Dear all, I'm an inspection engineer in our petroleum refinery. I have almost 4 years experience in this field. I have the responsibility in ensuring the quality of repair and new works in tanks, process equipment (generally in shutdown period) like heat exchanger, column, furnace, pipelines pressure vessels, boiler etc. I think my field is very large. I want to be specialized in one or two fields. Pls help me in selecting the important fields that will create opportunity for work in future in foreign countries. Waiting for your kind reply.
