The criteria for the report are:
Power generation efficiency (Efficiency losses caused by dynamic wind/wave interaction) - 20pts
Structural integrity (Support structure design) - 20pts
Foundation stability (FOU - Foundations/anchors and moorings) - 20pts
Practicality of construction at full scale (T&I - Transport and Installation) - 20pts
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:
Below is a table to guide the scoring process
Points | Power | Structural | Foundation | T&I | Cost |
0 - 5 | Does not align with the wind in any conditions | ​Structural failure during T&I | ​Foundations cannot be installed | ​Installation not possible | ​Extremely over dimensioned |
6 - 9 | Sporadically aligns with wind | ​Structural failure shortly after installation | ​Foundations installed, but limited tolerance / failure shortly after installation | ​Installation possible, but poor tolerance, taking a lot of time | ​Over dimensioned with limited consideration for fabrication costs |
10 - 13 | ​Generally aligns with wind, but affected by structural dynamics | ​Structurally sound, OK built, may break in extreme conditions | ​Foundations installed, but may come loose in extreme conditions | ​Installation within reasonable timing, and okay tolerances | ​OK design with considerations for fabrication costs |
14 - 17 | ​Aligns with wind most of the time with limited effect of dynamics | ​No structural failure, well built | ​No foundation failure, well built | ​Fast installation sequence within tolerances | ​Good design at low fabrication cost |
18 - 20 | ​Always keeps in the wind with virtually no dynamic effects | ​No signs of potential structural failure, excellent built | ​No signs of potential foundation failure, excellent built | ​Very efficient transport and installation, within tolerances | ​Very efficiently designed with low fabrication cost |
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:
You can find details of the turbine using this link
We have made a 3D model (see image below) for the turbine, which can be accessed and downloaded here.
Other details:
Weight: approx. 5.5kg (centred above the tower connection)
Thrust curve shown below - tested by the Unsinkable 8 in the 2023 edition (Note: this is for the 400W model)
Yaw system included in turbine
Controller included with the turbine - note: we will connect a monitoring box instead of the controller for the competition
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.

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.
