HIPPS

OUR EXPIERIENCE
Subsea & Offshore Systems designed, built and installed their first HIPPS package in 2003 and has quickly established itself as a market leader in the design, development, fabrication and commissioning of fully integrated HIPPS packages, having successfully installed over 47 systems through 2009.

For oil and gas producers, the loss of containment is a critical issue. Too much pressure on a vessel or pipeline can cause flammable, explosive, hazardous, or toxic chemicals to be released into the atmosphere – threatening lives and endangering the environment. The loss of containment can also severely impact a business’ bottom line when you consider the cost of replacing or repairing a production unit and potential production losses.

HIPPS are installed in place of conventional mechanical relief valves to handle large flow rates and high pressures, reducing the risk that a production unit exceeds its design pressure.

Because reliability is paramount, the International Electromechanical Commission (IEC) has introduced performance-based standards that HIPPS equipment must meet. Trusted Valve engineers its valves to meet or exceed the industry’s highest standards.

Operating Conditions:

Pressure Range: 1480 – 15,000 psi
Temperature: Ambient (-40C - 70C)
Sizes: 2 – 36 inches

THE BRAWN:
Subsea & Offshore Systems solution for the FINAL ELEMENT is a Trunnion mounted, double block and bleed ball valve. Our preference is to use metal seated technology, bubble tight to API 598, or at the very least, PEEK seated ball valves.

Our valves are supplied with a 4 year warranty on workmanship and materials and have been tested to insure their operation in
high speed applications. Subsea & Offshore Systems has supplied 30” ANSI 600 valves closing in 3 sec., 20” ANSI 1500 valves closing in <1sec., and 8” API 5000 ball closing in <1.5 sec.

The dual seat design provides positive bi-directional shut off, allowing for venting of the center body, solids proofing designs to prevent sand and trash from getting behind the seats, inline repairable options to reduce trim change down time and increase production, and metal to metal ball to seat technology to reduce seat and seal failure. Piggable, exotic metals.

A VALVE DESIGNED WITH THE CUSTOMER IN MIND

THE BRAINS:
The development of the HIPPS package is governed by IEC 61508 / 61511 which defines specific guidelines to configure the SIS to provide the necessary risk reduction and meet the required Safety Integrity Level (SIL)

The Logic Solver uses standard, proven, function block software and has available options which include partial stroke testing, valve function logging to support preventative maintenance operations and communications to all major DCS systems and customized third party communications interfaces.

The SIS controller can be provided up to a range of IEC 61508 SIL III platforms, to include scalable 2oo3 pressure transmitters and 1oo2 solenoid packages. The SIS choice is dictated by functionality and availability requirements, system cost and client preference.

All systems are independently certified third party, ensuring compliance to current legislation and industry standards.
