Commissioning and turnaround: when every hour matters

Whether starting up a new facility or restarting a plant after a scheduled shutdown, tightness testing is a critical — and time-pressured — phase. Every pipe, flange, and valve must be verified before going online. A single missed leak can delay restart, holding up production and leaving entire teams waiting for additional tightness testing to be completed.

Traditional methods each have limits: soap spray does not scale to thousands of components; sniffers are slow on extensive piping networks; OGI cameras cannot detect air or nitrogen, which are the gases most commonly used to pressurize systems during tightness testing.

Distran acoustic cameras detect any gas under pressure, at any scale, from a safe distance. Shell, TotalEnergies, BASF, and Air Liquide rely on Distran to complete tightness testing faster, with fewer people, and with full coverage confidence.

Save shifts

A single operator covers more ground in a fraction of the time compared to soap spray or sniffers

Detect All Gas Types

Detect leaks in air, nitrogen, and any gas with one device.

Find leaks where you don’t expect them

With a 180° detection angle, leaks are detected across dense piping, elevated equipment, and hard-to-access areas.

Usable by any operator

Ready to use after a short introduction, with no specialized training required.

Reduce Manpower

One operator replaces the teams required for point-by-point soap spray inspections.

Operate Safely

Inspect from a safe distance with no contact with the gas. ATEX/IECEx certified.

TotalEnergies Feyzin: Turnaround with Zero Tolerance for Leaks

TotalEnergies' Feyzin refinery runs scheduled shutdowns involving up to 100 people over 5 weeks. Before any unit can restart, every component must be verified, including the ~1,300 flanges in the Alkylation unit alone. Any delay in returning to production is costly, and a restart with an undetected leak is not an option.

The team replaced soap spray with the Distran Ultra Pro X. Operators now locate leaks from 30–40 m away without scaffolding, inspect complex units from the ground, and consistently meet the site's "zero leaks" requirement before every restart. The camera is now available 24/7 in control rooms across the platform.

"The Ultra Pro X has become an indispensable tool — it is constantly in use in the various units."

Shell Vito: Full coverage, faster commissioning

During the commissioning of Shell’s Vito platform, teams deployed Distran cameras to verify tightness across the entire installation before startup.

The Ultra Pro located every leak quickly and precisely, allowing teams to cover the full scope of the installation and complete inspections faster — with confidence that the system was fully leak-tight before going live.

During commissioning, we pressurize the system with air. The Distran camera finds and locates leaks quickly. It is extremely sensitive. With it, we can pick up the smallest of sounds. It saves our teams a lot of time while making sure the system is safe and leak-tight.
