Topsides Commissioning

In order to ensure a flawless initial startup, effective interface management between key engineering areas is critical and must be maintained throughout the life of the project from the preliminary FEED phase to sustainable steady-state production.

In GATE’s experience, major issues are often not detected until the initial startup of deepwater developments, causing deferred production and consequently many expensive changes. GATE gets involved early in the design process and applies a systems-wide engineering approach that negates many of the potential issues encountered during initial startups to minimize cost and schedule impacts.
