2024	Development of a Marine Traffic Simulator on Google Maps using Nomoto’s K-T Model. The Google Maps application is the most widely used and easily accessible map tool. This study endeavours to create a Marine Traffic Simulator leveraging the Google Maps API and Nomoto’s K-T Model. The objective is to enable the real-time analysis of a ship’s planar motion directly on Google Maps, which applies to any waterbody worldwide. The research also seeks to develop a real-time program capable of steering a ship, utilising an external control device like a steering wheel or joystick. While the K-T model provides a fundamental and straightforward assessment of planar motion, it offers only a fundamental estimation. The ultimate goal of this research is to lay the groundwork for integrating more precise and intricate models of ship motion directly into the Google Maps platform.	Md.

2024	Foil Shape Optimisation using Machine Learning Based Surrogate Model Shape optimisation is crucial in aeronautical and maritime industries, often requiring extensive Computational Fluid Dynamics (CFD) simulations, leading to high computational time and cost. Sometimes, thousands or more simulations must be implemented for optimal design. Computational time and cost can be significantly reduced by using the prediction of a surrogate model. Artificial neural networks effectively construct surrogate models for predicting optimal designs, significantly reducing computational power and time. This study uses a machine-learning-based surrogate model to perform foil shape optimisations. The “Hicks-Henne bump function” has been used to parameterise and deform the original shape according to design parameters. Sampling parameters are generated using quasi-random low-discrepancy sequences called “Sobol” sequences. Numerical simulations have been conducted using the potential flow-based panel method solver “XFOIL” to obtain lift and drag coefficients of deformed foil shapes. An ANN-based surrogate model has been trained to predict the lift-coefficient and drag-coefficient corresponding to design parameters. The Python library “scipy. optimise” has been used to optimise the surrogate model to obtain optimal design parameters. The objective is to maximise aerodynamic efficiency, and a constraint was set to keep the drag coefficient less than the original airfoil. The optimised shape obtained from the process enhances the overall efficiency, making it applicable for diverse purposes ranging from marine propellers, stabilisers, fin, and rudder sections to aerodynamic wing shape sections. The optimisation process also can be used for many engineering shape optimisation processes.

Ongoing	A Carbon Credit Prediction Model for Mitigating Waste-Induced Carbon Footprint from Passenger Vessels in Bangladesh Bangladesh’s river network consists of nearly 230 rivers, serving as crucial transportation routes for millions of passengers annually. Unfortunately, the absence of monitoring and implementation of effluent-releasing standards in Bangladesh has habituated the direct dumping of untreated waste into water bodies. Despite ratifying international conventions on marine pollution, Bangladesh lacks a National Marine Environmental Protection Policy, as noted by the UNDP. This research aligns with the urgent need for a sustainable model in the maritime sector, considering the inadequate waste management practices and the country’s vulnerability to climate change. The Carbon Credit Prediction model integrates biogas, a composting plant within a passenger ship, and a plastic segregation chamber to prevent water and air pollution and promote sustainable practices. The biogas and composting plant effectively process organic waste from ships, producing biogas for cooking as a safe and sustainable alternative to Liquefied Petroleum Gas (LPG). The plastic segregation chamber ensures proper storage and sale of plastic waste for recycling, reducing the need for new plastic production and promoting a circular economy. Initial findings reveal a noteworthy reduction in CO2eq emissions per ship, accompanied by daily biogas production to substitute for Liquefied Petroleum Gas (LPG), thereby diminishing reliance on imports. This model seeks to verify the overall CO2eq reduction using established methodologies, enabling the allocation of carbon credits that are designed to reduce GHG emissions by incentivising emissions reductions in developing countries like Bangladesh. Emphasising the imperative for an eco-friendly waste management strategy to safeguard Bangladesh’s marine environment, the model seamlessly aligns with Sustainable Development Goals (SDGs). It contributes to environmental protection by substantially reducing greenhouse gas emissions, promoting energy independence, and establishing a more sustainable infrastructure through the provision of carbon financing incentives while addressing the long-standing waste management problems in Bangladesh’s maritime sector.

