The caisson could not simply be capped , because the oil pressure would blow its suction pile out of the sea floor .
沉箱不能完全地被盖帽,因为油压会把它的吸力桩从海底喷出来。
Various sizes of caisson will be built , including one 15 metres ( 50 feet ) or so in diameter , large enough to fit over a whole blowout preventer .
此外还将建造大小各异的沉箱,包括一个直径约为15米(50英尺)、足以覆盖整个防喷装置的沉箱。
Whether or not a caisson was used , the oil from the containment assembly would then pass through a manifold-a sort of switching yard for pipes-to one or more floating risers leading to the surface and held vertical by buoys .
