A string includes a pipe that is connected to an expansion mechanism and a retrieval tool that is connected to the pipe above the expansion mechanism. The retrieval tool includes a carrier that can selectively latch on an expandable liner and one or more actuators. The retrieval tool can ensure latching of the carrier while the expandable liner is above the Blow-out Preventer. The retrieval tool can prevent accidental latching of the carrier on the expandable liner during the expansion of the liner. By manipulating the pipe, the retrieval tool can force the carrier's release from the expandable liner.
