[0002] Ship management refers to the comprehensive management of a ship's technology, crew and business activities to ensure safe, efficient and economical operation of the ship. The core of ship management is to reduce operating costs through professional operation and maintenance, while ensuring the safety of life and property at sea and the protection of the marine environment. Good ship management can save costs for enterprises and improve market competitiveness.

[0003] Ship technical management includes ship maintenance, repair, inspection, and equipment fault analysis and processing, aiming to keep the ship in good technical condition and ensure the ship's seaworthiness.

[0004] Ship management is a complex and professional job. It is not only related to the safety and efficiency of the ship itself, but also affects the healthy development of the entire shipping industry. In the face of current market challenges and strict international regulations, the modernization and specialization of ship management is particularly important.

[0061] like Figure 1 As shown, the present invention provides a ship management method, comprising the following steps:

[0062] S1. Obtain ship information and analyze the ship information to obtain ship category information;

[0063] S2. Determine the ship maintenance frequency, maintenance content and maintenance technology based on the ship category information;

[0064] Determining the frequency, content and technology of ship maintenance based on ship category information is a complex and meticulous task. This requires not only considering the specific type and purpose of the ship, but also formulating a reasonable maintenance plan based on its operating environment and historical maintenance records. Through detailed analysis, a maintenance strategy that best meets the actual needs of each type of ship can be formulated.

[0065] Determination of ship maintenance frequency

[0066] Ship types and operating environment: Different ship types, such as cargo ships, passenger ships, tankers, fishing vessels, etc., have different operating environments and usage frequencies. For example, transoceanic cargo ships may require more frequent overhauls to cope with long voyages and complex marine environments.

[0067] Historical maintenance records: By analyzing the historical maintenance records of the ship, we can understand the parts that are prone to problems and the frequency of failures. This helps to formulate more personalized and accurate maintenance frequencies and ensure preventive maintenance before problems occur.

[0068] Planning of ship maintenance content

[0069] Hull structure inspection: including inspection of hull plates, welds, shafting and other major structures to ensure their integrity and strength. Especially for ships that sail in harsh waters for a long time, it is more important to focus on checking whether there are fatigue cracks or corrosion problems in their structures.

[0070] Mechanical equipment maintenance: covers the maintenance of key equipment such as main and auxiliary machines, electrical systems, navigation equipment, etc. Different maintenance cycles need to be arranged according to the frequency of use and importance of the equipment to ensure its efficient and stable operation.

[0076] Special maintenance requirements for different types of ships

[0077] Passenger ships: Due to the high density of people and strict safety requirements, passenger ships require more frequent inspections of fire safety systems and life-saving equipment to ensure they can operate effectively in emergency situations.

[0078] Oil tankers: Focus on checking cargo tanks and fuel systems to prevent leakage and environmental pollution. At the same time, due to the special nature of the cargo on oil tankers, special attention should also be paid to the inspection and maintenance of their loading and unloading systems.

[0079] Fishing vessels: Fishing vessels often operate in complex and changeable seas, and the durability and reliability of their hull structure and fishing equipment are the focus of maintenance.
