Artemis-PSR or Artemis Pile Scanning Robot is a semi-autonomous device for the acquisition of wall thickness measurements and other information relating to structural integrity of a marine pile. Artemis-PSR scans the entire length of the pile providing engineers and asset owners with far greater information than manual testing methods. Artemis-PSR uses several non-destructive testing (NDT) technologies such as laser, ultrasonic and electromagnetic testing to enhance accuracy.
