The South Korean company STX Heavy Industries Co., Ltd. and Schottel will be cooperating in the area of large rudder propeller systems for underwater installation, as used on drilling rigs, for example. Within the framework of a corresponding licence agreement, STX will manufacture rudder propellers covering a power range from 2000 to 5800 kW, while Schottel will supply the core components for these systems in the form of the L gearbox. The first STX-Schottel Rudder propellers are due for delivery in the second half of 2010.
