With the ZF 3000 NRD PTI, ZF is extending its maritime drive expertise to a new field of application. The new hybrid transmission, designed for power ranges up to 1,940 kW, offers a space- and weight-saving solution for implementing hybrid propulsion in waterjet vessels.
This enables low-noise and low-emission operation, ideal for use in ports and bays. Additionally, it provides powerful support in situations requiring rapid maneuvering. Sometimes, speed is essential, even on water. In these cases, manufacturers of yachts and workboats such as ferries, crew boats, and firefighting vessels often choose waterjet drives. According to ZF, the all-new ZF 3000 NRD PTI allows shipyards and designers to rely on a powerful and reliable solution for this type of propulsion.
New hybrid transmission bases on ZF 3000 series
The basis for the new hybrid waterjet transmission is the ZF 3000 series, which has already been successfully used in the market for several years. Customers can therefore count on a robust, durable, and powerful drive system. The ZF 3000 NRD PTI is designed for a maximum output of 1,940 kW and 7,560 Nm on the main drive, as well as 250 kW and 1,500 Nm on the electric power take-in (PTI). The closely coordinated ratio covers the range from i=1.093 to i=2.952. In addition, ZF is developing further variants – the ZF 5000 NRD PTI and ZF 8000 NRD PTI – to cover higher power ratings.
Thanks to its PTI capability, the ZF 3000 NRD PTI can be coupled with electric motors. This allows vessels equipped with this transmission to operate in protected waters, ports, or bays using a low-emission, low-noise drive. The quietness of the transmission in this configuration also enhances onboard comfort. Additionally, the electric motor can power onboard equipment.
With its compact design, the ZF 3000 NRD PTI fits into small engine rooms, providing designers with greater flexibility.
ZF has already received initial orders for the new ZF 3000 NRD PTI hybrid transmission and successfully implemented customer projects. Patrol boats and firefighting vessels outfitted with this system are currently operating reliably in Asia.
