TECHNICAL PRESENTATIONS (part 1):
Ring Corrosion Test to Evaluate H2S Corrosion Susceptibility of a Subsea
Pipeline in External Sour Environment, Tanvir Sumon, Saipem Ltd
1.2 Effect of Process Variables on Corrosion Behaviour of Duplex Grades, Janardhan Saithala, GL Noble Denton
2.1Tanvir Sumon (Saipem Ltd) asked a question on service experience of using PEX (cross-linked polyethylene) lined carbon steel for subsea water injection flowlines at 80/90 °C. Unfortunately, the attendees did not have any experience of using PEX for the application. He would welcome ideas from members not at the meeting.
2.2 Carol Powell (CDA) asked whether there was any knowledge of what sulphide levels constituted "polluted" in harbours, docksides and fitting out basins. The meeting thought that up to 1-2ppm could be found but the real problem was the sediment where SRBs lived; if this was disturbed, there might be transient levels of around say 25ppm.
2.3Robin Oakley (QinetiQ) raised the issue of corrosion under tiling in ship shower rooms, both in terms of possible Non-Destructive Inspection methods and also preventative measures. Several attendees suggested possible causes of the observed corrosion, and then possible modifications of the flooring system to prevent future occurrence were discussed.
The Committee were planning a small change to the
Constitution, which would be explained for the AGM, regarding Honorary
Committee also needs to be expanded to ensure that its meetings are quorate,
since pressure of work often keeps some of the members away.
The 4 meetings are held at 9.30am before each of the general meetings,
all remaining business being conducted by e-mail.
Anyone interested in volunteering should ask the Chairman or Secretariat
for further details.
