Title:
TURRET SUPPORTING APPARATUS OF TURRET MOORING SHIP
Document Type and Number:
Japanese Patent JPS61155086
Kind Code:
A
Abstract:
PURPOSE:To enable a load to be uniformly borne by a number of supporting rollers for supporting a turret in the radial direction thereof by grouping the rollers into a plurality of groups and driving all the rollers by a common hydraulic supply system, thereby uniformly distributing the load on the circumference of the turret. CONSTITUTION:A number of supporting rollers 4 to support a turret in the circumference thereof are grouped into a plurality of groups X1-X6 each consisting of a plurality of the supporting rollers and respective hydraulic cylinders 5 for the respective groups are driven by a common hydraulic supply system. A hydraulic circuit 6 of each group is connected to a common hydraulic tube 7 through a selector valve 8. An accumulator 10 becoming operative by another selector valve 9 absorbs the vertical movement of the supporting rollers 4. Thus, the breakage of some supporting rollers due to an unbalanced load from the turret is prevented, thereby uniformly bearing a broadly distributed load.
