Driven by unwavering determination, the Néréides team aims to push the boundaries of sustainable innovation and advance marine technology. Bringing together a diversity of skills, experiences, and expertise, the Néréides team is poised to take on the challenge of the Monaco Energy Boat Challenge for a second time.

project

For this edition, we aim to be able to control our propulsion system completely. Therefore, we intend to assemble our own system. With the assistance of a naval architect, we have studied all possible configurations (two engines, one engine, front, rear, etc.). We have chosen a single engine positioned at the stern.

The calculations undertaken considered the geometry and water resistance on the hull. The calculations followed the procedure proposed by Carlton in the book “Marine Propellers and Propulsion.” This procedure was able to determine an ideal propeller geometry and the necessary power, torque, and rotation for the expected operation. The propeller will be placed ahead of the pod to prevent the water from being diverted.

We’ve selected an electric outboard motor with an electrical power of 12 kW.

project

This time the propulsion system strives for a strategic performance. The power consumption can be adjusted to the requirement, using 3 preset modes which limits the energy usage, Eco-Mode will be opted for endurance race where efficiency is vital and for high performance the sports mode will be opted while normal mode is optimized for cruising.

Two 6500 W propulsion systems with MOX-09 motors are rated at IE5, this is the world’s highest energy efficiency classification for electric motors. The manoeuvrability of the boat through thrust vectoring, expands the YALI’s ability to take agile turns. The twin Propulsion System produces 1668 Newtons of thrust. Decreasing propeller diameter achieves 40% more acceleration and 15% drag reduction.

The YALI cruises at a speed of 18 Knots and reaches a top speed of 25 knots. This time we’ve opted for a Magnetic propulsion, eliminating energy loss due to water seepage. The anti-ventilation plates above the propeller restricts the flow of air into the propeller preventing loss of traction and reduces slip.

To optimize the efficiency sinewave technology has been employed, where the controller manages the heat produced inside the system which increases the performance, efficiency and provides longer life to the motor and the controller of the propulsion system.

project

The objectives for the propulsion systems are mainly twofold: the first concerns the propeller, and the second pertains to the electric powertrain. Our goal is to enhance the propulsion systems by incorporating two distinct types of propellers, one optimized for endurance races and another tailored for the remaining races.These propellers will be produced by using 3D printing technology. Additionally, we are addressing ventilation concerns from the previous year by developing a new “anti-ventilation” plate. On the electrical front, our focus lies in refining the motor inverter software. We aim to implement a sensorless controller for our electric motor to improve energy efficiency. Moreover, we are exploring the feasibility of increasing the quantity of photovoltaic (PV) panels on board to recharge the batteries during the endurance race.

Team

The Hydrovinci association is centred on naval construction. It is through working in this sector that the association helps 68 students from the three schools to develop their competences.
The main goal of the association is to optimise the energy efficiency of sea-going craft.
After 4 years of competing in the MEBC, the association has entered the Hydrogen era. It is with 28 students from the engineering school that the team will try to improve the results from last year.

project

This year, we plan to improve greatly the boat embedded system.

The first choice we made was to downsize the onboard-computer. The previous year, this function was fulfilled by a Raspberry Pi 2B, which included a 900MHz quad-core CPU with 1GB RAM and was capable of performing complex graphic calculations, processing video and even running games. All of those capabilities are far overkill for the intended usage of the system.

So, in an attempt to better suit the needs of the Monaco Energy Boat Challenge, we decided to downgrade the system hardware and use a Raspberry Pi Pico with a 133MHz Dual-core processor and 264kB RAM which is more energy-thrifty and better fits the project needs.

