A submersible turbine assembly lift frame 7 comprises a propulsion device 22, remotely operable pitch angle adjuster 21, a remotely operable roll angle adjuster 20 and a remotely operable coupling 18 for coupling the frame to the turbine assembly. The frame may comprise a rigid rectangular framework 17 with rigid arms 19 depending therefrom. The rigid arms may have the remotely operable couplings mounted thereon. The frame may further comprise a lift cable coupling and the buoyancy of the frame may be variable. A method of using the lift frame in the retrieval of a submerged turbine assembly is also disclosed. |
