WE WILL PARTICIPATE IN:

solar-energy

For 2019 our team decided to participate in the Monaco Solar & Energy Boat Challenge 2019. Our top priority was to find and construct the best design for the cockpit, alongside with the use of renewable energy sources,such as solar cells. We then, developed an energy management system, supporting the aim of green shipping using solar panels. In addition, we developed optimised propellers and constructed our cockpit using carbon fiber.

OUR RESEARCH:

Design:

  • Design and comparison of the advantages of various designs for the cockpit,aiming to find out the most efficient geometry.
  • Thorough Study of wave piercing bows and a streamline superstructure
  • Research and design of  the steering wheel and the mechanism of the rudder, as well as the mechanism of the power transmission from the electric motor to the propeller.

Construction:

  • Researching and examining the final construction of our model ship and the parts included.
  • Study on the ship’s durability determining which materials should be used
  • Selection of Carbon Fiber,Glass Fiber, Wood, Foam, Resin,as the optimized materials

Propulsion:

  • Testing of various propeller geometries, both in theory and in practice.
  • Designing the propulsion system for the vessel prototypes, i.e. the construction of the propellers with 3D-printing methods and devising an energy management plan, especially for the long distance race in collaboration with the Electronics team.

Electronics:

  • Development of a live telemetry data flow for the course of our boat such as velocity, rpm, pitch, energy consumed, energy remaining, in which we will have access via computer or tablet.

2018 – 2019 TIMELINE:

  • Oct 2019

    Recruitment

    Our decision to participate in the Solar and Energy Boat Challenge redefined our existing goals while setting new ones. Oceanos reorganized its team,selected a new Team manager Team coordinators. Later that month, a recruitment process was carried out not only to fill the void in the team but mostly to offer other students the opportunity to get involved, participate and acquire new knowledge and experience.

  • Nov 2018

    Cockpits’ Design

    The preliminary and the most important part of the design was to study and compare the advantages of different designs regarding the cockpit. Thus, our team examined different  concepts in an effort to figure out what could be the most efficient geometry. Wave piercing bows and a streamline superstructure are some of the concepts that were analyzed
    subsequently.

  • Dec 2019

    Final Design

    Soon after we determined the basic dimensions of the cockpit, we created drawings in Rhino3D. In collaboration with the structural team, we detected some expected problems due to overweight and thus, the first design was optimized. Meanwhile, we designed the steering wheel and the mechanism of the rudder, as well as the mechanism of the power transmission from the electric motor to the propeller, by conducting a research in several similar designs and through the information the propulsion team had gathered beforehand.

    Electronics’ Research

    For the energy class competition our electronics team we focused on the development and construction of a storage and propulsion system which solely utilized solar power. A photovoltaic generating system, that will track the sun position, were used as the charging source for multiple Lithium-Ion battery banks during the race. The stored electrical energy was then used to provide electric autonomy for the vessel. Furthermore for this reason an intelligent energy management system was adopted to control the charging and discharging current flow of the batteries.To achieve telemetry and constant communication between the driver and the team ashore ,a combination of sensors and microprocessors were used to transmit all vital information from the vessel to the shore and the other way around.

    Resistance Test

    After the hulls  were completed and well-connected to each other, the experimental process  commenced by measuring the resistance curve in calm water.Typically, the ship’s cruising speed assessment process begins with a bare hull resistance experiment.The next step is to perform self-propelling experiments to fully investigate the hydrodynamic behavior of the vessel and calculate the cruising speed.In the case of the experimental procedures above, after we estimated the equipment’s weight to be used, we decided to carry out the 40kg displacement experiments, a displacement which later, was chosen to be the final weight of the vessel.

  • Apr 2019

    Propeller's Construction

    We  constructed the propellers with 3D-printing methods and an energy
    management plan especially for the long distance race in collaboration with the Electronics team.Desinging wake adapted propellers for each race based on systematic series and modern literature. Towing tank experiments of vessel models or CFD simulations provided the required data for such an operation. The software used has been developed by the Laboratory of Ship and Marine Hydrodynamics (LSMH) at NTUA.After the Electronics team,provided us with experimental results of the battery and motor operational curves, data that serve as constraints in our design. Endurance estimations for the long-distance race were made at this phase. We  manufactured prototypes with 3D-printing additive methods and various materials. The performance of the prototypes were investigated in open water experiments and the final selection were made based on additional sea trials.
