Rig Inspection Course (New Course)

Date: 9-13th December | Location: Dubai

Course Duration: 5 Days

Candidates will be issued IADC certificates upon completion of course.

Course Objectives

The purpose of any rig acceptance is to ensure that the rig being hired is capable of carrying out the Drilling Programme safely, efficiently and cost-effectively. The course aims to discuss in details all the important elements relevant to rig inspection.
