The MV Semper Fi from the Nether- lands can be operated with two different engines at the same time: which effec- tively serves to cut emission of CO2 and save money. This innovative European inland waterway vessel measures 361 x 37.7 x 12.1 ft. (110 x 11.5 x 3.7 m).

In cooperation with MARIN, the Neth- erlands Maritime Research Institute in

Wageningen, the Dutch shipping compa- ny Carpe Diem Shipping developed the novel concept of Semper Fi , which re- portedly is the fi rst inland vessel that can simultaneously be propelled by a diesel engine and an electric motor – a unique combination, and one that has confi rmed a 10% savings in energy consumption.

The hybrid drive is not the only sen- sation of the SEMPER FI project. Con- tra-rotating rudder propellers of VETH

Propulsion type VZ-900A-CR-VHD, optimize the propulsion system. Propel- lers turning in opposite directions offer the decisive advantage in that they are not only made for improved maneuver- ability but also for extremely quiet op- eration – an important criteria for inland shipping. The streamlined tunnel and the variability of the propeller, which can be controlled in all directions, adds to the system’s effi ciency and versatility.

Thanks to an integrated exhaust post- treatment system with 4 SCRT which include catalytic converters and soot fi lters, the SEMPER FI makes an addi- tional contribution towards minimizing noxious emissions in inland shipping. In this process, the combustion gases are chemically cleaned using the so-called

AdBlue method. A urea-based liquid is injected to bind the exhaust particulates and reduce the levels of nitrogen oxides.

The AdBlue exhaust post-treatment sys- tem was supplied to the Semper Fi proj- ect by Veth Propulsion. The drive consist of: two Scania engines DI16 (512 kW / 1800 rpm), two E-engines (330 kW / 1800 rpm), two generating sets, Scania

DI16 (634 kVA / 1800 rpm), two fre- quency converters for propulsion,one frequency converter for bow thruster, one static converter to supply power to the board net, all supplied by VETH Pro- pulsion. 10% fuel savings
