Title: EXPLOSIVE DISCONNECT
Abstract:
A coupling system includes a lower marine riser package having a connector at a bottom end and at least one blowout preventer pressure control element coupled to a wellhead and having a connector at an upper end. Explosively frangible fasteners are used to couple the connector on the lower marine riser package to the connector on the at least one blowout preventer pressure control element. A method for separating a lower marine riser package from a blowout preventer coupled to a subsea wellhead includes closing a least one pressure control element in the blowout preventer. At least one explosively frangible fastener coupling the blowout preventer to the lower marine riser package is detonated. The lower marine riser package is then lifted from the blowout preventer.
