In reaction to the increasing commuter traffic on the Bosporus, the municipal ferry enterprise IDO in Istanbul has commissioned four doubleended ferries with two Voith Schneider Propellers each. The four ferries operate on the route between the European ferry terminal Sirkeci and the Asian terminal Harem. With the increased number of ferries on this route, the transport capacity was boosted from 2,500 vehicles to approx. 10,000 vehicles per day. The four double-ended ferries are equipped with a total of eight Voith Schneider Propellers of the type 18R5 EC/150-1.
