Oliver Twinsafe Supplies Critical Components for HIPPS Application

Oliver Twinsafe has secured an order for 30 API 6A 1 13/16″ valves and 30 flushing rings, supporting a High Integrity Pressure Protection System (HIPPS) for an FPSO application.

When pressure rises beyond safe operating limits, a HIPPS is designed to act quickly, isolating the process before the excess pressure can reach downstream equipment. It provides an additional layer of protection within a process facility, helping to safeguard equipment and maintain safe operating conditions.

The latest order forms part of this critical protection function. The 30 valves will work alongside pressure transmitters, with flushing rings providing the necessary connection points for the instrumentation.

The equipment will serve 10 lines, each incorporating three pressure transmitters, giving a total of 30 pressure transmitter positions. This enables pressure to be monitored at multiple points, providing the system with the information required to identify potentially unsafe conditions.

Valve selection is particularly important within a HIPPS, where isolation needs to be dependable when the system is called upon to respond. The API 6A specification of the valves makes them suited to applications where robust pressure-containing equipment is required.

The order also demonstrates the importance of considering the wider system when specifying valve technology. Rather than supplying valves as standalone components, Oliver Twinsafe has provided the associated flushing rings required to integrate the pressure transmitters into the system.

As pressure protection continues to be a key consideration across complex process facilities, HIPPS provide an important safeguard against overpressure events. Oliver Twinsafe’s involvement in this application reflects its experience in supplying specialist valve technology for systems where reliability, pressure control and safe isolation are essential.
