STUDENT PRESENTATIONS TOPICS INCLUDE:MIDN Jack Drow 1/C, MIDN and Kevin Stefanick 1/C,Advisor: Dr. James Garofalo, USMMATitle: “Design and Testing of Autonomous Drone for Man-Overboard Scenarios”This project tests the feasibility of utilizing an Unmanned Aerial Vehicle (UAV) for Marine Man-Overboard (MOB) Search and Rescue (SAR) scenarios. A quadcopter UAV was built, tested, and paired with a thermal imaging camera. Thermal imaging data was collected and used to train a real-time object detection algorithm using Artificial Intelligence to locate and detect persons in the water. The results of the combination of these components were analyzed and recommendations were made for carrying out future work with this application.
First, the components to be used were researched and chosen. UAV components were purchased and the UAV constructed. Flight tests were then performed in order to ensure that we would be able to have controlled and stable flights.
The Flir Vue Pro thermal camera was chosen and tests were performed with the camera so that a preferred camera setting could be decided. Once the optimal camera settings were chosen, data was collected and annotated for use in training the detection algorithm. The algorithm used was YOLOv5 from Ultralytics. This state-of-the-art algorithm allows for real-time object detection and tracking, both being requirements for the successful deployment of this project. The object detection model achieved an accuracy of 75.4% in our limited use case.
Taking this project further, significant amounts of data need to be collected in every sea state, night and day, so that a detection model can be created that can find persons in the water in any situation. This project shows the feasibility of such a venture and describes what needs to be done in the future to take this project further.Kevin Stefanick – Kevin is 1/C Midshipman at the United States Merchant Marine Academy with 300 days of commercial / MSC sailing experience as an engine cadet.

The device is a 3D printed, hollow and very thick airfoil with slots running the length of the wing. The wing is connected to a shop vacuum, and a venturi tube is used to measure air flow rate. Preliminary results show a marked increase in aerodynamic lift force, as compared to without suction. The widescale use of such ship-mounted suction wings would reduce vessel fuel consumption.Carter Pomponio, Esha Talur, Liam WalkerAdvisor: Raju Datla, Stevens Institute of TechnologyTitle: “An Innovative Ocean Cleanup Hullform”A detailed study was conducted to design a vessel that will collect and remove plastic pollution and marine debris from the riverine, coastal and open ocean waters. To reduce emissions and lower the carbon footprint, the vessel will employ green energy technologies as well as other plastic processing systems both on-board and on-shore sites. Three hullforms – a small catamaran, a large catamaran and a new “split-hull” – were considered for studying the sizing, stability, powering, propulsion and the waste collection and processing capabilities of each. Based on the preliminary assessment, the hull forms were given a score for each measure of merit and an overall score was developed. Each hull form was found to have its own advantages and disadvantages depending on the operational requirements, but the new “split-hull” design was selected based on its unique features and for the need to obtain stability, resistance and seakeeping performance data for this innovative configuration. This design operates as a monohull in its transit model and splits open from a hinge point near the transom and moves at a slow speed in “collection mode”. A scale model was built and tested over a range of configurations, speeds and sea states.Carter Pomponio – Carter is a senior Naval Engineering student at Stevens Institute of Technology. He works at the Davidson Laboratory Towing Tank as a Student Research Assistant and is the Vice President of Stevens Chapter of SNAME. Carter has interned at Austal USA working on designing surface vessels. He plans to continue work in ship design after his graduation from Stevens in May of 2023.Esha Talur – Esha is a senior undergraduate Naval Engineering student at Stevens Institute of Technology. She currently works as an undergraduate research assistant at the Davidson Laboratory. She has interned at Austal USA where she worked in weights and stability and participated in the initial design stages for a new project. Moving forward Esha plans to continue a career in the naval industry and hopes to pursue forensic naval architecture in the future.Liam Walker – Liam is a senior studying Naval Engineering at Stevens Institute of Technology in Hoboken, New Jersey. He has worked in the Davidson Laboratory High Speed Towing Tank as an undergraduate assistant. This past summer he worked on the Washington Navy Yard as part of an internship program with Amentum Services working with submarine design. After graduation in May, he hopes to continue his work in the submarine industry.Katherine Mattikow, SUNY Maritime CollegeTitle: "The Use of Light Detection and Ranging for Autonomous Docking"Light Detection and Ranging technology (LIDAR) has been in use since 1961 and applied in nearly every scientific discipline– most notably in the development of autonomous vehicles. LIDAR’s successful implementation in autonomous vehicles serves as a proof of concept for its use in autonomous vessels. Autonomous vessels are in early development, but often struggle with docking and close-quarters maneuverability. In conjunction with other existing technologies, LIDAR can make the process of docking autonomous.Katherine Mattikow - Katherine is a graduate student at SUNY Maritime College pursuing a Master of Science in International Transportation and Trade with an Unlimited Deck License.

The largest problem it faces is a lack of awareness of the system architecture and a lack of knowledge among marine engineers of its benefits. This presentation proposes a high-level method of comparing medium-voltage DC systems with medium-voltage AC systems which can be accomplished during the initial concept design of a ship by a marine engineer without substantial electrical engineering background. First, a purely static analysis is conducted based on the full-load characteristics of a ship’s electrical loads. Next, operating profiles are applied to the static loads so that operation outside of the full load condition is considered. The analysis yields net fuel consumption values for each system model, which can be used as an indicator for both operating expenditures and engine emissions. It is the goal of this presentation to spread awareness of shipboard medium-voltage DC power transmission by making its consideration more approachable to ship designers.Victoria (Tori) Kim - Tori is a senior undergraduate student at Webb Institute with focuses in marine engineering and alternative energy.
