Recently Petrotek had an API audit and successfully concluded only with minor concerns.
API stands for the American Petroleum Institute, which is the industry organization that created this measure, not to mention that Petrotek is one among few companies around the world that has the four API certifications:
API Spec Q1: Specification for Quality Management System Requirements for Manufacturing Organizations for the Petroleum and Natural Gas Industry.
API Spec 4F: Specification for Drilling and Well Servicing Structures.
API Spec 7K: Specification for Drilling and Well Servicing Equipment.
API Spec 8C: Specification for Drilling and Production Hoisting Equipment.
