Below are some example files: Installation plan - MOZU (https://drive.google.com/file/d/1seyOquCh-OgivqZJtDaOsJHfKQJQnRus/view?usp=sharing)(2025) Risk analysis - Wind4Life ((https://drive.google.com/file/d/1wOIPsgqlQW5WCKD9-Awgv3FeTVAJgZ-V/view?usp=sharing)2025) For the Risk analysis, please follow the Kinney method and think of the risks in all of the following steps: 1. Preparation & pre-assembly 2. Transport & installation 3. Operation 4. Decomissioning

The criteria for the report are: 1. Power generation efficiency (Efficiency losses caused by dynamic wind/wave interaction) - 20pts 2. Structural integrity (Support structure design) - 20pts 3. Foundation stability (FOU - Foundations/anchors and moorings) - 20pts 4. Practicality of construction at full scale (T&I - Transport and Installation) - 20pts 5. Cost efficiency at full scale (Materials & fabrication cost) - 20pts Items 1 to 3 should be covered at prototype scale and items 4 & 5 should be covered at full scale. The small scale prototype and the full scale version should have the same design principles. To evaluate the design and costs at full scale, please use date from the 15MW NREL reference turbine and the offshore site location found here: • NREL 15MW reference turbine(https://www.nrel.gov/docs/fy20osti/75698.pdf) • Reference floating platform (https://www.nrel.gov/docs/fy20osti/76773.pdf)

Below is a table to guide the scoring process

The small scale prototype and the full scale one to evaluate cost efficiency should have the same design principles. To evaluate the design and costs at full scale, please use date from the 15MW NREL reference turbine and the offshore site location found here: - NREL 15MW reference turbine(https://www.nrel.gov/docs/fy20osti/75698.pdf) - Reference floating platform (https://www.nrel.gov/docs/fy20osti/76773.pdf)

You can find details of the turbine using this link(https://eur.vevor.com/wind-turbine-c_10731/vevor-500w-wind-turbine-generator-12v-3-blade-wind-turbine-kit-mppt-controller-p_010916952692) We have made a 3D model (see image below) for the turbine, which can be accessed and downloaded here.(https://cad.onshape.com/documents/03869c9b82c1a4c99adf3286/w/bc01671156d52435580ffe2c/e/fe8b04fb79b6df1c51899dfb?renderMode=0&uiState=68de34798e822e6713b1c4eb) https://static.wixstatic.com/media/b901e4_00bdafcc8b6748d995d810ed06e83bc4~mv2.png Other details: 1. Weight: approx. 5.5kg (centred above the tower connection) 2. Thrust curve shown below - tested by the Unsinkable 8 in the 2023 edition (Note: this is for the 400W model) 3. Yaw system included in turbine 4. Controller included with the turbine - note: we will connect a monitoring box instead of the controller for the competition https://static.wixstatic.com/media/b901e4_a3da2cef966848d88d97ea39b0557ef7~mv2.png

We cannot predict the weather for the competition day, but there are several online sources that can help you for your design. We recommend checking surf websites as they focus on the wave conditions close to the shoreline. • https://wisuki.com/

The minimum water depth will be 1m, but groups can install their structure up to a depth of 1.5m.

TBC - normally we go to a sandy beach location

We estimate that groups will need approximately 2h for installation of their structures at sea. Note that transport and installation aspects are part of the evaluation criteria, so groups with efficient procedures will gain an advantage on this aspect.

A monitoring system will need to be attached to the tower and connected to the wind turbine for each of the teams. The data is sent wirelessly to a central computer.

The tower structure is open for participants to design but the hub height needs to be 120cm ±10cm above water line.

Yes, starting with the 2025 edition we will allow for 2 turbine floater design. Note that we only supply 1 turbine to the participants who are selected for funding.
