Description

Technical Field

[0001] The invention belongs to the technical field of ship-shore connection operations, and in particular relates to a dual-redundancy self-checking system and method for a ship-shore connection system. Background Art

[0002] With the adjustment of global energy structure and the increasing awareness of environmental protection, liquefied natural gas (LNG), as a clean and efficient energy source, is increasingly widely used in shipping, power generation, industry and other fields. As the main means of transporting LNG at sea, the safety and reliability of LNG ships are of great significance to ensuring energy supply, maintaining the marine environment and promoting economic development. As an important interface between LNG ships and shore-based facilities, the performance and reliability of the ship-shore connection system are directly related to the safety of LNG ship loading and unloading operations.

[0003] In recent years, with the increasing number of LNG ships and the rapid development of the shipping market, the frequency and complexity of the ship-shore connection system have been increasing. Since the ship-shore connection system involves multiple fields of technology and complex operation processes, once a failure or improper operation occurs, it may not only cause safety accidents such as LNG leakage and fire, but also cause serious damage to ships and shore-based facilities, and even threaten the lives of personnel. Therefore, in-depth research on the ship-shore connection system of LNG ships and the development of self-test technology have very important practical significance and application value.

[0004] The research on the self-inspection technology of the ship-shore connection system involves the cross-integration of multiple disciplines, including mechanical engineering, automatic control, sensor technology, data analysis, etc. At present, new self-inspection technologies and methods are constantly being explored at home and abroad, such as: using the Internet of Things technology to achieve remote monitoring and real-time data transmission of the ship-shore connection system, so that the self-inspection work is no longer limited to the site, greatly improving work efficiency. At the same time, self-inspection systems based on big data and artificial intelligence technology are also constantly developing. These systems can predict potential faults and intervene in advance by learning and analyzing historical data, thereby further improving the safety of the ship-shore connection system of LNG ships. These self-inspection methods still have some shortcomings in terms of how to further improve the accuracy and reliability of the self-inspection system, how to reduce the cost of self-inspection and simplify the operation process, and how to adapt to ships of different models and specifications.
