Scope Overview

Large condensate storage tanks are difficult to inspect due to their confined geometry, limited access and the potential presence of hazardous atmospheres. Conventional inspection often requires scaffolding, man entry and extended shutdowns, increasing risk and reducing efficiency.

The aim was to complete full internal visual inspections of five large condensate tanks without man entry, providing clear condition insight to support the client’s integrity planning.

The Challenge

The client required a proven inspection method capable of:

• Capturing detailed internal imagery across all areas of each tank.

• Eliminating man entry and reducing confined space exposure.

• Delivering consistent, high quality data for engineering assessment.

• Minimising operational disruption and avoiding extended outages.

The Solution

Innovair deployed its ELIOS caged drone system, a purpose built platform for confined and hazardous environments. A two person team consisting of an inspection engineer and a qualified tank inspector carried out the full scope on site. The system enabled:

• General Visual Inspection and targeted Close Visual Inspection across 100% of internal surfaces.

• High resolution visual data with clear identification of defects and points of interest.

• Zero man entry, with all internal work completed remotely.

The Results

• More than two hundred flights completed, producing over thirty five hours of inspection data

• All points of interest identified during GVI were followed up with detailed CVI

• Comprehensive engineer verified inspection reports produced for each tank
