The offshore drilling platform is important facility for offshore geo-technical investigation and mineral exploration. There are many types of offshore drilling platforms, and selecting a suitable one can get twice the result with half the effort. The modular shallow sea drilling platform provides powerful functions and a wide applicable range due to its many advantages such as easy manufacture, short manufacture period, low cost, convenient transportation, efficient installation, high mobility. In this paper, the design and manufacture of the modular shallow sea exploration platform are introduced, and its advantages are analyzed and summarized based on three application cases, which provides a reference for offshore drilling operations.
