Project Description

Floating offshore wind turbines (FOWT) are widely seen as an essential part of many countries’ drive to achieve ‘net-zero’. However, the Levelised Cost of Energy of FOWT is still high compared with fixed foundation offshore wind, and therefore additional innovation is needed.

Scaled physical modelling of FOWT is a critical stage in the development of new design innovations, but represents a significant challenge. Hydrodynamic loads applied to platform and moorings from waves and currents are modelled in wave tanks, such as the COAST laboratory’s Ocean Basin. However, aerodynamic loads also have a significant influence on the FOWT system’s response and cannot be ignored. The application of these aerodynamic loads without introducing unwanted scale effects to the experiment represents a significant challenge.

This PhD will explore the use of two techniques for overcoming this challenge, to enable the testing of high capacity FOWT. The first technique involves the wind turbine being replaced with thrusters which apply correctly scaled aerodynamic loads to the floating platform. The generated loads are controlled in real time using a surrogate model ‘trained’ using results from more complex numerical models. In the second approach COAST’s new 3 m x 2.8 m wind generator will be used to generate a wind field over the Ocean Basin. A model turbine will be installed on the scaled floating platform to generate the aerodynamic loads.      

Supported by the ORE Catapult, the successful candidate will gain skills in both state of the art physical and numerical modelling of FOWT. It is envisioned that the student will work with industry partners to support their physical modelling within the COAST laboratory.

Eligibility

Applicants should have a first or upper second class honours degree in an appropriate subject and preferably a relevant Masters qualification.

The studentship is supported for 3 years and includes full Home tuition fees plus a stipend of £17,668.00 per annum (2022/23 rate).  The studentship will only fully fund those applicants who are eligible for Home fees with relevant qualifications.  Applicants normally required to cover International fees will have to cover the difference between the Home and the International tuition fee rates (approximately £12,670 per annum).
