Patent
·
OSTI ID:6043752
A marine riser system is connected through flowlines and a moonpool plug assembly to a marine vessel. The moonpool plug assembly, when removed from the marine vessel, maintains a fully submerged position due to its having a buoyancy which is less than the net weight of the flowlines to which it is connected.
