In Accordance with API Cat III & Cat IV
Importance of Rig Inspection
Drilling rigs are complex systems with various components working in tandem. Rigorous inspection is essential to identify potential issues, enhance safety, and ensure compliance with API Category III and IV standards.
Our Rig Inspection Process
Our experienced inspectors follow a meticulous rig inspection process:
-
Structural Inspection: Thorough examination of the rig's structural components to identify any signs of wear, corrosion, or fatigue.
-
Mechanical Systems Inspection: Comprehensive assessment of mechanical systems, including engines, transmissions, and hydraulic systems, to ensure optimal functionality.
-
Electrical Systems Inspection: Examination of electrical components and systems to verify safety and compliance with API standards.
-
Categorization: Rigorous categorization of inspection findings based on API Category III and IV criteria.
Compliance with API Category III & IV
Our drilling rig inspection services strictly adhere to API Category III and IV standards, ensuring that your rig meets the industry's highest criteria for safety and reliability.
About API Category III & IV
API RP 4G provides guidelines and establishes recommended procedures for inspection, maintenance, and repair of items for drilling and well servicing structures, in order to maintain the serviceability of this equipment.
Category III
A thorough visual inspection of all load bearing components and members shall be conducted to determine the condition of the mast/derrick or substructure, or both, and documented on the checklist. Inspections on well servicing, truck or trailer mounted masts should include observation of rig up/rig down operations.
Inspection results from Category Ill inspections shall be documented and maintained in the permanent rig file.
The two inspection category we provide explained as follow:
Category IV
A Category IV inspection shall include the requirements of a Category Ill inspection and the following requirements:
- Critical joints shall be subject to non-destructive examination.
- All equipment shall be disassembled and cleaned to the extent necessary to conduct NDT of all defined critical areas.
- All welds (100 %) shall be visually examined.
- All welds in critical areas shall be inspected using magnetic particle inspection (MPI/MT), liquid penetrant (PT), radiographic testing (RT), or ultrasonic testing (UT) in accordance with AWS D1.1. Eddy current inspection is an accepted alternative method to inspect welds in critical areas. A MPI/PT method shall be used to evaluate indications identified with eddy current. Welds on galvanized structures may require different inspection techniques and intervals. Cracks are generally identified through visual inspection on a galvanized mast/derrick.
- An ultrasonic thickness test or other recognized method shall be used to test for internal corrosion on tubular members used as primary load carrying components. Internal cameras, usually run on cable, may also be used to visually inspect for internal corrosion.
Inspection results from Category IV inspections shall be documented and maintained in the permanent rig file.
Our Inspectors are qualified to the API Approved Training for API 4G Drilling Structure Inspections.
