Abstract: A method can comprise forming a component comprising a first mating surface; coupling the component to an airfoil having a second mating surface and a Field Assisted Sintering Technology (“FAST”) system; heating, via the FAST system, the airfoil and the component; and applying, via the FAST system, a mechanical pressure between the first mating surface and the second mating surface to join the airfoil to the component and form a blade, the component at least partially defining a leading edge of the blade in response to joining the airfoil to the component

Abstract: A surface scanner for conducting non-destructive inspection of complex surface structures and configurations. The scanner includes two flexible tracks, each fitted with a motor driven tractor assembly. A rigid beam track spans the two flexible tracks. The rigid beam track is coupled to each flexible track tractor assembly by articulating joints that permit movement at the joints along at least three independent axes. The rigid beam supports a third motorized tractor. This third tractor supports a compliant thruster assembly that deploys gimbaled mechanical impedance, ultrasonic and eddy current inspection probes. The movement of the scanner is controlled by a scan control system that includes both hardware and software for controlling the movement of the scanner over the surface to be inspected.

Abstract: An apparatus and method are provided for dewatering an interior of a hollow tension leg connecting a tension leg platform to a floor of a body of water. The apparatus includes a pump having a suction inlet defined on its lower end and a discharge outlet on its upper end. An elongated storage tank is attached to the upper end of the pump above the pump and has a tank interior communicated with the discharge outlet. The assembly is lowered on an electric wireline through which power is conducted to the pump. The pump fills the tank and then the assembly is withdrawn from the tension leg and the water is drained therefrom. The assembly can be repeatedly lowered into the tension leg and withdrawn therefrom until the tension leg is substantially completely dewatered. Solid debris can be removed from the tension leg prior to dewatering.
