Pressure protection

Specialist safety systems integrator
Hima-Sella has supplied High
Integrity Pressure Protection Systems
(HIPPS) for use on five of Oil &
Natural Gas Corporation’s (ONGC’s)
unmanned wellhead platforms, as
part of the operator’s B-193 cluster
development off Western India.

Eddy Turnock, Hima-Sella’s sales
& marketing director, says: “Our
HIPPS is a safety instrumented
system designed to prevent overpressurisation
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 fail-safe layer of
protection – and comprises: three
electronic pressure transducers; a
dedicated HIQuad programmable
electronic system; and HIPPS
shutdown valve/actuator assemblies,
each with dual solenoid valves.