Ongoing	A Quantitative Analysis of Ferry Accidents in the Inland Waterways of Bangladesh Inland ferry transportation plays a crucial role in Bangladesh’s transportation network, connecting various regions and facilitating the movement of goods and people. However, the safety of inland ferry operations is a growing concern due to the increasing frequency of accidents. This research aims to develop a comprehensive risk assessment model using advanced computational techniques, specifically Markov Chain Monte Carlo (MCMC) and Mathematical Maneuvering Group (MMG) Model simulations. The primary objectives of this research are to develop a statistical model for assessing the probability of inland ferry accidents using MCMC simulations and to incorporate vessel maneuvering dynamics into the risk assessment through the application of MMG Models. After that, an evaluation of the effectiveness of the proposed model in predicting and mitigating inland ferry accident risks will be done. This research is significant for enhancing the safety of inland ferry transportation in Bangladesh by providing a comprehensive and dynamic risk assessment model. The outcomes can inform policy decisions, improve safety regulations, and guide infrastructure development to reduce the occurrence and severity of inland ferry accidents.

2023	A Study of Ocean Wave Energy Harnessing Using a Piezoelectric Device at Various Wave Conditions This research project focuses on developing theoretical and mathematical models to assess total output voltage under varying parameters in different wave conditions. The Morison equation calculates the force acting on a surface pile where a Piezo device is strategically placed. Given the device’s sensitivity and fluctuating magnitude, a customised Simulink circuit is constructed to maintain a consistent current flow. The output voltage vs. wave height graph analysis reveals increased voltage generation with higher wave heights. Two real-world locations are examined to validate these findings, with a consideration of seasonal variations in wave height. Additionally, the study explores practical applications of piezoelectricity.	Masum Alam Riyad Abu Raihan Rakib Md.

2023	Mathematical Modeling and Simulation of Heat Dispersion Due to Fire and Explosion During Ship-Cutting In this study, a mathematical model has been developed to evaluate heat dispersion during a flash fire outside a ship. The model was solved using computational fluid dynamics (CFD) and produced discretised equations for heat flux and temperature. The model was tested by simulating a flash fire outside a ship using MATLAB. It can simulate heat dispersion following a fire incident with defined boundary constraints and a case with a wind factor. This model analyses parameters such as heat flux and temperature, which are found to be time and space-dependent. Analysing the results, this model can determine a safe distance for those aboard the ship. The study also shows that the range of this safe distance will change if the air velocity changes. For vapor cloud explosion inside the ship, an analytical method was used to determine the side-on peak overpressure, providing insights into the explosion risk inside a ship compartment. Finally, both models can estimate the risk of fire and explosion. They can be used to develop preventive procedures to decrease the potential damage caused by fire and explosion during ship-cutting.

2021 – 2022	A Probabilistic Risk Analysis of Marine Railway Type Docking Docking is a crucial part of a ship’s lifecycle. Among different types of docking, Marine Railway type docking is one of the most common methods. While docking a ship in this method, many risks are involved such as wire failure, wheel derailment, power failure, breakage of chain of winch, breakage of block wood, etc., some of which can result in great financial loss. In this study, a probabilistic risk analysis approach is introduced. A physics-based mathematical model is developed for a “Marine Railway” type dockyard in Bangladesh based on which probabilistic risk analysis is carried out. Prediction of number of failures that could occur within a certain period is evaluated. Some relevant measurements are proposed to decrease risks while using the Risk Control Option.	Md.

2021 – 2022	Application of Machine Learning in Ship Maintenance: Cathodic Protection Prediction of net anode mass for underwater hull surface protection from corrosion at the design stage or repairing of a vessel can ameliorate the cathodic protection design of the ship. When a ship moves through water, it faces corrosion due to electrochemical process between ship hull and chemical substance present in that water. A well-designed cathodic protection can increase the life span of the ship preventing that electrochemical corrosion. The prime task in designing cathodic protection is to determine the current density (CD) of the hull material. In traditional process, the CD is whether determined by a simulation software or empirically, which are complicated and takes time. So use of machine learning for determining CD can be a smart, cost effective and time saving process.

2020 - 2021	Prediction of Hydrodynamic Coefficients of Rolling Motion of Floating Structure with Machine Learning Algorithm Machine learning has become a pivotal force in the rapidly advancing industrial landscape, finding applications in diverse sectors, including shipbuilding and operation. This research employs machine learning techniques to predict hydrodynamic coefficients governing the rolling motion of floating structures in marine environments. The rolling motion is mathematically described as a second-order equation comprising three forces: motion, resistance, and restoring balance. Artificial neural networks and specific algorithms are leveraged in machine learning, with a three-layer neural network serving as the training model. This model involves an input layer with four components, a hidden layer processing and connecting these components, and an output layer providing the outcome. The study meticulously compares projected results with analytical findings, revealing the impact of rolling even in calm waters. Additionally, the research delves into the time required for the rolling motion to complete, highlighting its intricate nature. The overarching goals include simplifying complex processes, enabling early-stage vessel stability evaluations, and offering a more accessible and efficient approach that reduces reliance on resource-intensive simulation tools. This knowledge equips designers to confidently assess and ensure vessel stability during the initial design phase.

