ORCA 3500-WIND  Self Elevating Platform

With an increasing number of offshore wind installations, the need for installation and maintenance vessels has never been greater. The ORCA 3500-WIND self-propelled and self-elevating platform answers that call. A generous deck space allows for transportation and installation of two complete 4 MW turbine sets or one complete 6 MW turbine set. The equipped 600 MT main crane is capable of lifting components to the top of towers located 120m above the mean waterline, making it well suited for most wind farm developments in water depths of 50m or less.
