Rig mast and substructure inspections are critical safety procedures in the oil and gas drilling industry. They involve the NDT & thorough examination of the drilling rig’s mast (also known as the derrick) and its substructure, which includes the base or support structure. These inspections are essential to ensure the integrity and reliability of the equipment used in drilling operations. Several non-destructive testing ( N D T ) methods are commonly used for rig mast & substructure Inspection.
Visual Examination
Thoroughly examining the mast structure, connections, and components for any visible signs of damage, corrosion, or wear.
Non-Destructive Testing (NDT)
Using NDT techniques like ultrasonic testing, magnetic particle testing, and dye penetrant testing to identify hidden defects or cracks in critical areas.
Structural Integrity
Assessing the mast’s structural integrity to ensure it can safely support the loads and forces experienced during drilling operations.
Welding Inspection
Inspecting welds for quality and integrity, as welding plays a crucial role in the construction of the mast.
These inspections are typically conducted at periodic intervals to maintain the safety and reliability of drilling rig masts & Substructure.
