Abstract
A surface joint provides a sealing interface between pipe rams or variable-bore rams of a surface blowout preventer and a landing string. The surface joint may be used in a system including the surface blowout preventer, a subsea mudline closure device having a conventional configuration without additional pipe rams or variable-bore rams used to close on a slip joint, and a high-pressure riser.
