Egyptian natural monopode Gas Platforms use HIPPS to protect process equipment integrity during an over-pressurisation events instead of vent stacks, which are not compatible with the platform structure. In addition, the HIPPS adoption gives a significant cost saving without any important reduction in platform safety and minimise environmental impact problems. This paper describes the work performed to validate the overall platform design, with a special emphasis on the solution to implement the HIPPS. An Audit of platform control and protection system has been performed to identify the most critical components, especially those used for the protection against overpressurization to verify any weak point design. All the analysis performed demonstrate that the adoption of HIPPS does not reduce in any way the overall platform safety level in terms of over-pressurisation risk.
