Reinforced Concrete Steel Cylinder Pipe (RCCP)
Bingöl - 2 HEPP is a diversion type hydropower facility which makes use of the head between 1 180 m and 1 095 m of Göynük Stream. The construction of the project commenced in 2012 and the HEPP is going to be in commercial activity in 2014.
Bingöl – 2 is located in a very high seismicity area of Turkey with a peak ground acceleration estimated around 0.5 g, close to the vicinity of faults. In the original design, 12 km long trapezoidal channel located in slopes was planned. Prosem Engineering investigated the site area and consulted specialists; consequently the former design was replaced with a buried and pressurized reinforced concrete steel cylinder pipe (RCCP) with the diameter of 4.1 m near the river in order to eliminate the risk of slope stability failures which might have been triggered by an earthquake event. The RCCP was chosen to Steel, HDPE and GRP alternatives because of its lower cost and in situ fabrication eliminating hauling expenses. The weir was moved downstream in order to increase the active storage which increased peak energy production; also this resulted in a shorter length of conveyance around 8 km.
