I'm a petroleum engineer specialized in down stream processes particularly in petroleum transportation and storage field, actually I did a seminar last year about this process which entitled by "Pipeline Pigging", I covered this topic from different aspects such us:- history, definition, functions, reasons of pigging, equipment of pigging system, types of pigs, pigging mediums, operation process, troubles shouting & maintenance, pig selection, pig motion analysis and cost of pigs operation. Moreover, we applied the pigging process on our graduation project as an additional work, and due to that our project ranked in the first place among other projects. So, indeed I have plenty of knowledge in this field and I'm sure that you will be surprised about the scientific basis, organization and professionalism of my output.
Just trust me, you will get more than what you will expect, I'm the right man in the right position.
