Maximum wind speeds have a significant influence on costs and time required for offshore wind turbine installation projects. The maximum wind speed is the speed at which it is no longer possible to lift major turbine components (nacelle, tower and blades) by a jack-up vessel. The restricting factors are crew safety and equipment damage due to instability of the load during the hoist.
Kate Freeman and I recently performed an analysis of the main factors contributing to project delays and cost increases. Importantly, we have also analysed the impact of increasing the maximum wind speed – such that lifts can be performed at higher wind speeds. We looked at the potential savings by being able to complete offshore wind turbine installation projects in higher wind speeds. Continue reading
The cost of the wind turbine installation setup is an important factor in the quest to reduce the levelised cost of energy (LCOE). Research and development within new technologies is key to making installation quicker, more reliable and safer.
But in order to fully understand the implications of reducing installation setup costs, it is necessary to perform robust calculations. And these calculations must be based on correct assumptions and figures that are as accurate as possible. Continue reading
BVG Associates has recently analysed the effects of increasing the wind speed limit for turbine component lifts. The results of this analysis are described in detail in a new report, “Impact of the Boom Lock tool on offshore wind cost of energy”.
The report, available exclusively on this site, quantifies the impact on levelised cost of energy (LCOE) of reduced vessel use and earlier power generation, based on the use of the “Boom Lock” tool.
The report concludes that reducing weather sensitivity of turbine component lifting significantly reduces LCOE. Continue reading
