Extremely quiet travel by ship

In the field of modern shipbuilding, acoustic optimization measures are more than just a cosmetic adjustment. Low noise emissions are a precondition for use at sea in the case of research vessels, for example. After all, being able to hear warning signals and understand what others are saying everywhere on board is a must for safety reasons alone.

Electric marine propulsion systems are technically sophisticated and low in emissions – and are therefore seeing increasing demand as equipment for research vessels. The power electronics that are used today between the on-board generators and wiring system make this possible with improved frequency stability and efficiency. High-speed motors with a reduction gear unit are an alternative to a direct electric propulsion system with its large, heavy motors, which rotate at propeller speed.

This concept is implemented perfectly by the RENK AED, in which the electric motor and gear unit are installed on the same raft, which in turn is mounted on flexible supporting elements. Special advantages include a compact design, easy installation, a low weight, and unparalleled quiet operation. The advanced friction coupling (AFC) switches off the main reduction gear unit while the AED is operating to prevent noise from the trawls. RENK AED can also help to generate power on board by serving as an auxiliary drive during sea transport.
