Udemy – Overpressure Protection

Overpressure Protection Training Course provided by Velocis Solutions aims to deliver comprehensive information about the possible overpressure scenarios and protection systems to tackle the problem. Overpressure is the pressure increase above the set pressure necessary for the safety valve to achieve full lift and capacity. The overpressure is usually expressed as a percentage of the set pressure. Codes and standards provide limits for the maximum overpressure. The relief system documentation should demonstrate that all pressure-containing equipment has been identified and the relief requirements analyzed. Documentation based on the protected systems can help ensure that all systems requiring pressure protection have been identified and documentation should show that potential causes of overpressure have been identified, rationale has been provided as to whether a scenario is or is not credible, and credible causes of overpressure have been evaluated.

The course takers can take the huge benefits of the training course which comprises the best practical knowledge and was proposed by referring to API standards. The following topics are discussed throughout the course to deliver valuable source of information to course takers:

Introduction to the course and documentation
