Abstract: A method of assembling and deploying a floating offshore wind turbine (FOWT) platform includes floating a buoyant floater and a hollow outer tank in a floating assembly, placing permanent ballast material in the outer tank to define a mass, and sinking the mass to a seabed. The buoyant floater is moved to a position over the mass. Transit lines are attached between a lifting device in the buoyant floater and the mass to define a FOWT platform. The mass is lifted to a point directly under the buoyant floater and the FOWT platform is towed to an installation site. Mooring lines are attached between anchors in the seabed and the buoyant floater, and the mass is lowered to a depth wherein suspension lines attached thereto are taught, the mass with the suspension lines defining a suspended mass. The transit lines are then stored or removed from the mass.
