    3 System Descript ion

    High Integrity Pressure Protection System (HIPPS) is a specific application of a ShutdownSystem (ESD). The function of a HIPPS is to protect the downstream equipment (vessel or

    pipeline) against over-pressure by closing the source. Usually this is done by timely closing thededicated safety shut-off valve to prevent further pressurization of the piping downstream ofthis valve.

    The installation of the HIPPS at the Disouq Development Project shall reduce the pipelinedesign pressure to be 100 barg. This shall realise the following advantages:

      Reduced cost of pipeline - can constitute a significant portion of field development cost

      Reduced pressure rating of downstream equipment separators, process plant, etc.

      Increased safety by ensuring reduced pressure.

    The entire system, consist of final element, being a safety shut-off valve and its switchingunits, actuator, and mechanical pressure measuring devices able to initiate activation of safetyshut-off valve. These elements shall be all integrated into a single system.

    In accordance to lEC 61508, IEC 61511 and ISA TR84.00.02, the HIPPS, consisting of theelements defined above, shall be viewed as a Safety Integrity Function (SIF) and shall betreated as a dedicated safety loop. The loop shall meet the defined Safety Integrity Level. The

    assessed SIL level shall be calculated and confirmed by Vendor and audited by a certified 3rdparty. The following shall be considered when calculating the SIL level:

      Device integrity determined by documented and supportable failure rates

      Redundancy and voting using multiple devices to ensure fault tolerance

      Functional testing at specific intervals to determine that the device can achieve the fail

    safe condition

      Diagnostic coverage using automatic or on-line methods to detect component or device

    failure

      Other common causes including those related to the device, design, systematic faults,

    installation, and human error

    The HIPPS system shall be capable of standalone operation without reliance on externalpower supply or other DCS or ESD equipment.

    The HIPPS system shall be separated from the wellhead control system, and it shall act

    independently from the wellhead control system, and is configured so that it cannot be over-ridden by the normal control system.

    The HIPPS control system must be configured so that the shut off valve closes in the event ofa safety function failure: that is, the system is to “fail safe”.

    The HIPPS Vendor shall prove that the supplied system PFD meets the specified SIL level.

    The HIPPS design shall be based on hydraulic actuator with accumulator and hand pump forpressurisation.

    5 Design Requirements

    HIPPS vendor shall be responsible for the complete design, fabrication, testing, supply andguarantee of the HIPPS.

    Mechanical HIPPS shall have its own sensing, logic solver and final element loop and shall betotally self-contained.

    The mechanical system shall be standalone without requirement for external power sourceand therefore suitable for locations in remote areas.

    Considering the consequences relating to escape of gas, injury to personnel, economicallosses caused by damage to capital equipment, loss of production, the required SafetyIntegrity Level has been determined to be SIL 3 system certified according to IEC 61508 andIEC 61511complete with all required hardware configuration, accessories, hydraulic tubing toshut off valve, documentation & drawing requirements and test & inspection requirements.

    The required SIL level shall be met over the full lifecycle of the HIPPS. The design life of the

    HIPPS system shall be 25 years.HIPPS shall be certified according to IEC 61511 with respect to mechanical actuating andadditional requirements over & above IEC 61508 to achieve fast acting valve.

      The reaction speed of the safety shutoff valve.

      Determination of leakage rate of the safety shutoff valve.

    The interval for periodic testing may be one or two times per year, the vendor shall include inits offer the periodic testing as per above statement.

    The HIPPS design package shall be fully based on mechanical instrumentation in order to

    achieve the saving on power, installation cost and ease of use.

    The HIPPS shall be designed so that no consumption or external power sources of any kindsare required (fully self-contained).
