Terberg "coil truck" for the oil industry

Monday, January 14th 2008

In cooperation with ASEP based in Groot Ammers, Terberg has developed a special 8x8 truck for the oil industry. This vehicle can be used to clean drilled oil wells down to depths of over 10 km. A drive unit is mounted above a drilled oil well, from which a steel line with an injection head is sunk into the well. The interior of the shaft is cleaned at a pressure of over 300 bar to ensure that production stays on track. The Volvo PTO engine is used to drive the assembly. This vehicle has a large reel between the 2nd and 3rd axle, which can be adjusted upwards or downwards. The steel tubing is coiled onto the reel. The demand for larger reel diameters combined with all-wheel-drive trucks is growing because of the need to drill down to increasingly deeper depths for oil sources in remote areas. Various diameters of steel tubing can be coiled onto the reel, ranging from 1.25" to 2.38". It is possible to opt for a maximum vehicle height of 4 m, onto which 12.28 km of 1.25" tubing can be coiled. In areas where there are no restrictions on vehicle heights, it is possible to have a reel giving a vehicle height of 4.6 m. At least 17.3 km(!) of 1.25” tubing can be coiled onto such a reel.

The assembly is driven by the Volvo D13A 440 hp Euro 5 engine and a ZF 16S2225TO manual shift transmission. The familiar Axle Tech axles are used in combination with a ZF-Steyr VG2700 transfer box. To equip the vehicle with a large reel, the drive of the transfer box is mounted at a very low height by axle 3. The Terberg Coiltruck comes with a drive that is mounted on the height-adjustable reel. This means that the clearance below the reel on the site can be increased by approximately 400 mm.

The front axles are equipped with stabi-air suspension combined with Dynalastic rubber suspension on the rear axles. The vehicle is also equipped with an Arctic pack so that it can operate in areas with temperatures ranging from -40°C to + 50°C. The vehicle will mainly be used in Russia and the Middle East.
