B-193 Wellhead Platforms - HIPPS

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

SELLA CONTROLS 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. SELLA CONTROLS acted as the technical authority for the project, producing system documentation including calculations for TUV to issue the SIL 3 certificates.
