FIELD: shipbuilding.SUBSTANCE: method of holding underwater drilling systems above the bottom surface of seas and oceans comprises common housing and separate elements of pressure vessels of spherical shape and screw propellers. Screw propellers functionally connected with drive to generate driving force and helical shape. One end of screws with the possibility of joint rotation coaxially fixed with corkscrew and the other end to turn in vertical plane is functionally connected with reduction gear drive. Reduction gear drive is tightly fixed inside hollow spherical vessel, which is made with hole in lower part and after immersion into water filling oil.EFFECT: invention can be used for production of tight pressure vessels activating lifting force of overwater transport.1 cl, 2 dwg |
