In floating offshore operations, the choke and kill lines exit the subsea BOP stack and then run along the outside of the drilling riser to the surface.

在进行浮动的海上作业时，节流和压井管线从水下防喷器组出来，之后沿钻井隔水导管外侧面到达水面。

When drilling in deepwater, once the Subsea BOP system breakdown, the BOP and riser must be pulled to the surface and cause great economic loss.

在深水钻井作业中，一旦水下防喷系统发生故障，就必须将防喷器组和隔水管起出水面进行维修，将造成上百万元的损失；
