Smaller vessels focus on lowering emissions

In support of small businesses aiming to achieve zero emissions, MARIN was recently involved in two studies for the smaller vessel segment.
The first was an inland container vessel, a combination of a ship and a barge, which is operated by Danser Container Line from Sliedrecht in the Netherlands. Measurements were conducted on board for months in order to obtain the mission profile of the twinscrew vessel. The second case was a small passenger vessel for Schlepp und Fährgesellschaft Kiel mbH, Germany. It is a twin-screw vessel with electrically driven propellers. Diesel generator sets deliver the power and feed a number of batteries as well. In the harbour this vessel can sail completely on batteries - a first step towards zero emissions.

Inland container vessel: in order to reduce emissions for the inland container vessel, electric propeller drives were considered in combination with methanol- driven generator sets. Although an electric driven propeller requires additional power compared to diesel-direct drives (less so if the mission profile is more variable), it offers the advantage of being able to switch the electric power supply type in a somewhat uncertain future.
