Application of Marine information technology in wreck salvage project

Aiming at the practical application of Marine information technology in the construction of large-scale Marine salvage project and the intelligent and information management of Marine construction project, this paper analyzes the application form of Marine information technology and the characteristics and requirements of shipwreck salvage project. Taking the "Sewol" sunken ship salvage project as an example, the methods of integrated display of site data information and real-time virtual reproduction of salvaging process developed during the salvaging process, as well as the working principle of the visualized integrated monitoring system for sunken ship salvage are expounded. The key technology role of Marine information technology in shipwreck salvage, Marine emergency rescue and so on is fully illustrated by the combination of vertical decomposition and separation mode, fusion mode and construction Angle of underwater three-dimensional system.
