The invention relates to the field of shipbuilding, and more particularly to floating facilities for the production of hydrocarbons from the bottom of the sea.Known vessels for hydrocarbon production, syrowski columns and pontoon, rigidly connecting the design and idler bearings fixed to the bottom (see, for example, application great Britain N 2142286, M CL6B 63 B 17/00; NCI B 7 A, 1985).The disadvantage of these known platforms is the impossibility of operating in ice conditions because of the possibility of the accumulation of ice between the support columns and the risk of damaging the operating and drilling risers, and, in addition, the complexity and duration (a practical impossibility) emergency care.Also known vessels for production of hydrocarbons, comprising a housing with a sentry gun, the axis of which is displaced in the nose relative to the fuselage mid-section, as well as technological and energy complexes, residential unit, propulsion systems and anchor system (see patent UK N 2300605, M. CL.6B 63 B 35/44, NCI B 7 A, 1993 - prototype).The disadvantage of this known vessel for production of hydrocarbons is the inability of its operation in ice conditions, especially when floating ice thickness of up to 1 meter or more, due to the placement of the propulsion units in the stern of the ship and lack protivogradovoy configuration of the hull lines.The technical result of the claimed invention is about the camping in the vessel for production of hydrocarbons, comprising a housing with a sentry gun, the axis of which is displaced in the nose relative to the fuselage mid-section; and technological and energy complexes, residential unit, propulsion systems and anchoring system, the fact that it is made with the possibility of inadvertent rotation of the nose for moving the grinding ice in the anchored state, and the case is made with simplified ship lines that meet the requirements for ships operating in ice, while the forward end of the installed propulsion systems protivoluchevogo type, and on the sides along the entire length of the hull mounted water jet device.In addition, it is also achieved by the fact that the body is made with double sides and double bottom in the area of the compartments with the technological equipment and the bottom of the fuel tank.In Fig. 1 depicts the inventive vessel for production of hydrocarbons, lateral view;
in Fig. 2 - section a-a of Fig. 1;
in Fig. 3 - section b-B of Fig. 1;
in Fig. 4 is a view of a of Fig. 1;
in Fig. 5 is a diagram of the destruction of the ice field of the claimed vessel.The claimed vessel for production of hydrocarbons includes a housing 1 with the turret 2, the axis of which is displaced in the nose 4 relative to the fuselage mid-section. The vessel is equipped with t the ETUI 8, anchor 9 and anchoring mechanisms (not shown) placed on the turret 2.The vessel is made with the possibility of inadvertent rotation of the nose 4 for moving the grinding ice 10 in anchored condition. The housing 1 has a simplified ship lines a (form body 1 is formed flat surfaces) that meets the requirements for ships operating in ice conditions. In the fore part of the housing 1 are propulsion systems 11 protivoluchevogo type, for example, installation Aziped (see "journal of Navigater", N 1, 98, p. 22), and on the sides along the entire length of the housing 1 are mounted jet device 12.To create additional resistance to ice loads and improve safety when working with hydrocarbons case 1 is made with double sides 13 and double bottom 14 in the area of the compartment 15 with the technological equipment 5 and the bottom of the fuel tank 16.For the optimal choice of the location of the axis of the turret 2 and scheme destruction of the ice field housing 1 of the vessel were carried out preliminary tests in a towing tank pool State research center of Russia - CSRI them. Acad. A. N. Krylov.After fixing anchor chains 8 to the anchors 9 on the seabed and the tension anchor chains mnogoletnjuju Parking at the field.When the operation of the ship in ice conditions, when the probability of occurrence in the field area of icebergs or piles of ice hummocks located in the fore part of the ship propulsion systems 11 Aziped during operation destroy large blocks of ice and turn them into melkovaty ice piles of hummocks. At the same time a jet of water emerging from the nozzles of jet devices 12 located along the entire length of the housing 1 together with its simplistic lines a, break and push away from the body creeps ice, which prevents the accumulation of ice formations, improves flow and creates favorable conditions for the inadvertent rotation of the vessel on the axis of the turret 2 nose 4 for moving the grinding ice 10 in the direction of ice loads.Tests conducted in the pool CRI them. Acad. A. N. Krylov showed the optimality of the choice of axis 2 sentry gun in the nose 4 from the fuselage mid-section, as by placing the axis of the turret 2 in the middle section of the reversal of the vessel under the action of drifting ice does not occur, and the optimal selection scheme destruction of the ice field according to the invention.The invention enables safe operation Dobychin what toroi shifted in the nose relative to the fuselage mid-section, as well as technological and energy complexes, residential unit, propulsion systems and anchor system associated with the turret, wherein the housing is mounted with a possibility of rotation about the axis of the turret nose for moving the grinding ice in the anchored state in the direction of ice loads under its influence, and the body is made with simplified lines, satisfying the requirements of the hulls of ice navigation and ice-breakers, in its nasal end of the installed propulsion systems for ice ships and icebreakers, and on the sides along the entire length of the hull mounted water jet device.2. Vessel under item 1, characterized in that the casing is made with double sides and double bottom in the area of the compartments with the technological equipment and the bottom of the fuel tank.
