NDT / NDE Background

Before traveling overseas, I worked for nine years as Level 2 at Errington Laboratories (a service inspection company later bought by Bodycote/Exova) carrying out UT, RT, MT, PT and VT in the UK and Europe for customers in all industrial sectors, including power generation (fossil fuel, nuclear and gas turbine), piping, pressure vessels, engineering, construction and aerospace. My last year was as divisional manager, before leaving to work in Brasil

I worked as Level 2 overseas for three years in Brasil (Petrobras approved Level D Ultrasonic Testing; jacket and module construction for off-shore), Brunei (Level II UT of off-shore structures where I was also responsible for writing, developing and implementing a procedure for underwater UT weld examination of TYK joints, including training of divers), and Bordeaux, France (UT, MT, RT, PT, VT of modules for off-shore).

On returning to the UK I started Applied Inspection Ltd with two colleagues. As CEO and senior NDT Level 3 I developed a multi-site operation initially with 3 staff rising to nearly 100. I designed and implementated complete business management systems at each of the company's branches including writing numerous UT, RT, MT, PT and VT procedures, techniques etc., for the company and its clients. We then sold the company to Acuren Inc./Rockwood Service Corp., USA.

I am currently working as a freelance NDT Level 3 from home. For a free quotation please go to the Contact page and send a message with details of your requirements.
