Once the sub was raised and joined to the barge, it was carried back under the barge to the Russian Navy's Roslyakovo Shipyard in Murmansk. Once there, two giant, custom-manufactured pontoons were floated under Giant 4 to lift the barge to allow it to enter a floating dry dock with Kursk attached underneath. Once in the dry dock, the pontoons were pumped full of more air, lifting Giant 4 and allowing crews to remove the lifting cables and detach Kursk.
