LQ: Conduct Annual Surveys
Description:
After completing this module operating personnel will be able to describe DOT regulation 192.465[a][c] regarding frequency of testing cathodically protected pipeline facilities including testing bonds. The student will describe DOT regulation 195.416[a] regarding the frequency of testing of cathodically protected buried or submerged pipeline facilities, explain DOT 195.416[j] and 195.414[c] regarding measurement of tank bottom-to-soil potentials, identify the Abnormal Operating Conditions typically associated with the conducting of annual surveys and give examples of each, and describe measurement of pipe-to-soil, tank bottom-to-soil and casing-to-soil potentials. The course will discuss (and student will learn) how to correctly take potentials readings at pipeline facilities and the electrical criteria used to determine adequate protection. The student will be able to describe and perform electrode (half-cell) maintenance, describe and perform placement of an electrode (half-cell) and use of a multi-meter while taking potential readings on a pipeline facility, define three types of foreign electrical interference: static stray current, dynamic stray current and AC induced current, describe and perform foreign line interference testing to detect interference and/or ensure electrical isolation from foreign structures in accordance with 192.473 and 192.467[f].
