    AMS offers a number of specialty training courses in the areas of process instrumentation, I&C maintenance, I&C aging management, online monitoring, equipment and process condition monitoring, and related subjects.

    Annual Courses
    AMS regularly holds a five-day course in the USA to cover the latest developments in I&C maintenance technologies. The same course is also conducted once every three years in Europe. The location of courses rotates annually to best fit the needs of attendees. AMS will also bring the course to the facility of any company or organization that enrolls at least five people.

    Custom Courses
    AMS can design courses to a client’s specification. Such courses are designed and developed in consultation with clients and are based on material compiled by AMS. The duration of the custom courses is usually two to three days; they are held at any location desired by the client, including AMS’ facilities.

    HMH with SMR model

    AMS president Dr. H.M. Hashemian showcases a new 3D model of a Small Modular Reactor (SMR), based on a design by NuScale Power. AMS is working on the design of new I&C sensors for SMRs and the adaptation of existing online monitoring technologies for I&C maintenance. The model shown here was produced using 3D printing technology to better visualize the unique geometries associated with SMRs.


    Dr. H.M. Hashemian, AMS President and CEO, and Mr. Ryan O’Hagan, Engineering Project Manager, recently gave a special technical course in Kharkov, Ukraine. Click here to read more and for photos of the event.
