1. TECHNICAL PRESENTATIONS

Click for abstracts

1.1 'Development of Very High Strength Copper Alloys with Resistance to Hydrogen Embrittlement and Stress Corrosion Cracking’, Clive Tuck (Langley Alloys)

1.2 'Oil and Gas Corrosion Related Work of LR EMEA’, Graham Gibb (LR EMEA Aberdeen)

2. OPEN FORUM

2.1. Anode safety

Barry Torrance was gathering information (papers, regulations, experience etc) on the safety of divers/swimmers working in the vicinity of ICCP anodes. This had also been raised
at the Jan ‘05 MCF meeting. There had been a good number of responses from members, and his recent thread on the NACE Corrosion Network had also generated some useful results.

2.2. Deepwater Materials Considerations

Clive Tuck asked if the initial conjectures about deepwater effects had been found in practice, now that installations had been operating in these environments for some years. Had fears that CP systems would not operate effectively due to lack of calcareous scale, and that potentials would be forced more negative, been found to be correct? Apparently a joint industry study on this (of which Total are a member) is involved in investigating this but has not released any findings publicly. A US Navy study on corrosion through differential aeration due to differences in water depth has been published which verifies that this phenomenon certainly needs to be addressed by materials engineers.

2.3 NACE website

Stuart Bond, having just been involved with the NACE Task Group concerned with materials for service, notified those present that the MR-01-77/BS EN 15156 revision document was now available for review and comments on the NACE website. He understood that this was available for non-members of NACE as well as for members.

3. TECHNICAL PRESENTATIONS (part 2)

3.1 ‘Cathodic Protection of reinforced concrete in the marine environment’, Jim Preston (Corrosion Control Services Ltd)

3.2 Keynote lecture: 'Cathodic Protection of Offshore Systems Based on the New ISO Standard 15889-2. Some Practical Applications’, Svein Eliassen (Statoil)

The Chairman closed the meeting at approx. 5:25 pm
