System Commissioning

An overview of commissioning, acceptance, and what to expect on site

WISE Group commissioning is a structured, multi-stage process that verifies your system is correctly installed, configured, and ready for operation — covering initial power-up checks, system testing, SAT, MRU verification, and operator training before handover.

What is the purpose of commissioning?

WISE Group commissioning ensures your system is installed correctly, configured as specified, and ready for safe, reliable operation.

Commissioning is a controlled, structured process that ensures reliable operation, maintains complete system documentation, and mitigates the risk of issues arising later in the system lifecycle.

Commissioning Is Not Always a Single Visit

Commissioning can happen in several stages, depending on your project.

The first round of commissioning typically takes place at a shipyard or integration site. A final visit is then required at the system’s operational location — this is common for installations such as FPSOs (Floating Production, Storage and Offloading vessels), where certain checks must be performed under live operating conditions.

Important Requirements Before Commissioning

System power-up

Do not power up the system before WISE Group engineers arrive on site, unless you have received written approval from WISE Group.

This way, our engineers can check everything before the system is powered up for the first time. These checks make sure wiring, connections, grounding, and safety features are all correct. If the system is powered too soon, problems might be missed and could cause delays or extra work later.

Sensor installation and handling

Please install and handle all sensors as described in the sensor documentation.

To maintain system integrity, sensors must be correctly positioned, sealed, and protected from the environment in accordance with the installation instructions. Non-compliance may result in moisture ingress or measurement inaccuracies — issues that may not be immediately apparent at initial power-up.

What Happens During Commissioning

Commissioning usually starts with a review of the system and how it was installed. WISE Group engineers then check the setup before configuring and testing the system in a controlled setting.

During testing, we watch how the system works, check alarms and data, and fix any problems we find. It’s normal to find some faults, especially the first time the system is powered up. This is part of the commissioning process.

Once the system is operating as specified, WISE Group engineers finalise the commissioning records and prepare the system for the formal acceptance stage.

Final Site Visit: Final Commissioning, SAT, Training and MRU Verification

For some installations, a final site visit is required at the operational location. This visit typically includes:

  • Final commissioning, where the system is verified under real operating conditions.

  • SAT (System Acceptance Test), which shows the system meets the agreed requirements at the final site.

  • MRU verification, where we check motion sensors while the vessel is moving. This is especially important for floating systems and for meeting requirements like CAP 437.

  • Training, where we show your team how to use the system, understand alarms, and handle basic troubleshooting.

This visit is a planned part of delivering your system and is not just a repeat of earlier commissioning steps.

Responsibility Boundaries

Shipyard or onboard staff often handle most of the mechanical and electrical installation.

WISE Group takes care of the final checks, commissioning, SAT, MRU verification, and training to make sure everything works correctly and is properly documented.

Warranty Considerations

The system warranty is conditional on correct installation and sensor handling, and on WISE Group carrying out commissioning and formal acceptance.

If the system is powered up prematurely, wired incorrectly, or sensors are not installed in accordance with the supplied documentation, the warranty may be invalidated for the affected components. Rectification work in such cases falls outside WISE Group's standard warranty scope and may incur additional costs.

After Commissioning and Acceptance

After commissioning and any final site work, your system transitions to normal operation. WISE Group completes all required handover documentation and provides ongoing support in accordance with your agreed support terms. To arrange support or report a post-commissioning issue, contact your WISE Group account representative or refer to your support agreement.

Key Takeaway

Commissioning and final acceptance are step-by-step processes that help ensure your system operates reliably in its intended environment and meets all documentation and regulatory requirements.

Following the agreed commissioning process and pre-requisite requirements is the most effective way to ensure a smooth handover, protect your warranty, and achieve long-term system reliability.
