Abstract: A method of repairing a turbine engine component involves offering two repair options to a customer. A first repair option is based on an operating environment of the turbine engine component and the second repair option is based on cost. The first repair option is priced higher than the second repair option. The turbine engine component is examined. The turbine engine component is then repaired according to the selected repair option.

Abstract: An optical fiber pH sensor 100, 200, 300 is described, where a transducer mechanically couples a Bragg grating to a pH-sensitive hydrogel, said sensor comprising a central part 110, 210, 301 where are placed the optical fiber 121 containing a Bragg grating 122, the pH-sensitive hydrogel set of discs 130, and the mechanical transducer which is a spring 123 a beam 215 or still the optical fiber itself 121, the mechanical transducer assuring the strain on the Bragg grating 122. The change in hydrogel hydrodynamic volume resulting from a change of the pH of the medium introduces a force that is sufficient to cause a strain in the Bragg grating. The measure of the pH change is retrieved using the usual techniques for wavelength measurement. The pH sensor 100, 200, 300 of the invention is useful for the indirect evaluation and control of corrosion in petroleum wells and is suitable for multiplexing with other optical fiber sensors measuring the same or different parameters.

Abstract: An electrical power outlet assembly having a housing supporting a plurality of electrical outlets each including an electrical plug receptacle. One of the outlets defines a pocket containing a portion of the casing of a field replaceable transient voltage surge suppression module (TVSS). The TVSS module is supported on the outlet assembly housing in plugging engagement with the plug receptacle of the one outlet which defines the pocket.
