Title: AN ARRANGEMENT FOR PROVIDING A FLOWABLE SOLIDIFIER INTO A SUBSEA HYDROCARBON WELL
Abstract:
An arrangement (3) for providing a flowable solidifier into a subsea hydrocarbon well (5) comprising a valve assembly (14) with an opening (15) to a well bore (16). The arrangement comprises a con- nection device (30) comprising a well control unit (40) comprising a lubricator device (44) with a first through opening (50), an inlet connector (42) comprising an inlet (53) for the flowable solidifier to a second through opening (52). The arrangement further comprises an elongated injection tubing (32) comprising a third through opening (54). The injection tubing is adapted to be displaced through the lubricator device to a certain position enabling the third through opening to receive the flowable solidifier from the inlet of the inlet connector (42) and extending into the opening (15) of the valve assembly so that one or more valves of the valve assembly are shielded from interaction with the flowable solidifier.
