Presentation Overview:

There has been many iterations of test methods from coatings companies over the last 10-15 yrs looking at prequalification of CUI coatings. To a large extent this has not been standardised and accepted by the major Oil & Gas end users. Therefore over the last 3-4 years two CUI test method/prequalification standards have been worked on to solve this issue. This presentation will go through these tests methods and will hopefully

November Meeting

November Meeting

The November meeting was held at the Rosen Facility in Gosforth, and Barry Turner gave a presentation entitled, “A review of ISO 21809-3 standard for field joint coating”. Barry has over 30 years’ experience in industrial coatings and plastics for the oil and gas and water industry. He has a strong technical background with experience in sales, marketing, development and technical service positions, and is an active participant in ISO standardisation development for pipeline coatings as UK nominated expert.

ISO 21809-3 is becoming the recognised standard for the qualification and testing of field joint coatings on steel pipelines in the Oil and Gas sector. Barry presented his personal review of the 2016 revision of the standard and tried to put some light on the standard development process and explain the different material classes and associated issues and concerns. The presentation started with a historical look at the qualification of field joint coatings (FJC), viz:

DIN 30672-1 (2000) – Joint DIN/DVGW developed standard for tapes and shrinkable materials, with no cathodic protection, and max. temperature 50ºC.

EN 12068 (1999) – developed under CEN leadership for tapes and shrinkable materials, with cathodic protection, material defined maximum temperature, and offshore and “special situations” are excluded.

NF A49-716 (1998) – replaced by EN 10329 in 2006.  Covers 8 different coating types, as very diverse materials unable to standardise requirements.   End user to chose coating type.  (EN 10329 based on similar philosophy to 49-716).

The presentation then moved on to the dominant standard in North America, CSA Z245.30 (2014) developed by Canadian Standards, and which is a mandatory requirement in Canada for FJC,  but also for field applied coatings in general, covers 7 material classes. It also defines responsibilities of each party involved in a coating job and the qualification of materials, application procedures and individuals as applicators.  ISO 21809-11 is new and currently being drafted and will similarly be for field applied coatings but looking more toward external coating’s rehabilitation in the field. The bulk of the discussion held was on the ISO 21809 standard and especially the different coatings classes, ie., Part 1, Polyolefin coatings (3-layer PE and 3-layer PP) and currently under revision; Part 2, Single layer fusion bonded epoxy coatings; Part 3, Field joint coatings; Part 4, Polyethylene coatings (2 layer PE) ; Part 5, External concrete coatings ; Part 6, Dual layer and Multi layer fusion bonded epoxy coatings (NEW, currrently in development);
and Part 11, Coatings for in-field application, coating repairs and rehabilitation.

Everyone that attended found the talk very informative and resulting in a lot of discussion.

The Branch had their summer event at Hatfield College Durham on 6 July, including a very interesting tour of Durham Castle with a wee bit of a history lesson!

Durham castle is the ancient palace of the Prince Bishops of Durham. It was built on the order of William the Conqueror on his return from Scotland in 1072 as a projection of the Norman kings power in the North of England. Strangely enough he thought we were a bit ‘wild’, no change there then! The tour took us around the two chapels, the Norman chapel built in 1078 & Tunstall’s chapel built in 1540 exclusively for the Prince Bishop. The last wish of the Prince Bishop in 1837 was to leave the castle and all surrounding land to form the University, which at the time was heavily challenged by London and the government, but they thankfully lost. To this date it it is still owned as used by Durham University and quite frankly is impressive. It is a fully functional home to students who use the grand ballroom for breakfast and dinner, and the upper floors are now student accommodation for the lucky ones.

The second part of the evening was taken up by a very informative and interesting look at “UK Energy Past, Present and Future” presented by Prof Jon Gluyas, who is currently Dean of Knowledge Exchange and Director of Energy Institute Durham University. The presentation covered the issues of the ENERGY TRILEMA which within the UK is seen as relating to Equity/Sustainability/Security.  The origins of the petroleum age were described with three important landmark discoveries, Bibi – Aybat Caspian 1846, Spindletop – Texas 1901, and Masjed e Suleyman – Iran 1908.  The use of Mineral Oil really took off in the 1860’s and led to reduction in use of Whale Oil therefore resulting in the reduction of whale Hunting!  One of the most frightening statistics was that there have been no large Oil discoveries for over 50 years which has resulted in a decline in global reserves.  The audience was  taken through the issues of declining oil and gas prices and the resultant increase in consumption which again is putting major stresses on reserves. The increase in USA on Shale Gas is having little effect on the reserves which were steady from the 80’s but the gap is narrowing.

The presentation then turned to the situation in the UK showing the trend in energy production and consumption and again a widening energy gap was described through which we as a nation need to address from within the UK. Recent headlines show what is happening to our energy base, the last three deep coal mines are to close resulting in increased imports of coal for the remaining coal fired power stations, Ferrybridge power station to close, and oil & gas platform decommissioning accelerating in some cases 10 years early.

In the 1980’s the UK was self-sufficient in coal/gas/oil, but today is increasing our import of these. Most of our gas consumption is imported from Norway and Qatar, which is a real issue at the moment and we are talking about increasing imports. Most of Europe’s gas in controlled by Russia! Currently UK has 14 days of gas reserves whereas France & Germany have 100 days.

Finally the UK is cancelling many green energy policies making renewables more expensive as currently gas and oil are low in price. UK is considering following US lead and drawing upon fracking as an energy source as well as increasing reliance on nuclear. In summary these are interesting times in the energy industry and the UK needs to find ways of improving its self-sufficiency. One potential source is Geothermal which is estimated to be around 100 years worth of low carbon heating here in the UK, with potential centres in Cheshire, East Yorkshire and Wessex, to name a few. Utilisation of this technology could cut UK emissions by up to 38%.

The second branch meeting of the year was held on 27 April at the Rosen UK facility in Gosforth.  The well attended meeting included David David Mobbs (chairman London branch) and the President of Institute of Corrosion, Sarah Vasey. 

Malcolm Morris, Technical Support Manager Sherwin Williams, presented an in depth technical review of ISO standards and detailed the process that is undertaken in various levels of standards’ committees – local, national and international. ISO committees can be split down into, Technical committees – TC’s, Sub committees – SC’s and Working Groups – WG’s.  However there are also other groups which can influence the development of standards namely, IPPIC – International Paint & Printing Ink committee and CEPE – European Confederation of Paint and Ink Manufacturers.   In particular, Malcolm updated the audience on the current changes to the ISO 12944-6 standard with regard to updating the performance requirements for the various environments.

Many members of the audience were unaware that there were so many steps to go through to get modifications made to standards, and the description of the current process was very informative. There were numerous questions from the audience relating to the correlation of anticorrosive testing in the laboratory with actual field data. There were definite concerns that there was indeed no correlation and therefore how could the data be relied upon. It became very evident that the key to understanding the performance of coating was still looking at ‘track record’ of coatings in a particular environment. The comments from the meeting really showed what an emotive topic this is, and how much it matters to get these standards right.
