Early verification of the engineering contractors design is of vital importance in securing a successful initial start-up and operation of a plant.

SAT has developed a concept for Systems Verification in Engineering which cover the elements of operations in an integrated form. This allows for details of design to be checked and verified as soon as design documents are available. The technique is based on the Node Diagram (start-up diagram) developed by SAT during the Sleipner Field Development Projects.

The Node Diagram becomes the back bone of plant black start, initial start-up as well as trip-restart procedures. Equipment maintenance procedures and procedures for special operations are treated in a similar way. The result is the ability to operate the plant "on paper" at a very early stage in the design process, allowing for early detection of design errors or potential operating problems.

Development of operating manuals and System and Operation (SO) Books forms a naturally good background for creating operator training courses and CBT courses.
