Comprehensive periodic surveys for rig safety

At Control Union, we recognize the critical importance of maintaining the integrity and safety of drilling and well servicing structures. Our expert inspectors are equipped to perform complete category III or IV inspections on drilling and well servicing structures (derrick and substructures), in accordance with the industry-respected API Recommended Practice 4G. With a focus on thoroughness and adherence to regulatory standards, we ensure that your structure operates at its best while minimizing potential risks.

Visual inspection covering all components

Our dedicated team conducts meticulous visual inspections that encompass every aspect of the structure. This includes a comprehensive evaluation of the derrick legs, as well as an assessment of structural beams, various pad eyes, ladders, platforms, etc. By scrutinizing these critical components, we identify any potential issues or areas that may require attention, maintenance or repair, allowing you to address them proactively.

Optional bolt tension checks and torquing

As part of our rig audit services, Control Union offers the option to include bolt tension checks or torquing in the derrick survey if necessary. This additional step ensures that the fastening elements of the derrick are properly tightened and secure, further enhancing its structural integrity and overall safety of the structure.

DROPS survey integration

To provide a comprehensive assessment, we offer the option to combine the survey with a DROPS (Dropped Objects Prevention Scheme) survey. This integration allows us to evaluate potential hazards related to dropped objects and implement preventive measures effectively, further enhancing the overall safety of the structure and its surroundings.

To cater to the unique challenges of inaccessible areas, we provide rope access trained inspectors who are certified to IRATA or equivalent standards.
