Commissioning Services

The aim of the GATE Commissioning team is to ensure the equipment is commissioned in a safe and controlled manner while confirming compliance with the design intent and demonstrating system and equipment performance.

Lessons learned from our past projects have shown that more commissioning oversight is required during both the engineering and the construction phases to ensure that quality and operability are maintained throughout the project life cycle. That is why we propose early involvement in the project to facilitate a systematic, efficient and flawless transfer from contractor to operations.

We recognize that every project has many interdependencies between each function. By getting involved early in the project, we can manage these links and fully understand, adjust and adapt to Project and Operations strategies and priorities throughout the life cycle of the project and into steady state operations. GATE is committed to providing high quality services to support the activities of our Clients.


Offshore Oil & Gas Commissioning

Due to the complexity and multitude of disciplines that encompass oil and gas developments, effective planning is imperative in order to achieve first production in the safest and fastest way possible.

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 commissioning and initial startup, which minimizes cost and schedule impacts.

GATE Completion System (GCS)

The GATE Completion System (GCS) is a project management and certification tool specifically designed for the efficient execution of all Systems Completion phases (Mechanical Completion, Static and Dynamic Commissioning), as well as being capable of providing complete support through the lifecycle of the project from FEED to decommissioning.

The main objective of GCS is to achieve Systems Completion for a specific Project and be able to demonstrate each phase with controlled and traceable sets of information structured according to the project’s Systems and Subsystems, allowing proper handover / turnover to the client.
