Owners Engineers

The OEM’s are pushing every plant to upgrade to their latest greatest technology. Not every plant needs to upgrade as urgently as is being stressed by the OEM’s. OEM’s make money selling upgraded systems. The OEM Sales Teams work on commission and will say or promise almost anything to get you to upgrade to their newest technology.

AP4 Services is dedicated to helping owners understand the who, what, when and why! We are committed to helping owners “spend smart money”. Our team is available to sit in on planning and negotiations with the OEM’s. When they see our team on your team, they know they cannot make promises they cannot keep. We keep the OEM honest and get a better value for your plant.

Sometimes an upgrade cannot be avoided and during the execution portion, our engineers watch over the OEM technicians to ensure they are following good practice and procedure. The demolition of the original systems can be the most critical step in the process. If the map isn’t made properly during Demo, the road can be easily lost causing schedule slip and making startup extremely difficult. We have seen weeks added on to outages because of poor execution plans.
