Ron Selva, Engineering Director, TCR Arabia – PP Simtech
Mr. Ron Selva has over 35 years of experience in design, construction, Damage Mechanisms inspection and integrity management of static equipment items of a plant. His credentials include:

Mr. Selva is the Engineering Director of PP SIMTECH Solutions Ltd, a TCR Arabia partner company, based in the UK and a founder member of the company in 1997. The company specializes in providing asset integrity managing technology services globally.

Under Mr. Selva’s leadership PP SIMTECH is renowned for the development of a robust and innovative RBI technology process during the late nineties. This technology process is considered as “unparalleled in its application”, in articles published by companies such as British Petroleum and GPIC (Bahrain), compared to any other RBI methods available in the market. This best practice technology process is also supported by a fully transparent and auditable rbiAsystTM software system, which was jointly developed with British Petroleum in 2001 and is fully owned by PP SIMTECH. In recent years, he has successfully developed a robust and practical methodology for linking Fitness-For-Service (FFS) assessment results into the RBI assessment process.

He has over 14 years experience in RBI implementation and facilitating RBI team studies, covering a variety of plants in oil, gas, petrochemical, fertilizer manufacturing & sea water desalination industries.

Mr. Selva has over 35 years of industry recognised experience in design, construction, Damage Mechanisms inspection, and risk based integrity management of static equipment items of a plant.

During the 1980’s, he was responsible for the development of an innovative FFS assessment methodology and safety case arguments using fracture mechanics technology, which was used in the evaluation and verification of the long term integrity of nuclear reactor pressure vessels and other critical equipments in the primary pressure circuit. The safety case based on this principle was successfully presented to the UK Nuclear Installation Inspectorate and the Nuclear Safety Advisory Committee to the UK Parliament. Due to its success, the application of this methodology and the logic was later extended to cover other critical and high consequence equipment items in the refining, petrochemical and fertilizer industry. These procedures have been later incorporated into the UK and European Standards and Guidance related to Fitness-For-Service (FFS) and inspection interval assessments of equipment containing thinning damage or crack-like defects.

Mr. Selva successfully developed methods and carried out several high profile FFS and inspection assessments to resolve complex problems widespread across the industry relating to a variety of critical equipment items experiencing different types of damage. For example, NH3 storage tanks affected by SCC; large storage spheres in refineries affected by H2 damage; superheater headers subjected to creep/fatigue damage and reheat cracking; pressure swing absorbers affected by fatigue cracking; deaerators and industrial boilers subjected to corrosion fatigue; heavy wall reactors made of Hastelloy material affected by Inter Granular Corrosion and SCC.

In 2002, along with a team of senior metallurgists from PP SIMTECH and two multi-national refining and petrochemical client companies, he championed the development of susceptibility assessment models for nearly 70 Damage Mechanisms relating to oil & gas, petrochemical, fertilizer, power generation and sea water desalination industries for effective use in RBI implementation team studies and FFS assessments.

Mr. Selva is an active member of several British Standards Institute (BSI) Technical Committees responsible for the development of codes and standards: Since 1989 – involved in the development of FFS assessment codes PD 6493 and BS 7910, many of these procedures are now included in the FFS guidance API 579; from 1991 – involved in the development of the Pressure Vessel Design and Construction code BS 5500; since 1999 – involved in the development of the High Temperature Creep Assessment guidance. Additionally, he is credited for his substantial contribution to the development of the European Guidelines for NH3 storage tanks inspection intervals assessment, using RBI and FFS technologies.

He has several years experience of delivering training in static equipment Design, FFS, RBI and DMs to inspection & design engineers and RBI study team members from various engineering disciplines.

Due to global recognition of his knowledge in asset integrity managing technologies, Mr. Selva has presented several papers on RBI Best Practice and Fitness-For-Service by invitation from high profile clients and organisers of various technical conferences worldwide.
