Abstract: An electrochemical cell degradation monitoring method. The method includes applying first and second bias potentials to an electrode of an electrochemical cell during an operating state thereof. The method further includes measuring impedance spectra of the electrode of the electrochemical cell during the operating state biased to the first and second bias potentials. The method also includes determining a deviation in the impedance spectra at the first and second bias potentials. The method determines a degradation state of the electrode of the electrochemical cell in response to the deviation in the impedance spectra at the first and second bias potentials of the electrode of the electrochemical cell.

Abstract: A test sample is extracted from a hydrogen induced cracking (HIC) resistant material candidate. A control sample is extracted from a prequalified HIC susceptible material that is known to suffer predetermined HIC damage when subjected to preset test conditions of a standardized HIC test (e.g., NACE TM0284). The HIC test is performed on the test and control samples. A value of a predetermined cracking criteria is calculated for the control sample. It is determined whether the calculated value of the predetermined cracking criteria is at least equal to a predetermined minimum threshold value. If yes, respective values of a plurality of predetermined HIC resistance criteria for the test sample are calculated. It is determined whether the calculated respective values of the plurality of predetermined HIC resistance criteria for the test sample are not greater than corresponding predetermined maximum threshold values. If yes, the HIC resistant material candidate is qualified as a valid source for sour service applications.

Abstract: A first estimation function unit estimates, on the basis of a particle diameter of soil of a target land, a relationship between an underground depth of the land and an oxygen concentration in soil. A second estimation function unit estimates, on the basis of a corrosion rate or a corrosion amount of a target metal near a ground surface of the land and the relationship estimated by the first estimation function unit, a relationship between the underground depth and the corrosion rate or the corrosion amount in the land from a relationship between the oxygen concentration and the corrosion rate or the corrosion amount. A third estimation function unit estimates a corrosion state of a structure constituted of the metal buried in target ground in the land from the relationship estimated by the second estimation function unit.

Abstract: A corrosion detection system includes a wire disposed in a groove extending circumferentially around an exterior surface of a pipe, the pipe comprising a pipe wall and a pipe liner that lines an inside surface of the pipe wall. The corrosion detection system also includes a sensor electrically coupled to the wire. The sensor is configured to generate a voltage in the wire, and detect a change in a property of the wire caused by exposure of the wire to a corrosive fluid that is present within the pipe but outside the pipe liner.
