Abstract:
A method for connecting a lower marine riser package to a lower blowout preventer stack. The method includes lowering a frame of the lower marine riser package toward a frame of the lower blowout preventer stack such that a first half of a feed-thru component contacts a second half of the feed-thru component; floating at least one of the first half of the feed-thru component or the second half of the feed-thru component while the frame of the lower marine package is further lowered toward the frame of the lower blowout preventer stack; and engaging the first half of the feed-thru component to the second half of the feed-thru component after further lowering the lower marine riser package toward the lower blowout preventer stack.
