FIELD: shipbuilding.
SUBSTANCE: invention relates to the field of shipbuilding, in particular to the design of a floating drilling rig. A floating drilling rig is proposed having a hull, a main deck, an upper cylindrical section extending down from the main deck, an upper truncated-conical section, a cylindrical narrowed section, a lower ellipsoidal section extending from the cylindrical narrowed section, and a protruding stabilizer attached to the lower outer part of the lower surface. The upper truncated-conical section is located under the upper cylindrical section and is held above the waterline during transit draft and partially under the waterline for the working draft of the floating drilling rig.
EFFECT: proposed floating drilling rig has improved hydrodynamic characteristics.
