    FAQ

    Frequently asked questions

    Clear and concise answers to common questions about our rig inspection and acceptance services, ensuring compliance, safety, and operational readiness.

    Ask our team

    We provide full rig inspection and acceptance services, including pre-acceptance, acceptance, and commissioning inspections for drilling and workover rigs. 

     Our inspections are performed in accordance with international standards such as IADC, API, OEM specifications, and client-specific requirements.

     We inspect all major rig systems including hoisting, rotary, mud, power generation, control systems, BOPs, and safety equipment.

    Rig inspection ensures equipment integrity, regulatory compliance, and readiness for operations, reducing HSE risks, non-productive time (NPT), and startup delays. 

    Deliverables include detailed inspection reports, compliance checklists, punch lists, acceptance certificates, and clear recommendations for corrective actions.
