Modeling offshore wind installation vessel day-rates in the United States

摘要: Marine vessels used to install the foundations and turbines at offshore wind farms are currently a small specialized fleet located exclusively in Europe where significant development has occurred over last decade. The costs US developer lease an installation vessel subject large degree of uncertainty because supply demand conditions, willingness pay regulatory requirements. purpose this article is estimate day-rates for between 2012–2017. Three model frameworks developed using capital cost model, leasing strategy developer-owned strategy. Transport parameterized create estimates total by type mobilization distance. Day-rates liftboats, jack-up barges self-propelled expected range 12 500 75 000 US$/day, 25 000 150 000 $/day 60 000 300 000 $/day, respectively, time period considered.
