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.

Dalian Shipyard explains common cargo transportation
Dalian Shipyard: Several common types of cargo ships Dalian Shipyard explains the common types of cargo ships. ① Traditional liner. This type of ship provides regular transportation services, usually carrying small or small batches of cargo. Cargo is loaded and unloaded using shipboard derricks or cranes, and cargo is stowed manually on board. ② Semi-container ship or semi-pallet ship. This type of ship carries bulk cargo and cargo on pre-loaded containers or pallets, relying on forklifts for stowage, and can also load containers in open holds or on deck. ③ Full container ship. It is built specifically for loading containers.

Dalian Shipyard explanation: Mechanical action corrosion on the ship's steel structure
Which shipyard in Dalian is good? ******Dalian Ada Shipbuilding Manufacturing Due to power supply or welding, violating operating procedures, causing leakage, which makes the hull a huge anode, causing large-scale corrosion. This corrosion is very surprising. For example, 4 landing crafts built by a certain factory were almost completely corroded through after one year of leaving the factory. The corrosion of mechanical action includes corrosion and mechanical wear, which accelerate each other. This includes impact corrosion, which is caused by liquid turbulence or impact. Cavitation corrosion, high-speed flowing liquid, due to irregular flow, produces cavitation, forming a "water hammer effect", often destroying
