Offshore engineering equipment mainly refers to large-scale engineering equipment and auxiliary equipment in the exploration, exploitation, processing, storage and transportation, management, and logistics services of marine resources (especially offshore oil and gas resources), which have high technology, high input, high output, and high added value. It is characterized by high value and high risk. It is a high-tech complex of advanced manufacturing, information, and new materials. It has strong industrial radiation capabilities and has a great driving effect on the national economy. It is the basis for the development of deep-sea resources, the protection of marine sovereignty and rights, and the support of marine technology.

The design capability of marine engineering equipment and the strength of key parts manufacturing capabilities directly affect a country's ability to utilize marine resources and ensure marine security. my country's marine engineering equipment industry has been involved in all aspects of this field, such as product development and design, Supporting product manufacturing and general contract manufacturing, etc., but the overall level of my country's core supporting equipment design still needs to be improved, and more are still dependent on foreign companies. Let's take a look at the main development directions of key components of marine engineering equipment .
