The WTS has been developed to install offshore wind turbines. Unlike other installation vessels, the WTS has a small waterplane area twin hull (SWATH) design.

The vessel is capable of transporting and installing two fully assembled wind turbines or two wind turbine foundations; it features a dynamic positioning system and wind turbine hoist tackles that are equipped with an active system to compensate for the heave motion of the vessel.
