- High inspection capacity/short inspection period.
- Coated tank floors can be inspected.
- Automatic feature sizing and discrimination between internal and external features.
- Steerable in any direction, the TBIT can inspect the annular plates and areas close to the plate welds.
- High sensitivity to corrosion and low sensitivity to debris.
- Online data evaluation provides minute information about tank floor condition.
- Low profile tool design, enables remote controlled inspection of areas underneath heating coils and piping.
ROSEN’s TBIT uses a combination of Magnetic Flux Leakage (MFL) technology to detect and size corrosion defects and Eddy Current (EC) technology to determines the precise location of the defects – and, notably, whether they are on top or the bottom of the steel plates.
EC also provides information about the lift-off between the sensors and the steel plate. This makes it possible to distinguish corrosion from general debris and to inspect coated steel plates and surfaces in poor condition without the need for grit blasting.
TBIT is suitable for use in restricted areas, under pipes, heating coils, close to plate welds and annular plates. With a single TBIT up to 850 m2 of tank bottom can be inspected per day.
Data collected during the inspection process is integrated with a database containing detailed tank information and presented as both a hard-copy report and by means of our software, “ROSOFT for Tanks”. The Inspection data is assessed on-site with a report available immediately after the inspection is complete.
“ROSOFT for Tanks” is a versatile data management and viewing platform leading the operator through the entire maintenance process from inspection to assessment and repair planning. In addition, ROSOFT can be used to integrate inspection data from a range of inspection sources.
