API TR 17TR6 pdf download Attributes of Production Chemicals in Subsea Production Systems
This document identifies and specifies the essential attributes of production chemicals intended to be introduced tosubsea oil and gas production systems.
The document is intended for use by chemical suppliers to faciliate the provision of chemicals compatible withexisting and intended subsea production systems (SPS) although it is envisaged that use of the document forspecification purposes by the operators of such processes, will assist in ensuring the completeness of requests tosupply.
The application of the document requires acceptance of the principle that it is the supplier’s responsibility to ensurethat the chemicals supplied are fit for purpose and safe to use, although it is acknowledged that this responsibility canonly be fulfilled if specification of requirements is complete. To this end the document identfies essential informationthat only SPs designers and operators can provide but without knowledge of which, suppliers should not supply. Inthe requirements of this document, responsibility for obtaining these items of critical information is placed upon thesupplier, in the expectation that designers and operators will respond with their ready provision.
The functional performance of production chemicals is outside the scope of this document.
The assessments and tests specified in this document are not intended to qualify materials for use in an SPs inrespect of pressure containment, mechanical load, cyclic mechanical load, or other design parameters.
The chemical-chemical compatibility of production chemicals at their respective application concentrations is alsooutside the scope of this document as is the effect of any incompatibility on their respective functional performance.
Finally,this document does not consider the health, safety, or environmental (HS&E) implications of deploying aproduction chemical in an sPs.
NOTE Attention is drawn to the fact that the tests specfied in this document can generate data and information about the effectof a chemicalmaterial incompatibility on the integrity of a material used in a SPS, that could necessitate aditional testing, outsidethe scope of this document. Such aditional testing should however be undertaken in order to ensure that all possible mechanismsthat could threaten the integrity of a production, transportation, or chemical injection system are fully evaluated.
The following referenced documents are indispensable for the application of this document. For dated references,only the edition cited applies. For undated references, the latest edition of the referenced document (including anyamendments) applies.

3.1 Terms and Definitions
For the purposes of this document, the following definitions apply.3.1.1
Feature of a subsea production system that is fixed and inherent to the existence of the SPs.NOTE Examples of SPS attributes are a material of construction or the volume of a vessel.
Biological or chemical agent that prevents bacterial reproduction without kiling or otherwise harming the bacteria.
Element forming part of a pressure-containing envelope which is designed to prevent unintentional flow of producedlinjected fluids, particularly to the external environment.
