Product News | Versatrax 450 TTC™

The inuksuk, a symbol representing something acting or performing in place of humans, wasn’t chosen as Inuktun’s logo by coincidence. This concept is more apparent than ever in Inuktun’s new advanced crawler vehicle, the Versatrax 450 Tank and Tunnel Crawler™ (VT450™). The innovative VT450™ adopts Inuktun’s proven technology and boasts of many unique enhancements

While in its compact state, the VT450™ might be deceiving at first glance. The four-function manipulator that unfolds from the crawler, the precision gripper that can be guided by the integrated cameras, the main Spectrum 90™ video camera that raises to a full upright position, and even the extended 6000 series Minitracs™ that provide four (4) inches of vehicle clearance might escape your initial attention. However, it is precisely these features that make the VT450TM system one of the industry’s most versatile inspection and handling robots for confined space applications.

Although it was originally designed specifically for operation inside of tunnels, the VT450TM is seeing other uses in tank inspection, clean-up, and decontamination.. It is perfectly suited for a wide range of other industrial applications where remote viewing and handling are required. This vehicle reflects the meaning of the inuksuk and the passion that motivates Inuktun.

Brian Storie, Director of Inuktun Europe, recently met with Willie Watt, General Manager at Subsea 7, to discuss supporting a very unique and time sensitive pipeline inspection project for Subsea 7’s client, BP.

Technically speaking, the inspection application was a newly constructed 14 inch pipeline with a welded stainless steel liner; the welds were of critical interest. The inspection segment was around 30 metres / 98 feet long and included two challenging 5D bends at 30 degrees, ascending and descending. This pipeline system, fabricated onshore in the North of Scotland at Subsea 7’s Wester Site in Wick, will be launched and transported in one piece using Controlled Depth Tow Method. The pipelines at 7,500 metres / 24,606 feet long are the longest manmade object ever transported and once installed offshore in the BP Andrew field in the central North Sea, the pipeline will carry oil from the Kinoull well back to the Andrew oil platform.

Brian and Willie met to review pipeline drawings, discuss equipment options and test-drive the Versatrax 150™ (VT150) crawler. The rugged steerable vehicle with its inspection route capacity was well received, as was the Spectrum 90™ PTZ color video camera on-board; its adjustable exposure control supported clear views of the highly-reflective stainless steel.

With a solution in place, Subsea 7 called upon Inuktun's Rental Department for delivery of a Versatrax 150™. Brian Storie said: "The project came together quickly after the VT150™ demonstration. Subsea 7 called me on Tuesday and they completed the inspection on Friday".

Inuktun Europe delivered the crawler system and consulted on its operation. The Versatrax 150™ surpassed expectations completing four uninterrupted pipeline runs in less than five hours. As anticipated, the Spectrum 90™ camera captured Subsea 7 logoimpressive video footage of the stainless steel liner.

Tech Tips | Choosing the Right Track Material

Inuktun has a strong and long established reputation for small, rugged, and waterproof crawler modules; the Minitrac™ and Microtrac™. Although the benefits of our standard brass crawler tracks are familiar to many, the advantages of our aluminum and stainless steel versions are often overlooked. This Tech Tip illustrates some of the benefits of the different materials.

Aluminum
Inuktun's aluminum crawler tracks are normally recommended during system design when portability, vertical operation, or large payloads are important. As you might expect, they dramatically reduce total vehicle weight. Aluminum weighs about 50% less than brass and stainless steel allowing for the addition of larger payloads or magnetic attachments. Standard aluminum tracks are anodized to reduce corrosion and prolong operable life, but they are not recommended for some caustic conditions (sodium hydroxide, for example, can result in hydrogen off-gassing in the presence of aluminum).

Brass
Pulling tether on long range mobile inspection systems requires substantial traction; Inuktun's brass tracks offer the weight needed in these situations. In addition, brass tracks have other advantages that should be considered:

  1. They are more resistant to certain harsh solutions (e.g. chlorinated solvents),
  2. They are more economical than stainless steel,
  3. They are less likely to cause sparks when impacting other materials.

Stainless Steel
Stainless steel tracks are roughly the same weight as brass and offer equal pull. Stainless steel offers the broadest chemical compatibility and is generally preferred for use in radioactive environments as it is easy to decontaminate.
