... We investigate the feasibility of using Magneto-Hydrodynamics (MHD) to implement a propeller-less propulsion system. The basic principle behind MHD is to use the (Lorentz) force produced by the interaction of electric and magnetic fields to generate thrust on a conducting fluid in motion...

... for the propulsion system and the power generation on board. These two aspects significantly affect the internal layout of the pleasure craft, which needs to ensure high comfort levels, hence appropriate internal habitability. With this in mind, internal spaces have been selected as constraints for the hull form...

... Icebreaker technology has undergone significant advances over the last 25 years. This development have led to building of new generation icebreaking fleet: both icebreakers and ice capable cargo vessels. This article will concentrate on some key aspects in designing of optimum propulsion system...

... When simulating a ship propulsion system, it is often required to evaluate various characteristics of a ship propulsion system and the selected modelling approach changes according to the goal of the simulation. For example, data-based models are sufficient for simulations of steady state...

... the response of the propulsion system in ice conditions are to be made because the consideration and addressing the complex nature of a propulsion system in practical design are impossible for many reasons. Third of all, various underlying uncertainties in the input data put a shaft designer in situation when...

... Optimized shaft alignment and high-quality construction are important guarantee of safe operation for propulsion system on board. Twin-propulsion system arrangement with certain degree skeg is more and more adopted by large LNG carrier. The global FE model with local refined mesh was used...
