Cost Optimisation Approach to External Corrosion Maintenance Management- A Technical Perspective

18 August, Thursday - Sabah Room - 1:35pm - 2:05pm

Bio of Speaker


Full Name :  Rehan Ahmed
Title / Position :  
Company name :  PETRONAS Carigali

Rehan’s area of focus has been to develop and explore new and emerging technologies in the field of Coating, Corrosion, Insulation RBI approach and proposing solutions to the challenges which come along with maintaining a very large Onshore(Coastal) and Offshore Facility, ensuring optimal performance and plant reliability, which in turn will translate into Gas, Condensate and other derivative deliverability.

His profile also includes development of Cathodic Protection monitoring system to all underground structures and pipelines, in addition to rehabilitation of Sea Water intake and outfall structures.

He has also worked on developing long term corrosion control measures including thermally sprayed metals, and developing his expertise in the field of chemical inhibition in open and closed loop cooling water systems, and boiler feed water chemistry

He is currently heading the Materials Corrosion and Inspection (MCI)  team in Operations Excellence Department in Petronas Carigali and is engaged in improving on current MCI practices being followed in that organisation
Cost optimisation approach to external corrosion maintenance management- A technical perspective
With the fall in oil & Gas prices, there is a rush by producers and contractors to optimize cost of maintenance corrosion management. In most cases it results in cost deferment, and often results in false economy as the issues return to bits during better periods. This paper intends to explore the alternative approach to external corrosion management on utilization of technology and best practices/back to basics approach to sustain a minimum level of corrosion protection to maintain asset integrity.

Implementation and Success of Corrosion Management Program (CMP) in PETRONAS

18 August, Thursday - Sabah Room - 2:10pm - 2:40pm

Bio of Speaker


Name:  M Zaid Kamardin
Title / Position:  Staff Engineer (Corrosion)

M Zaid Kamardin graduated in Mechanical Engineering from University of Sydney, Australia. He joined PETRONAS Refinery Terengganu in Feb 2006. He started his career as QAQC Engineer for Special Project Department before joining Inspection Unit as Corrosion Engineer. In Mar 2013, he was promoted to Staff Engineer (Corrosion). He joined PETRONAS Group Technical Solution (GTS) in Oct 2015.
M Zaid is certified as NACE Senior Corrosion Technologist and also several other NACE and API certifications.
As PETRONAS grows, the challenge to meet operational requirement without compromising integrity of aging facilities has necessitated for improvement to existing integrity management and chemical treatment program. PETRONAS’s Corrosion Management Program (CMP) is developed to enhance and complement existing risk-based inspection program. By leveraging operational experience and knowledge of subject matter expert (SME) from various discipline including Operation, Process, Maintenance, Inspection and Corrosion, leading indicator for integrity, also known as Integrity Operating Window (IOW), is identified and defined. IOW includes process parameters that has impact on equipment degradation. In addition, to information from corrosion control including chemical treatment (corrosion inhibitor, biocide etc.) is monitored and correlated with corrosion monitoring data to ensure its effectiveness . Specific response to deviation is also defined in CMP to allow for rapid mitigation and limit the exposure to detrimental condition. CMP implementation at PETRONAS plants and facilities has contributed to reduction of risk, elimination of premature failure, extension of facilities life and optimization of inspection and maintenance cost.

The New wave of composite repair systems- Inspection and validation​

18 August, Thursday - Sabah Room - 2:45pm - 3:15pm

Bio of Speaker


Name: Liew Shann Chiang
Title / Position:  Business Development Manager (Asia Pacific)
Company:  NRI

Shann Ching LIEW is the Business Development Manager – Asia Pacific for Neptune Research Inc. (NRI).  He is a graduate in Materials Engineering from Tunku Abdul Rahman University College, Kuala Lumpur, Malaysia.
Shann Ching works as production engineer in steel pipe manufacturing plant who is specializing in welding and pipe coating prior to joining HEMPEL as Assistant Technical Service Manager in 2003. During his employment with HEMPEL, he has been trained internally and externally in coating technology, surface preparation, application, failure analysis, inspection and coating specification. Prior to joining NRI, he was holding the position of Deputy General Manager at Hempel.
He is a certified Painting Inspector Level III according to Norwegian Standard NS 476 by The Norwegian Professional Council for Education and Certification of Inspectors for Surface Treatment (FROSIO). He is also a certificated Protective Coating Specialist by National Association of Corrosion Engineers (NACE).
He has been involved in coatings for more than 15 years, conducting inspections, specification, failure analysis and training for various segments from pipe coating, marine, industrial and offshore.
The growth of composite repair systems in recent years as utilized by the refinery and chemical plant industry for the repair and rehabilitation of piping systems has also grown the need for advancements in the technology. One critical aspect of these repair systems is how to inspect and validate them for fitness for service. Until recently, the inspection and validation methods have been based on visual and subjective techniques. A recent advancement in composite repair technology now allows for full radiographic inspection of the composite repair system for proper validation and quality assurance. This new technology represents the biggest advancement in composite repair systems for piping in the last decade and allows a full fitness for service program to be implemented for these repairs which has been limited in the past.
This paper will discuss the testing completed for fiberglass and carbon fiber composite repair systems with specialty epoxy for full inspection capabilities. The test results for compliance with industry standards will be shown as well as detailed inspection techniques and results.
