Notes from Eurocorr on the relevant Working Parties & Standards Reports were presented, and are as follows: 

NACE MR0175 / ISO 15156
(Petroleum and natural gas industries – Materials for use in H2S-containing environments in oil & gas production)

– Conversion of HRc to Hv values for martensitic stainless steels.

– Cold worked austenitic stainless steels

– SCC test duration for nickel base alloys

– pH measurement (particularly at high Cl) 

NACE TG 328 (STG 32)
(Welding and fabrication of corrosion resistant alloys  – Corrosion issues in oil & gas production) 

ISO / CD 21457
(
Petroleum, petrochemical and natural gas industries – Materials selection for upstream operations)

        Raman Patel (HSE), Andrew Leonard (BP), Richard Carrol (BG)

ISO 23936
(
Petroleum, petrochemical and natural gas industries – Non-metallic materials in contact with media related to oil & gas production)

EFC WP 13 - Corrosion in Oil & Gas Production

  EFC16 Guidelines on material requirements for carbon and low alloy steels for H2S containing environments. - 3rd edition at publishers 

  EFC17   Corrosion resistant alloys for oil & gas production – Guidance on general requirements and test methods for H2S service. -Strain gauge formula incorrect. - Task group looking at 4 point bend procedures.

  EFC23   CO2 corrosion control in oil & gas production – Design         considerations. - Review of CO2 corrosion models undertaken.

  EFC39   Use of corrosion inhibition in oil & gas production. - Web based inhibitor selection. 

 

Eurocorr Sessions on

·       Main Marine Corrosion session: Ti+Super stainless HX tubing, NiAl Bronze, Super austenitics and Ni-based alloys.

·       Cathodic protection session covered modelling mooring chain CP and internal protection of pipes.

·       Separate “Copper-nickel alloy corrosion” session. 

EFC WP9: Marine Corrosion Working Party

·       Working party re-invigorated by new members (Chairman: Ulf Kivisakk of Sandvik, Anne-Marie Grolleau of DCNS and Carol Powell of CDA).

·       Proposal for new seawater test facility directory.

·       Offer format of current MCF seawater testing questionnaire as basis? 

·       Opportunities for to MCF support work of EFC?

·       Interest in obtaining EU support for Marine Corrosion research.

·       Proposal for introductory guide on Marine Corrosion for new engineers in the field

   The Avoidance of Corrosion in the Offshore Marine Environment -

   A Proposed EFC Document  

   1. Atmospheric Exposure - Coated Carbon Steel, Stainless Steel, Aluminium Alloys  

2. Immersed Exposure - Carbon Steel, Stainless Steel, Copper Alloys, Nickel Alloys, Titanium and its Alloys, Galvanic Corrosion
 
Thoughts: 

1) Are these sub-Sections sufficient to address the important issues?

2) Do we need a separate sub-section on welding or can these issues be addressed in the sub-sections?

3) Do we need a separate sub-section on galvanic corrosion?

4) It is envisaged that the carbon steel section under immersed exposure will mostly be addressing coatings and CP.  Is this the best way to tackle it?

5) Are there any classes of materials used offshore that have been omitted?

3.2   MCF News  Jean Tuck (Secretariat) mentioned that copies of the accounts could be obtained in advance of the Minutes, for those who wanted them.  CPD certificates were also available and could be claimed at the end of the meeting. 

A pdf Consultants List is in the final stages of preparation and will shortly be sent to members and placed on the MCF website.  Any member company wishing to take part should contact the Secretariat as soon as possible, so that they can be included in this edition.  The existing pdf Laboratories List will be updated before the end of the year.  The current version is on the website and will be circulated to participants for checking regarding any changes needed.  Again member companies are invited to be included if they have laboratories worldwide which are available to other companies.  Both these items are very useful when enquiries come into the MCF website, as information is then readily to hand. 

The next meeting would be the AGM.  Volunteers would be welcomed for the Management Committee.

3.3   Keith Stokes (DSTL) drew the US Department of Defense website, www.corrdefense.org, to the attention of the meeting.  This held much information likely to be of interest, including meetings and corrosion costs.  Games and educational videos were planned for future inclusion. 

Roger Francis mentioned that NACE were in the process of developing corrosion education packages for the US forces, covering such matters as coatings and problems.  

3.4    Roger Francis (RA Materials) informed the meetings that Weir Materials & Foundries had now been split.  The Foundries would now be known as Mathers Foundries, and the Materials section had been taken over by Rolled Alloys and would hence be known as RA Materials. 

3.5  Robin Oakley (QinetiQ) asked for ideas of corrosion test methods suitable to simulate Corrosion Under Insulation (CUI).  Phil Dent (Bodycote) directed enquirer to “ASTM G189: Laboratory simulation of corrosion under insulation”.  Roger Francis (RA Materials) suggested contacting Stefan Winnik from Exxon Mobil for advice, and supplied an email address. 

4.    TECHNICAL PRESENTATIONS  (part 2):

4.1  Advances in On-Line Corrosion Monitoring in Industrial Plants’, Mark Mulvaney, Rohrback Cosasco Systems UK Ltd.

4.2 ‘An Introduction to IMO – PSPC Coating Specification for Ballast Tanks’, John Carter, Bodycote Testing Ltd

The Chairman closed the meeting at approx. 3:30 pm
