What is the Azipod propulsion system?
Azipod® is a gearless 360° steerable propulsion system, where the electric motor is located in a submerged pod outside the ship hull. By utilizing the Azipod® system’s maneuverability, marine vessels can direct thrust in any direction with incredible precision, saving time and fuel.
Which of the following reasons why ABB Azipod propulsion can save up to 20% of the fuel consumption than to traditional shaft line system?
Some of the key reasons why the Azipod® propulsion can save up to 20% of the fuel compared to a shaft line system are: No mechanical losses from a gearless system. Pulling propeller in an undisturbed wake field. No drag from appendices, rudders etc.
What are the different type electric propulsion system?
The electric propulsion system consists of a prime mover which may be of two types: Diesel driven. Turbine or steam driven.
What are the types of electric propulsion in system?
Of the ion and plasma drives there are three primary styles of electric propulsion that are used today. These are electrostatic propulsion, electrothermal propulsion and electromagnetic propulsion.
What is Z drive propulsion?
A Z-drive is a type of marine propulsion unit. Specifically, it is an azimuth thruster. The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction. This eliminates the need for a conventional rudder.
What is the difference between azimuth and Azipod?
Azimuth thrusters, also called azipods, are propellers mounted in a pod that provides thrust and steering by rotating the unit horizontally. Traditionally, vessels have propellers that provide forward thrust and a rudder that produces drag by turning, steering the vessel.
What is the current trend in ship propulsion systems?
The recent trend to design more efficient and versatile ships has increased the variety in hybrid propulsion and power supply architectures. In order to improve performance with these architectures, intelligent control strategies are required, while mostly conventional control strategies are applied currently.
Can electricity be used for propulsion?
Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means. The use of electrical power enhances the propulsive performances of the EP thrusters compared with conventional chemical thrusters.
Which ship is mostly used electric propulsion?
Electric propulsion systems are often used on ships such as icebreakers or oceanographic research vessels that take advantage of the aforementioned operational benefits, or large passenger cruise ships and others that emphasize cost and silent operation.
Which engine is more suitable for ship propulsion?
Both 2 stroke and 4 stroke engines are widely available in the market but for a large ocean-going merchant vessel, a 2 stroke engine is more commonly used as the main engine and has a much better market.
What are the five main advantages of the electrical propulsion system?
Increased payload through flexible location of machinery components. Environmental benefits from lower fuel consumption and emissions. High performance in harsh ice conditions due to maximum torque at zero speed. Reduces life cycle cost by less fuel consumption and maintenance cost.
How do electric propulsion systems work?
Electric propulsion technologies generate thrust via electrical energy that may be derived either from a solar source, such as solar photovoltaic arrays, which convert solar radiation to electrical power, or from a nuclear source, such as a space-based fission drive, which splits atomic nuclei to release large amounts …
What is on the C drive?
The C: drive, also known as your computer’s hard drive, has the important job of storing your computer’s operating system (Windows, Mac OS, Linux, etc.), as well as applications you use (e.g. Microsoft Office, Adobe, Mozilla Firefox) and files you download from the internet.
What is AZ drive used for?
What is a pod propeller?
A podded propulsor is defined as a propulsion or maneuvering device, which is external to the ship’s hull and houses a propeller powering capability. From: Marine Propellers and Propulsion (Fourth Edition), 2019.
What is the most efficient water propulsion?
The latest version of ABB’s podded electric propulsion system, Azipod XL, further increases vessel fuel efficiency to a level of up to 20% compared to modern shaft line propulsion systems.
