  • Drilling system having slot for underwater storage of BOP assembly
    Patent number: 9399891
    Abstract: A drilling system includes a derrick installed on a platform of a stationary floating structure. An activity forms a borehole in a sea-bed, and carries out installation of a casing pipe assembly and a BOP assembly in the formed borehole. A BOP trolley forms the BOP assembly together with the activity, and moves while supporting the formed BOP assembly thereon. A slot is formed on a work stand of a moon pool for underwater storage of the BOP assembly so as to extend parallel with the direction of movement of the BOP trolley, and suppresses shaking of risers when the BOP assembly positioned underwater is moved by the BOP trolley and the BOP assembly is moved to an underwater storage position.
