The meeting was opened by the Immediate Past Chairman, Robin Oakley, who welcomed everyone to the meeting.

 1.      TECHNICAL PRESENTATIONS (part 1)

1.1  ‘Subsea Small Bore Tubing - Material Selection and Corrosion Risk Assessment’, Marco Rapone, GE Oil & Gas

1.2  ‘Biofouling and Corrosion in High Energy Tidal Environments’, Thomas Vance, Plymouth Marine Laboratory Applications

2.      OPEN FORUM.  

2.1     William Wistance (Lloyd's Register EMEA) presented a case which had been submitted to the Lloyd’s Register laboratory. This concerned a copper heat exchanger tube from a refrigeration plant. The tube (1.5mm wall thickness) had been found to have leaked and failure of the tube had been found to be as a result of ductile overload. However, optical and SEM micrographs had shown that cracks had developed in the tube prior to fracture and these were intergranular and branched, reminiscent of stress corrosion cracking. The tube was insulated by foam insulation and this was found to be wet with a poly-ester oil lubricant. Temperature range of operation had been given as between -10°C and +10°C.

Suggestions as to possible causes were discussed and these included ammonia, which may be present as a result of rodent activity or cleaning agents, impurities in the copper alloy and formicary corrosion due to deleterious agents in the insulating foam (which apparently had been seen on situations such as this in the past). An IR spectrum of the foam was suggested as a means of investigating the latter possibility.
 

2.2      Robin Oakley (Qinetic) gave notice that DEF STAN 02704 (Cathodic Protection of Naval Ships) is about to be updated. Apparently a draft was made of a possible update in 2006 but this was never published. Any comments from the membership on items which would be of relevance to the updating process would be welcomed.  

3   MCF NEWS   

Robin Jacob (CP Consultancy) gave an update on the actions of the MCF/ICorr Joint Committee on New Entries to Corrosion Engineering. He outlined the results of an Industry survey carried out by the Institute of Corrosion on recruitment requirement in the Corrosion Engineering sector. MCF member companies had contributed to supplying information for the survey. The main chart giving a summary of the results was presented and this indicated that there was an almost equal demand for recruits representing all ages and all qualification levels, therefore it is imperative that Corrosion Engineering is appropriately promoted in schools. Robin has been working with Haberdashers Schools in this respect and the Institute of Corrosion is preparing a presentation which it is planned would be used to promote the profession to schools by a group of volunteer presenters from industry. 75% of responders to the survey said that they supported the endeavour.

4.    TECHNICAL PRESENTATIONS  (part 2):

4.1 ‘Brighton Marina Breakwaters: Developing a Corrosion Management Strategy’, Jim Preston, Corrosion Prevention Ltd

4.2  ‘Influence of Localized Pit Distribution & Bench-Shaped Pits in the Ultimate Compressive Strength of Steel Plating for Shipping’ Yikun Wang, Julian Wharton & R Shenoi, University of Southampton

The Chairman closed the meeting at approx. 3:35 pm
