B-193 Wellhead Platforms - HIPPS

­Application: HIPPS
Installation Area: Offshore Western India
Client: Oil & Natural Gas Corporation (ONGC)

Hima-Sella has supplied High Integrity Pressure P­rotection Systems (HIPPS) for use on five of Oil and Natural Gas Corporation’s (ONGC’s) unmanned well platforms; as part of the operator’s B-193 cluster development off Western India.

The HIPPS is a safety instrumented system designed to prevent over-pressurisation of downstream plant and equipment by isolating flows at source or at key points along a pipeline. Each HIPPS is independent of all other safety systems on the platforms - thus providing an isolated, fully autonomous and failsafe layer of protection – and comprises: three electronic pressure transducers; a dedicated HIQuad programmable electronic system (performing two-out-of-three voting on the transducers’ outputs) and HIPPS shutdown valve/actuator assemblies, each with dual solenoid valves (which are SIL 3 certified in accordance with BS EN 61508).

HIPPS panels are located in non-air-conditioned building modules on each platform and are powered from batteries which are kept topped up by solar panels. A particular challenge for this application was that the HIPPS had to draw very l­ittle power, and that was a driving factor in the selection of the HIMA HIQuad as the logic behind the system. Hima-Sella acted as the technical authority for the project, producing system documentation including calculations for the TUV to issue the SIL 3 certificates.
