Overview of the feasible methods for integration of large offshore platform

The feasible methods for integration of large offshore platform is summarized, such as block hoisting integration, giant segment hoisting integration, lifting-sliding integration, jacking-sliding integration, lifting-floating integration, floating crane integration and float-over integration. The advantages and disadvantages for each integration method are analyzed from the view of economy, safety and construction cycle. The typical cases of offshore platform integration with each method are enumerated. This study could be used for the shipbuilders as reference when construct similar offshore platforms.
