Wind disturbance around fixed and floating units can greatly impact the ferocity of the ocean environment.64 In order to alleviate this avoidable disturbance a series of wind tunnel tests were undertaken on a variety of different geometries so as to find the most aerodynamic form. From analysing the longitudinal and latitudinal results of five primitive geometries it can be concluded that the extended octagonal form is the most aerodynamic, due to its comparably small disturbance pattern. It was then identified that this disturbance could be further minimised by tapering the edges of this form. After comparing the efficiency of arrangement and the aerodynamic properties of the primitive geometries it was determined that a design loosely based upon an extended octagon would be the most successful when designing an efficient and comfortable floating dwelling.
