A New Propulsion Standard. The Voith Linear Jet combines the best properties of propellers with the best properties of waterjets. Low installation complexity, low sensitivity to marine growth, sustained high efficiency across the vessels’ speed range and high bollard pull are borrowed from the propeller side. Reduced vessel draft, the ability to reach high speeds with high efficiency and low noise and vibration levels are borrowed from the waterjet side. Operating principle The Voith Linear Jet (VLJ) is a fully submerged custom-shaped deceleration/acceleration nozzle with a stator section...

High efficiency for (semi-) fast ships The Voith Linear Jet focusses on the area from around 20−25 4,00 knots up to 40 + knots. For this area, neither a propeller nor a traditional waterjet provides a 100 % satisfying solution. The 3,00 efficiency of propellers starts a steady decline at higher ship speeds when cavitation, noise and vibration levels all increase. Traditional waterjets only become efficient at speeds over 35 2,00 knots and have a dramatic low efficiency for any speed below 30 knots. In between these, the Voith Linear Jet— V = 10 kna delivers 1,00 —V= constant high efficiency...

Application Examples. The main application envelope of the Voith Linear Jet is between 25 and 40 knots. Outside this speed range other features like the reduced draft versus a propeller or a higher bollard pull can make the Voith Linear Jet the preferred option Wind service support vessel Bollard pull, maneuverability and transit efficiency are main operational requirements for a workboat like a wind service support vessel. Optimized nozzles for bollard pull are available in the VLJ range. To obtain favorable transit efficiency with these high-bollard pull nozzles, a vessel-optimized hull...
