On the local scale, usually eight to ten large rigs are needed to deliver each commercial size turbine, in which, according to load size laws, each load is overweight and oversized (Brown). Objective: In order to close this gap, this paper aims to propose an Offshore Logistics Cost (OLC . In the past couple years, the carbon dioxide emissions solely from tower manufacturing facilities has been on a decline, with less than 20% of these emissions as a direct source from Vestas facilities. According to a previous life cycle assessment, it takes 4-7 months for a wind turbine to recover all the energy wasted throughout the life cycle of the wind turbine (Haapala et al.). Although we may think wind energy is clean, in all truth, it is not. An Integrated Monitoring System for Life-Cycle Management of Wind Turbines Kay Smarsly*1, Dietrich Hartmann2 and Kincho H.
