VARIO and CB climbing units - completely cost-effective



The South Pars Gas Field in the Persian Gulf has the world’s largest natural gas deposits. The gas reserves lying under the seabed are divided between Iran and the Emirate of Qatar. For a number of years now, development of the production capacities in southern Iran has been accelerated, aimed at having a gas production rate of 820 million m³ per day. Among other things, numerous liquid gas tanks have been built in order to provide temporary storage facilities for the huge quantities.

PERI´s Iranian engineers supported the construction site team with the building of the altogether 16 circular containers - butane tanks with 45 m and propane tanks with 50 m internal diameters respectively. With the VARIO GT 24 girder wall formwork system and the CB climbing scaffold, an economical climbing formwork solution was developed. For each structure, 40 and 44 moving units were used internally and externally respectively - with a length of 3.80 m in each case - in order to construct the 60 cm thick and almost 40 m high reinforced concrete walls with concreting cycle heights of 3 m. Timber formers mounted on the VARIO panels provided the exact curvature for the formlining while VARIO articulated couplings friction-locked the steel walers in position. At the same time, the PERI formwork planning took into consideration pilasters which had been integrated in the circular structures with 1.30 m wall thicknesses.

The large-sized formwork panels were connected to the CB climbing platforms by means of strongbacks and formwork carriages. For moving a complete climbing unit including the finishing platforms, one crane pick was sufficient - shuttering and striking were carried out with the roller-mounted carriage without a crane.

    “For a project like this, the right choice of formwork system is tremendously important. We decided in favour of PERI because the systems are easy to use and ensure safe operational sequences. In connection with the PERI implementation planning and the construction site support, we can achieve fast cycle times.”
