Ship Propulsion Equipment: A ship must be equipped with a complete set of compliant power plants and auxiliary equipment before it can navigate on water. These power plants include main propulsion plants, auxiliary power plants, steam boilers, refrigeration and air conditioning units, compressed air units, ship pumps and piping systems, water-making units, and automation systems. These electromechanical power equipment are mainly concentrated in the engine room, and the technical department specifically managing these equipment is the engine department. Main Propulsion Plant: The ship's main propulsion plant, also known as the "main engine", is the heart of the ship and the most important part of the ship's power equipment. It mainly includes: ship main engine, capable of generating

Dalian Shipyard: Ship departure from the dock
Departure from the dock: The captain should determine the method of departure from the dock based on the impact of wind direction, wind force, current speed, and current direction, as well as the water depth around the dock and the ship's mooring conditions, and inform the duty personnel; all duty personnel and personnel operating on the deck must wear life jackets; unnecessary ropes and obstacles outside the ship's hull should be secured; pay attention to the dock, berth, surrounding environment, ships ahead and astern, and the dynamics of passing ships. Departure should only commence when it does not impede the navigation of other vessels, and the departure signal should be sounded according to regulations. Engine operation should only commence after obtaining the consent of any accompanying tugboats. When a single ship departs from the dock in a river section with a current, under normal circumstances, the lines can be cast off according to the direction of the current,...

Dalian Shipyard: Ship Performance Introduction
Stability refers to a ship's ability to return to its original equilibrium position after being tilted away from it by external forces. Stability includes intact stability and damaged stability; intact stability includes initial stability and large-angle stability. The stability of general surface vessels mainly refers to transverse stability. Factors affecting a ship's stability include beam, waterline coefficient, freeboard, height of center of gravity, size and height of the side area above the waterline, and the quality of the sealing of the ship's openings. Buoyancy refers to a ship's ability to float in water under various loading conditions and maintain a certain draft and freeboard at the bow and stern. Based on the ship's weight and buoyancy

Current Status and Future Prospects of New Energy Power Systems for Ships
1. Types and Industrial Structure of Ship Propulsion Systems Ship propulsion systems, consisting of main engines (diesel engines, steam turbines, gas turbines, etc.), transmission systems (shafting, gearboxes, couplings, clutches, etc.), and propellers (propellers, omni-directional thrusters, side thrusters, etc.), are the most important and essential equipment on board ships. On average, their value accounts for approximately 35% of the total cost of ship equipment and about 20% of the total ship price. Currently, the world's various types of ships mainly use the following four propulsion methods: ① Steam turbine propulsion system - replaced reciprocating steam engines, and then replaced by diesel engines, currently mainly

Features of Dalian Ada Shipbuilding Co., Ltd.'s recreational fishing boats
Basic parameters of recreational fishing boats. Recreational fishing boats are a new type of fishing boat independently developed by our company. The hull has a long service life, is unsinkable, has good streamline (fuel-efficient), high stability (safe), large carrying capacity (high efficiency), and low maintenance costs. 1. High unsinkability. The hull structure of this boat is independently designed and developed by our company. The hull is a double-hull type, filled with high-buoyancy materials, and manufactured using special processes and the principle of an unbreakable tumbler. The hull is extremely rigid. This hull technology has been granted a national patent. This new type of hull structure can ensure that the boat can remain afloat even if it is damaged and completely flooded with seawater.
