Voith receives major order

4th Quarter 2012 Shaft power components

Voith has received a major order for the delivery of 60 variable-speed Vorecon planetary gears. They will enter service in oil fields 300 km off Rio de Janeiro. The operator is a consortium led by the Brazilian mineral oil group Petrobras.

Eight floating oil platforms will form the basis from which to extract oil from reserves contained in a huge pre-salt cluster up to seven kilometres below the water surface.

The operator is taking a new approach in exploiting the pre-salt cluster: a mixture of oil, gas and water is moved to the surface. The three constituents are then separated on special vessels. The crude oil is bunkered on ships, while the gas is returned to the subsea oil field and thus preserved for later utilisation. In the past, most of the gas was combusted and therefore lost.

The variable-speed planetary gear from Voith is a product that has proven itself for decades in reliable operation in the oil and gas industry and the Vorecon is an important part of the exploitation process. Compressors densify the gas for return transportation to the oil field. The compressors are driven by electric motors, whose speed is controlled by the Voith Vorecon. As a result, the gas has a constant pressure of up to 550 bar, independent of its highly varying density. Due to its compact, robust design and its high reliability, the Vorecon is ideal for the rough conditions in the Atlantic Ocean.
