Frames, together with their partner Mokveld, completed two High Integrity Pressure Protection Systems (HIPPS) for the Pemex Lakach field Gas Collection Station. It is the first ever certified HIPPS in Mexico. The contract for the HIPPS was assigned to Frames by the Mexican construction company Arendal that has been awarded construction of the gas collection plant for the Lakach field.
To minimize on-site installation activities and to prevent installation errors on a system as critical as HIPPS, Frames designed a completely integrated skid mounted solution. This modular design reduces the number of interfaces and simplifies the certification of the HIPPS.
Each SIL3 certified HIPPS package consists of two Mokveld pneumatically actuated axial valves, pressure transmitters with interlocking manifold, and a programmable logic solver (PLC). Since the skids are located in a hazardous area, the logic solver is installed in an explosion proof cabinet complete with HMI.
To make sure that the HIPPS has high availability, a pneumatic buffer vessel is installed on each skid and the actuators are provided with passive fire protection. The HIPPS protects the Gas Collection Station against high pressure in case of a pressure control valve failure.
