The ‘Ernst Kramer’ inland waterway vessel is 104.97 metres long, 9.50 metres wide, has a maximum draught of 3.15 metres and is designed to carry cargo weighing 2,273,645 tonnes. Those responsible for the project converted some of the analogue processes on board in order to be able to control the main engine, the rudder, the bow thruster, the radio and radar equipment using radio waves from a distance. Following some initial test operations in July this year, Rhenus has now presented the unusual project at the 13th National Maritime Conference, the leading event organised by the German government to strengthen the maritime economy.
The public were able to gain some idea of the many opportunities opened up by remote-controlled inland waterway shipping on the FernBin stand in the conference centre: skippers, Bernhard Buche und Herbert Berger, navigated the ‘Ernst Kramer’ inland waterway vessel remotely from the operator’s stand at the Bremen Trade Fair Centre. The visitors were able to monitor how the vessel made its way in the Port of Duisburg and the Ruhr estuary via a live link – and everything was controlled remotely. To ensure that the skipper has a precise picture of the situation where the vessel is located, he or she can gain access to all the movement data of the sensor systems and cameras via radio waves from the operator’s stand. “It must be possible to control all the necessary functions for the journey from a distance. So far, this has included the rpm of the main engine, the transmission system, including the clutch, the rudder position as well as the transmission and configuration of the radar image and the radar pilot,” says Lars Reckers, the Technical Inspector at Rhenus Shipping Management, explaining the process. The test journeys enable those involved in the project to recognise which transmitted functions need to be refined or broadened, depending on the scenario. “To achieve this, we also have to see which regions where remote control is possible during the journey and where the reception for mobile communications creates problems” says Lars Reckers. “Authorisation for extensive test operations from the public authorities has therefore been an important step within the project.”
