Oil & Gas Commissioning is a critical phase that ensures projects transition safely from construction to full operation. When performed with precision, it minimises risk, ensures compliance, and helps projects go live on time and within budget.

In the high-stakes oil and gas industry, failures during commissioning and mechanical completions can lead to costly downtime, environmental hazards, and lost profits. At Sixfold Group, we specialise in guiding startups and operators through this complex process with expertise, compliance, and efficiency.

Why Oil & Gas Commissioning Matters

Oil & Gas Commissioning validates that every system and component works according to design specifications before operations begin. It is the final checkpoint before the facility goes live, ensuring all equipment is tested, calibrated, and compliant with safety regulations.

What Is Mechanical Completion?

Mechanical completion involves verifying that all physical construction and installations are complete and meet quality standards. It includes documentation checks, punch list resolution, and handover to the commissioning team.

FAQs About Oil & Gas Commissioning

What is the goal of oil & gas commissioning?

The goal is to verify that all systems and components perform as designed before operations begin, ensuring safety, efficiency, and compliance.

---

How is mechanical completion different from commissioning?

Mechanical completion ensures all installations are built to spec and ready for commissioning. Commissioning is the testing phase that follows.

---

When should commissioning begin?

Commissioning planning should start early — ideally during the engineering phase — to align resources, timelines, and procedures.

---

Who is responsible for commissioning?

Typically, a commissioning manager or consultant (like Sixfold Group) leads the effort, working with engineering, construction, and operations teams.

---

What documents are needed for commissioning?

Key documents include commissioning plans, test procedures, handover certificates, safety validations, and compliance reports.
