ABSTRACT:
A compliant offshore structure with flex tubes that are not driven into the sea bottom. A foundation template has bottles with skirt pile sleeves and a closed bottom socket. A tower and tower extension support the deck above the water line. The tower legs each enclose a flex tube such that there is an annulus between the leg and flex tube. The flex tube extends below the lower end of the leg so as to be received in the socket. The flex tubes are grouted in place in the sockets to connect the tower to the foundation template. Thickened wall portions may be provided on corresponding sections of the leg and flex tube to provide wear surfaces.
