The Rizhao Port transformation and upgrading project is China's largest water transport project currently under construction. The transportation of giant caissons – large, hollow watertight chambers used in construction work under water or as a foundation – is a key and critical procedure in the land reclamation and port construction process.

Join CGTN's livestream as we take you to explore the structural features of the caissons, the principles behind horizontal lifting, the operating mechanisms of floating dry docks, and the tailored geological solutions driving China's mega-waterway infrastructure.
