Application Note High Integrity Pressure Protection System
(HIPPS) API 521, ASME Sec VIII Paragraph UG 140, Compliant HIPPS,
Shutdown Safety SystemDate: Aug 31, 2011
MICA Controls is proud to introduce to the Canadian market
place, a cost effective, ABSA approved High Integrity Pressure
Protection System (HIPPS) for use in protection against
overpressure scenarios without having to rely on relief valve
action and flare systems. Based on experience with Alberta
implemented HIPPS projects, our customers have told us what is
important to them: safe AND cost effective solutions. In our
experience the main reasons for using HIPPS are safety,
environmental, and economic. Safety to ensure that you can
confidently operate close to design limits. Environmental to avoid
unnecessary flaring and thereby limiting air emissions. And
economic to reduce costs, because it will be more cost affective to
use a HIPPS than to install full flaring capacity and full schedule
piping and equipment. The heart of the Safety Integrated System
(SIS) is the HIMA SIL3 rated PLC, consisting of logic solver and
I/O system, integrated with SIL rated sensors and Safety proven
final elements. Full protection with no overspending. Based on a
flexible hardware platform, HIMA safety PLCs can be adapted to meet
each companies integration requirement such as operating either as
standalone technology or integrated into the plant DCS or PLC
system.
MICAs turn-key system consists of HIPPS SIL verification report,
logic solver, pressure transmitters in 2oo3, and safety valves in
1oo2. All calculated for use in a SIL 3 application required by API
521 and ASME Sec VIII Paragraph UG 140. Our deliverables can
include the following: HAZOP of process package, including
P&IDs and functional description. Design for main and bypass
lines. Safety requirements specification, data sheets, instruments,
logic solver(s), final elements, and documentation Integration
including control narrative, logic diagrams, panel design, wiring
diagrams, HIMA HiMatrix system and HMI. Factory acceptance testing,
site acceptance testing, site integration function test,
commissioning, and start-up.

Above - Complete system installed for use on an emulsion inlet
line to a separator. Youll see a main inlet emulsion line and a
bypass inlet emulsion line used when the main valves are to be full
stroke tested. Right - All signals feed back into fault tolerant
HIMatrix F35 logic solvers.
