DISSERTATION

Module Grade: 74%

For my dissertation I wanted to focus on renewable energy and develop ideas to encourage a greener future. I created a web-based tool using html, css, javascript and qgis which determines floating offshore wind turbine output (MWh/year) from a selected place around the UK. The aim of the tool was to prove that floating offshore turbines are much more efficient than fixed offshore turbines and other current commonly used methods.

Shapefile

Using QGIS, I used a shapefile resource found from an online source displaying offshore windspeeds around the UK. This was then further used for calculations in the backend server to determine overall power output of turbines. As seen by the colours in the shapefile, the further out at sea the more red/dark the location (higher windspeeds).

Turbine Models

Using the Weibull distribution for the calculations, I was able to use a source showing model curves to calculate speeds for multiple turbine models. This gives the user a more specific idea of how much energy can be generated.

Main Advantages of Floating Offshore-Turbines

Expected reductions in Fracking and other non-renewable energy.

Higher energy generated per module in comparison to on-shore and off-shore fixed turbines

Less sight and noise pollution due to the turbines being far away from land.

Overall Results

The plotted table displays a side-by-side comparison of the results achieved from both selected locations with each turbine model represented as its own row. As seen by the difference, deploying floating turbines out at sea rather than fixed and floating turbines closer to shore, a much higher amount of energy can be generated each year, more than double in most of these cases.
