Hydrodynamics Helps Design New Thrusters

Dutch marine equipment supplier Vetus den Ouden turned to countrymen at the Maritime Institute Netherlands (MARIN) for collaboration in developing their latest bow thrusters. In working together with the noted hydrodynamics laboratory, Vetus has optimised bow thrusters performance by uniquely shaping propeller blade profiles, resulting in little or no cavitation and thus minimal noise.

The Vetus – MARIN collaboration has cut sound pressure in half, improved thrust force by up to 9% whilst reducing power consumption by up to 10%. The new thrusters provide equal thrust to both port and starboard and, as they use only a single propeller, allow the shortest possible tunnel length. MJ Information No: 22331
