Move the bop to the moonpool door and attach the marine riser 将防喷器吊到滑动门上，接上隔水管。
2.
Pick up the marine riser 吊出隔水管。
3.
Set the riser tensioners to support the riser and lower marine riser package ( lmrp ) 调定各隔水管张力器，以支承隔水管和隔水管下部插入总成。
4.
Marine riser is a steel or flexible pipe which transfer well fluids from the seabed to the surface 采油管就是从海底输送油气至海面的钢管或软管。
5.
It shows that the modal shape and mode frequency are highly coupled with the viv response of a marine riser with low mass ratio 该模型的计算结果表明，立管的模态振型、模态频率与涡激振动响应高度耦合，并且对于低质量比的情况尤为明显。
