Assignment title: Offshore wind farm design and energy system integration
Main objectives of the assignment
To gain experience in the initial engineering design of an offshore wind farm, considering
aspects of power generation, wind loading, and monopile foundation design.
To apply your knowledge of energy supply and demand in a practical context by integrating a
new offshore wind farm into an existing energy system.
To critically reflect on the UK’s existing electricity generation mix and trends, and apply your
knowledge of energy systems to discuss the pathway towards a net zero carbon UK energy
sector by 2050.
Summary of the assignment
Several sites are being considered for a new 800 MW offshore
wind farm (OWF) in the North Sea off the coast of England (see
Appendix A). The wind farm will employ Siemens SWT-3.6-120
wind turbines (3.6 MW, 120 m rotor diameter) (Figure 1).
Depending on the site, the mean water depth is between 10
25 m. The soil at all sites is predominantly London clay
sands and gravels in the upper layers.
You are tasked with completing a two-stage
appraisal for ONE of the possible sites, as explained below.
A Siemens SWT-3.6-120
You will follow a design process (covered in the week 20 lecture and the appended PDF) to obtain
initial monopile foundation dimensions based on a maximum load assumed to occur at the rated
) when a 50-year Extreme Operating Gust (EOG) hits the rotor.
You will assess the role of the new offshore wind farm in decarbonising a hypothetical power
generation mix serving a set number of homes. Under the existing mix, these homes are supplied
by the base load from a 2 GW nuclear power plant with supply and demand otherwise being
