API standards for rig inspections:

• API RP 4G: Outlines recommended practices and procedures for inspecting, maintaining, and repairing drilling and well-servicing structures (e.g., masts, derricks, and substructures).  

• API RP 8B: Defines procedures for the inspection, maintenance, and repair of hoisting equipment like traveling blocks, hooks, and elevators. 

• API RP 7G-2: Specifies the required inspection levels, procedures, and testing for used drill stem elements, including drill pipe bodies and tool joints. 

• API Spec 16A: Focuses on the design, manufacturing, and testing of well control equipment, including Blowout Preventers (BOPs).

​

Categorized Inspection Scopes

• API categorizes structural inspections into four levels, which increase in intensity, dismantling requirements, and frequency:

• Category I: Visual observation of equipment while in use by the rig crew to identify obvious defects.  

• Category II: More thorough visual inspection including cleaning, covering exposed areas, and checking specific non-destructive testing (NDT) areas. 

• Category III: Visual and NDT of critical load-bearing components. Requires partial dismantling to access hidden or high-stress areas.  

• Category IV: Complete disassembly of structures. Extensive NDT is conducted on all primary load paths to verify the absolute integrity of the rig.  ​

In-Country Value (ICV) requirements are primarily mandated by governments and major national corporations in the Middle East. These programs are designed to localize supply chains, boost local spending, and create private-sector jobs.  

​

The following countries formally require or utilize ICV certification for government and enterprise contracting:

• United Arab Emirates (UAE): The UAE has a National In-Country Value Program (ICV) - MOIAT overseen by the Ministry of Industry and Advanced Technology (MoIAT). It is required to win tenders with government and semi-government entities (such as ADNOC).  

• Qatar: Managed through a centralized In-Country Value Digital Portal, Qatar implements strict ICV scorecard policies that directly impact the commercial evaluation of tenders. 

• Oman: Oman has been a pioneer in ICV policies, particularly within the oil and gas sectors (like Petroleum Development Oman) to boost "Omanisation" and local procurement.  

• Saudi Arabia: Through the In-Kingdom Total Value Add (IKTVA) program (heavily championed by Saudi Aramco), the Kingdom requires suppliers to demonstrate their local economic contribution.