Team

UniBoAT is an innovative teaching and research project born inside the Industrial Engineering Department of the Alma Mater Studiorum University of Bologna in October 2019. The team is devoted to the development and implementation of an eco-friendly and fully electric boat, through sustainable solutions. We are participating for the fourth time as an emblem and demonstration of our efforts into developing and improving this field of research.

project

Another fundamental component of the powertrain is the battery. The construction of the two home-made batteries is a focused effort emphasizing the creation of the most efficient setup tailored to our specific needs. Our Battery Management System (BMS) is also a product of our own design and construction. Prospective upgrades may involve the construction of new batteries to reach highest peak performance. Furthermore, a fuel cell is integrated to convert the hydrogen stored in the cylinders at 200 bars into electricity; this generated power will recharge our batteries during the endurance race, allowing us to utilize hydrogen as an additional energy source, like the approach employed last year. Acquiring a completely new fuel cell is under consideration, given the advancements in Proton Exchange Membrane (PEM) technologies. Finally, for weight reasons the photovoltaic panels will be removed which means that we will only use two energy sources and not three.

Our objectives extend beyond competition, focusing on the broader impact of green energy and contributing to a more sustainable future.

project

Hydrodynamics and Propulsion Team are responsible for the motion transmission and the conversion of battery energy to thrust.Last year the attention of the team was more oriented towards the pod. Specifically tests and experiments were conducted to ensure not only it’s durability and robustness, but also that is going to reach the highest performance possible concerning the efficiency of the propulsion system. As a result, this year hydrodynamics and propulsion team is aiming at the optimization of the propellers. This is going to be achieved by choosing a better type of propellers that fits our needs and adjusting the basic parameters of the propeller such as the diameter, pitch, and rake. However, our propulsion system consists of contra rotating propellers and its optimization is way more challenging and its complexity is further increased because the hydrodynamic relation between the aft and forward propeller should be taken into consideration. Consequently, the following question emerges. How the targets above are going to be achieved?

project

The planned propulsion system consists of a 10kW electric motor powered by a Lithium-Ion battery pack and a hydrogen PEM (Proton Exchange Membrane) Fuel Cell. The motor will mount custom-designed 3D printed propellers. We also developed a new transmission for contra-rotating propellers. We will proceed with thorough testing to validate this design to evaluate its performance and its mounting it on our propulsion system will be fruitful or not. In parallel to these developments, the team is currently designing the transmission, pod and casing for a new custom outboard motor.

Polytechnique de Montréal

Team

Our team was formed in December 2019 with the goal of participating in the Monaco Energy Boat Challenge and has expanded considerably since our first participation in 2022. Due to the added complexity of a 100% hydrogen system, we took two years to complete our new system. We are aiming to participate in the 2024 edition of the challenge in the Energy class. With a completely redesigned energy system and many structural and electronic improvements, we believe that we are ready to step up from our first participation and bring a challenge to the other teams.

project

The last edition of our boat was powered by a Li-ion battery. This year, every part of the propulsion system has been redesigned to welcome our new hydrogen Fuel cells. Our boat will be completely powered by the hydrogen fuel cell with the aim of avoiding adding weight with a large battery. This transition from a 100% Li-ion to 100% hydrogen makes it necessary to also add a controlled high- and low-pressure gases system and a batch of 4 cylinders. From last edition, we also changed or 4kW motor to a 5kW motor. With this new propulsion system and this new motor, we are looking to improve our races performance. In our first year we also noticed that the motor was not deep enough under water. We then proceeded to add a lowering system allowing us to get the motor down when in the water, but that we also can get back up when on shore.

The Messina Energy Boat team is made up of students from different
master’s and bachelor’s degree courses at the University and it will be the team’s second participation in the competition. The passion for the sea and new technologies related to boating are the foundations that the team has been following for the past two years to improve their boat.

project

We decided to improve and optimize our engine from the previous configuration, carrying out various modifications and improvements:
• replacing the old stem with a longer one to have deeper immersion in the water and therefore a more regular thrust trajectory, facilitating movements.
• using a new performant engine bracket which allows us to minimize the friction with the water and assure different mounting positions of the engine. The new bracket indeed is able to change tilt and trim angles, allowing us to reach maximum efficiency of the propulsion system reducing consumption
• concerning the speed control system, we decided to equip a single throttle avoiding the pedal to improve the control of the boat especially during the Endurance Race and in rough sea conditions
• providing multiple lightweight solar panels which increase the traction battery range.
