API RP 53

API RP 53 (American Petroleum Institute Recommended Practice 53) provides guidelines for designing and maintaining blowout preventers (BOPs), critical safety devices used in drilling operations to control unexpected well pressure releases. It ensures proper equipment selection, inspection, testing, and maintenance to prevent blowouts, which can cause environmental damage and safety hazards. The standard aims to improve well control safety, operational efficiency, and regulatory compliance by establishing best practices for the equipment and procedures used during drilling and well intervention activities.