2017 – 2018	Performance Evaluation & Economic Design of a Remotely Operated Underwater Vehicle (ROV) Bangladesh is a riverine country and a maritime nation. The country manufactures a lot of ocean-going and inland ships which are mostly constructed and maintained in the dockyards situated near the inland rivers of Bangladesh. During maintenance and underwater inspection of these ships, divers are deployed and often these divers face hazardous and life-threatening situations. Due to high siltation in the riverbeds, the view factor of the river water is not favorable. Also, the topology of the river bed is constantly changing which often creates a problem for ship navigation. With these problems in mind, this research attempts to develop an autonomous underwater vehicle which can be used for underwater hull inspection and underwater topology scanning. The primary focus of this research is to develop suitable controller and evaluate the controller performances in different environmental conditions. The research focuses on the performances of various combinations of PID controllers in controlled and uncontrolled experimental setups. Another important objective of this research is to manufacture an inexpensive prototype which can make an impact in the competitive world market.

2017 – 2018	Risk Assessment of Inland Passenger Vessel Operation in Bangladesh using Hazard and Operability (HAZOP) Analysis The objective of this research is to identify all the hazards and hazardous events while a particular ship is under operation. Hazard analysis is the process of recognising hazards that may arise from a system or its environment, documenting their unwanted consequences and analysing their potential causes. It is the process of describing in detail the hazards and accidents associated with a system, defining accident sequences and identifying hazards through a systematic hazard analysis process. Two of such processes are HAZOP and HAZID. Our focus will be on Hazard Identification (HAZID). Here the area of interest is to have a task following the context Operations and management of hazard analysis since there is a huge number of passenger vessels, cargo vessels and oil tankers are operating through local routes in our country without having proper knowledge of possible hazardous events that may arise during operation.

2016 – 2019	Systems-Theoretic Approach to Safety of Inland Passenger Vessel Operation in Bangladesh An Accident model should include processes, social systems (organisation and manage4ment) and technology; not simply events and conditions. The most basic concept in STAMP (Systems Theoretic Accident Model & Processes) accident model is a constraint, rather than an event. Using this model, accidents can be understood in terms of why the controls that were in place did not prevent or detect maladaptive changes i.e. by identifying safety constraints that were inadequate in enforcing them. This model includes Entire socio-technical system (not just technical part), software and system design errors, component interaction accidents and human errors. The objective of this project is to analyse and prevent the maritime accidents of Bangladesh by applying STAMP. All the regulatory bodies and enforcing authorities relevant to the maritime safety sector of Bangladesh are taken into consideration by applying feedback loops in the STAMP model.

2016 – 2021	Development of a Mathematical Model for Ship Repair Time Estimates This research focuses on the estimation of the required docking time for a particular type of ship on the basis of ship repairing parameters. Dry-docking of ships are part of manufacturing and production processes incorporating hull inspection, plating works, sandblasting, painting, tank cleaning works, and others. Ship docking time indicates the duration of stay of a ship in a dockyard/shipyard (also a slip way or floating dock) and receives maintenance services, so that the ships can be operated profitably and be kept in the proper condition in line with the regulations of IMO (International Maritime Organization), flag States requirements and standards of Classification Societies. The independent variables that control the ship repairing time (which is the dependent variable) will be identified. A multiple linear regression model will be developed. The method of least square will be applied to evaluate the regression coefficients. It is believed that this model may support the management to estimate repairing time for providing better service, which eventually will boost the economic growth of Bangladesh and eliminate poverty.

2005	Effect of Bulbous Bow on Motion of Ship It is quite a common phenomenon that ships have bulbous bows these days. The reason is mainly savings in fuel consumption and occasionally added buoyancy. Fuller vessels are quite efficiently using this technology. But it’s effect on finer vessels particularly faster vessels are not much known and understood. Therefore, this project puts light upon finding motion response of a finer vessel (Series 60, Cb = 0.6) incorporating different types of bulbous bows. Different types of bulbous bows have been designed in three-dimensional (3D) computer aided design (CAD) software. The vessels with their new bows were paneled. A C++ computer program is developed for this paneling purpose. With these new designed bulbous bows the motion characteristics are studied using 3-D source distribution technique in regular wave. Since the research project is in the early stage, no conclusion can be easily drawn. But based on the available research findings, it is evident that bulbous bows influence the amplitude of motions, particularly in the region of natural frequency.	Professor Dr. M.
