Abstract: Complex products of offshore equipment are characterized by high market competition and strong periodicity. However, there is still a lack of in-depth analysis on how high-end deep-sea drilling equipment enterprises achieve rapid breakthroughs in key core technologies. This paper analyzes the dynamic evolution process of CIMC offshore drilling platform from late enter to rapid innovation leader from 2008 to 2023. (1) In the stage of strategic merger and acquisition, through technology merger and acquisition, the "structuring" and "competence" of resources are achieved, and the "response speed" of market information is built, and the rapid breakthrough of functional technology is achieved. (2) In the strategic focus stage, through the "integration" of internal and external resources and the "transformation" of the system, improve the "transformation speed" of platform knowledge and achieve a rapid breakthrough in performance technology; (3) In the strategy spillover stage, CIMC utilizes the international market through "leveraging" and "localization" to drive the overall upgrading of domestic offshore industry and improve the "pooling speed" of industrial knowledge. This paper summarizes the important role of resource orchestration in the process of realizing the rapid breakthrough of key core technologies. This paper proposes a theoretical model for accelerating breakthroughs in key core technologies of enterprise resource orchestration for complex product systems, expands the theoretical studies in two fields of resource choreography and absorption rate, and provides useful enlightenment for the policy-making and enterprise practice for accelerating breakthroughs in key core technologies in complex product systems in our country.
