By systematically dividing a derrick into small, manageable sectors, Vertech ensures that all sections are examined in detail and received a fully-focused inspection.
Because our inspectors are Rope Access-qualified they are able to conduct a thorough, close visual inspection of the derrick structure. This detailed inspection process covers:
