Due to the loads of wind, wave, current, ice and so on, the bucket foundation platform with self-construction should have sufficient supporting stability on ocean bottom for the safety operations to the platform. According to the research object and the environment parameters, it is determined that the structure type of the self-construction bucket foundation platform that has the operation ability in 17 m of water. The calculation methods are discussed, including the anti-sliding stability, anti-overturning stability and vertical stability. The calculation results show that the platform has sufficient supporting stability and is safety when sitting on ocean bottom.
