Offshore wind energy has emerged as a major frontline competitor for producing sustainable and carbon free energy. With the recent advancement in engineering the researchers and developers are challenging the conventional wisdom of existing technology to improve the economics of wind power. Offshore wind turbines are rated in megawatts (MW) and costs approximately $1.5 million per MW for an installed capacity of 5 MW. On an average basis 5% to 15 % of this total capital investment goes into transportation and installation which is basically due to high day rates of jack up barges and other dynamic position vessels. An innovative floater conceived and designed by Nagan Srinivasan wherein the concept of self installation is introduced has been undertaken for hydrodynamic analysis during the transition phase in this study. Analysis has been carried out for different drafts and statistics of responses summarized for seastate 5. © 2014: The Royal Institution of Naval Architects and IIT Madras.
