Sunil Pullarcot is a postgraduate in Mechanical Engineering having more than 38 years of industrial experience, one third of which is in oil & gas industry. During his career spanning over three and a half decades, he had worked in heavy fabrication and construction industry in a multitude of disciplines like, QA/QC, Engineering (Static & Rotating Equipment), Project Management, Construction Management and Commercial and that too in different roles representing manufacturer/contractor, consultant and finally as owner. Based on the vivid experience he gathered over years, he established himself as an accomplished trainer on topics related to Pressure Vessels, Heat Exchangers, Storage Tanks, Plant Piping, NDT and Welding. He is in the panel as Training Consultant to NExT, A Schlumberger Company, IBC Academy UK and an Approved ASME Instructor In his endeavor to pass on the valuable and unique experience he gained over 3 ½ decades to the forthcoming generations, Mr. Pullarcot has so far authored two books in his domain of expertise. They are Practical Guide to Pressure Vessel Manufacturing, published in 2002 and Above Ground Storage Tanks: Practical Guide to Construction, Inspection, and Testing published by CRC Press in 2015. Apart from the books, he published a few articles in renowned journals like Hydrocarbon Processing, Inspectioneering Journal and World Pipelines published from USA and UK in related topics. The book Process Plant Piping: Practical Guide to Fabrication, Installation, Inspection, Testing and Commissioning is his latest publication dealing with entire construction activities involved in Process Plant Piping, with all finer details, which often are not documented or considered relevant, especially in view of beginners in this field. Mr. Sunil Pullarcot is now retired from his last job as Specialist with Kuwait Oil Company and settled back in India.
