In-Situ Methods For Corrosion Evaluation

16 August, Tuesday - Sabah Room - 1:35pm - 2:05pm

Bio of Speaker


Full Name :  Siew Leong Wai
Title / Position:   Lead Inspection Engineer
Company name :  ExxonMobil Chemical Operations Pte. Ltd.

Siew Leong Wai is a Lead Inspection Engineer at Jurong Refinery, ExxonMobil Asia Pacific Pte. Ltd. He graduated from Nanyang Technological University in Bachelor Degree (Honours) in Mechanical and Production Enngineering. He has ten years of industrial experiences in heat treatment industry sector before joining Exxonmobil in 2008. 
His present role is leading an inspection team in Risk Based Inspection programs as well as Statutory inspection to meet safety, environmental and reliability requirements.  He is involved in areas of materials, corrosion and inspection of fixed equipment and process piping in Chemical and Refinery units, providing engineering assessment, engineering design, corrosion control, plant trouble shooting and equipment failure root cause analysis (RCFA). He has attained certifications in AWS CWI (2009), API 570 (2009), API510 (2010); NACE CP 1 (2012).
Corrosion management and the impact of it have been viewed as direct effect on both capital and operational expenditures (CAPEX and OPEX) and health, safety and the environment (HSE). Aging facilities, increasing stringent HSE requirements and environmental cost, together with the needed flexibility to process higher corrosivity crude for better profit margins have posed great challenges to the refining industry.  Appropriate application of corrosion monitoring systems are paramount particularly when processing lower cost crudes or “opportunity crudes” with higher TAN (Total Acid Number) can results in higher naphthenic acid and sulfidation corrosion in processing units.
This paper will provide a brief review on the traditional  corrosion evaluation techniques with the applications focus in the oil and gas industry. This paper aims to cover the application and learnings of the pervasive wireless corrosion evaluation system successfully installed in the targeted units to achieve greater reliability for critical asset management.

Practical Assets Integrity Management – Challenges and Solution

16 August, Tuesday - Sabah Room - 2:10pm - 2:40pm

Bio of Speaker


Name:  Andrew Mills
Title / Position:  Director – Integrity Management
Company:  Wood Group Kenny

A materials engineer by training, Andrew has over 20 years of experience in the fields of integrity, risk, maintenance and materials technology.  Andrew has spent time developing, reviewing, auditing, and implementing Integrity Management systems in many countries.  He has acted as an independent consultant to the West Australian Government Regulator on issues of plant and pipeline integrity.   He has been with Wood Group, for 15 years, including 2 years in KL and 7 years in Jakarta, and is currently based in Perth, with global involvement in Wood Group’s integrity management offerings.
​Andrew’s session will primarily be focused on some of the strategies and tools for managing integrity in plant & facilities. The talk will cover high-level aspect of integrity management, some of the keys to achieving success, as well as some practical case studies, tips, and tricks gained from developing, implementing and assessing integrity management programs. At the higher level, aspect of developing integrity management system and assessing the performance of challenges of these system will be discussed, with an overview of some of the strategies in PA555/ISO55000. In addition. The practical challenges of implementation of asset integrity management stems will be raised, together with some approaches to solve these challenges. Andrew will discuss in particular the use of advanced RBI, such as quantitative financial RBI systems, and outline the advantages and disadvantages of adopting this type of RBI approach. As part of this, monitoring strategies, new inspection and monitoring tools, and the use of integrity operating windows will be discussed. The practical management of CUI, A perennial problems, will be discussed, together with management of Pressure Safety Systems (E.g PRVs). Data analysis, especially of inspection date and the use of statistic to provide a better window into the condition of equipment will be demonstrated. 

Knowledge is Critical: What Data is Need to Control your Internal Corrosion?

16 August, Tuesday - Sabah Room - 2:45pm - 3:15pm

Bio of Speaker


Name: Rolf Gubner
Title / Position:  Professor of Corrosion/Deputy Director 
Company:  Curtin University

Rolf Gubner joined Curtin University in 2008 as Chevron-Woodside Chair in Corrosion Engineering. His main task was to develop the corrosion group into a corrosion centre with focus in oil and gas. This was achieved in 2013 and today his focus has shifted towards technology and knowledge transfer between different industries to combat corrosion cost effective.
Prior to his move to Australia, he was department head for Industrial Processes at the Swedish Corrosion Institute working on automotive, pulp&paper, drinking water and microbiologically influenced corrosion solutions for industry.
What data is needed to understand the internal state of your assets? What will allow you to operate your pipeline safely, cost effectively and extend the life of your assets? We will discuss the monitoring and inspection data needed to assess the true state of your assets and how you use this data to make effective short and long term decisions on your asset integrity. Economic, safety and public image concerns will be addressed as we attempt to clarify the many monitoring and inspection methods available, which are the most cost effective and technically sound, and when you may need to think outside the box to solve your internal corrosion evaluations.​
