Wide Application of Energy-saving Technology for Ship Propulsion

1. Intelligent technology

At present, many shipping companies are beginning to organically integrate intelligent technology and propagation power propulsion technology, and use network information technology and scientific and technological means to monitor the diesel engine equipment and system control equipment in the ship power system in an all-round way. The use of intelligent technology can improve the fuel efficiency of ships on the one hand, and on the other hand can improve the level of electronic management of ships, which plays a vital role in the reasonable control of fuel consumption and the safe operation of ships.

2. Energy-saving technology of shaft generator

In addition to intelligent technology, the energy-saving technology of shaft belt power generation is also a new type of energy-saving technology for shipping. When the ship’s output power is in a stable condition, the shaft belt engine equipment inside the main engine can be used to effectively control the fuel consumption during the ship’s transportation, which is of great significance for improving fuel efficiency and saving fuel consumption. For example, during the normal operation of a shipping vessel, in addition to adding diesel fuel in accordance with the normal operation process, the shaft belt power generation technology can also be used for power generation, and the power generated by the shaft belt power generation is sufficient for the normal use of electricity in the cabin. In addition, the shaft belt power generation technology can reduce unnecessary fuel consumption expenditures, not only can effectively control exhaust emissions, but also save a lot of fuel costs for shipping companies.

3. Propulsion technology of the new ship

In addition to fuel efficiency, the shape of the ship will also affect the normal propulsion of the ship. In the current shipping industry, the more commonly used ship types are divided into the following types: ① longitudinal ship type; ② catamaran type; ③ ball bow ship type. Different shipping companies will choose the appropriate ship type based on the actual transportation situation. For example, a shipping company with a long-distance shipping route would generally choose a longitudinal vessel type. Because the ship type can effectively reduce the hull assistance in shipping, it can also change the angle of attack of the incoming flow, and can greatly improve the fuel efficiency of the fuel oil equipment, so as to ensure the stable and safe navigation of the ship.

4. Micro-foam energy-saving technology

In some large shipping vessels, some shipping companies will adopt micro-foam energy-saving technology in order to save shipping costs. For example: before a large shipping vessel sets sail, shipping companies will use micro-slit plates to reduce the friction of the hull. These micro-slit plates installed on both sides of the hull will form a layer of tiny bubbles when they encounter water. Under the action of these bubbles, the friction between the hull and the water body can be greatly reduced, which in turn can increase the shipping speed and reduce fuel consumption.
