Floating Offshore Wind Turbines (FOWTs) have low natural frequencies of motion, typically around 0.01−0.001 Hz. If external wind fluctuations match these frequencies, they can excite the motion, leading to increased loads and higher fatigue at specific locations of the wind turbine. Until now, wind turbine design has only considered high-frequency, microscale turbulence, modelled using the Mann (1994) model, as recommended by the IEC. However, this model does not capture the full energy content of the wind fluctuations around the FOWT motions natural frequencies. Syed and Mann (2024) proposed a model for these low-frequency, mesoscale fluctuations. In this thesis, the two turbulence models were implemented, combined, and input in the Siemens Gamesa Renewable Energy (SGRE) in-house servo-hydro-aeroelastic wind turbine solver for a SGRE FOWT loads simulation. The goal was to assess whether adding low-frequency turbulence increases damage on the tower bottom and mooring lines compared to using high-frequency turbulence alone. It was found that indeed for the simplified load simulations done here, the lifetime of a FOWT could be impacted by mesoscale turbulence and thus could be considered in the FOWT design.

In the last few decades, a large increase in interest in space and particularly the Moon has taken place. The Moon is seen as a gateway to the rest of the Solar System. Missions to the Moon will inevitably lead to technological and scientific advancements. These would help in humanity’s mission to explore and develop habitats in the Solar System. Companies see economic opportunities in these places for activities such as the acquisition of rare Earth materials, as well as commercialising space travel. Furthermore, countries see these accomplishments
as a sort of international competition while also collaborating with other nations. The mission design presented here aims to facilitate these objectives by providing the necessary navigation support to any future mission on or around the Moon...
