight and thus customer retention. It is this regard; the present paper tries to make an infant endeavour in terms of measuring terminal efficiency with respect to the turnaround time which would include export cycle time and import cycle time of CFS (a potential outsourcing activity of a port). Such a step in efficiency measurement of ports is scanty in Indian scenario. A case of Jawaharlal Nehru Port Trust is referred as a case in point.

    Alternate fuel
    (National Conference on Energy, Environment and Sustainable Shipping (NCESS), 21-22 December 2020, 2020-12-22) Hare, Ram Hare
    As the world moves towards greener solutions for reduction in pollution by any source, the transportation industry will be greatly affected and hence major changes are taking place throughout. From automobiles, logistics, aviation and each and every machine in the supply chain is looking to cut down the emissions. Shipping contributes to 3% of the world’s total manmade carbon emissions. Around the world, air pollution is causing serious health problems and premature death, and local air pollution will be subject to tougher regulations over the coming years. Reducing emissions to air and introducing new propulsion technologies are key challenges for the worldwide transport sector, including shipping. The world’s future fleet will have to rely on a broader range of fuels, propulsion solutions and energy efficiency measures. All alternative fuel options have benefits and challenges. This guidance paper provides an introduction to alternative fuels and technology solutions. It includes an overview of selected alternative ship fuels – LNG, LPG, methanol, biofuel and hydrogen – as well as emerging technologies such as batteries, fuel cell systems and wind-assisted propulsion. The objectives of the paper are to provide decision support for investment in ships for the upcoming period. The paper focuses on technical parameters and limitations without accounting for local market conditions, considerations and incentive schemes which may have a significant impact on competitiveness and the uptake of alternative fuels and technologies. Marine fuel currently contributes approximately 3 per cent to global man-made CO2 emissions. Most seagoing ships are still using heavy fuel oil (HFO) or marine gas oil (MGO), with a maximum sulphur limit of 3.5 per cent (mass) in force for HFO and 0.1 per cent (mass) for low- sulphur MGO. Looking at the future with the IMO 2020 low-sulphur standards and upcoming CO2 emission regulation regime in mind, the share of conventional oil-based ship fuels will drop and the share of alternative fuels will grow. Prerequisites for introducing a new fuel include availability of sufficient production and distribution facilities as well as an adequate bunkering infrastructure. In addition, new fuels in many cases require extensive on- board modifications and a reversal to a conventional system is complex and costly.

    Impact of Tamarindus Indica biodiesel blends on performance and exhaustemissions characteristics of light duty compression ignitionengine
    (Materials Today: Proceedings, 2021) Jayashri N Nair; Satyanarayana Murthy, Y.V.V.
    Tamarind (Tamarindus Indica) is an integral part of South Indian cuisine. Its pulp is used to add sourness to southIndian curries. However tamarind seeds which are having a considerable amount of lipid in it are thrown away. Ourmain objective is to produce Tamarind biodiesel (TB) from tamarind seed oil and investigate its effect onperformance and exhaust emissionsof CI engine. Oil was extracted from Tamarind seeds and was converted to biodiesel by transesterification process with NaOH as catalyst. Tests were performed using TB5, TB10, TB15 blendswith 1500 rpm rated speed and compression ratio of18. The performance test results revealed that BTE of B15 wasgreater in comparison to other blends as well as diesel . However BSFC for TB blends were greater compared to neat diesel . Considerable reductions in exhaust emissions were observed with TB blends. TB10 showed apical reductionof 27% in CO and 15% reduction in smoke. TB5 showed 25% HC reduction followed by TB10 with 19.25% reductions.TB15 showed 19.36% of highest NOx reduction followed by TB10 with 10.7% NOx reduction. TB10 proved to giveoptimum test results for performance and emissions. From the results it can be concluded that TB can be consideredas a viable option for biodiesels.

    Machine learning methods for marine systems
    (IOP Conference Series: Materials Science and Engineering, 2021) Thangalakshmi, S.; Sivasami, K.
    Automation plays a key role in shipping industry and aims towards minimal operating staff. However, the effective automation relies on effective controlling at various levels starting from shipbuilding to navigation. The industry is currently focussing on autonomous shipping which actually requires precise controlling. Although many conventional methods are available for control and automation with regard to automation, Artificial Intelligence Schemes (AIS) are widely attracting the maritime sector because of their benefits. The AIS along with fuzzy logic systems are offering promising results. The emerging use of AIS in a variety of maritime applications can act as a reference wpoint for new researchers. This paper aims to conduct a valid AIS study and to examine the various machine learning approaches used in various maritime applications. It is possible to achieve complete automation in the shipping industry by implementing a related technique.

    Real time monitoring and controlling of marine sewage treatment plant effluent
    (2022-02) Prasanna Kumar, R.; Ajantha Devi, V.
    As on date around 56,000 vessels are moving in the World shipping fleet and it is growing every day. All these vessels were manned by seafarers who spend on an average of 6 months on-board. Their continuous stay onboard required the basic hotel service such as food, climate controlled Accommodation and all lavatory facilities. On top of this thousands of passenger ferries and cruise liners floating on the oceans also providing similar facilities for nature-calls of passengers. Discharge of these wastes from sewage system affects the marine environment, particularly in the confined water bodies similar to Baltic sea. One of the important requirements as per MARPOL (International conventions for the prevention of Pollution from ships,1973) by IMO is maintaining sewage treatment plant (STP) onboard[1]. This part has been specified in detail as ANNEX-IV – Prevention of Pollution by Sewage from ships[1]. Standards for Sewage treatment plant placed on-board is evaluated basis on the contents in the effluent from the plant after all processes completed. This evaluation is not performed on every STP fitted in so many numbers of vessels in service today. As a part of pre- building exercise STPs were chosen from list of type approved systems available. This type approval is issued by marine administrators by sample evaluation of one of the plant in the factory environment. This paper proposed the model STP in which the data from Real time monitoring the contents in the effluent can be used to regulate the air supplied to the plant. Different sensors such as microorganism detector, PH prob, Phosphorous sensor and Nitrogen detector of instant results types used for this purpose. To regulate the supplied air, frequency controlled motor is used in the supply–air Fan. This regulation of air will reduce the energy requirement of the overall process. Added with the regulation of air supply, real-time control on feed rate of dosing pump optimize the chemical use in the plant. Nitrogen and Phosphorus contents continues measurements and flowmeter readings from inlet and outlet of the plant ensure the effective performance of Full treatment module. This proposed model plant will be an energy efficient and real-time compliance to the international limitations stated in MARPOL.
