The "trac-scan" series is a new delivery technology exclusively designed and built by iicorr, two systems are in service at the moment with a third system in the final stages of design. By the end of 2005 it is hoped there will be 4 systems in the operational pool.

The first system was designed and built for a specific project where normal scanning tools and pigging technology could not fulfil the operators requirements. The first trac-scan system was deployed in 2004 and was a complete success, resulting in over a £700,000 cost saving for the operator.

The trac-scan system is in essence a multi-purpose delivery package, as standard it is fitted with lighting, camera and scanning arm, the design of the unit arm allows the single axis motor to perform twin axis C-Scan wall mapping by the unique design of the "helix-scanner unit"

The twin trac system is fitted with a high-tension spring roller, this allows for the navigation of tighter bends in the line; the spring roller also provides the track's with constant traction on the pipe surface

The unit can be fitted with ultrasonic or eddy-current probes, the standard system has a reach of 300mt with conventional umbilical but can be fitted with up to 2.5km of fibre-optic control umbilical. The units current configuration is set for 14" lines, this can be varied +/- 2" and by varying the chassis larger applications can be inspected

During the 2004 project the unit was fitted with ¾" high pressure jetting hose to clear the internal surface of the pipe-line.

The trac-scan system can scan internally on all planes, horizontally or vertically including bends. The IC01 is currently undergoing design work with a view of attaching recovery and manipulator arms, this type of technology could be used to recover pigs, remove debris, insert plugs etc

The IC02 in-line trac-scan system is the latest operational system designed and built by iicorr, this system was built for a specific project where previously redundant risers and flowline were required to be inspected to verify their use for hydrocarbon transportation.

The IC02 system as standard is fitted with a camera and scanning unit, the scanning module can also be changed for a high pressure-water 4-jet module.

In its current configuration the unit is set to 6" but this can be varied.

The IC03 currently under the final stages of design review, this will be a three trac system capable of ultrasonic (compression and shear wave) eddy current inspection on pipelines and tubulars of 24" and upwards.

The fourth system in development will be of a similar design but for much larger applications with a longer reach using fibre-optic control.
