Fixed platform refers to a platform that uses piles to fix a structure on the seabed or sits on the seabed by its own weight.
A fixed drilling platform is a drilling platform that is directly fixed on the seabed. The platform is fixed on the seabed through a pipe frame structure. The position is fixed during the entire service life and cannot be moved. It is mainly used in oil fields with industrial oil flow, and the general working water depth is about 20m. Some drilling and production integrated fixed platforms have a working water depth of more than 90m, but the construction cost of the platform is relatively high.
The advantage of a fixed drilling platform is that it is stable and the sea surface weather conditions have little influence on it, and it can be used as an oil production platform after completion of the well, and its use time is greatly increased. However, it has poor flexibility, cannot be transported in time, and is expensive to work in deeper waters. The gravity platform is suitable for shallower water depths, the jacket type platform is suitable for slightly deeper water depths, and the tension and rope tower platforms can be used in deeper waters.
