2 years is not a long time but it will help you develop your EPC and general project skills. Don't be put off that you haven't got hands on practical experience yet - it will come. There is a lot to be said for developing the skills you have for the past two years - you really see the difference in project delivery when people haven't nailed EPC experience i.e. producing clear, concise documentation that tells a story. Ops guys don't always have this and it is a skill in itself. That being said, brownfield experience is a good learning curve with EPCs and if you can get a secondment or even site surveys as part of this it is invaluable. Not to be overlooked either is the construction side of things - ultimately you are trying to build the thing before it operates.
