Saudi Aramco: Company General Use

The following parts and paragraph numbers refer to API STD 617, Eighth Edition,

which is a part of this specification. The text in each paragraph below is an addition,

unless noted as an exception, modification, or deletion to API STD 617. Paragraph

numbers not appearing in API STD 617 are new paragraphs to be inserted in numerical

order. The requirements of this specification have precedence over the content of

API STD 617.

Part 1 – General Requirements

1 Scope

1.1 Scope

(Modification) This specification, together with the Data Sheet (SA-2812)

and the Purchase Order, covers mandatory requirements for centrifugal,

axial, and integrally geared compressors and expander-compressors.

1.1.2 Experience Requirements

Compressor Systems shall be supplied by Vendors qualified by experience

in manufacturing the units proposed. To qualify, the Vendor must have

manufactured at the proposed location of manufacture at least two

compressors/expanders of comparable design and configuration, speed,

power rating, and discharge pressure for a gas of comparable

characteristics to that of the intended duty. These compressors/expanders

must have been in continuous operation for two years or more without

problems. If the proposed location of manufacture is other than the

Vendor's originally approved facility (for example a licensee facility or an

acquired/merged facility) the Vendor must demonstrate compliance with

these qualification requirements for that facility.

The Vendor must demonstrate his experience on an individual component

and service condition basis, as listed below. Experience need not be

concentrated in a single reference, but may be spread through several

operating referenced designs. To qualify, the component installed in these

machines must have been in continuous operation in equivalent or more

severe duty for two years or more without problems.

The critical areas relative to equivalent service conditions which must be

demonstrated to the satisfaction of Saudi Aramco include, but are not

limited to the following:

1) Pressure

2) Gas composition, contaminants, Mol.Weight, and highest density

3) Volumetric capacity and volume ratio

4) Power rating

5) Speed and Distance between bearings

6) Temperature

The critical areas relative to component design which must be

demonstrated to the satisfaction of Saudi Aramco include the following:

1) Dry Gas Seals and sealing system, which must be of a comparable

design and configuration, diameter, peripheral speed, power rating,

and differential pressure for a gas of comparable characteristics to

that of the intended duty

2) Bearing design and loading

3) Number of stages and staging arrangement

4) Casing size, design, and pressure rating

5) Casing joint design

6) Impellers and expander wheel structural design, power, and

performance

7) Material selection

In the area of component design, the Vendor must show that each

component has operated under similar or more severe conditions than

those of the proposed machine.

1.3 Conflicting Requirements

(Exception) Any conflicts between this document and other applicable

Mandatory Saudi Aramco Engineering Requirements (MSAERs) shall be

addressed to the EK&RD Coordinator.

Any deviation from the requirements herein shall follow internal company

procedure SAEP-302.

2 Normative References

Material or equipment supplied to this specification shall also comply with applicable

sections of the latest edition (unless an edition is specified) of the references listed

below or in the body of this document.
