1 Objective, target group and provision

1.1 Objective The objective of this document is to describe technical requirements for control and choke valves. This specification shall govern the specification requirements regarding design, materials, fabrications, inspection and testing of all control and choke valves. For modifications on existing automation systems, some requirements in this TR may be in conflict with existing design. Conflicts shall be assessed prior to the modification, and where existing design shall be maintained, this shall be documented as local addendums to this TR.

1.2 Target group Main target group for this document is control and choke valve suppliers; however personnel and contractors involved in project development of new onshore and offshore facilities or modification of existing facilities should also be familiar with requirements in this document.

1.3 Provision This document is provided for in TR3030 (Automation, Technical Requirements and Standards).

2 General requirements Where reference is made to international and national standards and codes etc., the latest current issue shall apply. Valves shall be designed for the service and performance conditions specified on the instrument and process data sheets. Any conflicts between requirements specified herein and the requirements of any other referenced document shall be communicated to Company for clarification. Reference to Companys material data sheets (MDS) in TR2000 are used to apply additional material requirements for some components/materials. These MDSs can be found on the following internetsite: http://www.tr2000.no Relevant environmental data, such as relative humidity, maximum and minimum ambient temperature, shall be stated on the instrument data sheet. It is the Suppliers responsibility to request these data from the Purchaser, if not stated on the instrument data sheet. Supplier is responsible for supplying equipment suitable for the environmental data specified.



Page 5 of 40


3 Sizing and selection

3.1 Valve sizing Valve sizing calculations shall be carried out by Supplier based on IEC 60534-2, ISA 75.01, or by similar standards approved by Company. Process and piping data shall be specified by Purchaser on the process data sheet. The Supplier valve sizing programme shall be available to Company electronically. Sizing/flow calculations shall be provided for all process conditions specified. A control valve should be selected such that its capacity is between 120 to 140 % of the design capacity for a linear trim and between 130 to 160 % for an equal percentage trim.

3.2 Noise level Unless otherwise specified, maximum noise levels from control valves in continuous service shall not exceed 82 dBA at one meter distance from the valve, one meter downstream at normal process conditions. For valves in intermittent service, higher maximum noise levels may be approved by Company. The Supplier shall submit calculated noise levels for all process conditions specified. If the predicted noise level exceeds the given limit, Purchaser shall evaluate the valve with regard to location and process conditions prior to initiating implementation of noise control measures. Source treatment shall be the preferred method for noise reduction. Noise reduction by acoustic insulation shall be approved by Company prior to implementation.

3.3 Qualification of choke valves

3.3.1 General Qualification of choke valves may be required where choke collapse can cause overpressure. Analysis of the choke collapse scenario and the calculation of the associated relief loads are described in TR3001, section 4.6.4. Choke collapse shall be interpreted as one of the following:

1) Sudden increase in choke valve Cv caused by impact of objects 2) Sudden increase in choke valve Cv caused by fatigue (e.g. due to vibration or impact of small

objects) 3) Gradual increase in choke valve Cv caused by erosion

The requirements to qualification are different for 1), 2) and 3). Qualification testing will be required for 1) unless the relevant choke valve are previously qualified for similar conditions, while for 2) and 3) an evaluation to determine frequency of choke valve inspection intervals and methods will be required and can eliminate a requirement for testing. The decision whether or not the choke requires testing shall be made by the same instance that shall approve the Technology Qualification Plan (TQP), ref FR12. The qualification shall be carried out in accordance with Company's requirement for technology qualification as described in FR12. Requirement for qualification of choke shall be specified by Company if required. The qualification shall include an FMEA/FMECA. The FMEA/FMECA can result in:



Page 6 of 40


- Redesign of choke valve (e.g. as a result of fatigue analysis), or disqualification - Requirement for qualification testing - Requirement for monitoring of choke valve Cv during operation - Requirement for inspection of the choke valve during operation

Choke valves from certain Suppliers have been qualified on a case by case basis, and the validity of these qualifications is limited to certain designs/sizes, operating conditions and Cv. If it is demonstrated that the choke valve under consideration is covered by the tests already performed, in terms of designs/sizes, operating conditions and Cv, the choke valve can be considered qualified without additional testing.

3.3.2 Qualification testing The test program and acceptance criteria shall reflect the various failure modes and effects defined in the FMEA/FMECA. Typically, the conditions for impact testing shall cover both:

- the largest realistic object that may be expected in the well stream and that may hit the cage or its protection device (e.g. a brick stopper)

- smaller object/particles that may penetrate beyond any protection devices Typical objects may be solid material from the reservoir formation or from well perforation and clean-up, parts of completion/subsea tools, fragments from valves and debris from flowline pipe spools. The object velocity when entering the choke valve shall be considered to be equal to the fluid velocity. The fluid velocity shall be the maximum attainable during block valve maloperation, ref GL 3001 4.6.4.5. A lower object velocity may be determined by rigorous flow simulation of the upstream piping as a part of the technology qualification programme. When determining the impact velocity for the qualification the following shall be considered:

- flow path of the object inside the valve (i.e. the object may hit the valve body prior to impact) - angle of impact

Experience has shown that choke collapse may also be caused by fatigue, and test criteria for these mechanisms shall also be considered. The Supplier shall prepare a test procedure for the qualification testing. The test procedure shall be approved by Company and the test shall be witnessed and approved by Company.

4 Mechanical design criteria

4.1 General General requirements according to ASME B16.34 shall apply. The face to face dimensions should be in accordance with ISA S75 or ASME B16.10.
