Rig Inspection, Sizing and Selection

This course is intended to develop skills to conduct Inspection and Acceptance Tests on drilling and work over rigs based on API, ANSI, ISO and IADC standards through the application of check lists and procedures to verify the working conditions and readiness of major rig systems and equipment.

The course starts with a detailed description and specification of main rig systems and equipment used for drilling and work over operations and continues with the discussion of specific procedures and check lists implemented for conducting rig equipment inspection. Finalizing with a methodology used for rig sizing and selection.
