The marine industry is seeing an increasing number of vessels equipped with electric propulsion opposed to traditional mechanical propulsion. Electric propulsion has been shown to be advantageous in various land applications such as locomotives and road vehicles however in the marine setting the highly variable hydrodynamic load exposes the electric propulsion system to extreme load conditions. This...
Cylinder deactivation in diesel engine is proposed in the industry, where under part load condition engine cylinders will be deactivated, leading to less fuel consumption, losses and less emission. But the main bottle neck for such deactivation process is excitation of mechanical systems which affects the reliability of sensitive mechanical components. Hence the investigation of cylinder deactivation...
Electrical propulsion is gaining popularity in the marine industry, because of its good energy management and better dynamic performance. An azimuth thruster driven by an electric motor is a common configuration found in modern electric propulsion systems. In recent years failures relating to bevel gears and bearings in azimuth thruster drive train failures were reported in the marine industry. The...
