Abstract: An apparatus and method for an inspection apparatus for inspecting a component. The inspection apparatus including a robotic arm. A micro-XRF instrument having an instrument head coupled to the robotic arm. A seat supporting the component within a scanning area during inspection; and a computer in communication with the robotic arm and the micro-XRF instrument.

Abstract: A subsea assembly comprising an electric subsea machine having an electric motor driving an operator, and a coolant circuit at least partially located in thermal contact with the electric motor, the coolant circuit including a cooling assembly located externally from the subsea machine, the cooling assembly comprising at least a heat transfer element, the subsea machine and the cooling assembly being supported by a common supporting frame; at least a part of the heat transfer element is integrated in the frame.

Abstract: A method for determining a location of incipient damage of an object comprises insonifying the object at a plurality of locations using ultrasonic signals during an inspection, acquiring signals indicative of a possible damage condition from the plurality of locations of the insonified object in said inspection, determining a value for each of the locations to indicate accumulated damage by mathematically combining the acquired signals from said inspection and at least a portion of prior inspections, and comparing the values of the plurality of locations to determine a location indicating possible incipient damage.

Abstract: A method for inspecting a part is provided. The method includes immersing the part in a couplant medium, delivering ultrasonic wave energy to at least one subvolume of the part using an ultrasonic transducer immersed in the couplant medium and receiving ultrasonic wave energy from the part at a fundamental frequency and at least one harmonic frequency using an ultrasonic receiver immersed in the couplant medium. The method also includes generating a nonlinear image corresponding to at least one material property variation of the part using the received ultrasonic energy and using the nonlinear image of the part to determine whether one or more material property anomalies are present in the part.

Abstract: A method of making nano/sub-micron sized grains in a work piece material having a lateral side has the steps of providing a die. The die has an entrance channel with a longitudinal axis and an exit channel. The entrance channel and the exit channel are connected to one another to form an angle. The method has the step of providing a first sacrificial material with a complementary size to the work piece and placing the sacrificial first material and the work piece in an entrance channel. The first sacrificial material and the work piece are aligned with the longitudinal axis. The method has the step of extruding the combination of the first sacrificial material, and the work piece through the intersection of the entrance and the exit channels. The resulting shear deformation forms the nano/sub-micron sized grains in the work piece. This configuration reduces frictional effects thereby producing homogenous nano grain structure.
