ADVANCE NOTICE: 

1. 2013 is the 25th Anniversary of the Marine Corrosion Club/Forum

2. AGM in January - New Committee members required – please think if you might like to volunteer for this.  We meet for an hour before each meeting, but not everyone can get to all meetings, so we also do things by e-mail.  Main task: planning the Programme!

 

The Chairman (Robin Oakley) opened the meeting.  

1.   TECHNICAL PRESENTATIONS (part 1):  

1.1   'Risk Based Inspection Planning for Ageing Oil and Gas Assets', Steve Matthews, Plant Asset Management, Petrofac

1.2 ‘Engineering and Material Challenges for Dense Phase CO2 Pipeline Transport in High Pressure Dynamic Flow Mode’, Kumar Patchigolla, Cranfield University

 

2.   OPEN FORUM

2.1             Roger Francis (Rolled Alloys) asked whether anyone had seen an effect of heavy cold work of superduplex stainless steel on crevice corrosion in seawater.  Their previous work showed that cold work of 5 to 10% had no effect, but this was much more severe cold work.  There were no responses, so research is required.

2.2             Clive Tuck (Lloyd’s Register) asked if anyone knew who were the current experts in the marine biology of bio-fouling (macro-fouling).  Answers were mainly given by Keith Stokes (DSTL) and Graham Hill (ECHA Microbiology), who suggested the University of Southampton, The Institute of Oceanography in Southampton, Portsmouth University and (possibly) Plymouth University.

2.3             Robin Oakley (QinetiQ) asked for any suggestions of suppliers of test facilities for ultra-high pressure testing.  Steve Matthews (Petrofac) suggested trying Spadeadam ( where GL Nobel-Denton do fire and explosions tests etc for oil and gas industries).

2.4             Barry Torrance (Aish Technologies) described testing the electrical currents flowing in to and out of several sheets of freely corroding mild steel in 40-50 ohm-cm seawater.  Some of the currents changed polarity with time as the sheets vied to become anodic or cathodic to each other, but the total net current was, as expected, always zero.  What was surprising, however, was that the potentials relative to silver/silver chloride reference electrodes sited close to each sheet, settled down to around -740mV.  For freely corroding steel, around -600mV had been expected.  Could anyone think of an explanation for this? 

A number of possibilities were offered from the floor, including:

       (1)    Variation between manufacturers of Ag/AgCl electrodes.  Up to 80mV had been observed.

       (2)    Low dissolved oxygen.

       (3)    The presence of sulphides. An Azide test was recommended.

3.    TECHNICAL PRESENTATIONS  (part 2):  

3.1 'Valiant Jetty Project: HMNB Clyde: Faslane: Cathodic Protection’, Brian Wyatt, Corrosion Control Affiliates Ltd, John Thirkettle, Thor Corrosion & Chris Lynch, Corrpro Companies Europe Ltd

3.2    ‘Aluminium Alloys for the Marine Environment, Clive Tuck, Lloyd’s Register EMEA

The Chairman closed the meeting at approx. 3:15 pm
