The contemporary world is reaching a point of having to look back carefully to reevaluate the damage that has been done to Mother Nature. The increasing pollution and contamination have gotten far beyond safe margins. In contrast, the need for energy is currently escalating. Meanwhile, traditional energy resources like petrol are not only adding to pollution but even are getting consumed and expected to be scarce within decades. Consequently, nations worldwide have realized the common goal of searching for new clean renewable energy resources. It is a matter of time that these renewable energy sources will prevail and become the main sources. The most effective resource of renewable energies is wind. This is attributed to consistent availability in many spots worldwide. Offshore areas may be the best for higher wind momentum. Besides, the escalating land prices redirected experts to vast offshore areas. On putting economic costs into account, an optimized design is thus required to minimize the cost of offshore wind farms together with considering efficiency. Wind turbines can be classified according to number of rotors, Single-Rotor Wind Turbine (SRWT) and Multi-Rotors Wind Turbine (MRWT). This paper compares from a stability-wise scope between existing models of offshore SRWT and MRWT, both with total capacity of 5MW using ANSYS software. Both turbines are considered subjected to similar conditions of wind and wave loads. On studying the stability of the two types together with accounting for costs and investigating comparable loads during storms with extreme conditions, it is shown that MRWT are locally subjected to higher deflections in the rotor fixation spars. However, MRWT could be cheaper as well as easier for transportation. This paper suggests using additional bracing between spars for optimum performance of MRWT and thereby optimum design of wind farms.
