IntroductionThe overall objective of the project is to upgrade the existing Field Instrumentation of the TAWKE CPF wellhead and the provision of full SCADA system. Project Scope The intent of this specification is to define the minimum requirements and give recommendation for the instrument upgrade of the whole TAWKE CPF wellheads. The works shall involve all that is necessary and incidental to the successful change out of all instruments and commissioning of the SCADA system as part of the work scope.General RequirementThis specification is general and all instruments/systems included may not be required for the package in question. Only the portion related to the instruments/systems included in the scope of supply of Contractor for a particular package.The detailed scope of work, specific job requirements, exclusions, deviations, additions etc. if any, will be indicated in the material requisition, equipment or plant specifications and addendum to this specification.This specification provides only the qualitative specifications of commonly used instruments. Instruments not covered in this specification shall be submitted by the bidder for approval.Contractor shall be fully responsible for design, material selection, sizing and selection of the proper instruments for their system. The compliance to this specification does not absolve the vendor of the responsibility towards contractual obligations with regards to completeness, proper selection, satisfactory operation and easy maintenance of the unit.All equipment supplied shall be of field proven quality both with respect to design and materials. Prototype instruments or instruments of an experimental nature shall not be offered or supplied.Pressure MeasurementPressure transmitters shall be built on an application proven sensor technology capable of providing accurate and stable pressure measurement with internal temperature and static pressure compensation. In addition to compliance with the following detailed specifications, transmitters shall be of industrial quality offering integration, maintenance and operational savings based on advanced features such as:

Pressure Transmitter (Gauge / Differential)Static Pressure Compensation & Display/OutputDifferential pressure transmitters shall be internally corrected for static pressure shifts with the static pressure value available for transmission via HART protocol and available on the device local display. Modular DesignTransmitters shall be of a modular design supporting the replacement of electronics modules (communications/protocol cards, terminal boards, & displays) in the field without the need to remove power in all electrical environments (general purpose, increased safety and intrinsically safe) except flame proof where agency codes do not permit the housings to be opened. To enable maintenance and operational savings, transmitter modularity must support simple field replacements without device removal or process shutdown.Advanced DisplayDisplays capable of multiple views, custom engineering units, trending and bar graph views and supportive of advanced applications such as transmitter messaging and maintenance mode indications shall be optionally available and easily added in the field after installation without process interruption.Intuitive MMI ConfigurationThe combination of display technology and external interface buttons must support the ability to easily configure devices in the field without the use of a handheld field communicator. In addition configuration shall also be accomplished via: Handheld field device capable of communicating both HART and DE protocols. Device management software able to utilize either DTM or DD/EDDL configuration files.Polarity InsensitivityTo avoid unnecessary field rework on start-up, transmitters shall not only be protected from, but also insensitive to reverse polarity connections. Reverse wiring shall not affect the performance of the transmitters eliminating post installation re-work. Total PerformanceTransmitters shall be capable of total performance specifications of up to .12% of span when running at elevated process conditions with transmitter turndown at 5:1, temperature deviations up to 50oC and static pressures (differential pressure units) of up to 1000 psig.Transmitter Meter Body and Electronics Meter Body & Sensing ElementSensor Technology:The transmitter sensor technology shall be piezo-resistive sensor technology capable of providing embedded temperature and static pressure (differential pressure models) compensation to correct for errors due to process temperature and static pressure variations.Sensor Materials (Wetted & Non-Wetted): Sensor fill fluid shall be standard Silicone DC 200 oil.All non-wetted materials shall be a minimum of 316SS. Wetted materials such as the process diaphragm(s) shall be a minimum of 316L SS with optional materials available for the diaphragm and process heads (flanges) as follows: Optional Wetted Materials - DiaphragmsHastelloy C 276Gold Plated 316L SSMonel 400 Gold Plated Hastelloy C-276TantalumGold Plated Monel 400 Optional Materials - Head (Flange)Zinc Plated Carbon SteelHastelloy C -276316 SS Monel 400Optional Materials Gaskets/O-rings:Teflon/Glass filled PTFE StandardViton - OptionalGraphite OptionalVent/Drain: Where applicable vent/drains shall be available on the end or the face of the process heads with material to match the process heads except carbon steel will be 316SS. The vent/drain may be selected as either standard or center vents (for directing process venting and or draining via separately applied tubing).
