Hello,
I think I am the right person you are looking for. I am considered this proposal as ideally suited to my skills and experience.
I am HSE/process engineer with 8 years of experience in oil & gas industry. I have both field and office experience on a wide variety of projects. In my previous projects I was involved in every stage of project execution: from basic design, feasibility study, conceptual, through FEED, detail design and ends at commissioning and start-ups. I specialize in preparing PFDs and P&IDs, material and heat balances, hydraulic calculations, process simulations(Aspen Plus & Hysys), data sheets, technical specifications, operating procedures and many others.
My approach for any type of engineering documents/drawings is that I always provide full tractability of inputs, assumptions, equations and outputs to help reviewing, checking and usage by others.
My price is 20$/hour + freelancer.com fee. If you will send me the PFDs I will give you more details about the job. Then also we could negotiate the conditions.
If you have any questions please let me know.
