摘要

A newly developed means of displacing fluids in the riser allows for simplified disconnects that save time and money. With hurricanes and loop currents in the Gulf of Mexico (GoM), semisubmersible rigs often must disconnect the riser from the blowout preventer (BOP) in a relatively short period of time. It is advantageous to drilling operations to ensure the riser is clean before it is disconnected. This minimizes drilling mud residue hazards on the deck and limits potential clean-up time before the riser can be reconnected.
