AMPP TR21524-2023, Commentary on Standards Development for Selection and Qualification of HSC-Resistant Materials in Subsea Service with Cathodic Protection

Product Number: AMPP TR21524-2023
Publication Date: 2023
$109.00

As a companion document to MR21525, this Technical Report provides results, review and commentary on many investigations of HSC and includes important literature data, references, background information, service experience and related standards that were utilized in the development of the AMPP MR21525. Most of the information in this Technical Report covers findings from HSC field experience and HSC data from brine/CP exposure tests or from other cathodic charging experiments. It is important to note, in the use of MR21525 and in the review of data contained herein, that HSC can also be induced from hydrogenating environments and conditions other than from just from CP exposure alone. A non-exhaustive list of such conditions is presented later in this Technical Report.

Comments On Standards Development For Selection And Specification Of Subsea Materials

Product Number: 51322-17491-SG

Publication Date: 2022

In the oil and gas industry, the major standard for material selection today is ANSI1/NACE2 MR0175/ISO 15156 Parts 1-3. [1] While this standard deals extensively with environment cracking and its prevention for materials under exposure to production environments containing H2S, CO2, chlorides, and sulfur, it does not include any guidance or material requirements for resistance to environmental cracking (such as hydrogen stress cracking – HSC, or otherwise) under variable subsea conditions that involve exposure to seawater with varying levels of cathodic protection (CP). ISO 21457 [2] provides further guidance for materials selection and corrosion control for oil and gas production systems but does not provide adequate coverage of the issue of environmental cracking in subsea applications with CP.

Naturally Buffered Iron Chloride Containing Solutions for SSC Tests of Low Alloy Steels

Product Number: 51324-20732-SG
Author: Florian Thebault; Hervé Marchebois
Publication Date: 2024

Addition of controlled quantity of iron (II) chloride (FeCl2) in a test solution allows a tight control of the pH of Sulfide Stress Cracking (SSC) tests for low alloy steels. The natural buffering capacity is a consequence of the precipitation of iron sulfide corrosion products at a very early stage during the corrosion test. This work shows that FeCl2 can efficiently replace acetic acid for pH buffering of the SSC tests. NACE TM0177 Method A and D tests have been performed and showed similar environmental severity for SSC compared to standardized test solutions at a given pH. Thanks to a reduction of the corrosion rate in FeCl2 containing environments, which limits the increase of the applied stress during the test, the environmental severity appears to be fairly evaluated. Iron sulfide scale characterization and failure observations support the conclusion that FeCl2 containing solutions do not modify the SSC corrosion mechanism. This alternative test solution is well adapted to the determination of threshold pH for SSC.
