The purpose of the present study is to analyse the fuzzy reliability of dual-fuel steam turbine mechanical propulsion conventional (DFSMC) system of LNG carriers for components with different membership function by applying Tω(weakest t-norm) based generalized fuzzy lambda-tau (TBGFLT) technique.
The propulsion system used to drive the craft through water may be wind but for most large crafts, it is some form of mechanical propulsion.
It's the sail, steam and mechanical propulsion that make the lines of the ship, the curve of the bow, the shape of the transom and the general profile, that is the thing that attracts your attention.
Maritime technology has begun to replace mechanical propulsion by electric propulsion.
While most ships built today feature mechanical propulsion and a separate electric power system, for more than 20 years, there has been a trend towards integrated electric propulsion where a single set of generators provides electric power for both propulsion and other loads aboard the ship.
Diesel mechanical propulsion with controllable pitch propellers can provide high fuel efficiency with good manoeuvrability.
In terms of efficiency the hydro-mechanical propulsion system is superior to the other ones, reaching a maximum efficiency of 95% compared to 85% for electric and hydraulic power trains [3, 4].
The mucosa is surrounded by circular and longitudinal smooth muscle layers that promote the mechanical breakdown and propulsion of food within the GI tract, through coordinated contraction and relaxation events termed peristalsis.
This paper presents a mechanical actuator for the biomimetic propulsion of swimming devices and the experimental study of the effect of the caudal fin elasticity on the overall performance.
This modality effectively exfoliates the outer layers of the epidermis using the propulsion of a mechanical medium, such as aluminum oxide microcrystals, at the skin through a handpiece.
