FIELD: transport.
SUBSTANCE: invention relates to oil production in arctic waters, particularly, to ship for use therein. Proposed ship is available in two versions. In compliance with first version, ship can drill via drill water separation string extending from sea bottom well to turret arranged aboard the ship. Said drill water separation string can be detached from the ship located under its main line. At turret separation from the ship its bottom part submerges along water separation column to occupy equilibrium position whereat its surrounds at least partially a part of drill water separation column. In compliance with second version, proposed ship for drilling oil and/or gas production wells can be connected with at least one water separation column connected with turret coupled with ship of drill water separation column extending through the turret connected with the ship. Two lengthwise boards extend between ship fore and aft with ice belt made at, at least 50% of their length, the angle a of 45-80 degrees between ship hull and horizontal line.
EFFECT: lower load at anchoring and maneuvering devices, improved conditions of operation in arctic waters.
