Product Details Supplier Info More products

Hima-Sella has supplied high-integrity pressure protection systems (HIPPSs) for use on five of Oil and Natural Gas’s unmanned wellhead platforms as part of the operator’s B-193 cluster development off the coast of western India.

According to Hima-Sella, each HIPPS is independent of all other safety systems on the platforms, thus providing an isolated, fully autonomous and failsafe layer of protection.

Each system comprises three electronic pressure transducers, a dedicated Hiquad programmable electronic system and HIPPS shutdown valve/actuator assemblies, each with dual solenoid valves that 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 that are kept topped up by solar panels.

Key benefits of product application

  • The HIPPS safety instrumented systems help Oil and Natural Gas to prevent the over-pressurisation of downstream plant and equipment by isolating flows at the source or at key points along a pipeline.
  • The HIPPS units draw very little power, which is a key requirement for this application.
  • Hima-Sella acted as the technical authority for the project, producing system documentation including calculations for the TUV to issue the SIL 3 certificates.
