Detailed Engineering

The development of the FEED to detailed engineering is achieved by a task force based team building. The multi-disciplinary engineering team is led by the Project Manager. The Project Manager ensures proper coordination and interface with all the discipline specialist engineers and the Client. The Project Manager is supported by Planning Engineers and Document Controllers. He ensures the Engineering deliverables meet the required Quality, Schedule and over all FEED development is achieved within the approved cost.
