  • Arrangement for providing a flowable solidifier into a subsea hydrocarbon well
    Patent number: 11261688
    Abstract: An arrangement is for providing a flowable solidifier into a subsea hydrocarbon well comprising a valve assembly with an opening to a well bore. The arrangement has a connection device comprising a well control unit with a lubricator device with a first through opening, an inlet connector with an inlet for the flowable solidifier to a second through opening. The arrangement further has an elongated injection tubing with a third through opening. 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 and extending into the opening of the valve assembly so that one or more valves of the valve assembly are shielded from interaction with the flowable solidifier.
