What is BS EN ISO 13626:2015?

BS EN ISO 13626:2015 is a technical standard that provides guidelines for the design, selection, and application of subsea wellheads and associated equipment used in offshore oil and gas drilling operations. It was developed by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN).

Key Requirements of BS EN ISO 13626:2015

The standard outlines various requirements to ensure the integrity, safety, and reliability of subsea wellheads. These requirements cover the design, materials, installation, testing, and maintenance of the equipment. The main objectives of BS EN ISO 13626:2015 include preventing blowouts, ensuring effective sealing mechanisms, and enabling efficient well control.

Design and Selection of Subsea Wellheads

This section of the standard focuses on the design considerations for subsea wellheads, including their structural integrity, load capacity, and fatigue resistance. It also provides guidelines for selecting suitable materials based on the operating conditions, such as water depth and temperature. The standard emphasizes the need for adequate corrosion protection and addresses the challenges posed by factors like sour gas and marine growth.

Application and Testing Procedures

BS EN ISO 13626:2015 lays down procedures for the proper installation and testing of subsea wellheads. It covers aspects like cementing, pressure testing, and monitoring of annular pressure during drilling and completion operations. The standard emphasizes the importance of regular inspections and maintenance to identify any potential issues or risks. It also provides guidelines for conducting reliability assessments and verifying the performance of the equipment.

In conclusion, BS EN ISO 13626:2015 plays a crucial role in ensuring the safety and reliability of subsea wellheads in offshore oil and gas operations. By complying with the standard's requirements, companies can mitigate risks, prevent accidents, and enhance the overall efficiency of drilling operations.
