Frames, supplier of oil & gas solutions and certified High Integrity Pressure Protection Systems (HIPPS) integrator, together with their partner Mokveld, completed two HIPPS for the Pemex Lakach field Gas Collection Station. It concerns one of the first ever certified HIPPS in Mexico. The contract for the HIPPS is assigned to Frames by the Mexican construction company Arendal that has been awarded to construct the gas collection plant for the Lakach field.
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. All the other equipment is also rated for use in a potentially explosive atmosphere.
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.
