Frames completed HIPPS for Pemex Lakach deepwater gas field

July 20, 2016

Frames, certified HIPPS integrator, together with their partner Mokveld, completed two High Integrity Pressure Protection Systems (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.

Modular design for quick installation
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. 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.
 
Thomas de Wolf, Product Manager at Frames Flow Control & Safeguarding stated: “Together with our customer, Mokveld and other supply chain partners we were able to design and build the optimal solution for this project. Due to this cooperation, we were able to deliver the skids on time and to the full satisfaction of the customer and certifying authority (TÜV).”
 
IEC-61511 certified
As one of the only certified HIPPS integrators in the world, Frames is ideally suited to integrate a complex HIPPS package without any hassle for the customer. Arendal recognized the added value of Frames’ Functional Safety Management System that ensures the entire process of integration is performed in accordance with the IEC-61511 standard.
 
Protecting gas plant downstream
The HIPPS protects the Gas Collection Station against high pressure in case of a pressure control valve failure. A HIPPS plays a crucial role in site safety. By automatically bringing dangerous processes to a predictable safe state within a defined safety time, the HIPPS protects the site personnel, general public, and environment as well as valuable production assets.
