The propulsion systems fitted to a ship enable it to navigate the water currents. Hence, it is one of the most important systems. Over time, the propulsion system has evolved in order to ensure a safer and cleaner underwater ecosystem. Also, new technologies are being designed to control fuel emissions, by using the fuel economically. Hence, if you are planning to buy a ferry for sale, first take a look at the different types of marine propulsion systems used in ships.
Top Marine Propulsion Systems Used in Ships
There are various types of propulsion systems fitted to the ships, since propulsion system is vital for ships’ movement; it becomes important to know about the different types.
1. Wind Propulsion
This propulsion system uses wind-capturing equipment or sails to change the vessel’s path accordingly. Since it is powered by wind itself, the tool is a great alternative for propulsion systems that release considerable amounts of carbon dioxide. However, the wind propulsion system has one downfall, because it requires a constant windy environment, it becomes a problem to power big commercial ships. The popular types of wind propulsion are kite propulsion and sail propulsion.
2. Diesel Propulsion
Most vessels, whether small boats or large ferries, use the diesel propulsion system to navigate. It is currently one of the most commonly used propulsion systems. The diesel propulsion converts the thermal energy into mechanical energy. If you compare steam turbine propulsion with diesel propulsion, then the latter is more efficient than the former.
3. Gas Turbine Propulsion
The most common application of gas turbine propulsion systems is on naval ships. They offer a significantly faster speed, which is advantageous if the ship is ever attacked. For greater efficiency, some ships use a gas turbine system in addition to a steam turbine. To give an example, both large merchant ships and cruise ships utilize gas turbines.
4. Nuclear Propulsion
Naval ships have been using nuclear propulsion for a while now. It generates energy using the idea of a nuclear explosion. The vessels can be powered by a nuclear fission process produced by a number of miniature nuclear reactors. Modern commercial ships are currently being built with nuclear propulsion in mind. This nuclear reaction’s energy can also be used to power the ship with electricity. In terms of fuel efficiency and cost, nuclear propulsion technologies offer a lot of potential.
Do you want to invest in a ferry for sale? Then, make sure that you get in touch with a top shipbroker who can guide you properly and help you invest in a top-model ship with the latest propulsion system.
5. LPG Propulsion
Liquefied natural gas, commonly referred to as LNG, is a substitute marine fuel that has gained appeal owing to its great fuel efficiency and remarkably low greenhouse gas emissions. LNG fuel and bunker fuel are used by LNG marine propulsion systems to transform chemical energy into mechanical energy. It is a more sustainable option.
6. Fuel Cell Propulsion
This system uses power generated by batteries and fuel cells to drive the vessel forward. Without using conventional combustion techniques, hydrogen is often the main fuel component used to transform the fuel into electrical energy. As a result, fuel cell propulsion is a clean, green technology that lowers pollutants and carbon emissions. It offers an environmentally friendly substitute to other marine propulsion technologies.
Conclusion
These are some of the most common types of propulsion systems that a ship is equipped with. Understanding what these propulsion systems can offer will enable you to choose a ship that can operate at maximum efficiency. Hence, if you are interested in purchasing a ferry for sale, then in that case, make sure that you invest in the one that matches your velocity requirement. It is often suggested by experts to look for vessels that are fitted with more than two propulsion systems and can be used together. If you are looking for such a vessel, then it would be wise on your part to partner with a top shipbroker.
