Systems Integration can be broadly defined as the collection of tasks and work areas that assure that the total system has been defined, conceived, and executed with appropriate attention to system requirements and constraints. Systems Integration personnel work closely with client personnel, functional leaders (Reservoir, D&C, Operations, Flow Assurance, Project Engineering, etc), with other contractors, and with the entire project team throughout the life of the project to coordinate, assist, and/or execute system-wide work activities.
