Method of cross lifting and lowering into water

FIELD: shipbuilding.

SUBSTANCE: invention can be used in shipbuilding and ship repair enterprises in inspection and repair of ships. For transverse lifting and lowering into water before or after start of ship dock along perimeter of territory, which is derived and there is a vessel, and with several sides dock set dense watertight enclosure forming a closed territory. Inside dock water is pumped to level above open dock side. Water is lowered and ship is lowered at keel blocks. Ship is lowered by raising water level in dock and adjacent territory together with ship to ship surfacing. Vessel is discharged on territory dock and water is lowered to initial level.

EFFECT: reduced labour input during lifting and lowering of ship into water.

FIELD: transport.

SUBSTANCE: proposed structure comprise beach wall, floating balloons with ballast system and hinged platforms secured at the wall by pivot joints with horizontal turn axis tat feature concaved cylindrical bearing surfaces of one curvature radius whereat wheeled tricks are mounted. It comprises at least two rows of platforms with parallel rotational axes spaced apart over beach wall height. Platforms of every row incorporate turn control mechanisms, edge guards to limit carriage displacement and are shifted relative to platforms so that at mutual turn they are located between platforms to be conjugated with said cylindrical surface. Beach wall is equipped with recesses to house turning platforms.

EFFECT: higher performances.

FIELD: transport.

SUBSTANCE: invention relates to ship building and repair, particularly, to device used for ship launching from shore slip or rising it thereto. Proposed device comprises ballastable floating pontoon including ship transfer tracks to be coupled with those at inclined shore slip. Pontoon body is equipped with internal wedge-shaped recesses to house said ship transfer tracks.

EFFECT: simplified design and process.

Launching complex // 2313468

FIELD: shipbuilding; ship launching complexes.

SUBSTANCE: proposed launching complex has slip for ship mounted on its supports made in form of launching trolleys with technological pads mounted on them. CG of support areas and ship's CG are located in one vertical plane of slip which is perpendicular to ship's BL. Heights of technological pads are determined from the following formula: hi= hmin + Vi, where hi is height of technological pad; hmin is minimum height of technological pad, constant for all supports; Vi is height of varying part of technological pad equal to sag of each support selected from calculation of total strength of ship placed on two rigid supports under action of distributed weight loading of ship equalized by reaction forces in sections of slip intermediate supports.

EFFECT: extended operational capabilities of launching complex without its updating at retained local and total strength.
