Detailed engineering services follow Front End Engineering Design verification to ensure that the key technical data in FEED documents is in-line with Project specifications, requirements and meeting the design criteria.
GRE capabilities include interdisciplinary coordination, communication at all levels and single point agenda i.e. to ensure successful and timely design completion that would allow site activities to be executed as planned.
