Derrick and Bolt Inspection
Masts and derricks support enormous loads when drilling and running casing. API-4G recommended practice for mast and derrick inspections is a critical element to avoiding potentially non-productive time loss, or even serious incidents and catastrophic events during drilling operations.
Our Derrick Inspectors are IRATA-qualified rope access technicians with a background in maintenance, and able to access normally non accessible areas for routine inspection companies, and we reduce defaults, by carrying out as many repairs as allowed by the time within the survey period. The bolt inspection consists in 20% of bolt torque check, and 100% of Visual Inspection.
