Abstract
Full Name : Nurul Asni Mohamed
Title / Position: Principal Engineer (Corrosion)
Company name : PETRONAS Group Technical Solutions
Ms Nurul Asni Mohamed is currently the Principal Engineer (Corrosion) with PETRONAS Group Technical Solutions. She started her career as a Maintenance Engineer with PETRONAS Dagangan Bhd (PDB) upon graduating in 1999 with a MEng in Materials Science and Engineering. Her career in the field of materials and corrosion started when she moved to PETRONAS Penapisan Melaka Sdn Bhd (PPMSB) in the year 2000 as the Materials/Corrosion Engineer. Nurul was a key member in the successful processing of high acid crudes, which PP(M)SB pioneered in Malaysia. She was also instrumental in setting up the Corrosion Management Program for the refinery, which was a first for PETRONAS downstream facilities in 2008. After 10 years at the refinery, Nurul was promoted to Principal Engineer at Group Technical Solutions (GTS) which sees the role elevated in the capacity of subject matter expert. After exposure to internal process corrosion, her current interest is with coatings as a means of corrosion protection. Nurul is actively involved with the Institute of Materials Malaysia as Chairman of the Fingerprinting Task Force, under the Polymers Committee and NACE where she was elected to NACE Founding Malaysia Section since 2015.
A costly recurring problem facing the Oil and Gas industry is premature failures of coatings for both offshore and onshore facilities. Although general industry experience has cited about 70% coating failures were attributed to surface preparation, application and inappropriate product use, addressing the paint production quality will have a significant impact to overall cost savings. A successful industry-academia collaboration rose to the challenge of answering the question of “Can we fingerprint coatings?” as no standard or document was currently available to provide specific acceptance guideline. Reference to fingerprint in ISO 20340 and NACE SP0108 were found to direct readers to manufacturer’s instructions in regards to FTIR analysis. The collaboration under the auspices of the Institute of Materials Malaysia, has successfully identified the acceptance criteria for specific FTIR regions for epoxy coating. An enhanced Coating Fingerprint Batch Certificate was developed and adopted into the PETRONAS Technical Standard (PTS) on Protective Coatings and Linings. Ongoing work by the collaboration includes analysis for other coating systems listed in PTS as well as overall implementation program.

Name: Pranavkumar Purani
Title / Position: International Market Development Manager (SEA)
Company: A W Chesterton Company
Since 2014 Mr. Purani has been the SE Asian Int’l Market Development Manager for the ARC brand of coatings. He is responsible to provide technical and market support for market/business development in South East Asia.
Mr. Purani holds a BS in Mechanical Engineering and has a Masters Degree in Business Administration. He has 24 years professional experience in sales, marketing, and product development in the field of high performance & specialty coatings.
There are a number of standards used in Oil and Gas Industries to qualify coatings. These standards can be API standards, EN standards and NACE standards that are specific to type of equipment and service conditions. Of the various test standards that oil companies employ to qualify organic liquid coatings, two standards are reviewed in this study. 1) NACE TM0185 - Evaluation of Internal Plastic Coatings for Corrosion Control of Tubular Goods by Autoclave Testing. 2) NACE TM0174 - Laboratory Methods for the Evaluation of Protective Coatings and Linings Materials on Metallic Substrates in Immersion Service. These two tests are included in the list of tests to qualify polymeric resin based coatings that are used in equipment such as separators, which are exposed to demanding conditions in terms of temperature, pressure, as well as exposure to sour gas and hydrocarbon gas and salt water. The test parameters for NACE TM 0185 are: temperature of exposure, pressure, duration of test, decompression rate, composition of gaseous environment as well as number of exposure cycles. The test parameters for TM 0174 are: temperature, liquid composition and time duration. In this paper, we review how major oil and gas corporations such as Aramco, Petrobras, Maersk and TOTAL utilize these two tests. We will show that there is a substantial difference in the test protocol and acceptance criteria employed by these companies.
Environmentally friendly protective coating system using water-borne fluropolymer top coat

Abstract
Name: Tsuyoshi Matsumoto
Title / Position: Deputy Manager
Company: Dai Nippon Toryo Co., Ltd.
I have responsible for the development of solvent borne and water borne protective coatings more than 10 years.
Majored in chemistry and materials enginnering in Shinsyu University, Japan. Joined Dai Nippon Toryo Co., Ltd, japan in 1998 as a chemist. Thirty-three years passed since fluoropolymer top coat was invented in 1983 in Japan. Many data were accumulated in the fields and laboratories. It has become older but surprisingly its performance is steel excellent after long year outdoor exposure tests. The fluoropolymer top coats are superior to other coatings such as polyurethane coatings especially in weathering performances. These characteristics of fluoropolymer come from its strong chemical bonding between carbon and fluorine atom in the molecular structure of FEVE (Fluoro-ethylene vinyl ether). They are highly resistant to ultraviolet rays. In this paper, the performances of newly developed waterborne fluoropolymer coatings and their protective paint systems were investigated on outdoor exposure tests and laboratory tests compared with previous solvent-borne fluoropolymer coatings. Protective coating systems used were composed of zinc rich primer of 80μm, epoxy paint of 120μm and fluoropolymer top coat of 55μm which are all waterborne paints. Reduction of VOC’s was achieved one sixth. These coating systems were applied to steel bridges, railway bridges, tanks so on. The protective systems are applicable to large scale structures such as offshore structures, offshore wind turbines, high raise towers. Water borne fluoropolymer top coat systems are recognized as low VOC and high durability which leads to double effect to environmentally friendly of VOC reduction in life time.
