Abstract
This paper started with a briefly introduction to the development history of the ice-resistant platform located in Bohai Bay, a major production area for CNOOC. Based on the previous structural design experience of platform under ice environments, the ice loading calculation method and new types of platform are proposed. This paper had further discussed the technical measures for the ice-resistant platform design. Learning lessons from engineering and production practice, the outstanding issues and challenges faced by the structural engineers are summarized and discussed. This paper may provide helpful reference to the future platform design in ice regions.
