Six-leg wellhead platform jacket
The invention discloses a six-leg wellhead platform jacket. The six-leg wellhead platform jacket comprises six jacket legs; steel piles penetrate through the jacket legs; the jacket legs are vertically arranged; the upper ends of the six jacket legs are sequentially connected through supporting rods to form a regular hexagon I; the lower ends of the six jacket legs are sequentially connected through the supporting rods to form a regular hexagon II; the side length of the regular hexagon I is smaller than that of the regular hexagon II; drill conductors are arranged in the middles of the six jacket legs. Compared with common six-leg jackets, the novel regular hexagon symmetry arranged mode is adopted, so that environmental load capacity is reduced by about 20%; meanwhile, pile head force can also be reduced by about 20%; the safety factor of bearing capacity can be greatly improved, the weight of a pile foundation is reduced, and the construction cost is reduced; a left platform block and a right platform block are stably supported without extra module supporting frameworks. A single block can be mounted without an ultra-large floating crane, and offshore installation cost can be greatly reduced.
