This is the case for many notable large continue the momentum of its development, the offshore wind projects such as Horns Rev, London Array, Gemini Wind Farm industry is looking to continually lower the levelized cost of and Dudgeon. electricity (LCOE). One area being explored in an effort to lower Wind farm designers have considered the value of the LCOE of offshore wind generation is the optimization of the minimizing wake effects, as the rows and columns of wind wind farm layout. Many of the offshore wind farm layout designs that exist today are structured in a rectilinear form where turbines farms are often oriented into an optimal direction based on the are spaced evenly along columns and rows. This thesis explores the local wind climate. However, the inconsistent nature of economic advantages of removing rectilinear constraints and environmental factors such as the local wind climate, optimizing the positions of the individual turbines within an bathymetry, and soil types would conclude that these are not offshore wind farm. driving factors in the structured layouts. At the core of achieving the thesis objective was the development It has been hypothesized through many academic research of a model that is capable of simulating an existing offshore wind efforts that keeping rectilinear formats may cost a great deal farm by converting representative wind farm data into an LCOE.

Operation & Maintenance (O&M) makes up a significant part of the overall cost of running offshore wind turbines. The complication of O&M lies in that its responsibility has been split between turbine manufacturers, wind farm operators and the offshore transmission owners.
