Both wire rope and drilling tubulars can be inspected using Electromagnetic Flux Leakage Testing.
When visual inspections of wire rope are not enough, HADCO can perform in-service inspections of crane and mooring lines utilizing computerized dual-function units capable of measuring both localized flaws (LF) and loss of metallic area (LMA).
HADCO also uses a state-of-the-art stationary dual function VEDAQ-P unit with computerized archiving capabilities.
For on-site applications, portable dual-function (also referred to as Buggy Run) units are available. DS-1 specifies this type of unit as EMI 2.
The unit is equipped with Hall Effect Sensors that monitor changes in wall thickness and detect transverse flaws through the use of a continuous coil-induced magnetic field.
The results from each drill pipe tube are recorded on a strip chart and kept for future reference.
